U4) A JOURNAL OF PRACTJCAL INFORMATION IN ART, SCIENCE, MECHANICS, AGRICULTURE, CIIEMISTRY, AND MANUFACTURES. VOL. IV.---NO. 1. NEW YORK, JANUARY 5, 1861. NEW SERIES. Unless we are mistaken in our ol)inion, the hiven- tion which we here illustrate is one of the most valu- able that has been made in many years. In view of the immense number of bricks that are annually man- ufactured and used, inventors have long since recog- nized the importance of a brick-making machine, and a great many patents have been issued for inventions in this department. It was early seen that the real desideratum was a machine which should mold the clay in a comparatively dry state, so us to make what arc technically called prcssed brick ; but the very rigid nature of the material has proved a formidable obstacle to the production of such a machine. We have known a very ingenious mechanic, after spend- ing a great deal of time and money in trying to con- struct a machine that would mold brick from dry clay, to abandon the attempt in despair from the rigid nature of clay, which, he said, was as difficult to press into a mold as cold lead. But, in Crarys machine, while the pressure is one of the most powerful capable of being produced by mechanism, it is brought to bear on only a portion of the brick at a time, and the clay is crowded into the mold with a peculiar kneading mo- tion, which fills the edges and corners of the molds in the most perfect manner conceivable thus producing a brick which, in smoothness, hardness and strength, is greatly superior to those made by the ordinary wet molding processes. Besides this, the rotary motion of the machine enables it to be run with such velocity as to give it a capacity of production which would be deemed incredible without a description of its con- struction, which we will proceed to give. Of the annexed cuts, Fig. 1 is a perspective view of the whole machine, and Fig. 2 a vertical section of the Inincipal parts. The molds are formed in the in- pressure, and afterxvard each portion in turn as it ncr or concave side of the revolving ring, A, and the passes under the roller, while, at the same time, suffi- clay is pressed into them by the revolving roller, B. dent pressure is exerted on the other portions of the The quantity of clay fed into each mold depends upon brick to prevent the clay from yielding upward, and the angle, C, between the mold ring, A, and the press the peculiar rolling motion of the press kneads the roll, B, and this angle must accordingly be adjusted to material into the edges and corners of the mold in the most admirable manner. The rollers, D and E, sup- port the molds and sustain the pressure. As the molds are carried up by the revolution of the ring, A, the steel blade, F, scrapes off the surplus ma- terial. The bottom of the mold consists of a stiff iron plate, g, which has a motion like a piston or plunger to discharge the brick a shank, A, being attached to it to serve as a piston rod. When the mold reaches the upper portion of the wheel, the brick is pushed The bricks fall upon an endless belt, which carries out of it by the shank, g, coming under the roller, I. them out to the kiln. The bottoms of the molds are drawn back into place by the pins which pass through the shanks, h, and rest upon the eccentric plates, J. It will be perceived that the bricks are flat upon one side and slightly concave on the otherjust the form that is requisite for a perfect brick. The roller, K, is only brought into operation when it is desired to give a very smooth polish to the concave surface of the brick. The pulverizing apparatus is an entirely separate in- vention, and is shown in Figs. 1 and 3. It consists of three rollers in a hopper, running with unequal mo- tions the roller, L, revolving about twice as fast as M, and M about twice as fast as N. This produces ex- actly the crumbling kind of pressure required for pul- verizing clay. Beneath the hopper is a horizontal shaft carrying arms placed spirally, which, by its revo the thickness of the brick, vy making the roller, B, of a proper size in proportion to the ring, A. As the clay falls down into the angle, C, it fills the molds as they pass along under it, and as they come under the roller, B, the clay is pressed into them the forward edge of the brick first receiving the full force of the \ ~\ N \, \%, CRARYS IMPROVED BRICK-MAKING MACHINE. 2 lutions, sweeps the ground clay along out of the hop- per into the screen, 0, through which it falls into a chute which carries it to the bottom of the elevator, P. From the elevator, P, the material is (liseharged l)y a chute into the angle, C, Fig. 2. The spiral arias of the shaft at the hottom of the hopper not only per- form the office of moving the clay along to the screen, l)Llt they also mingle it thoroughly with the sand which it is necessary to mix with pure clay in order to make ~ood brick. In case the clay contains pehhles to C he taken out, the screen may he placed ahove the pul- verizing hopper. This machine is the invention of a man who has been engaged for iwtny years in the manufacture of brick on an extensive scale. Having a large con- tract for furnishim~ brick to he used in the construction of Fort Jefferson tue largest fortification in the Unitell States, situated on the island of Tortugas, off the coast of Florida he had one of these machines constructe(l, and has subjected it to a thorough test. He says that it will, when running quite slow enough, turn out 40,000 bricks per day, requiring about a ten- horse poxver engine to drive it; that in New York it takes seventy hands to set and hum 40,000 bricks per day; but that, with his machine, twenty hands will do the work. Ilie brick, too, made l)y his machine are smoother, imetter finished and more solid than those made in the ordinary way ; they have been thoroughly tested in regard to strength and power of resisting pressure, by the engineers who have charge of Fort Jefferson, an(l found to be far superior in these respects to or(liuary brick. But perhaps the most important feature in this machine is the facility which it gives of carrying on the manufacture of bricks in all weather. As lie molded forms require no drying, but may be place(l at once in the kiln as they come from the ma- chine, it is only necessary to provide a supply of clay under cheap sheds to keep the works in constant oper- ation. T he patent for this great invention was granted through the Scientific American Patent Agency, Aug. 17, 1858 ; and further information in relation to it may be ol tamed by addressing the inventor, J. W. Crary, at Pensacola, Fla., or John H. Keyser, No. 2 Bible house, Ninth-street, corner of Fourth-avenue, New York. Bisuiphide of Carbon in Coal Gas. Tt is xvell known that gas, when made from most kinds of bituminous coal, contains a minute quantity of sulphur, even after its most careful purification. In order to ascertain how much is contained in the Lon- (ion gas, Professor A. M. Hoffman was appointed to make experiments by a committee of the House of Lords on Education. The object of the inquiry being to ascertain the quantity of sulphurous acid capable of l)eing formed by the combustion of the gas, an exceed- ingly small jet of gas, carefully washed with acetate of lead and measured by an accurate experimental meter, was burned in a large two-necked glass globe. Through one of the necks the gas tube was conveyed into the globe, while the other, fitting into a condenser, carried off the products of combustion into a two-necked re- ceiver. 1o establish a current of air, the receiver was connecte(l xvi th a water current aspirator; a couple of Woolfes bottles, containing water or dilute ammonia, being inserted for the purpose of fixing any trace of sulphurous acid which might escape condensation with the water in the condenser. The experiment being terminated, the liquids in the receiver and in the wash bottles were unite(l, oxy(lized with chlorine, and pre- cipitated with chloride of barium. Four experiments were made, and two cubic feet of gas burned on each occasion, when it was found that 9.04 grains of the hi- sulphide of carbon were in every 100 cubic feet. SIZING FRENch PAPER. At the celebrated paper mill at Essone, in France, the writing and photographic papers are sized with resin soap, as follows:Good white American resin is placed in a moderately sized boiler and melted; then some caustic alkali in solution is added, which combines with the resin and dissolves it. This resin soap is now conducted to another vessel containing boiling water, where it is allowed to settle to permit the impurities to fall to the bottom. The clear is used to mix with the paper pulp, after which some thin starch, contabsing a portion of alum in solu- tion, is also added. rl7his is also similar to the Ameri- can mode of sizing paper. ELECTRICITY AND SOME OF ITS PRACTICAL APPLICATIONS. AarLcaE I. We propose to give a series of articles on such ap- plications of electricity as are known only to a very limited number of persons. Much of the information which these articles will comprise cannot be obtained without the perusal of a great number of works; and some of it cannot be obtained in any other publication whatever. To all young men who desire to gain a full knowledge of electricity, this series of articles xviii be indispensable. nATTERIEs. The source of voltaic electricity is the galvanic bat- tery. Of this instrument, there are several forms in use, each of which has its merits and defects. One that is easily managed and well adapted to the wants of the general experimenter is Daniells. This battery furnishes electricity, either of quantity or intensity, with gre~t facility. Smees battery is simple in con- struction and theory, but practically it is expensive for, after it has been in operation for a short time, the mercury used on the zinc plates attacks the silver plate, and the resulting amalgam falls to the bottom of the cells. Groves and Bunsens batteries are both powerful, but they render necessary the use of nitric acid, which stains the hands of the operator, and they are expensive in working. Daniells battery is liable to none of these objections, and it has, moreover, the advantage of furnishing a constant and uniform cur- rent for hours. It should be borne in mind that in all batteries there is, for each equivalent of zinc con- sumed, a certain amount of electricity evolved; but this consumption of zinc includes only that which is employed in developing the current; and the fact that one battery has used a larger amount of zinc than another in a given time does not always show that it has given off more electricity. In Groves and Bunsens batteries, the nitric acid, from a variety of causes, finds its way to the zinc, which is consumed by direct chemical action, without any useful effect being produced ; thus in- volving a waste of both zinc and acid. The best method of preparing the zinc plate of any battery is to plumage it in dilute sulphuric acid until a brisk effer vescence takes place upon its surface; it should then be taken from the solution, and mercury poured on its surface in small quantities and evenly spread by a rag of cloth. If this process is thoroughly gone through not omitting the edges of the platethe whole sur- face of the zinc will present a bright silvery appear- ance, and, when plunged in dilute sulphuric acid, no effervescence xviii take place. After the zinc has been xvell anaalgamated, it may be placed in the proper po sition and the exciting liquid poured upon it. In all practical batteries, the zinc is called the positive plate or element, and the other plate the nega- tive. If these two plates are connected by means of a xvire or other conductor, the current will pass from the positive through the liquid to the negative plate; and thence through the conductor to the positive plate again. When a number of cells have all their positive plates connected xvith each other, and also all their negative plates, it xviii be seen that the whole battery is equiv- alent to one large cell. The current produced by such an arrangement is called one of quantity, and is char- acterized, ilrstly, by its inability to traverse a very long conductor; secondly, by its power to produce powerful heating and magnetic effects when the conductor is not too long; thirdly, by its inability to traverse a poor conductor. It has also many other characteristics. When each positive plate is connected with the next negative, and the first and last plates attached to the polar wires, a current of intensity is produced. The chief characteristic of this current is its poxver to pass very long or poor conductors; and, for this rea- son, it is very useful for the telegraph and other pieces of apparatus xvhere a considerable resistance must be overcome. When a current is passed through a conductor, it ex- periences a certain resistance. This resistance increases directly with the length of the conductor, and also varies directly according to its area. If, for instance, a xvire has a certain conducting power, and we double its length, its conducting poxver is reduced to one-half its fornaer capacity; and so on, indefinitely. The con- ducting poxver of a xvire, xvhich forms a part of any machine or piece of apparatus, should always be pro- portioned to the ananunt of electricity xvhich is. to pass through it, or the battery should be adapted to the in- strument. If all the current cannot pass the con- ductor, the size of the battery should be reduced until that point is reached. The Balance of Trade. The folloxving statement of the exports and imports of the United States, for the last five years, is taken from the report of the Secretary of the Treasury: Year Exports. Inports. Ex. seer Isi. 1836 $326,964,918 $314,639,942 $12,324,976 1837 362,949,144 360,590,141 2,039,003 1535 324,644,421 282,613,130 42,031,271 1859 356,789,462 388,768,130 18,021,332 1860 400.122.296 362.163.941 37,938,333 Tsr 5 years. $1,771,470,241 $1,659,073,304 $112,394,937 Several of the papers are parading these statistics as proof that the balance of trade is in our favor. The Balance of Trade is a delusion that has to be ex- ploded about as often as perpetual motion. The whole thing depends upon the way the books are kept at the Custom Houses. A cargo of wheat is brought into New York for $100,000 and sent to England, xvhere, the freights and profits added, it is sold for $140,000. After deducting the freightsay $20,000the balance is expended in hardxvare, & e., and brought to Nexv York, xvhere, xvith the xveighmt and profit added, it is xvorth, say $150,000. In this case, tile exports have just paid for the inaports, and the trade has paid a fair profit besides the freight; but a balance may be made to appear either against us or in our favor by different naodes of keeping our accounts. If the New York prices of both imports and exports are takeia, it xviii show a balance of $50,000 against us; but if the Emag lish price of both is taken, it xviii show a balance in our favor of $20,000. In the long run, every nations imuports must balance its exports. A temporary balance, settled with coin, is shoxvn at any time by the rate of exchangebut not by Custona House returns. DISTINGUISHED MEcHANIcsOne of the best editors the Westminster Review could ever boast of, and one of the most brilliant xvriters of the passing hour, was an Aberdeen cooper. One of the editors of time London Doily .Joernel was an Elgin baker; perhaps one of time best reporters of the London Times was an Edinburgh weaver; the editor of the Witaess was Hugh Miller, a stone mason. One of the ablest ministers in London xvas a Dun- dee blacksmith, and another xvas a Banff xvatchmaker. The late Dr. Mime, of China, was a lihyne herd boy. The principal of the London Missionary Societys Col- lege at Hong Kong xvas a Huntley saddler; and one of tile best missloimaries that ever went to India xvas a Keith tailor. The leading machinist on the London and Birmingham Railway xvas a Glasgoxv mechanic, and perhaps the very richest iron founder in England xvas a Moray xvorkingman. Sir James Clark, her naa- jesty s physician, xvas a Banff druggist. Josepim Ilume xvas a sailor first, and then a laborer at a naortar and pestle ha Moiatrose. These men, hoavever, spent their leisure hours in acquirinug useful knoxvledge. ExPERIxEa-rs xvmrim W~az Ropz. Some experiments, inaportant to all persons engaged in the manufacture of xvire ropes or xvho may be accustomed to use them, have just been made by Mr. J. Daglish, xvlmo has com- municated the results to time North of Emigland Insti- tute of Mining Engineers. The conclusions arrived at avere, that half the strength of the rope xvas lost by heating the xvire; that the ordinary joint is much iveaker than any other portion of the rope; that if a fiat rope xvas avell spliced it xvas not xveakened thereby, but if the xvorkmanship was bad, it lost from 25 to 33 per cent of its strength. In either event, a round xvire rope spliced became 13 per cent xveaker than before. Round steel xvire rope will bear more than double tho aveight required to break iron avire rope of similar di- ameter. AamJxmNumm AND irs Aaaovs.The metal aluminum is coming more and more into use. A firm at New- castle-on-Tyne, England, have begun the manufacture of it on a large scale, in the pure state and as bronze. Unexpected results have been obtained in experiment- ing with it as an alloy; 20 parts of aluminum xvith SO of copper produce a metal xvhich, to the eye, has all the appearance of gold. Alter the proportions, and mix 10 of aluminum xvitk 90 of copper, and the result is a metal singularly hard, and of excellent application for pivots and bearings in machinery.

MISCELLANEOUS BUSINESS. ]?ooerrrlt a Anti-Frictional JournalThis anti-frictional journal, or box, was submitted to the societ.y for its opinion thereon. The peculiarity of its arran~emerit is, that around a central shaft a cluster of small wheels revolve, each independent of the other, and the inventor claims that by this method there exists no sliding or rubbing point of friction. Wests ]alproIrd ]~IollJ~Mr. Carve introduced this pump to the notice of the association. The inventor claims it is one of the most simple and powerful in use, it is extensively used on railroads, and as a house and cistern pump also for deep wells and (leeks of vessels. The inventor claims that in this pump are combined the double-acting, anti-freezing, lifting and forcing principles. The above articles were referred to the Committee on Scicuce and New Inventions. The late rel)ort of this committee upon the practica- bilitv of Shrimptons High Pressure Condenser, and as published by this journal, was accepted as the sense of the society, without discussion. 1he same committee presented the subjoined report upon ilunkel s Oscillating Piston Engine~ Your committee Ilave carefully examined a neat work- ilig mo(iel of this engine, and have heard and considel-ed the expialiatloils of tile inventor and after taking up his claims, 0110 by one, they have come to tile following coii- cillSiOIlS 3.

That the claini iii relation to the reciprocal motion of the roclcshaft, & c., & c., in our opinion, does not embody any lmecuhial-ity, the same beiiig predicable of any engine. 5. That the claim, relative to the application of modein improveineiits, such as clint-otIs, & c., though coi-rect, is not peculiar to this engine. 13. That there is a peculiar adaptability of tills engilie to steam pumps, fan l)loweI-s, and in general to all kinds of inachilnemy whole a great Velocity is required. Its plinclial alivailtage, however, seelils to consist in its lit- ness fain- I ocoinotives, steaiusilil)s, sd-ow propellers, & c. In addition to the iloilits above euiumerated, the commit- tee have examlimed the balance of foices on the oscillating shalt, antI find it correctly Ilescribed hty the inventor, and that thiei-e is iio extra friction upon tue shaft, the resistaimee hein~ transferred by the steam to the abutuments, and thieiice to the floor or sumlIlloit upon which the eu~ine rests. With regard to conmpau-ative fi-iction, or coiuinam-ath-e cost of fIlch, your coumillittee canntt, as eulgilleers, dive any ulininion, as they have not hall au oh)i)ortliuity of experi- menting with a flihi-sixed engine they, however, do not think that this eiiciume will conipare minlavoi-ably in these particulars with u-eli consti-ucted engines of the ordinary kiusi. By reqinmest, Mr. Lommis Kocim, with the aid of a draw- ing upon the blackboard, deScrii)ed this engine and tite manner of its operation to the seveini nmembers present. 1-fe had seen a large one driven at the i-ate of 2-50 revolutions pem umineite, nnd a small working nms)(hel that could be driven with 01-ics breatim. Tue above meport, being acceptal he in every ilartidn- lar to time association, it elicited rio (hiscussion, but was slnanintoumsly adopted it3 them. Messrs. Warren & Links Low Water Detector wrs iteme inti-stbu-esl. niscussuox. Mr. KoenThe inveiitom-s anti proprietors of this instrlmment hieing present, I should like to Imeam any reasons why the society shioumld not accept the report of tIme committee upon tlmeir detector, to the effect timat it is not reliable. Mm. WAELENIt seems tIme committee have tested an instruiincnt of our manufacture, now in operation in this city, ~uisl they report that no reliance can lie phaced upon it. I have a fact or two in relation to the (leteettil- seems h)y them, which I trust will not me- muama unnoticed. It Imad been tamupered with by the engineer in (-ilarge on several occasions, and at times when expressly fom-Itidden to do so. I contend that the principle upon whichi it is made is a good one, nnd it remains untoucimed by this case. We have fimi- two 3-ears been fully satisfied that the l)ecumliarity of its comistructiomi, and the l)rincilmhe i uvol vod, are such that it can be depended upon. If the instrument seen by thie committee had been left alone and not been mod- died within, as was time case on sevem-al occasions, it u-ouhd not have failed. I do not think that the rehia- bilitv and usefulness of the detector should be thus condeuimned when the only evidence in the case is time isolated one just referred to. All I have ever put on boilers have worked with perfect success, and instances are knowis where tIme water fell but the 1-16th of an inch below the water line when the alarm was given. I hope the society will be pleased to receive furthiem- evidence in the case; we think that we cams offem- such pm-oaf as will materially change the present tisl)ect of it. Mr. BANKSI hiave very recently seen tIme gentleman vhto is proprietor of tise manufactory where the detector in question was seen, and he states as his opinion, that it was placed too highs, and that by droppin0 it a little it would work well. Mr. GARvEYThe fault, as understood by me, is tise rare construction of the gage, that the principle upon whicis it operates is too nice, and that upon trial it would not work as stated. The existence of an error in its construction was very apparent, as when the water was let down below the alarm point the whuistle did not blow until the valve was touched by the point of a knife blade; and, as the committee found upon inspection and experiment that the instrument would not work, they were justified in condemnin0 it. Mr. KoemiThe committee tested the instrument fully. We tried it two different times, and it failed to work in both cases; time fault, as judged by them, was in its construction. A short brass tube, by expansion, operates upon a steel spring, which, in turn, works a valve, n-hen the alarm is given. It is true the brass tube expanded, as claimed for it, but the steel spring failed to perform its duty, and the valve did not n-ark. This is not the only instaisce the members of the comusittee are cogumizant of. Time one at the Cooper Institute did not work at all satisfactoril3; within plemsty of water in time boiler, the steam issued with great force, but the whistle did not blow. 1\Ir. WARRENThe instrument is so constructed that it will blow at any point desirable, and it will also give an alam-m n-linen there is too much water in time boilem- ; this we claim as a very essential point. In melatiomin to time ison-wom-Idag of tIme steel spring upon tIme gage, at time Cooper Institute, I would remark, that at time commencement of our manufacture Nyc were so nisfortunate as to have a large lot of springs burned n-hen being made, which took time life from them. Omie of this lot was put upon the instrument in question, before the fact was discovered by us. Since then, every detector before it leaves our shop is fuihhy tested hay mis, amid tvo years experience has pu-ox-ed to use the principle upon which they work is a com-mect omme. Mr. KocimWith all justice I can call these low water detectors life preservers, for such they are in one respect. The are intended, by wauning us of danger, to save life and property. I repeat what I imave said before, that if one fails to do its duty, be- cause of its construction or principle, we cannot depemid upous any of them. I am prepared to admit ive mnigist visit teim different places xvhere thsey are in opem-ation in this city, and find that they work per- fectly wehh, yet if xve simould extend our visit still furthei- and inspect tIme eleventh, and find it xvhmoliy smmsfit for time purpose inteisdcd could we recommend tIme lustluluent? Might not this very one be the cause of time saci-ifice of valuable li-i-es and property? Mm-. SIMPSONTime questioms should be looked upon by the society in this minsanner, viz Were the cam- mittee examining an instrument in good order, or wei-e they testing omme ivhmich had been tampered with by tie e%ineer in charge, as intimated by Messrs. Warren & Banks. An engilseer m~y, at times, wish to shirk Isis duty, and then xviii alter or regulate an instrumnemit as he pleases. If tunis was tampered xvith, amid its valve screwed up upon sundry occasloIinS in direct violation of orders, can the blame be attached to the construction of the gage, or to its principle, when it fails to act? Was tunis failure attributable to a mechinanical fault, or thinat of the engineer in charge of it? I consider this question an important one. Mi-. BAa-mc~-----Many parties have spoken to me in relation to thie report of our detector, as publishied in the ScuENTIrme AMERIeAN, and they xveu-e, one and all, pomfec-thy astoumuded at its pinurport. We ha-i-c sonse 500 in operatioms, and this is the first that has beems known to fail. Many persons, both in thus city audi in Bostois, husovms to us, place implicit confidence in it among thens are the Manhattan Gas Works, New York city, and the Boston Manufacturing Conspany of tlmat city. We n-ill cheerfully give the committee a list, that they ninay further iusspect and examine our gage, as ve sincerely think they have not seen it as it is. Mr. GxnvzvThe remarks of Mr. Simpson are of thinc highest importance; the conumittee are not reporting upon an instrument that is imperfect. Any tool will give vay under severe usage; omso may tahec a hammer and so batter an instrumeist that it will be perfectly useless, or they may in other ways disarrange it to suiclin an extent that it n-ill be comparativcl3- useless. It is no more than siusple justice to the inventors of this gage, to examine and test timose they consider in good order ; then if their principle is correct let it be so understood. At this period time conmninittee, through its chair- man, asked to be dischsni-ged froisin the further con- sideration of this particular case, which -ivas granted. It was then resolved to appoint a select coisimittee whose duty it will be to experiment still further in relatioins to the reliability of timis dletector. That committee, as appointed by tue chair, is composed of Messrs. Garvey, Holden, and otisers ; the commit- tee to consider the iov nater detector of Messrs. Ashcroft & Co., as named at the l st meeting is Messrs. Merriam, Cameroms, and Garvey. A letter vas received from Mr. Asheroft, n-ho is no-iv in Boston, in relation to Isis imistrument, -ivhichs vas referred to the conumittee, as named above. Time society then adjourned. Spontaneous Decomposition of Chloride of Lime. Time following account of a curious chemical explo- sion is given by Dr. Hoffnsan in the Quuarterhy Journal of the Cisemical Society One niorising, I thinink it vas in the sunsmer of 1858, n-lien entering my laboratory, vhich I mad left hs perfect order am-i the previasus cs-cu- ing, I vas surprised to find the room in the greatest confuision. Broken bottles and fragments of appam-atus lay nboumt, several vindon--panes vere smashed, and all tim tables amid shelves n-crc covered vith a dense la-i-cr of white dust. Time latter vas soon found to be chloride of liuuse, amid fuuriniislmed without dithicuultv tIme explanation of this strange appearance. At the concluision of thie Great Exhibitiems of 1851, M.

SEMI-STEEL Loeoumormvz Tncxs-----We hnave lately ex- amined a piece of semi-steel emnplo3-ed for locomotive tires, manufactured at thine Albany Iron Works, of Corning, Winslow & Co., Troy, N. Y., and its grain indicates great tenacity. We understand that this material has been submitted to a great number of tests to ascertain its teussile streinsgths, and the result has been conclusive as to its being from one-third to one-half stronger than high qualities of Low Moor irons. Some sen-il-steel tires of engine n-hmeels have been in use for six momuths and have given entire sat- isfaction.

HEATING BUILDINGS BY STEAM. In a work of Sir Hugh Platte, published in 1660, steam is suggested for heating a oonservatory, by placing a funnel over a kitchen cauldron employed for boiling the beef for the sturdy yeomen. A pipe from thence was to conduct the steam to the conservatory, during the winter, so as to provide a temperate heat for the flowers. By this mode of artificial heating, he said: If I be not deceived, you may have both oranges, lemony, pomegranates, pepper trees, and such like. THE MARQUIS OF woIfcEsTER. The life of this English nobleman has all the air of a romance. He was the Lord of iRagland Castle, and among the most wealthy and ancient of the feudal families. He was a determined cavalier and command- ed a large body of troops under King Charles I, in the civil wars with the Parliament. In that long struggle the Puritans were the victors, and Bagland Castle was taken, its valuable furnishings carried away, its chief driven into exile, and his estates confiscated. Having come from France to London, in 1656, on some secret mission for the king, he was taken prisoner and coin- mitted to the Tower, where he was kept closely con- fined. It is believed that some birds sing more sweet- ly when confined in small cages, and this may be the reason why we have had some very able works writ- ten in dungeons. While confined a prisoner, Grotius composed his famous work, Dc Veritas, and Bun- yan his incomparable Pilgrims Progress, and so it was similar with the subject of this memoir. His thoughts were first directed to the amazing force of steam, by observing the rising of the lid of a vessel employed for boiling food in the prison, and from this circumstance he projected that machine which has thrown a radiance round his name. Being originally of a mechanical turn of mind, he beguiled the long hours of his weary confinement with mechanical amusements, and after Charles II, was restored to the throne and the Marquis restor~l to liberty, he still continued to find pleasure in making new inventions. He wrote a description of his contrivances, which was published in 1663 and called A Century of the Names and Scantlings of such Irwentions as, at present, I calt to Mind to have Tried and Perfected. No draw- ings accompanied the book, but the annexed figures have been drawn from the following descriptions which he has given, namely, An admirable and for- cible way to drive up water by fire, not drawing or sucking it upwards. 0 0 This method has no bounds, if the vessel be strong enough. One vessel of water rarified by fire driveth up forty of cold water, and a man that attends the work has but to turn two cranks, that one vessel of water being consumed, an- other begins to force and refill with cold water, and so successively. Figures 1 and 2 .represent an apparatus for raising water by steam, which appears to fulfill the conditions of the description; x is a boiler connected to two re- ceivers, a b, by a pipe, s; the steam is admitted or shut off by a cock, e, from each vessel alternately, and l)y a pipe, m, containing two valves opening outwards, from each receiver, they are connected with the educ- tion pipe, i. Another pipe, n u, connects the cistern with the r~ceivers, and the cock at n interrupts the the communication between the cistern and each re- ceiver at plea~ure. By a hole in each receiver, capable of being closed tight, the air may be expelled as it ac cumulates in eithei. When steam is generated in the boiler, x, it ~ows through the pipe, s, and passing into the receiver, a, which has previously been filled with water, it presses upon its surface and forces it through the pipe, m, and up the eduction pipe, i, by which it is conveyed to the required hight and distance. When all the water has been expelled, the attendant turns the cock, e, and the steam flows into the opposite re- s~eiver, b, and at the same time he also turns the cock, .z, and water flows from the cistern to the receiver, a. The steam from the boiler now pressing upon the sur- face of the water in b, forces it up the pipe, i, and when it has expelled all that it contains, the cock, e, again shuts off communication with the boiler and the receiver, b, and the vapor rushes again into a, and forces the water thfit has flowed into it up the pipes, as before related, and so en alternately, while steam rises from the water in tl~e boiler. In Fig. 2, we have another view of the steam en- gine, equally answerable, it is believed, to the descrip- tions in the Century of Inventions. is the the steam boiler; a is the pipe for conducting the steam to U press on the upper side of a piston, e. Its rod is con- nected to a beam which raises the plunger of a pump in another cylinder, as the piston, c, descends. A cock, c, permits of communication with the atmosphere, and another cock opens a passage for the steam under the piston, in the very same manner as a high pressure common steam engine would be worked by hand with- out valve rod connections. Of this engine, the devout marquis said: I call this a semi-omnipotent engine, and do intend that a model thereof shall be buried with me; and his reverend and grateful mind for great inventions led him to thank the Deity with the following prayer which was afterwards found among his manuscripts: Oh! infinitely omnipotent God, whose mercies are fathomless and whose knowledge is immense and in- exhaustible, next to my creation and redemption, I render thee most humble thanks from the very bot- tom of my heart and bowels for thy vouchsafing me (the meanest in understanding) an insight into so great a secret of human nature, beneficial to all mankind, as this, my water-commanding engine. Suffer me not to be puffed up, 0 Lord, by knowing of it and many more rare and unheard of, yea, unparalleled inventions, trials and experiments; but humble my haughty heart by the true knowledge of mine own ig- norant, weak and unworthy nature, prone to all evil. 0 most merciful Father, my Creator, most com- passionating Son, my Redeemer, and holiest of Spirits4 the Sanctifierthree divine persons and one God grant me a further coifturring grace, with fortitude to take hold of thy goodness, to the end, that whatever I do unanimously and courageously to serve my king and country, to disabuse, rectify and convert my un- deserved, yet wilfully incredulous enemies, to reim- burse thankfully my creditors, to remunerate my bene- factors, to reinhearten my distressed family, and with complacence to gratify my suffering and confiding friends, may, void of vanity and self-ends, be only di- rected to thy honor and glory everlasting. In this prayer of the noble inventor his secret thoughts are laid bgfore us, and they impress us with deep respect for the memory of the man. He felt the importance, and had a deep insight into the great value of the invention. The steam engine has done more for the elevation of society than all the edicts of princes. The Marquis of Worcester was not well tre ted by the profligate King Charles II., although he had lost an immense fortune in his cause. He met with ingratitude where he should have found friends, but he was cheered to the last by a most devoted wife. He died in London on the 4th of April, 1667, and his remains were carried to IRagland Castle and interred in the family cemetery, and it is said that the model of his engine was placed beside his coffin. It was stated in late news from England that his grave was request- ed to be opened for examination, to obtain this model. After his death, the Marchiones~s his wife, who seems to have been a congenial spirit and actuated by a share of her husbands enthusiasm, continued her ex- ertions to introduce the water-commanding engine. She was so zealous in her efforts for this object that it was considered unbecoming to her sex and bordering on insanity, and a priest,who had some influence with her, expostulated strongly against her interfering in any manner to dispose of the great machine. We have a very good record left us that the Marquis of Worcesters steam engine had been in actual opera- tion in London about the year 1656. Cosine de Medicis, Grand Duke of Tuscany, who was in England in that year, and had with him a number of letter-writers, who noted down everything which they saw. This diary of the Duke was carefully deposited in the ducal library at Florence. In 1818, this manuscript was first printed, and a very clear and brief account is given in it of a hydraulic machine, invented by the Marquis of Wor- cester, which the Duke saw lifting water, 40 feet high, by the attendance of one man, and which he stated was superior to another hydraulic machine which he also saw, operated by two horses, for raising water from the river to a high wooden tower, to be conveyed thence to the greatest part of the city. It is not stated that it was a steam engine which the Duke saw, but nothing else but a steam engine could have effected such results. It was nothing else than the most stu- pendous water-commanding engine, the semi-omni- potent engine, which the Marquis invented and for which, in the joy and devout thankfulness of his heart, he beseeched Almighty God to make him humble, and for which, when he was laid in the grave, his widow incurred the blame of being considered insane by her priest for persisting in carrying it forward and intro- duce it to the public. When we consider what the steam engine now does, we may well say it was pro- duced by heavenly inspiration. Principle of Giffards Injector. There has been very much analytical discussion, invested with an air of mystery, of the principle of the injector. The principle, however, is perfectly obvious: the light weight, or mass, and high speed of the steam are merged into the greater mass and lower speed of the water; the momentum of the steam thus employed is transformed into and is equivalent to the momentum of the body of water set in motion. True, the steam is condensed in the process; and it is said thus to produce a vacuum, which the water rushes in to occupy, and hence the power of the water to penetrate into the boiler against the pressure within. But it is to be remarked that the vacuum is only incidental to the operationor, more properly, it is not essential to the general principle of action. We do not, of course, mean to imply that the injector, as it is made, may operate inde- pendently of the vacuum; but, properly speaking, there is no vacuum at all, for, if there be a vacuum, in virtue of which, it is supposed, the water rushes in, it is obvious that atmospheric air, with free access to the injector would rush in to supply the void, in preference to the water. Whereas, it is a matter of fact that the injector works, or may he made to work, with the same de~ree of readiness, whether open to, or enclosed from, the external atmosphsere.London Engineer. As this is substantially the same explanation as that which we have already given, we have nothing to say but simply to indorse it. Only, it is to be remarked, that the production of a vacuma, or rather of a partial vacuum, by the condensation of the steam as it comes in contact with the cold water, is the first e(~p in the operation, making room for the steam to rush into, and thus giving it the motion by which it acquires the momentum to carry itself back into the boiler, and the feed-water along with it. GOLD COMING BAcKFor seventeen years past the exchange between England and America was against the latter, but now the tide has turned. Instead of sending gold to Europe, it is now flowing rapidly from thence to New York. The Persia brought no less than $3,100,000 on the 20th nit., to pay for the grain with which America is now feeding the population of the Old World. THE POLYTECHNIC ASSOCIATION OF THE AMERI CAN INSTITUTE. [Reported for the Scientific American.j The Association, having adjourned over, week before last, on account of Thanksgiving, and last week on account of the meeting of the American Institute, met Dcc. 13, at the usual hour, and was called to order by the President, Professor Mason. NEW SUBJEcTS. The PRESIDENT proposed for consideration at some future meeting, The best Economy in Motive Power for Farm Buildings and Small Manufactorics. Mr. JOHNSON proposed the subject of Pottery, upon which Mr. Rouse, a practical manufacturer, of Jersey City, would read a paper. Mr. HASKELL proposed the subject of Drawing from Objects. A practical gentleman in that line would give illustrations upon the blackboard with regard to perspective, elevation, and all ot of drawing. her styles TILE CUTOFF. Mr. ROWELL exhibited a card from the steamer Michigan, received from Mr. Isherwood. There was a full-stroke experiment with a single engine, and an experiment with the engine cutting off at one-third stroke. This experiment showed an advantage of 2 per cent in favor of the full stroke. SEWING MACHINES. The PRESIDENT, upon calling up the special order for the evening, said that the subject of sewing machines was rather out of the usual range of subjects, for two reasons first, it was dealing with something not recently invente(l or brought to light; and, secondly, there seemed to be little strictly scientific inquiry to be made respecting it. The sewing machine has brought up the class of sewing women to a well-defined and proper place in the class of educated laborers. For thirty years the wages of household servants, upon the average, have been above the wages of sewing wolnen. Life was shortened by the labor of sewing women more than in the manufactories in this country or in England. He could remember the time when his mother and his aunts carded and spun and wove their cloth. But the cotton machinery made that uselcss, and it was (uS- continued. Not long ago there was a sewing room in every house, but that is now shut up in the houses of people of prosperous condition. Women having sew- ing machines have ceased to use theln, handing over their work to the class which can do it cheaper. Man- ufacturers have put into the hands of the public more than 200,000 sewing machines, and the call for them is still increasing. They are passing down into lower sta- tions in life. A very small proportion, and that of the coarsest kind of work, can be done by machines driven by steam power. Even in our best conducted manil- factories, such as at Manchester, N. H., there is a Inanifest shortening of the life of the female opera- tives. On tile other hand, it is conceded that the use of the sewing machine is decidedly a healthful occupa- tion. Assuming that three-fifths of full work is done upon all the sewing machines sent into the com- munity, it will give us 300,000 hands employed upon the sewian machine; and if the work produced is five- fold, as all agree, it will be equal to the hard labor of a million and a half of women working with the needle. Mr. STETSON considered the Wilcox & Gibbs machine as the highest point yet renched. He was in favor of simplicity when it could be attained; and it was usually found that progress in an art simplified it. The single-thread sewing machine is generally consid- ered impracticable, because the seam can be ripped out. For family work he regarded facility in ripping out a great desideratum. If we can unite facility of rip- ping out when we desire to do so with security a~ainst ripping out in actual use, it will be the perfection of the sewing machine stitch. In the Wilson & Gibbs ma chine this stitch is peculiar. The PRESIDENTDoes this machine require Howes invention Mr. STETSONNO, sir; but it reqnires many of the improvements upon it. Mr. S. proceeded to explain, by means of drawings, the stitch and its formation. The thread is caught by a hook and carried within the preceding stitch, each loop being twisted before it is thrown off the hook; the result being a twisted loop stitch. The twisting tightens the friction, and in- creases tIle compactness of the job; and the certainty 5 of not looping in two loops, due to a peculiar guard, renders the single-thread sewing machine practically successful. In order that the sewing may progress downward to the lower classes of society, it is ilupor- taut that they should be simple that they may be cheap. He hoped to see the day when the sewing ma- chine would be as common and as cheap as the clocks upon our mantelpieces. Mr. Stetson here exhibited the machine and explained its use. As they ordina- lily run, every stitch is tied; but if the operator, upon stopping tile machine, will then turn it one turn back- ward, the work can then be unravelled. This machine could be lun at a higher rate of speed than any other. The form of the stitch insures elasticity, and the Ina- chine can be worked with perfect success, whether the thread is very tight or vary loose. It requires, there- fore, no particular skill to regulate the tension. Nor is any skill required to fit the needle ; there being a little projecting spur upon one side, so placed that the needle cannot be put in wrong. There is a brake upon the wheel to prevent its being turned backward. These slmplifiCations in the use of the machine will also tend to secure its introduction among the lower classes of sewing women. Mr. LANCEv stated that he had been acquainted with sewing machines for fourteen years. 1-us business was the manufacture of shirts and gentlemens furnishing goods. The first sewing machine practically adapted to that class of work was the Wheeler & Wilson ma- chine. But the stitch was weak, and as the work re- quired a great many bias seams, they were all done by hand. Mr. Lancey then exhibited a drawing of vari- ous kinds of stitchesthe hand back stitch, the hand running stitch, and sewing machine stitches; and also Specimens of work done with the different stitches, to illustrate his remarks upon their relative strength. The twisted loop stitch, in respect to its elasticity, he considered exactly the same as if the loops were not twisted. But, in tills respect, no machine ever nlade would come up to handwork. Upon sewing equal pieces of cloth from the same piece, six inches in length, with thread from the same spool, in the differ- ent ways, he found that the hand back stitch would stretch 11- inches, the Grover & Baker stitch the same, and tile shuttle stitch only five-eighths of an inch, be- fore the thread would break. In the use of thread, the shuttle stitch is the most economical ; but this is no advantage. The PRESIDENTIS this a general rule that the best sewing, whether by hand or machine, uses the most thread? Mr. LANCEvIt must necessarily be so. An estab- lishment in Boston is saving $2,500 a year by using cotton yarn, and the stitch is strong. He would cut every fifth stitch of work done with the Grover & Baker machine, and then guarantee that the seam should hold until the linen should be worn out. It uses about one-fifth more thread than the shuttle stitch; but time is money, and the time saved from the ends being self-fastened more than compensates the cost of the additional thread. In family sewing, the Grover & Baker stitch actually uses no more thread than the shuttle stitchwhat is put into the cloth by the former being wastage in the latter. The Wheeler & Wilson machine, however, is generally used in the Albany district, which is the great collar district, having been introduced there before the Grover & Baker machine was perfected. Mr. DIBBEN stated that the needle was seriously im- perfect in the best machines, being so imperfectly made that when work is dressed they cut the material. Some manufacturers who use the sewing machine Con- sider this such an important evil that they refinish the needles themselves. At the price which is charged for them, the needles ought to be better finished than they are. Mr BABCOCK stated that the exercise of running a sewing machine is undoubtedly wholesome; much more than doing the same amount of sewing by hand labor. If each family possesses a sewing machine, and does its own work only, its influence would be good. But, ln the majority of cases, sewing machines are used as a means of procuring a livelihood; and when a person is obliged to run one for a considerable portion of the time, the labor is excessive, and not beneficial. The power required to run a Wheeler & Wilson ma- chinewhich runs as easily as any of themat the rate of 600 stitches per minute, is about 1-60th of a horse power. This seems small, but it is equivalent to 500 lbs. falling one foot per minute, or a tun and a half ten feet per hour. Place before any woman of ordinary strength the task of raising one tun and a half ten feet per hour, all day long, and it would be considered excessive labor. I do not know a single instance where the constant running of the sewing machine is not detrimental to their health; and I have looked into it pretty closely. There isa demand for some kind of power about sufficient to drive a sewing machinecheap, simple and easily managed. At pre- sent, we have no power that will answer the purpose. A steam engine would be dangerous; the air engino would cost too lunch; electricity is expensive and un- reliable. Springs have been repeatedly suggested, but a spring of sufficient tension to drive a sewing machine five hours would require 1,500 lbs. - of steel, and it would take a man an hour to wind it up. So with weights: it would take a weight of a tun and a half, pulling ten feet per hour; and one man could not pro- bably wind up more than five of them before the first would have run down. If it were not for the friction in applying this power, he could probably drive ten or twelve machines; but the power could not be ap- plied without loss. Mr. HITCHCOCK stated that Mr. Ericsson has invented a machine for such purposes, using compressed air. Mr. LANCEY said that, having used the sewing IRa- chine extensively for seven years in manufacturing, he did not know of an instance where ill effects have fol- lowed from its use within proper hours. In manufac- tories, a great many sewing machines are run by water power, steam power and the Ericsson engine. He would suggest that private families adopt the Doe- sticks methodattaching a cat blindfolded, with a mouse before her, and when the machine was to be run, slip of the hood, and let the cat chase the mouse. (Laughter.) Mr. BARTLETT stated that tile sewing machine was an American invention, and the world was indebted to us for it. Probably the Ilighest price ever paid for a sew- ing machine was that paid by the Emperor Napoleon for the first sewing machine he ever saw. He saw in that machine tile means of clothing the Imperial Guard, which was then a question of great impor~nce to the French government; and he paid 120,000 francs for the machine, and the right to construct others for the use of the government. A GENTLEMAN said that he was a fellow-townsman of Walter Hunt, and, to his certain knowledge, Mr. Hunt invented the sewing machine 30 years ago, but Mr. Howe bought it up. Mr. DIBBEN said that Mr. Hunt made the claim, and presented a model which embodied a similar invention, but that he could not prove his model. He admitted that what he presented was not an original machine, but a machine made after the fashion of something he had done some time ago. The courts gave the inven- tion to Mr. Howe as his right. Mr. Hunt may have had a model made and showed it to others, but he could not prove what it was. The PRESIDENTHas any sewing machine yet ever done work which you deem equal to the best hand- work? Mr. LANCEYNO, sir. I have had in my employ over 400 females at one time, and I do not think that there were 20 of them who luade perfect sewing. Furthermore: of the 400, at least 90 per cent were farnlers wives and daughtersabundantly able to live without the work, but doing it for pin money. - When they lost this work it was no great loss to them, and was an advantage to the poorer class, because there was so lunch work in basting, bands, & e., which the ma- chines could not do, and which the better class did nut care to do. Mr. Woon desired to have half an hour to reply to objections made to the shuttle stitch; but, as the ilour was late, it was voted that the opportunity should be afforded him at the Commencement of the next meet- ing. At the suggestion of the President, it was voted that opportunity should also be offered to Dr. Gardner to speak upon the question of the healthfulness of the occupation. SUBJECT FOR THE NEXT MEETING, The association adopted the subject proposed by the President, modified by him so as to read The best Economy in Motive Power for Farm Buildings, Small Manufactories and Sewing Machines. The meeting then a~ijourned. . - - 6 THE SCIENCE OF COMMON THINGS. NUMUER 1. TIlE eIIEMI~TRY OF KNIVES AND FORKS. Good morning, Charles and John. Good morning, father. I wish you would tell ns what everything on the table is composed of. Do you think that would be interesting Certainly, sir. I like to know what things are made of. Very well. Where shall we begin Why not begin with the table itself? That would seem to be the proper place but I think it better to begin with the knives and forks you will understand why by an(l by. Do you know what substance knives are made of? Iron sir. What (10 you say, Charles Steel, sir 012 iron and steel, I s1ll)l)ose. Yes, iron mid st(el. Do you see this little wrinkled l)lace on th( si(le of the blade near the handle ? Ihat is where the steel blade is weld((l to the iron shaisk. Steel can lie made a great deal harder than iron, and, consequently, when it is ground down to a very thin edge, it does not break away as iron would, so that the blade is made of steel and the shank of iron. Why (10 they not aiike the whole of steel Steel is worth 16 or 17 cents per pound, and iron only 5 or 6 cents, and the manufacturers find it pro- litalde to weld iron shanks to the l)lades in order to save the trifling (lifference in the cost of the material. Ihis is a striking instance of the extreme economy in- tro(luced into industrial operations of the present (lay. What il the difference between iron and steel? Iron is a pure metal, and, like all the metals, it is a simple substance. All the matter of the earth is coml)ose(l of a few simple elements. When I first attended lectures on chemistry, there were 44 of these elements known, but others are being constantly dis- covere(l, and they are now reckoned at 62, of which 47 are metals. How many of these metals do you know Iron, lead, copper, silver and gold. That is five. What is that sheet before the stove? Oh, zinc. And what is that in the therm~~eter? Mercury, that makes seven and brass. No. l3rass is not a simple metal. It is a mixture of copper and zinc. Mixtures of metals are called alloys. There are three more metals besides those which you have named that moe of importancetin, platinum an(l aluminum. Ihe others occur in such small quantities that it is of very little consequence whether you know anything about them or not. You have forgotten steel. No stool is iron with a very little carbon in it. What is carbon? Carbon is omie of the 62 simple elements, and we see it in various formus. The (liauomn(l is pure carbon, crystallized and charcoal is almost pure carbon. How (loes a little carbon make iron so hard Nobody knows. [hat is one of the many mysteries that we meet with in natnre. Indeed, the comI)osition of steel has been a very dilticult thing to ascertain. Ihere is now a discussion going on whether it (loes not (olitain nitrogen in a(blition to the carbon and iron. IhL quantity of carbon, however, has been learned, 01(1 it ranges in (lifferent varieties from 6-10 of one per cent to 1~ per cent. Cast iron, which is still more brittle than stedI, contains more carbon, the propor- tion ranging in the different varieties, from 1 9-10 to 4 310 per cent. I low is iron w(l(le(l to Ste(l lIme emids (if both are heated to a white heat, munch hotter than red heat, when the en(l of one is laid upon the (0(1 of the other, with a little borax sprinkled on them, and they are hammered or swedged together. After the knife is made it has to be tempered. In this l)moce5s it is first hardened as hard as it can be, by hieatiu~ it re(l hot and plunging it into cold water. But 5his makes it so brittle that the edge would crumble right off, amid to make it right for cutlery, a little of this laittleness has to be taken out. This is done by moderately heating it again, drawing the temper, as it is called. What are forks composed of? These forks are composed of German silver, covered on the outside with a very thin coating of pure silver. What is German silver? German silver is an alloy of copper, zinc and nickel, which are mixed in different proportions. The ordinary rule is 60Ths. of copper to 25 of zinc, and 15 of nickel. What is nickel? It i~ one of the simple metals. The new cent is an alloy of 881bs. of copper to 12 of nickel. How is the silver-plating on the forks fastened on? Silver-plating is an art which it would take too long to describe now. The reason why I took knives and forks for the first subject in describing to you the several things on the table, is that the metals are all simple substances. We will begin with the simplest substances and go up to those which are more com- I)lCx this rule will require us to examnine water next week. The Steam Experimnents at Erie, Pa. MEssRs. EDITORS The naval experiments upon the use of steamn on board of the United States steamner Michigan are progressing finely. Although the weather has been at times sufficiently cold to freeze a large por- tion of the harbor, yet where the eddies from the pad- dle wheels circulate there is no ice, owing to to the hot water from the condenser. After runnimmg for a few hours, the first experiment of 72 hours was com- muenced Dec. 1st, at 8 P. M. There being quite a leak in the safety valve, this experiment was entirely re- peated, it proving useful only to get everything into working order, and the men drilled to their respective duties. In this experiment, the engine was run as nearly full stroke as possible 13-l4thsthis being the nearest the valves would allow. The results of this first experimemut were not materially different from the fourth, so that I have not thought it necessary to give it in the following table: Date of commencing Duration of experiment.

It only tended to prove, however, that a himnited steam room caused a greater consump- tion of both water and coal, as a much greater quan- tity of saturated steam was carried over into the cylims- tIer. Although this is no news to the engimleer, yet the experimuemst is of a-ahme, inasmuch as it shows the exact loss. By comuparing experimemst No. 2 with ex- periment No. 4, you will see that the large per centum of gain by cut-offs is all moonshine, and thsat engin- eers and scientific men have, for the last eighty years, subscribed to one of the greatest of fallacies. Why this idea has obtained so long will be quite plain in die discussiomi sure to follow thsese experimnents. I shall not attempt to commemice the argrmment here, btmt confine nmy rensarks to the exlieriments only, amid show the reader that it is iInpossil)le that there can be any error in the ah)Ove results. The Board consists, as your readers are already aware, of four Chief Ehginee~ and one First Aselotant. Mr. Isherwood, as chairman of the Board, stands no watch, but has accepted the much more laborious duty of lay- ing out all tile diagrams and preparing the averaged tables. Eminch of the other members of the Board stands his regular watch of six hours, and keeps a hog of hourly observations, taken svith the nicest possible exactitude. These observations include many other items than those I have thought necessary to place in the above table. The officer in charge takes a diagrans alternately each half hour from both ends of the cyl- inder, marks thereupon the exact time, and files them regularly. These diagrams, with the exception of the variations in the vacuum line by the changes in the barometer, present a singular uniforulity, due, doubt- less, to thse extreme care in firing, the pressure msot varying a pound during any of the experiments. TIme variation in the temperature of the feed water is due to the fact that the tank is filled partly hiy the emsgine and partly by hand; but it will be seen thsat the vari- ation is not great. The temperature of tlme tank is logged when half emptied; the temperature of the hot well is taken from the average during the hour, as is also thse vacuum per the condenser. The boiler pres- sure is as taken from an Allen gage and a siphon, hioth of whlich exactly agree. The coal used in thmese experi- ments is bituminorms, and does miot show so gonil re- stilts per pound as the coal used upon the Atlantic coast. It is perhaps as well to remark that the dia- grams, both of full stroke and cut-off, are exceeding- ly good, the lead on the valve being no muore thmnm is ordinarily given, although, in muy opinion, a trifle too much. In conclusion, allow mne say that every attention is shown to visitors by members of the Board, and I hlope that many of our engineers and engine builders will accept the invitation of the Secretary of the Navy and witness the experimelits that are destined to effect arm entire revolution in marine and stationary emlgimics. Captain Lanman has done everythsing in his power to place visitors at their ease, and every facility is afford- ed them to take notes or examine the logs.

Oregon-Its Climate and Productions---Inviting to Me chanicsWages, & c. Mzssas. EDITORS Presuming that your correspon- dents are not very numerous in this remote corner of tIme republic. I will attempt to note down a few things for the information of your readers. Although this State occumpies suchm an isolated posi- tion, there is, nevertheless, a great maumber of people here who take an interest in the mechanical and social progress of the age. The daily line of stages which has lately been started from Sacranlento to Portland, is atm enterprize which the people of Oregon hail with great satisfaction. The mail is carried with greater speed and safety than it was by the steamll- ship company ; the people being sumpplied mmll along tIme rotmte as thie mail conmes from Califormlia, instead ot beimlg cmtrried liy sea to thme extreme miorthern emkl of the route, aimd then southi again at a ormails pace, neam ly hsalf way back to Sacramnento. Tlmis is a fine healthy coumutry, and there are good opportunities for the prudent and induistrious. All the productiomis of a temllermtte clinmtite do well here. Horses, cattle, & c., can graze all tIme yemtr roumud, there seldom being sufficient snoiv to interfere with pastmmr. hug. There is a good opening here for mechanicssumch as house builders, ldacksmiths, saddlers, tanners, shoe- makers, and all those ismamielmes necessary in a miew commmitry. A pail of commomi coasse shoes for a smiams costs $4, a set of harmiess fronm $85 to $50, connmmon saddles (Spamlish) froni $25 to $40. The Chinese smmgar cane grows well in this valley. There is a great lack of labor on this coast. The great majority of people here are farmers, having usually from a half section to a whole section or more of land, a portion of which they cultivate, besides stock-raising; and where there are so few hands to do so much work, under tIme dis- advantages of a new country, a man must labor veiny hmmrd or make btmt little show. The summers here are delightful, and the winters ~fitilly 5Cd50ll) long and gloomy. There is a constant north wind all summuer, which is a gentle, invigorating breeze, .. brimiging healing upon it0 wings. And, taking a more practical view, it is well adapted to the running of machinery by a win(lnnhl, there being, per- haps, a hundred days that the north wind is as con- stant as a stream of water. In the winter it is from the south, bringing rain, andi always (lense with hu- midity. As I write, the mists are brooding on the hills, which are in their autumnal bloom of the sere and yellow leaf. I have often thought that if it were generally known in the Atlantic States that good industrious laborers could get from $25 to $30 per month here the year round, that it would induce a large number of ener- getic young men to come out to this coast, and operate to the advantage of both borders of the country. Such wages can be obtained here without difficulty. I am aware that hiring out is not the highest ambition of even a poor man; yet, as thousands have to make a beginning from their own unaided labor, the wages here mentioned are a very encouraging indication of what an economical man may do in a few years.

Preserving Meat Under Ground. MEssRs. EDITORS In your paper of Nov. 24, you notice a patent for packing and curing meat in warm climates. I take this occasion to give publicity to a modewhich I suppose is identical with the one above referred tofor curing meats in the hottest climate, and which has been practised in most of the Southern States, not less than fifteen or twenty years at any rate. The plan is to dig a hole in time earth, from four to six feet deep, and lsrge enough for the amount of meat you have to cure ; lay boards on the bottom, and on this pack your meat in saltthe usual quantity anil then cover the hiole with boards and earth, keep- ing it in this condition till the meat is sufficiently salt- ed. By this mode of preserving, no person need lose a pound of meat in the warmest climate Mount Holly, S. t., Dec. 11, 1860. H. CLARK. Artificial Fish Breeding. MEssRs. Euorons:I notice, in your paper of Dec. 8, 1860, an article headed Artificial Fish Breeding. Mr. Kellogg, of Hartford, Conn.,is not the first who has succeeded in this. Mr. Aaron S. Vail, of Smith- town, L. I., one of your subscribers, has been some three years engaged in the propagation of trout, and met with great success. Last year some 25,000 or 30,000 were produced, and the first transported in this country were taken from Mr. Vails waters, and sev- eral ponds were stocked from this successful expeni- memit. This season there is every appearance of an immense increase. A SuBscRIBER. Soap and Civilization. Accoroling to Liebig, the quantity of soap consumed by a nation would be no inaccurate mneasure whereby to estimate its wealth and civilisation. Political econo- mists, indeed, will not give it this rank ; but whether we regard it as joke or earnest, it is not the less true, thiat, of two countries, with ams equal amount of popu- lation, we nmay dieclare with positive certainly, that time wealthiest audi most hmighmly civilised is that which commsumes the greatest weight of soap. This consump- ti(in does oi(it subserve sensual gratification, nor die- pdh1(l upomm fasidon, but upon the feeling of the beauty, conifoirt, and welfare, attendlant upon cleanliness audi a regarol to this feeling is coincident within wealth noel civihisation.

A piece of meteoric iron weighing 2,000 pounds, found in Tucson, Arizona, is about to be sent to time Smithsonion Institute. A smaller piece, found in the same place, imas been used for several years for an anvil in a blacksmiths shop. There are no less than twenty-three steam fire engines in use in the city of Philadelphia, where there are five firms engaged in manufacturing such fire ex- tinguishers, one of which (Neaffie & Levy) lma.s built twenty-seven for companies in other cities. Large quantities of pyroligneous acid are mnanufac- tuned in Philadelphia and sent to Cincinnati for time purpose of curing hams. It gives them time same flavor as those which are sumoked and it may aomswer just as well. M. Auguste Mariette, an eminent French arelmasolo- gist, writes from Egypt that line isas discovered the rensaloms of a large palace, in granite, us the lamnodiate vicinity of the Sphinx. He takes this palace to be that of Cisephrens, who built the great pyraissid. No less than seven statues of this prince have been foioomd in the palace. Time Phoiladelpimia Eooqoiirer states timat the number of oil invells bored on Oil Creek, Pa.,is 345, timat time average product daily of 29 wells is 15 barrels, and that the oil has been sold as low as 10 cents per gallon on the spot. No less than 145 wells have been bored to a considerable depth witimout obtaining oil. Persons are cautioned agaimsst being too enthusiastic about the profitable character of such wells. A simple microscope may be ninade out of a coammon pill box for a few cents. Take out the bottom and put in a piece of window glass; timen paint the inside black, and make a small eye-hole in the lid. In this hole place a single drop of warm Canadian balsam, and allow it to cool. This drop of the transparent resin assumes when cooling, the proper form of a glass lens, with considerable magnifying power. The svood of white thorn is the best known substi- tute for boxwood iii wood engraving. In England, when white thorn of considerable size can be obtained, it bniiogs neariy as high a price as Turkey box.

The subscriber not only receives sixteen pages of valuable reading matter, illustrated by a number of beautifully executed engravings, every week, but at the end of tbe year, if he preserves his numbers (which we counsel every subscriber to do), he will have two beautiful voittmes of fottr hundred and six- teen pages each, witit an index, which will be worth to him, as a work of reference, many times the cost of subscription. The SCIENTIFIC AMERICAN is sold by all the principal newsvenders in the country. Persons residing in cities or large villages can subscribe at the news agents, and receive their papers regularly at the counter of the dealer, instead of by mail, if they prefer it. For terms of subscription, see last page. iHE FUTURE. We have entered upon a new year; and are looking forward, each with his own hopes and anticipations, into the future, all eager to know the events which are to come forth from its infinite depths. But an im- penetrable vail is drawn over them all, with the single exceptton of the motions of the heavenly bodies. While all other sciences are limited to the study of the past and the present, astronomy alone assumes the high prerogative of foretelling the events of futurity; and the most impressive of all proofs of tile power of knowledge is furnished by the l)recision with which her predictions are fulfilled. rite possession of the God-like power of foreknowledge is meving astronom- ers with the sublime ambition of enlarging the sphere of its action, and they are now engaged with two great prol)lems, the soltttion of which will reveal the fate of the itniverse to times more remote than those which have yet been explored by the daring intellect of naan. If it sitall be ascertained that there is a resisting medbtm in witich time planets revolve, the prophecy will be R5 safe as tite foretelling of an eclipse ; because it follows, l)y strict necessity, that all the planets will Win(l spirally inward till they severally crash into the mass of the sun. And, besides the final catastrophe, there is no dottbt that many other events in the future history of the solar system may he foreseen. The other great problem is the motion of the solar system, itself, among the stars. If this motion is in a vast orbit about the common center of gravity of our stellar system, then the questions will arise whether 9 this orbit is very eccentric, and whether, in one of the foci, there is a collection of suns, as the Plelades may be. For in this case, as our solar system approached the perihelion, the temperature might be so increased as to destroy all animal life upon the planets, so that the long work of creation would begin anew. Again occurs the possibility of the motion of our stellar system among its kindred collections of stars. It may be that this is sweeping around some great reser- voir of heat, in an eccentric orbit like that of a comet, and that the matter which composes the solar system will be dissipated into the fiery particles from which it was originally formed as this central heat is ap- proached, and again condensed into a sun and planets as it moves towards its aphelion, away from the heat which scattered it. Geology teaches us that, compared with the lower forms of animals that earliest inhabited the earth, the human race has been in existence but a very brief l)eriod; and when we compare the physical, mental and moral state of the Asiatics, the Africans, and of large numbers of Ettropeans and Americans, with that of Carlisle, Faraday or Agassizthe actual con- dition with the proved possibilities of human nature we are, on this ground, impelled to believe that our race is in its infancy. Have we not, in the history of the past, good grounds to hope that the ignorance, in- temperance, licentiousness, superstition, oppression vice, crime, war and degradation which prevail in the world, will be gradually removed, and that the time will come when every individual will grow up to the full measure of nobleness and worth of whicla our nature is capable? It may be that, when the human species has received its full development, it will be swept away like the extinct species that have preceded it; and as this is the last step in bringing the animal life of the globe to perfedion, it may be that all will perish together; perhaps in that final catastrophe when the elments shall melt with fervent heat, the matter of the solar system shall be scattered into a fiery cloud like that from which it was originally fortned. This matter may then again be drawn together into suns and planets, a new earth like our own may be formed, again to be inhabited by animals rising from the monad, through long gradations, up to man; the human race may again be developed from the savage state to the highest form of civilization, again to over- come the evils of ignorance, superstition and intem- perance, again to invent the steam engine, the micro- scope, the telescope and the electric telegraph, again to unroll the records of the past, and again to speculate on the possibilities of the future. And thus the universe may move through successive cycles of per- petual change forever. FOOD AND GAS REFORMS. England has advanced with rapid strides in educa- tion, rational freedom and wise legislation since the Reform Bill was passed twenty-eight years ago. This is very gratifying to all who labor for social and edu- cational progress. During the last session of Parlia- ment, two bills were enacted which, in an especial manner, affect the welfare of the people, and we look upon them with decided approbation. The one relates to the adulteration of food and drink, and the other to the sale of gas by companies. It has been enacted that any person selling any article of food or drink which, to the knowledge of the seller, contains any mixture injurious to the health of the consumer__also any person who sells for pure an article of food or drink that is adulterated, shall, on conviction before two justices, forfeit a sum not exceeding five pounds, together with the costs of the prosecution, and on a second conviction, the justices may order the particu- lars of the offense to be published. Power is given to local boards to appoint competent chemists, subject to the approval of the Secretary of State, to examine ar- ticles of food offered for sale, alledged to be adultera- ted, and report thereon, but opportunity must be given to the seller of such articles to accompany the pur- chaser to the analyst to secure the article from being tampered with. The purchaser of any article of food or drink can also, upon the payment of a small fee, have the article analyzed by the appointed chemist. Ample provisions are thus made to secure justice to both purchaser and seller. This law is certainly sus- ceptible of wider application and might be copied for New York and others of our own cities with immense advantage to the community. It is calculated to deter unscrttpulous dealers in alimentary substances from adulterating their articles for the purposes of unlawful gain. Provision is also made for cases of appeal, if objections are taken to the analysis of the chemist. This is positively necessary, as it requires not only great chemical knowledge but a very clear judgment to be an exact and sound analyst. The law relating to gas refers only to London, but it is applicable as a guide to other cities. The act de- termines the quality of the common gas to be sup- plied, limits its cost, and provides for a sufficient sup- ply. Its illuminating power must be equal to six sperm candles at six to the pound. The gas made from cannel coal is to be equal in illuminating power to twenty sperm candles. It is to be so pure that it will not discolor turmeric test paper or darken paper im- bued with acetate or carbonate of lead during one minutes exposure to a current issuing at a pressure of five-tenths of an inch of water. The gas company which fails to comply with these conditions is liable to a fine of fifty pounds. The local boards have the power to appoint competent examiners, who, for a small fee, will inspect and report to any consumer on the power and intensity of the gas supplied to him. The cost of gas made from bituminous coal is fixed at 4s.6d. per 1,000 cubic feetthat of cannel coal gas at 7s.6d. This bill is judicious and scientific in its features. There is a very great difference between the quality of gases made from different kinds of coal, whereas most persons suppose that all coal gas is alike. The gas made from common Liverpool coal possesses but little more than half the illuminating power of that obtain- ed from cannel coal. In London its price is about sixty per cent less than the gas sold in New York. No corporation or company has any right to estab- lish an injurious custom or practice. It is the duty of tite legislative authorities to protect the public from such practices, no matter whether it be in the sale of food, drinks, gas, or any other thing. Newtons Lon- don Journal contains a most able article commending the two reform acts we have described. It justly as- serts that while laws had been made previously for the punishment of frauds committed by trustees, bankers, and other persons entrusted with property, it was re- markable that until now no adequate provision had been made to prevent adulteration in the important articles of food and drink, on the quality of which our very lives depend. Well, it is wonderful, but when we know that the telescope was invented before the mi- croscope, we may justly attribute the course of legis- lation to the same causes. Our New Years Dress. Some persons make great pretensions to having arrived at a delectable state of mind in which they remain as unmoved in an old as a new coat. We con- fess to a complete scepticism in the sincerity of all such individuals. We never yet knew a sensible fellow who did not feel a sort of all-averish, good-natured opinion of himself, his tailor, and the rest of mankind, when he donned a well-fitting new coat. ii Its human nature to feel so, as old David Crocket would have said. We look upon the old Diogenesians and stoics, about whom philosophers have boasted so much, as a set of fossilatedeurmudgeons, only fit to be stowed away in Dr. Hitchcocks geological cabinet with the teeth of the great Equns Americanus and the footprints of the Ornithichnites. The SCIENTIFIC AMERICAN, in its own personality, feels an inward warmth of conscious regard, sufficient to defy the most chilling blue-nosed norwester, at being enabled to make his New Years bow to old patrons and new friends in a sprit new dress from top to toe. He considers it the handsomest suit that ever graced his redoubted person; and this anybody can appreciate by a mere side glance, even when running to catch the last train at fifteen seconds and a half behind time. Having discovered the ii elixir of life we intend never to grow old, and our friends, with a full knowledge of this fact, have dressed us up accordingly in the tuost sprightly and engaging manner, and yet with none of the gewgaw and gimp trimmings of the flash style. Our suit is of the best quality, and it is cut in the most harmonious pro- portions to correspond with our character. With such notions about ourselves, we feel greatly energized in commencing our new volume, and with the bestdesires for the welfare of our friends, we wish them all A Happy New Year. 10 THE STEAM EXPERIMENTS AT ERIE. It is not a little remarkable that some old questions of science, which it had been supposed were fixed facts, have been l)ronght lip for discussion by men of science, and others (luring the past year. This has been the case with the working of steam expansively. It had bed recugnized ns a general truth in science and practical mechanics, that in almost every ease a great saving was effected l)y using steam expansively in engines; but it is now contended that, practically, there is no economy in so employing steam. We stated, in a l)revions number, hat experiments were to be ma(le for the determination of this question hy a board of naval engineers at Erie, Pa.; and seine of these (xl)eriments are now given in a communication from Mr. Merriam, on another page. As there presented, the experiments nppear to lie conclusive against the nse of steam expansively, and our correspondent, who was previously, like ourselves, a believer in expansion, confesses to a comlilete conversion in opinion. We have always l)een cautions in receiving an(l adopting opinions, an(l just as tenacious in holding on to them. Prove all things, hold fast that which is good, is a favorite text of ours. We objected to Chief Engineer Isherwoods views respecting the uselessness of cut-offs when his second volume of Engineering Precedents wits published, and until we have more full details of the experiments at Erie, an(l have civen them further investigation, the information we have aequire(l will not lead us to renounce hastily our former opinions on this subject. In the Erie experiments, the amount of coal used pe~ nidicated horse liower, was greater when cutting off at a little over one-third of the stroke than w hen running full pressure for thirteen-fourteenths of the stroke, thus showing a positive loss instead of a gain liy expansion. If a saving of fuel is effected by work- ing steam at full stroke, what an economy in working expenses, an(l what a benefit to manufacturers usin steam engines, will be the result, permitting, as it will, most steam engines to be simplified, as well as greatly retlucing the expenses. But is it possible that the whole engineering world, for the past fifty years, has been laboring under the delusive idea that instead of effecting a saving, a great loss has been incurred in the use of expansive steam? It is quite possible that this may have been the case; but as every pound of steam exhaused from an engine, above atmospheric liresslire, involves the loss of just so much work, we certainly cannot (livble how a saving of fuel can 1)0 effected therel ty in comparison with working steam expansively in tIme best manner, and exhausting it at a lower pressure for the purpose of utilizing all the work in it. We have been giveii to smderstand that the theory adopted to account for the loss entailed liy expansion is the condensation of such a portion of the steam as nullifies all the gain that has hitherto heen awarded to the use of cut-offs. Ilmis theory is scarcely new. In using saturated steam expansively, it has long been held that consi(leral)le condensation resuilte(l there- from ; l)(mt the way to prevent this an(l obtain a great saving has been well known. In the experiments made liy III. him, of Ill ilhmause, France, in 1855, with exixussi ye steam, mud surrounding the my1 inder with a heated jacket, a saving of 28.5 per cent was obtained. hIm. ti onion Mckay, ~if Patterson, N. .J. , also made experiments with a steam ~ncket surrooim(lilmg time cyl intlem, as (leseritmed on page 809, Vol. XIV (01(1 series), of the SCIENTIFIC AMERICAN, by which he obtained a saving of 27 per cent of fuel. 1he refrigerating effect imy exfiausion must be as great with as without a steam jacket, and yet the experimneots were conclusive as to time saving effected by the heated steam jainket. Tlmv, then, does the question now stahl with omim old imiinti ye agent, steam ? Why it is supp(ise(1 that while nmliclI is positively known about it, there is a great deal that is still obscure, and demanding further itcestigatioin to (lear up the entire subject. Working and Molding Butter. Mr. James Lamb Hancock, of Pentonville-road, Lon- don, has patented an improved apparatus for working aimd shaping butter, and for separating it from the bitter-milk, of which lie gives the following descrip- tion My apparatus cmomsi,ts of a jar or vessel, opemi at top and perforated at bottom with circular or other shaped apertires, and with the rim termed with a flange or recess in the inside, with portions of the rim removed. Butter is placed in the vessel, and a piston is inserted in the top thereof; a nut is introduced in the flanged rim, the portions removed admitting of its introduction; a screw is then inserted and turned down through the nut, whereupon the butter is expressed in a divided state through the apertures in the bottom of the vessel. Instead of the nut of the screw being placed inside the flanged uim it may be fitted on the outside of the vessel. Movable perforated plates may be used for the bottom of the vessel The accompanying enguaving us a sectional elevation of an apparatus for working and shaping butter, and for separating it from the buttermilk, fitted in a suit- able frame; a is a jar or vessel, open at bottom, the the upper part of which is formed with a flange, b; c is a piston of or about the size of the interior of the jar, a ; d is a screw-threaded rod connected to the pis- ton, and carrying at its upper part a handle, e ; this rod works through a nut, f; g is a perforated metal plate placed in the bottom of the jar or vessel, a. To use the vessel or jar. for the sake of convenience I place it in a frame, A, provided with handles, i i, the flange, b, rests on a metal plate, k, supporting a flanged rim, i, with part removed as shown in the figure; and the frame, it, with the jar, is then placed on an ordinary tuhi, as for example, one similar to that shown, and the butter to line operated on is put in the vessel, a, and the piston inserted, a cloth having been previously wrappe(l round it ; the handle is then turned, which drives the piston down, and forces the butter out in thin flakes or filaments through the perforated bottom of the vessel, d, into the cold water in the tub, A, where it becomes instantly chilled and freed from all traces of milk and whey. In some cases I perforate the jar or vessel near the bottom, as shown. In the specification of his patent, Mr. Hancock shows a drawing of a frame, in which the jar or vessel is sup- ported at a slight angle from the horizontal line. This apparatus is mmcd for shaping or making up butter into certain quantities, such as pounds or half pounds. A plate is placed in the bottom of the vessel, having a hole formed in it according to the size the butter is required to be made, and the butter which is forced through this hole is received on a slab, where it is cut into the required lengths. The piston and apparatus connected therewith, before described, are used for forcing the butter down the jar through the hole. Butter can be formed into an endless variety of shapes for the table amid garnishing purposes, my altering the shape of thie holes in the plates at thie bottom of tise jar. Alecimaimics Magazine. Recent American Inventions. rhe following inventions are among the most mmseful inihirovemmidilts lately patented: MActuNE FOR wiNBINIm WOOLEN ROVINIiS ON sPOOLS. Time oh~ect of this invention is to facilitate the labor of remuoving the roving from the carder to the ma- ciminery whichi subjects them to the succeeding opera- tion in time manufacture of yarn. The invention con- sists in time employmmiemit or misc of a series of spools connected together or placed on the same shaft, the hattmr heimug placed in a shiinhing frame which is fitted in mu swimiging one, an(l morramiged with certain parts wlmereliy thine rovings, as they are ohisehiarged from the (ar(ler, are woumad upon the spools, the latter being filled consecutively hiny a continuous opematiomi and adjusted automatically. J. A. Chapman, of Poquietanumek, Conn., is time patentee of this invention. SPRING BALANCE FOR SAFETY vALvES. The want of some convenient and expeditious means of reducing the load upon the safety valves of locomo- tives has long Imeen felt. With the spring balance in common use, the nut, constituting the only means by which the load can be varied, requires to be turned so far before any considerable reduction of load is obtained, and the adjustment to effect such reduction is so tedi ous that engineers, when compelled to stop for a time, will often neglect to reduce the load, as it is their duty to do on such occasions, or will fail to reduce it as much as they ought to do. The object of this inven- tion is to enable the load on the valve to be conveni- emitly and instantaneously reduced hmy the engineer as much as may be desirable, amid to this end it consists in a certain mode of employing an eccentric and lever in combination with a spring, whereby the desired result is produced. The credit of this contrivance is due to Charles Graham, of Scranton, Pa. GAS BURNER REGULATORS. This invention consists in a longitudinally adjustable tube having a number of apertures, and so fitted to the interior of a gas burner, or to the pipe or passage lead- ing to the burner, that all the gas admitted to the burner must pass through said tube, amid having its apertures so arranged that, by its lomigitudinal adjust- muent, the gas is allowed to pass through iii greater or less quantity, according as may be required hy time various pressures in different localities. It also con- sists in the employment in combination with the said adjustable tube, of one or more chanibers or dia- phragms, either with or without valves, for the pur- pose of reguulatimig the sup~ily of gas at the varying pressures to which any burmuer is subject. The paten- tee of this invention is William Mallerd, of Fairfield, Comims. Wooden-soled Boots and Shoes --- A New Article of Manufacture. Nothing conduces niore to the health mumid comfort of mu human being than to keep the feet dry and wmumni during time winter mouths. How many poor Imunuan beings are wasting away with pulmonary diseases, who can unerringly date the commenceniemit of their de- climiing health to damp feet. The (lisease of consunip- tion prevails to some extent in most qmmmrters of the globe, buit so fearful are its ravages in this couumitry that it is denominated the great American scouurge. We believe that the protection of the feet from cold and damp is a most irriportant thing to be done to preserve time health, and one of the best means know-n to us to secure dry, warm feet, are the misc of the new and most useful article of wooden-soled boots and shiecs patented by W. C. McClelland, of Chicopee, Mass., on the 6th of March, 1860. Tue boots and shoes made on McClellands plan are unlike the French sabot, which is emitirely of wood, or the ugly Lancashire clog. Time sole is made of hard wood and so treated as to prevent its absorbing moist- umme or being likely to crack. The uppers are made of heather and are secured between the thin wooden in- side and thick wooden outer soles, by pegs, nalis, screws, cement, or any other means most suitable for the kind of article manufactured, and, in appearance, are as neat as heavy boots and shoes made entirely of heather. They are cisiefly intended for farmucrs, miners, fommndrymuen, bleachers, dyers, an(l classes of persomus w-orkimmg in damp sitmuatiomis. As wood is mu good mmmii- conductor, such boots amid slices are sumperior to timose muade entirely of leather for keeping tIme feet warmii, mitsui the soles wihi endure, of comurse, niumcii lomuger, while the cost is mmot so gremut, we are imufommed, as the same qumality comalioseul emitirely of heather.

A well proportioned column of gray marble of the Doric order overhangs the railway at the entrance of the tube on the Anglesey si(ie of the Menal Straits, in England. It was erected in I 8Th to commemorate the military achievements of the Marquis of Anglesey, who was second in conunan(l at Waterloo, and perched as it is on an elevated l)lateau of rock, ami visible for many miles in every (lirection, it has been considered one of the sights of the far famed Menni Straits. To crown this column, the inhabitants of Anglesey have just had a bronze statue (by Noble) of the marquis of that name, erecteil upon it, and the manner in which this stetue, 12 feet 4 inches in bight, has been raised to the top of the column is eonsidere(l a bold and novel, if not an extraordinary feat in engineering The rock on which the column stands presented but an insufficient space for scaffolding, nnd great difficul- ties arose in consequence; these were, however, over- come by the (levice of a youthful engineer named Has- lam, a native of Anglesey, only 23 years of age, and whose untimely (leath, brought about 1)y the anxiety attendant upon the eritic:d operation he undertook, has given additional interest to the 1)01(1 project in question. Ily this (lcsign the expense and incon- venience of the use of scaffolding had been avoidcd. The following is a description of it, taken from the Lomlon Times of November 28 Two balks of tilnl)er, about 70 feet long, were l)laced vertically at the foot of the column, an(l formed a sort of do(ml)le mast, on which was placed what sailors term cap an(l cross-trees, to admit of a tolminast which was lmoisttd imp amd secured imetween the two lower masts the whole atta liming a bight (it 12th feet, giving a clear of 20 feet above time column itself. On the capital of the colunum a shorter mast was erected, aiid betwecim these two nmasts a large pair of traverse beams was lai(l across ; the whole were firmly bolted together and secured with several pairs of shrouds. The strncture looked of so sleimder a nature that wheim the great moass, weighing 2~ timus, whfich was about to be lifted in umi(h-air, to an elevation of 120 feet, was seen, every one felt considerable nmisgiviimgs. The hoisting apparatims commsistc(h of a large hawse carefimlly at- tached to the statue, amid heading throimgh rollers on the traveling truck, along the traverse beams, aimd (lou-n on the opl)osite Si(le of the colnmn, and attachle(l to a heavy three- fold tackle, forumiug time primmeipal purchase. hlesides this, two other tackles, likewise attached to tIme traveler on tIme summit, aimd themmee to the statime, were imsed as supports to time main hoisting alilmaratims. TIme statime coiimimmemmced to move at exactly ii oclock, and rose immajesticaihy in time course of half an Imour to tIme bight of 70 feet, when tIme umalim tackle suddeimly twisted itself up so completely as to al)h)ear like a single rope. This was an awkward moment and appeared to threaten a failure, but time sailors speedily chiumbed imp to time tackle aimd ahih)lieil a lever to time upper hilock, and so untwisted time tackle amminl time hmoistimig was resumneui.

We published the speci- fication of the patent on page 186, Vol. XIV. (Old se- ries) of the ScIENTIFIC AMERICAN, and upon solicitation we gave our opinion on that occasion that the patent was a good one, and that Mr. Young, in a legal sense, was the inventor of the improved process which he claimed. Several correspondents disputed the correct- ness of our opinion, most of them asserting that the invention clainsed by Young avas knoavn before the date of Isis patent. Dr. Antisell. of the Patent Office, edited a avork on oils obtained from coals, which avas published by D. Appleton & Co., of this city, in 1859, in which line took the very same views of this patemat which ave had dope. A long review of this book ap- peared in Silliman s Journal of Arts amid Sdemmcea for July last (1860), by Frank H. Storer, chemist, the object of avhich avas tiac annihilation of Dr. Antisell for his ig- norance regardimag the invention of Young. It avas pnimacipally directed to prove that the patent avas in- valid for the avant of originalitythat the process or inveuation claimed in the pateunt avas old and avell kisown. Under the appearance of much candor, smasart- miess and chemical erudition, the article in Sillimans Jounced was very shalloav, so far as it related to the true nature of thac patent. The present trial has proved conchinsively that the vieavs avhich ue first expressed, and with which Dr. Antisell coincided, have been con- firmued in a very distinguished British Court. At this trial, the svhole chemical science avas rama- sacked for testimony by the defendants, and Drs. Penny mind Playfair, Sir Robert Kane, Dr. Taylor, Mr. D. Campbell, and Mr. Brande, all eminent chemists, were examined as witnesses. Tine ciaarge of the President of the Court on the primaciples of the patemat laws avas very able, and we comnamend time follouing extract from it to all svho are disposed to cavil at the issue of too many patents be- cause they do not (according to their notions) contain a sufficient anaount of novelty: I think a patent may be taken for a new method or an improved method of obtaining a product formerly pro- dmmeed, if the neav or improved method has the etIect~of pro- ducing time old article more economically or in greater quantity. A new or improved method of treating a raav material, so as to give more economicalhy or in greater quantity a product formnserly obtained from the same mate- rial, fails under this rule.

Tiac London (~/ucamicel Niws contains an article on this veiny imuportamat subject by tavo French chemists. rIme value of gmmano amad most other concentrated ma- numres comasists to a considerable extent of the ammonia whicla they contain. As tiaree-quarters of the atunos- Ishenie air consists of nitmogeus, and as inydrogems formsss one-msiuth of all pure avater, if souse cheap means could lie foumad for imaducing tise hydrogen of avater to emater into ciunabination with the nitrogems of air in the form of amniunsommia, this vakiable manuinre could be produmeed in umuhimnited qumamatities, amad the agricultural produmets of tise avorld enormously increased. The production of ammonia at a lou price has been a problem of the Iniglsest imaterest to agi-icumltuirists. It is comnaposed of mi trogeus amnd hydrogemn. Atmmsosphmumie aim is ams imiexhmamustible amad gratamitoums source of imitrogemn. Itowever, this elemniemat Ismesemats so great ama imadificremace in it~ chemical reactiomas, that, notuithistamading tlae maumueroums attemlsts whaicha has-a been made, chemists have not heretofore succeeded in combining it with hydrogen so as to produce ammonia artificially. M. M. Margueritte and De Sourderal, the chemists alluded to, have succeeded in making it arti- ficially from the atmasosphere, by tine use of baryta. The following is the operation In an eartinen retort is calcined, at an elevated and sustained tennperature, a muixture of carbonate of baryta, iron filings in tIme Proportion uf about 30 per cent, tine refuse of conul, tar, amad sawdust. This produces a meductiomi to tlse state of anhaydrous baryta, of the greater part of the carhionate emsaployed. Afterwards is slowly passed a 11 current of air across the poroums mass, the oxygen of avhich is converted into carbonic oxyd by its passage over a column of incandescent charcoal, nvhile its nitrogen, in presence of the chaarcoal and ham-inns transforms itself into cyanogen amsd produces consider- able quantities of cyanide. In effect, the matter sheltered from the air and cooled, and avashined avithn boiling water, gives avith thse salts of iron an abundant precipitate of Prussian blue. The mixture thus cal- cined and cyanuretted is received into a cylinder of either cast or avroumght iron, svlaich serves boths as ama extinguisher and as an apparatus for the transforma- tion of the cyanuret. Thronugha this cyhinde r,ata temperature less than 300~ (Centigrade) is passed a current of steam, which disengnnges, under tlse form of ammonia, all the nitrogen contained in the cyanide of barium. It is inspossible to foresee mill thac results of this great discovery. Among othaer things, it suggests thac production of maitric acid froni the muir by oxydisimag amnmomua. Silvers New Steamship. A maeav steamshaip possessing several maovel featummes laas been projected by Mr. Tlaonaas Silver, of Phailadel- phnia, thae imas-emator of the auclhkmaoavma naarimae govermaor, illustrated oma page 356, Vol. II.

She is to have two paddle engines that are to be located on thae sides amid not in tise cemater as is the case iii all stemmuacas, amad each emagine is to avouk its oun indepemadent shaft amid whacel. She avill also laaae two screav emagimacs, eacha separate amid avorking a propeller under cads quarter. The haumli of thais vessel is to be braced in the masost tinorough muamaner for stremagth ; she is to be dia-ided into fifty avatar-tight conapartusents, and be 15000 tuns burden. Mr. Silver is now in Europe, amid it is stmnted that sea-eral American gentlemanen in Paris have examined his plamas. and are confidemat that sumek a steanser could make a voyage across time Atlamatic in six days. We are of opinion that thae propellers avould ratlaer be an injury than a benefit on sumcha a shalloav steanser. The model of a propeller and a paddle avheel steamer should be quite different; the former does best when it draavs considerable water, the later avhen it is of lighat draft: therefore it is scarcely possible to combine the two primaciples of propulsioma successfully in one vessel.

We continue our extracts from Kin) s work on the Steam Engine, published by F. A. Brady, No. 24 Ann- street, New York: REGARDING THE FIRES WhILE UNDER WAY. Small as this may appear in the eyes of one not practically conversant with the management of the steam engine, it is one of the most important things that the engineer is called upon to regulate; on the one hand, that a proper and uniform supply of steam is maintained, and on the other, that more fuel is not consumed than is actually necessary to produce the re- sult. Different fuels and differently constructed boil- ers re(luire the fires to be re~ulated in a different man- ner, and notwithstanding the repeated efforts, the adoption of specific rules, which shall apply alike to all, is positively absurd. A few general hints, however, touching the leading features, may be useful to those who have not had much experience in this matter hilt they must bear in mind nevertheless, that actual service and observation for themselves, will alone make them proficient, no matter how well they may understand the chemistry of coal, or the natural laws governing the combustion of matter. The proper supply of atmospheric air, and the prop- er time for the combustion, are the important ele- ments in the consumption of coal. A slow rate of combustion, and a moderate draft, always produces a better evaporative result, than when the fires are ur- ged, occasioning them to be more rapid; and hence, on 110 occasion, should blowers~~ be resorted to, if the proper supply of steam can be maintained without them. The fire should be sprea(l uniformly all over the grate 1)ars, and in the use of bituminous coal, should he from 6 to S inches in thickness, bit with anthracite coal, 4 or 5 inches will be thick enough. So long as the ashpit remains bright, there is no necessity for slicing or stirrin~ up the fire, but whenever the spaces between the bars become choked with clinker, or ashes, it will be indicated by the darkness in the ashpit, and, if burning bituminous coal, a slice bar should be run in through the stoke holes or furnace doors to break up the fire and clear out the air spaces. A pick applied from below is also very useful in this respect. In the use of anthracite coal the pick alone should be used ; the breaking up of the surface of such fireas it does not amalgamate or run together, formin0 a crust like the bituminousprevents the regular uni- form combustion by allowing too much air to enter among the disturbed parts of the coal, it requiring considerable time for them again to unite in regular ignition after being once disturbed. It is very impor- tant that no part of the grate bars be left bare, as the admission of cold air, through such space, deadens the fire, an(l cools the flues. It has been ascertained of late, that better results are obtained by admitting air through a number of small holes in the furnace doors, on the plan of W. Wye Williams, Esq., of England. No two furnaces should be fired at the same time; the fresh coal of the one should be fairly ignited before a new supply is added to another, in order to keep a regular supply of steam. Anthracite coal requires less frequent firing than l)ituminous, but with either, the coal should not be thrown upon any particular part of the furnace, l)ut uniformly all over it. Before firing with bituminous coal, it is well to break up the upper crust of the fire, which sometimes amalgamates so closely as to exclude tile proper supply of air. The trouble with most firemen is, that they are disposed to heap their fires too much, particularly in front, some- times half way to the crowns ; this they (10 for three reasons first, because they suppose the larger the fire the greater the supply of steam; second, the more coal there is piled in at one time, the less frequent they will have to fire ; and third, it requires much less labor to shovel the coal into the mouth of the furnace than to supply it uniformly, all over the grates. No coal larger than ones fist should be allowed to enter the furnace, nor in cleaning the fires, should more than one be cleaned at the same time, which should be done at stated intervals, unless it 50 happens, that they all or many of them, have got so dirty that a further sup- ply of coal is useless, when the engine can be throttled off a little while the cleaning is going on. In cleaning anthracite fires, care should be taken not to reduce them too low, otherwise they will take a long time to recover. In cleaning fires, as well as when supplying them, the furnace doors should not be kept open longer than necessary, admitting an undue supply of cold air; and the party, therefore, who, performing his duty as well, does it the quickest, is the best fireman. The slower a steamer runs the greater distance she will perform with the same amount of fuel, provided she has not an adverse tide or head winds to contend with ; with men-of-war, therefore, it often occurs that the saving of fuel is a more important consideration than high speed, and for this reason the consumption of coal is reduced far below what would be required to keep the vessel up to her maximum speed. This can be done in two ways: either by shutting off a por- tion of the furnaces entirely, by shutting the ash pit doors and closing up the cracks around them with wet ashes, or else reducing the quantity of coal consumed in each, by covering the back part of the grates with a thick layer of ashes. When the diminution in the quantity of coal is not very large, this latter plan is the better, by retaining the original heating surface at the same time that the combustion of coal is allowed to go on very slowly, an end very desirable to secure. When, however, the reduction in coal is very consid- erable, some of the furnaces can be shut off, while the back ends of the grates of the remainder can be kept covered with ashes. Men-of-war sometimes proceed at half or less speed, and as a large extent of boiler sur- face occasions considerable loss from radiation, in such cases it will be more economical to shut off some of the boilers and continue with a moderate supply of fuel in the remainder. The furnaces and ash pits of the boil- ers shut off should be closed tightly, to prevent cold air from passing in to cool the surfaces of the other boilers, or, to injure the draft. After a boiler is shut off, the steam should not be allo~ cd to escape, but to remain in it and condense, to freshen the water. PATCHING BOILERS. Inasmuch as all things constructed by human hands are liable to decay, steam boilers are not exempt from this infallible law ; they therefore frequently require to be patched, new stay bolts and braces to be put in, old rivets cut out and replaced with new ones, & c. In patching boilers, wherever the defective part can be reached so as to work at it well, it is best to cut it out and rivet a patch on, calking the seams; but as this cannot always be done, the most common practice is to put a patch over the defective part, securing it with bolts and nuts, or tap bolts, and making the joint with stiff putty, composed of white and red lead, and a small quantity of fine iron borings. A piece of sheet lead fitted over the place to be patched, will answer for the pattern to make the patch by, which, however, before the joint is made, should be fitted snugly to its place while hot. Owing to imperfection in the iron, small cracks are sometimes discovered in the flues or other parts of the boiler subject to a high temperature. Should these not be more than two or three inches in length, they can be stopped by drilling holes and putting in three or four small rivets, hammering the heads well down so as to cover the crack. A leaky stay-bolt, or rivet, has, like the toothache, but one sure remedy, and that one is to cut it out and put in a new one. In cutting out a stay-bolt fitted with a socket, the latter can usilally be saved and retained in its place, ready to receive another bolt; but sometimes a screw bolt is cut out which has to be replaced with a socket l)olt, and as this may be in such part of the boiler which cannot be reached by the arm, or tongs, a very good plan to get the socket in its place is to pass a string through 1)0th holes and secure the ends, drop- ping the centre down and hauling it out through a hand hole ; cut the string in two, pass the ends through the socket, join them to~ether again, and haul the socket to its place. In the fitting of sockets, it is very important that they should be the exact distance be- tween the sheets, with the ends filed square, otherwise the sheets will be drawn out of shape. Application for the Extension of a Patent. 3faum{/acture of Wire CratingHenry Jenkins, of Brooklyn, N. Y., has applied for the extension of a patent granted to him on the 6th of March, 1847, for an improvement in the above-named class of inven- tions. The testimony will close on the 4th of February next; and the petition will he heard at the Patent Office on the 18th of same month. American ArchitectureA Noble Idea. The American Institute of Architects is an associa- tion which belongs to the city of New York and which holds its meetings from time to time, without making much ado about them. At a special meeting of the Institute, held on the evening of the 18th nit., one of the members, Mr. Idletz, read an essay on the .~s- thetics of Architecture, in which he maintained that in everything of practical utility there is a certain adaptedness to its purpose which causes the object to possess something of symmetry and beauty. Here we have a principle in architecture enunciated, and it may be applied not only to architecture but also to en- ~ineering, the construction of machinery of all kinds, and every article adapted for the use of man. Let the idea of Mr. Idletz be accepted as a governing truth in the construction of all things. Every article of utility should combine harmony of form and proportion beauty with usefulness. Some persons seem to be im- hued with the idea that ugliness and utility are twin brothers, and that gracefulness in a machine is a token of its flimsiness. A more mistaken idea never entered the human brain. Let the mechanic, the artizan, and the architect all strive to improve their works in beauty as well as in utility and convenience. Burning of a New Steamer. On the morning of the 18th nit, the fine new steam, ship fames P. King, belonging to Spofford & Tilleston, of Charleston, S. C., took fire while lying at pier No. 4, North river, this city, and was consumed to the water line. This steamer was 1,800 tuns burden, cost $180,000, and was just finished; she was about to take her place in the line to Charleston. Her model was beautiful, and her engines first class. The fire broke out in the engine room, but no person has been able to ascertain accurateiy how it origimiated. Although it took place in broad daylight9, A.M.and two steam fire-engines, together with several hand engines and a number of steam pumps belonging to several of the ferry and tug boats, were early brought to bear on the flames, they were unable to prevent the entire decks and the whole interior wood work and hull from being burned to the waters edge. The engines of the J. P. King, it is believed, may be again fitted up, as they are but slightly injured. The burning of this beautiful new steamer affords evidence of the danger- ous and combustible material used in the construction of a wooden steamer- STEEL FROM CAST AND WROUGHT IRONAn impor- tant invention has been patented by Messrs. Noel & Co., of Paris. It relates to the production or manu- facture of a new metallic alloy, which is easily melted, and when cast forms a species of cast steel capable of being substituted for ordinary steel; and consequent- ly, when used in the construction of machinery, obvi- ating, to a great extent, the use of forgings. The principal bases of this alloy are wrought iron and cast iron, the proportions of which are varied according to the degree of hardness required. To the bases here mentioned are added oxydized iron ore free from sul- phur, manganese, nitrate of potash and chlorhydrate of ammonia. These several ingredients may be used in various combinations and proportions, according to the required degree of hardness of the alloy to be pro- duced. PAPER NEcK-TIES AND COLLARS. Messrs. Smith & Brouwer, of No. 36 Warren-street, this city, have re- cently applied, through the Scientific American Patent Agency, for a patent for paper neck-ties. They are printed in imitation of gingham, silk, & c., and count- erfeit the cloth with wonderful exactness. The whole- sale price is from 25 to 50 cents per dozen! This firm sold, last season, of one single style of cloth neck-ties 17,000 dozen. The introduction of paper neck-ties as a new article of manufacture goes considerably ahead of paper collars, which have been so extensively sold for the past two or three years, and are sold for about the same price. Who will go, in future, without a clean collar and handsome neck-tie of the latest style, when he can purchase both for Six cents.

The unlhnited field which is open to inventors, and the boundless fertility of ideas which is constantly busy in filling this field, are both strikingly illustrated in the invention here represented. In working wood by carpenters and others, a great deal of labor is expend- ed in sawing boards lengthwise ripping them, as it is calledand this work requires not only a true eye and hand, but a certain measure of skill which is the result of long training. By this machine, the operation is performed by any boy, however inexpe- rienced, or any workman, however unskillful. The saw, A, is strained between the ends of the two levers, B B, the opposite ends of these levers being connected by the cross bands, C C, and the straining rods, B. Each lever has its fulcrum on the rocking bar, D D, and the upper cross bar, C, serves as a handle for the workman, by moving which up and down he operates the machine, giving motion to the saw. The stuff rests upon the roller, F, by the rota- tion of which it is fed along to the saw the roller re- ceiving motion from the lower rocking bar, III, through the intervention of the rod and ratchet wheel, as shown. The weight, G, rests upon the stuff to hold it down, while the guide, H, keeps it in place as it slides along. The advantages of this machine are thus stated by the inventor: It can be manipulated to good ad- vantage in shops where woodwork is carried on to any extent, where steam or water power has not been in- troduced, for ripping up plank and boards into differ- ent widths. One man will do as much work on one of these machines as three will with the ordinary hand saw in the same time, and the work is not nearly so laborious. It is self-feeding, and gages the width as it saws, and always leaves a square edge on the stnff which needs very little dressing afterwt~r~ with the plane. It occupies but a very sifiall space in a shop 8x6 feet. In ripping long stuff, there should be two trusselsone before and one behind the machinewith rollers to carry along the stuff. It cannot easily get out of order, can be worked by any person who is not a mechanic; even a boy fifteen years old will operate it. Lastly, the price brings it within reach of every mechanic who has a shop. The patent for this invention was granted, through the Scientific American Patent Agency, on Dec. 11, 1860; and further information in relation to it may he obtained by addressing the inventor, D. B. BarthoL omew, at Lancaster, Pa. Since the above description of Mr. Bartholomews Sawing Machine was in type, we received the an- nexed letter from the inventor, which we take the liberty of appending: MEssRs. MURN & Co.This morning I came into possession of my Letters Patent for the Hand-sawing Ma- chine, for which you will please accept my thanks. You have been very successful in prosecuting my case before the Patent Office, and bringing it to a satisfactory termina- tion by giving me ingenious claims that are not likely to be nvaded. Your ingenuity and skill in executing drawings and drawing up specifications is a model piece of work, in my judgment, not to be equalled by any other attorneys in the country. I feel proud in saying that we have such an institution as Muna & Co.s Patent Agency, through whom inventors can always receive justice at the Patent Office. This is the second patent I have received through your agency. Should I be so fortunate in the future as to invent anything worthy of a patent, I shall procure your services in preference to any other. I re main, yours truly D. B. BAErHOLOMEw.

A cord, b, is fastened with one end to the top of the lower sash, and the other end to the middle of the up- per sash at one time, this cord passing over a hanging pulley, c. The pulley, c, is supported by a cord, d, which passes over the fixed pulleys, g and e, and is joined to the cord, d, which supports the hanging pul- ley, c, similar to the pulley, c, but on the opposite side of the window. The cord, 6, which passes over the pulley, c, is similar to the cord, 6, and is fastened to the sashes in the same manner, but on the opposite side. The cord, d, supports in its bight the pulley, f, so that, by drawing down this pulley, both ends of the cord, d, are raised, carrying up the two hanging pul- leys, c and c, to which they are fastened. To the pul- ley, f, is attached the cord, i, which passes down and around the spool, k. Now, to raise the lower sash the spool, k, is turned to draw down the pulley, f; while turning the spool in the opposite direction lowers the upper sash. A ratchet and pawl hold the spool from turning back to drop the upper sash, which, of course, tends to fall by its own weight. A cord, i, is fastened to the pawi to draw it away from the ratchet when the upper sash is to be lowered. By leaving the pawl in the ratchet, so as to hold the hanging pulleys stationary, and taking hold of the lower sash, the window may be opened at the top and bottom at the same time; the upper sash falling just as much as the lower one rises. It will be seen that the middle stop between the sashes must extend upward only about half the hight of the upper sash, in order not to interfere with the movements of the pulleys. Application for a patent for this ingenious invention has been made through the Scientific American Patent Agency, and further information in relation to it may be obtained by addressing the inventor, H. T. Stanard, Wayne, Mich. SOME samples of very fine Persian cotton have lately been received in Belgium from Trebisonde, which have been found well adapted for making lace. SCIENTIFIC_AMERICAN.

C A JOURNAL OF PRACTICAL INFORMATION IN ART, SCiENCE, MECHANICS, AGRICULTURE, ChEMISTRY, AND MANUFACTURES. VOL. IV.---NO. 2. NEW YORK, JANUARY 12, 1861. NEW SERIES. Improved Rice Mill. Fig. 1 is a porspective view of the machine; Fig. 2 lice has been called the universal food of man, is a vertical section Fig. 3 is a view of the revolving and with much propriety, as it is more generally used attrition screw, with refrigerating scoops on it~ shaft, as an article of diet than any other vegetable product. and Fig. 4 is a perspective view of the screw hub in an Some very interesting statistics respecting the rice crop of various coun- tries, and the modes of using it, will be found on the succeeding page.] As rice is mostly the product of tropical and intertropi cal countries, nature has provided the kernel of it with a very tenacious coat of husks, which afford it protection against the attacks of various insects that abound in those re- gions. These coatings also serve the benign l)U~l)O5~ of preventing the rice from becoming unduly heated when transported (lry in bulk to distant countries. It is, therefore, now gener- ally shipped in husk, but, in order to prepare it for marketable plirl)08e5, the husk or coating has first to be remove(l frem the clean, beautiful kernels or grains. The mechanism which has hitherto been usually employed is very ru(le, an(l far from being efficient for the purpose. In its rough state, rice is called paddy, and the coarse outer husks are removed by careful rubbing between stones which leave the inner coat or cuticle still adhering with great tenacity, and its removal requiring very peculiar modes of operation. It is custonsary to do this by a beetling process, pestles hem0 elevated and allowed to drop successively into the rice, which is (leposited in a mortar, until the cuticle is separated. This process is very slow, and involves much waste by breaking the grains. Experience has demonstrated that the best way to remove the inner cuticle of rice is by attrition or the rubbing of the grains against one another. By this process, however, the rice is liable to become so heated by the friction generated by the rapid movement of the kernels against one another as to become quite brittle, in which condition much of it is liable to be broken ; thus greatly diminishing its marketable value, besides no inconsiderable portion of it is carried off in the chaff. The improved rice cleaning machine represented by the accompanying engravings is entirely different in its construction and operation from the rice beetling ma- chines; it operates upon the rice by attrition, through the instrumentality of a revolving section screw and a fh~ring lamb, amimle provision being made for keeping the rice from becoming overheated by introducing cold water between the inner and outer casings of the pct, so that the operation may be performed rapidly, and the scouring of the rice effected in a superior manner, with very little waste, as may be inferred from the fol- lowing description of the machine. inverted position, to show the minute channels on its under edge to admit air in from below to the center of the mass. Similar letters refer to like parts on all the figures. A represents a strong frame for supporting the mechanism; B is a metal oblong pot of an egg- shape, which contains the rice. It is formed with double sides, having a water space, L, between them for the purpose of receiving a stream of water to keep the pot and contents cool. The bottom, b, is secured by a hinge to the pot at one side, and held by a suita- ble lever catch, r, at the other. A nozzle IRis in- serted into the center of the bottom for air to pass freely up into the mass ; a is a vertical shaft mounted in suitable bearings in the frame, and extending down through the center of the pot to its bottom; C is a hub secured upon its lower part. There are three sec- tional screw blades, c c c, secured on the hub, and it is of a trumpet or flaring shape. On its under edge are a series of narrow air channels, c, inclined in a direction contrary to the rotation of the shaft. The hub rotates close to the bottom of the pot, and neither rice nor chaff can 0et under it. (~peretien. - The p ot being filled with the rice, the shaft, a, is set in mo- tion and made to rotate rapidly. The rice is sub- jected to a complete rub- bing and scouring action, and a constant circulation of all the grains is carried on from the top down at the center, and upward at the sides. It is drawn into the center, and passes through the spaces be- tween the blades, c, and is rubbed between them and the smooth bottom; thence it is forced outward toward the circumference, and is driven upward to the top along the sides. By this mode of attrition, the inner cuticle of the rice is rapidly removed and a complete scouring action effected, so as to produce beautiful, clean and smooth kernels. It will be ob- served that, by the curvature or flare of the hub and smooth bottom of the pot, the circulation of the rice and the effectual rubbing of the grains upon one an- other are secured. A very great pressure is exerted by the superincumbent column of rice upon the bottom and yet it is evident that a complete circulation, with a powerful rubbing action, are combined in the opera- tion. When this operation is effected, the shaft is stopped, and the bottom opened by unfastening the catch, r, as shown by the dotted lines, when the rice drops below into a receptacle provided for it. This mode of cooling the pot will generally be suffi- cient, but as some kinds of ricesuch as that of Cuba and the Indiesare more difficult to clean than that of South Carolina, it may be sometimes necessary to drive the mill with a very high velocity, thus causing increased friction and heat among the grains of rice. Other refrigerating appliances are also represented, which may be employed or thrown out of gear by a clutch on shaft, a, according to circumstances. These appliances consist of an arrangement for carrying up the rice regularly while being rubbed, and exposing it to the air to cool; then conveying it down again in a stream to the center of the pot, so as to secure a complete cooling and attrition circulation at the same KASES IMPROVED RICE MILL. 18 tune.

With tIme machine in proper oroler, millions of stitches mnight lie made without ilmo~s~sing i)iie lint if it is omit of oroler, a stitch may be obropped occasiomdly. If it is, the shuttle stitch is merely ma(le of diumble lengths, limit the chain stitch is left so tlmt it may be raveleol 50) that it is isecessary ~vith the chain stitch to booik river the work anol tack down every lililce where a stitch is ulro~)ped. An ol~ection to the Grover & Baker stitch is, that it forms a riobre upon the cloth which cams lie irosneol itt. With this stitch alsoin, if a stitch is olroppeil, the work may lie raveled froimn that hiuuimmt. the ans(iummmt of thmead omse(l us so mimehi greater t.lmt, in so single large factory, the difference may amoumnt to $200 a lay. For the clothing required in the ITiuiteil States there would hie a differ once of $40,000,000 in the article of thread alone. As to the elasticity of the stitch, if prisperly seweol, it is equal to the elasticity of the cloth hut the stitch may be seweil so as not to lie 8(1 elastic. In tIme specimens of work which were exhibiteil time othur evening, the stitches were mnasle to bireak, as Pinihars razors were made to sell. us actual use, the seam is never exposed to the straimo to which that work sewed oin a hinias was subjected. Again, if tIme stitch is so elastic one way it mnuist lie the other, so i05 to cause a gaping of time seam. For this reason, a great elasticity is an evil rather than an nolvantage. Mi-.

In the experience of four yeas-s with the Grover & Baker stitch, I have never known of its either wear- immg or being ironed off when properly made. TIme PRESIDENT (interposing) inquired of Mrs. B (time Itody present referred to by Mr. Wood) whether the stitch could be so construmeteol by a good seamstress i05 noit to break. Mrs. B The Wheeler & Wilson stitch? Yes, sir. TIme PREsmuiNTIf it is true that, with the several macimines, a skillful hand managing the thread can make a seam that will not rip or break, it seems to me thsat that covers the whole ground. Mr. LAxsFxeI think not. Yosm can get operators to work well with almost any machine. Bust when you come riown to the practical wants of the family, there are few who can olo it. What the pumblic want is a machine, simple, easy and natural in its operations, so thmat they cannot hmelp making a good stitch. For that reasrin, time Grover & Baker stitch is superior to the shuttle stitch it cannot go astray. Bust time tension c:mn lie puirpossely mtorle so tight as to cormugmote the woim-k, aisri then, if it is upon a buns, it may be easily liroken. With the shuttle stitch, thse cloth must be seweol in a stietelmerl condition, to gain that elasticity. Time PREsIDENTIs it as true of hand woik as of ma- chine work timat but few can do it well Mr. LANsiNGYes, sir; more tlsan of machine work; for if the machine is in order, an ordinary hand can make good work; bust good hand sewing requires years of exl)erience. Mr. L. commented upon the ammuoumut rif thsremmd usseol, stating that tise difference had been greatly over-estimated; for, in fiumily work, no more threaol was consumed with the Grover & Baker than with the Wheeler & Wilson machine, because the amommnt wasted in fastening off the work and from the ends made in rewinding with the latter, is equal to the excess used in the stitch of time former. The stitch hieimmg self-fastening, it is unnecessary either to fasten off time ends of the seammus om- to ttock dowim stitches which issay lie rlroppeol. Mr. Woou resumed Isis icimmarks. Thse tissse required us rewinding the tlmmead for the Wheeler & Wilson usacltimme is but five minutes a day. The lower spool of tIme Gm-over & lItoker machine must be replaced about as oinften tins the bobbin of the Wlmeeler & Wilson must lie filled; tummol replacing the lower spool, re-threading tIme lower crooked needle, would take as much time as filling tIme liobbin. Mr. GARS-EY suggested that so far as time thread is stretcheol in the tension which imbeds it in the cloth its eluosticity is reducerl. Mrs. B (in reply to olumestions asked by the presi- olent) stated thitot she had usserl all three kinols of stitchscs; Isad worked umpon sewing machines for five yeas-s Imaving used the lock stitch nearly three years and the Grover & Baker stitels for two years for all kinds of fainihy sewingumpon cotton, sihk, woolen, flannel, & c. She Imad not worked upon anything as heavy as heaver cloth, bust had worlred upon cloth Iseavier than thoat used for a gentlemans coat. With either the lock stitch or time Grover & Baker stitch, a well in- strumeted person can do good work that will not break. Titere is a greater tendency in the Grover & Baker machine to drop stitches. It is almost impossible to ruin the machine more than one rir two months without its dropping stitelmes; and tisen there is a tendency to rmovel. The olserator osight to notice it when it begins to drop stitches, limit it is very difficuilt to get her to notice it. A girl with the Wheeler & Wilson machine can olo more ann luetter work in a day than with the Grover & Baker machine. Machine sewing is neater tonni strongem-, and thmerefore prefes-red by customers to hanoi work. Hand work is not now done so well as it was hiefore the introdusetion of the sewing machine, for there is less attention paid to it. All kinds of sewing for time family can be done by the machine, excepting ~ustting on buttons and making button holes. Girls who Istod beconme so umnlsealthy that they were com- pehled to give ump Imand sewing had mused time machine for several years withmout injury. Time machine does not requmire so musels stooping as hand work, anol requmires less application of the eyes. - She had used the umacimimme 18 lmousrs out osf the 24 withomst being so tired as mu sewing five hours by hand. The time spent in threading the lower needle of the Grover & Baker ma- chine, passing the thread through three or fosur loops, is much more than in winding the under thread upon the bobbin of the Wheeler & Wihson machine. Dr. GARDNER stated the result of extensive investi- gations he made for the last two or tlsree years uspon the influence of the sewing nuachine, in a hygienic point of view. In economy of woirln, the sewing ma- chine is a great boon to mankind; but if, as soume Isave thought, it kills one woman in ten, or maims one woman in five, or makes womrmen sickly and feelule, it is a Isad machine. Professional men have sometimes said that the working of the sewing maclsine pro(lusceol rheummatisma of the knees. This mwht lue if theme was a predisposition to it ; especially when the operator is beginning to learn, when she exerts strength enough to drive five or six sewing machines. One lady said it pro- duced neusralgia; but uspon covering the treadle so a.s to prevent the cold from affecting her feet, the nemuralgia ceased. Others have asserted that it tends to produsce or to aggravate the class of diseases known as female diseases. He had made extensive inqusiries to ascem-taims whether this assertion had any fousudation hi fact. At one place he found that they had introdusced compressed air to drive the machine. They were Singer machsines, doing heavy work. They had fosmnd no bad effect frnins driving the machines without the aid of power ; bust the work was so Isaud that the gim-Is huad not the strength requsisite to nlrive the machines fast enouglm to pay. To get up a paying speed it was necessary to introduce power. Yet, while these girls were driving these machines as fast. as they cousid, no suds diseases were produceol. On the contrary, the universal testi- mony of the large manufacturers was that the working of the maclsines benefited the lmealth of the operatives. To explain this, it is only necessary to consider tIme general physiological law, that use strengthens and the want of use enfeebles. Not only are the particumlar muscles in use strengthened by the exercise, limit the adjacent mussehes. Thuss the blacksmith not only strengthens his arm by his labor, but his elsest is en- larged; the pectoral muscles are strengthened. In one of these large establishments, employing 100 girls, the average daily absence fi-om all causes was but three so that it could not be that femuahe diseases are ordimi- arily either caused or aggravateol by the use of the sewing machine. On the contrary, line Isad come to the conclusion that it would be a valuable curative agent in many cases. In the Europeami water cure establish- ments, the great remedies are air and exercise, walking up mountains and down declivities. And in Sweden, thsere is a new pathiy, called the movement cure. He had no doubt that the prescription of a sewing machine would be better than that of a great many of the pills now 0iven in many cases of debility. Another objec- tion to the sewing machine was that it led to the injusry to the retina called Aniaurosis. There is this temidency in hand sewing, from the constant apphi~ation of the eyes requmired, especially in fine, siice work; but upon the sewing machine thse work is co niecluanical, and the required action of the eye so gemiemal, that, sunless there is a predisposition to Amaurosis, the use of time sewing umachine woumld not cause that disease. He had coms- suslted every distinguisheri ocushist in the northem-mi States, and the uniform reply corresponded to this con- chusion. Nor is there, as is sometimes im~gineol, lint flying about in the use of the sewing machine to irmj mmmc the eyes. After a prolonged examination of five om- six months, lie had come to the conclusion tisat the sewing machine was the greatest blessing to the comusumnity, in a mere hygienic point of view, that ever was given. Mr. Youzo feared that women wosuld be obhiged to work as masiy hnsusrs in the olay tni ennui the sanse amommnt of food and clothing with the sewing machimme that they formerly olid with the needle. The PRESIDENT staterl that it had been ascem-tained in England, by a censuss taloen in a certaimi disti-ict embrar-- ing all classes of seciety, that the average length of womans life is jiust in proportion to tIme asnomunt sIte has to do ; being the longest where no servammt is kept. decreasing with those keeping one servant, nusol ole- creasing with each additional servant On the con- trary, the life of men is longest when huelonging to tlte class of professional men, merchants, & c. Fime pht~-si- cians, upon consultation, ascribed it to thme fact that women do not take vigorniuss pxercise in the open air, and that the work whichs compels them to usse thmeir hamids and feet tends to suspply time want. The smubject for next sneeting will be the Feonomny of Motive Power for Farms, Buildings, Suisall Manufac- tories and Sewing Machines.

For measuring the quantity of electricity developed by the voltaic circle, an instrument was invented by Mr. Fara(lay; but before describing it, we shall allude briefly to the principle upon which its operation is based. When the electrodes are tipped with platinum, and immersed in dilute sulphuric acid, the water con- tained in it is decomposed into its elementsoxygen and hydrogenand the quantity of these gases is al- ways in (lirect Proportion to the amount of electricity which has 1)assed it. Upon this principle, an instru- ment called the voltameter, is con- structe(l. There are several forms of the - voltaineter, one of which is represented in the cut. A represents a glass jar contain- ing the dilute acid, and inverted over a __ trough containing the same fluid. B B K are the two platinum electrodes. The jar J is usually graduated into cubic inches and -~ tenths of an inch. If a certain battery gives off a definite amount ot gas per minute in the voltameter, and an- other produces twice as much in the same period, then the second battery is twice as powerful as the first, as far as quantity is concerned. This instrument is not a good measurer of the intensity of the current. Pro- fessor Daniell found that a battery of ten alternations produced in a given time nearly as much of the gases as one consisting of seventy alternations of the same size(l battery. This shows that time instrument should be used with certain precautions, and its indications should not be too implicitly relied upon for, although it measures all the electricity which passes through it, yet a current might not have the power to decompose water very energetically, and yet be able to produce powerful magnetic ciThets. The surest way of ascer- taining the power of any voltaic arrangement is by actual exl)eriment with regard to time application which is to be made of it. When a strong current, either of intensity or quan- tity, is caused to pass through a fine iron or platinum wire, the wire will be heated to a red heat, and some- times will fuse. Advantage is taken of this fact in sub- marine l)lasting and in gas lighting, as well as in some delicate surgical operations. For l)n)ducing this heating effect, if the circuit to be traversed is short, a current of quantity may be used; but if it is long and irregu- lar, as in the lighting of a large building, a current of intensity is better. The science of telegraphy, as far as it relates to inland lines a~d their working, has attained a degree of perfection ; but the art of successfully operating the submarine telegraphespecially where it occurs in long linesis,, as yet, in its infancy. This was made painfully evident by the failure of the Atlantic Cable; and if Americami inventors do not deserve any of the (liscredit of its failure, they have not, as yet, brought forward a better cable. The chief defect of the Atlantic Cable seems to have been the faulty insulation of the conducting core; and this (lefect appears to have been due to the selection of ~utta-percha as the insulating material. This sub- stance is a very good insulator while solid, but it softens and melts at a heat considerably below that of boiling water, and a number of miles of the cable were ruined by the heat of the sun while lying in the yard of the manufactory. Although gutta-percha is very plastic while warm, yet at common temperatures it is as inflexible and toughs as the stiffest sole leather, al- though much more easily cut when spread over a hard surface. To the other defects of gutta-percha must be added its comparative inelasticity, and, when broken, it snaps (lireetly off, like so much hemp. What, then, must be the effect of a tensile strain which is greater than the strength of the gutta-percha, but not sufficient to rup- ture the outside covering of iron? Some portions of the cable, which have been taken up from deep water, have been found to have the wires of the outside covering (Irawn nearly straight; thus involving an enormous strain upon the gutta-percha interior, and, as much of the cable now laid must be in this condi- tion, it is I)robable that defects exist all along the line. The Atlantic Cable, however, does not seem to work well even in shallow water, for two trials were made of it in one of our inland riversthe Mississippiand in both cases it stopped working in a few days from the time of its laying. A plan has recently been patented by Mr. Hughes, in which the insulating material is to be of such a nature as to maintain a semi-fluid condition until it comes in contact with water, when it is to immediate- ly become solid. A cable constructed upon this plan would fill all its own leaksa great desideratum to be gained; but we are not yet aware that there is any substance which will answer that purpose. The Effect of Steam Navigation on Commerce. We are indebted to Messrs. Baileys, Davis & Co, Coin- mission Merchants of Rio Janeiro, Brazil, for the fol- lowing extract from a recent debate in the Chamber of Deputies of Brazil. Senor Franco de Almeida said: That the Honorable Deputies may appreciate the immensely valuable interests which steam communica- tion must create and increase, let it suffice to enumerate some of the principal products of which North Amen- ca stands in need, and those which Brazil requires. We would furnish sugar, honey, drugs, fruits, coffee, cotton, tobacco, rice, hides, cocoa, sarsaparilla, preci- ous woods, precious stones, dyestuffs, tapioca, cloves, isinglass, saffron, gum, copal, vanilla, copaiva, broom reed, ~pmassava), crude metals, & c., & c. North America could not find a nearer market than Brazil, nor could she procure these productions with greater facility or so cheaply ; Rio de Janeiro would necessarily becomue a great Amnenican depot. On the other hand, we could supply ourselves with the productions of the United States with greater advantage and at a much cheaper rate. We would import wheat, flour, meats, butter, lar(l, horses, machinery, all articles of hardxvare, im- plements of trade and agriculture, furniture, woolen, and cottoncloths, sailing vessels, steamers, and further- more, all the imitative works ef art, which in the United States are extraordimmrily cheap compared with Europe. To convince the minds of honorable deputies, I will remind them of a fact. The commerce of England with us from 1840 to 1850, was nearly always station- ary, averaging 2,000,000 sterling, according to the Blue Book and MeCulloch; during that samne period our commerce with the United States was greater. And why? Because there was no steam communica- tion then between the empire and Great Britain; the American clippers had an advantage over English barks; binmt the honorable deputies xviii remark that as soon as a line of English steamners was established, these wonderful results were produced. The insportation from Brazil, into England in 1853, three years after the inauguration of the line, increased 150 per cent, over that of 1848. In 1855 it had increased 300 per cent; England, which in 1852 imported 3,000,000 pounds of coffee, imported in 1853, 52,000,000 pounds; in 1854, 59,000,000, land in 1855, 112,000,000. A Nzw DIscovERy IN WINE MAKINGA new discovery made by a wine grower near Bordeaux, France, has just been made public, and has somewhat startled the old and steady wine factors, makers, and doctors of that place. The discoverer of the natural phenomenon by which wines are rendered at once fit for bottling, without the long probation they have hitherto been made to undergo has been for some years living in the mountains. In the various qualities of wine grown by himn he was struck with the difference of develop- ment of maturity which took place, according to the temuperature of the cellar in which the barrels were stored. The higher up the niountain the sooner did time wine arrive at perfection. The reason of this dif- ference soon became clearatmospheric pressure di- mninishes gradually as the region rises above the level of the sea. This discovery induced the experiment of raising and diminishing at will the atmospheric pres- sure upon the barrels and with the most perfect suc- cess, it is said, so as to make old wine in as many days as it formerly took months. DEATH OF AN EDITORWe learn that Mr. Alexander Mann, formerly editor of the Rochester (N. Y.) Ameri- can, afterwards of the Albany Statesman, and subse- quently engaged on the New York Times, and first editor of the Railway Review, died suddenly of apo- plexy, on the 6th nit., at St. Augustine, Florida, to which place he had removed on account of his health, and had intended to make it his future house. He was an able political writer, and his geniality of disposi- tion and integrity gained him a host of warm friends. Coating Iron with Zinc. By Malletts English process, iron is coated with zinc as folloxvs :First immerse the iron to be coated in a cleansing bath forused of equal parts of hydro- chloric and sulphuric acids in xvarm water. The taste of this bath should be quite sourabout a pint of acid to five gallons of water is sufficient. The metal is scrubbed with sand and emery, to remove the oxyd and render the surface perfectly clean. It is then washed in soft xvater and insmersed in the preparing bath, which is made of a saturated solution of hydrochlo- rate of zinc and sulphate of ammonia, from which it is transferred to the metallic bath. This is composed of 202 parts, by weight, of mercury and 1,292 parts of zinc, and to every tun weight of this amalgam one pound of sodium is added. Any less quantity than a tun may be melted, according to the amount of work to be done. This amalgam is melted in a cast iron vessel, and the prepared metal is dipped into it. As sooms as the iron has attained a temssperature of 6S0~ Fah. in this bath it is removed, because if it is contin- ued longer it xviii be eaten into holes. Great watch- fulness must be exercised in dipping the iron, so as not to allow of its being dissolved, as the affinity of the amal0am for the iron at 680~ is very great. Small articles of iron may be galvanized without the aid of quicksilver, by cleansiimg them well as described, dipping them in a stromsg solution of salammoniac timen transferring themn at once ~o a bath of molten zinc containing some pieces of salammoniac and some ground glass placed upon time surface. By this method of zincing iron its surface is liable to be rough, but by runnimsg it between rollers or hammering it on a plan- ishing anvil, it can be nsade quite smooth. By using a bath of hydrochloride of tims (tin dissolved in unuria- tic acid), as a substitute for the preparatory bath of sal- ammoniac, a rather superior coat of zinc will be ob- tained. OINTMENT FOR TILE SKIN. That able xvriter, Dr. Erasmus Wilson, on cutaneous diseases, says : The beuzoated oxyd of zinc ointment, properly prepared, is the most perfect local application for all chsronic in- flammations of the skims that is knowms. It is cleanly and agreeable, and imas a tendency to concrete upon the skin and form an artificial cuticle to an irritated and broken surface. This ointment is made by selecting the best and most fragrant guma benzoin in tears; this, when commuinuted, is added to good fresh lard, in the proportion of ten grains to the ounce, an(l the whole digested in a water bath for about forty-eight hours; this, subsequently strained, is mixed thoroughly with ten grains of the xvhite oxyd of zinc. Guns benjamims is now very generally used in ointments by London apothecaries for preventing their deconsposition; ten grains added to an ounce of lard effect this object. It has an agreeable odor and nsay be used as a substitute for gum benzoin. 1)vzsxe MoTnEn-oF-PEARLBlack mother-of-pearl, which is so much used for buttons, may be dyed from time white material in the following mamsner When the mother-of-pearl is cut out into buttons, they are steeped for twelve hours in a strong solution of nitrate of silver, contained in a glass vessel of a blue color to prevemit decomposition by the light. They are then allowed to drain, and washed several times in distilled water, after which they are placed in chloride of so- dium, in which they remain for an hour and a half. They are then washed in rain water, drained and washed over with a very weak solution of nitrate of silver, and exposed to the rays of the sun for several hours. Ammoniacal solutions of chloride of silver and of nitrate of silver may also be used for the pur- pose of dyeing this simbstance black ; but the effects of these salts are less satisfactory. CLARIFIED GALLThe Druggist, published in Cincin- nati, contains the following recipe : Ox gall is pre- pared for the use of artists in the following manner: To one pint of fresh ox gall, boiled and skimmed, add one ounce of finely powdered alum; leave it on the fire till the aluni is dissolved, then let it cool, put it into a bottle, and cork it loosely. Treat another pint in the same way, with one ounce of salt, instead of alum. After standing more than three months, care- fully decant from each bottle the clear portion, and mix them together. The coloring niatter is precipi- tated, and a clear, colorless liquid is obtained by fil- tration. It is used for mixin,, artists colors, and to prepare ivory, oiled paper, & c., to receive the colors. ROMANCE OF THE STEAM ENGINE. ARTICLE V. IIAUTEFECILLE. In the middle of the seventeenth century, Jean Hautefenille, the son of a l)aker in Orleans, France gave great i11(lications of mechanical g~ius, when a boy, and the Duchess (le Bouillon, having heard of this, sent for and took him into her family, where he l)ecame a great favorite and received an excellent edu- cation, lie l)ecalne one of the most celcbratc(l me- chanics of that age, although he had adopted the Church as his regular profession. In 1678, lie pro- pounded several novel applications of heat as a moving power, and suggeste(l the employment of the val)or of alcohol instead of water. He proposed that it should he evaporated and act as the motive agent, then he con(lensed in a close vessel and used over and over again for the same purpose. He also proposed ignited charges of gunpowder for the l)uipose of nioving ma- chinery, as a substitute for steam. I-Ic also descrihed how a motive engine could he coristructe(l to operate a piston hy using the vapor of water and a vacuum al- ternately in a cylinder. The alcohol engine was simi- lar in its nature to the ether engine lately in use in France, and the gunpowder engine has been frequently proposed in our own day. PAPINTiTE SAFETY VALVE. One of the most ingenious mechanics that ever lived was Dr. Denys Papin, of France. He (liscovered the mode of reducing hones to a pulp by inclosing them in a tight vessel aii(l suhmnitting them to the ac- tion of high pressure steam. He came from Paris to Lon(lon amid published an account of his invention in 1781. The pumping of the water from the mines in England being then a subject of unusual interest, he proposed to operate the l)li~P5 hy compressed air, and to convey it from a considerable distance for this pur- pose. For example, where there was a mine distant about a mile from a water wheel, he proposed that two cylinders containing pistons should be placed at the wheel, and two other cylinders at the minethe whole to be connected hy a pipe. The pistons at the wheel were to force compressed air to work the pistons at the mine, and these were to operate the lifting pumps and draw imp the water. This plan was correct in theory, bit when tried it failed of success. Although the reason of the failure is miot given, we hehieve it was eause(l through (lefective aml leaky pipes. For several years a eolnpresse(h air engine has been in use in a coal mine near Glasgoxv, Scotland, an(l although the air is forced through a pipe one mile long, no difficulty has been experienced in working it. Papin did not receiv~~e patronage due to his genius in England, and he was worse treated in France, his native land, for, being a protestant, he was exiled by the revocation of the edict of Nantes, when lie mufter- wards went to Marpumrg, in Germany. When residing there, he applied his comuipresse(l mmii machinery to (irain mu mine, but it mulso failed, mis it had (lone in En~- land; then he tried time converse system, l)y exhuaumst- ing the tube, l)umt this fmuiled mulso; an(l we are confi(lent that it must have heen through leaks in the pipes. Papin was ahout two centuries ahead of his age in the employment of compressed and exhaust muir machinery. Both of his plans have been used with more or less success for railways, within the past twenty years; and the employment of compressed air to (Irive raihroa(l cars and sewing machines is frequently discussed with great plaumsibihity, as feasible methods, at time present (lay. Papin also proposed the hot air and vapor engine il- lustrated by time accompanying Fig. 1, for pumping mines ; c is a cylinder, in which there is a tightly-fit- ting piston, d, with a ~)aeking ring on it; a is a grate with a flue on it, muid 4 shows how tIme heat passes into the cylinder, having a small (Iraft pipe, ,f. The stem of the piston goes throumgh the cover of the cylinder; n is a lever turning on a hinge, and is fastened on the top; a spring acts to press it into a notch in the piston rod, when it comes above the covem. A small pipe, e, inserted through the cover of the cylinder and also through the j)lstoii, is firmly chose(l at time upper en(l. The stopper (if the pipe being taken omit, the piston is easily moved to the bottom, when a small qumantity of water is huassed down under the piston and the pipe is closed. The heat from the fire soon con- verts the water into vapor and the piston is forced up to the top, where it is held by time notch of the lever. The fire was then withdrawn, the cylinder cooled, and a vacuum was produced under the piston which then descended by the pressure of the atmosphere. The lever, n, was then withdrawn from the notch, to permit it to descend. Fig. 3 shows how a vibratory motion may be given by the up-and-down movement of the piston, e, through the rack, b, on the piston rod and the pinion, a. This steam and vacumium engine is umn doumhutedly impracticable, but it is certainly very similar to hot air engines in the mode of generating the vapor by admitting a single charge of water for every stroke. There is no danger of explosions by this method. The crowning feat of Denys Papin was his invention of the safety valve illustrated by Fig. 2. A small tumbe, e, is fitted into an opening, a, in the cover of a boiler, and in this is placed a valve ground to exactly suit the orifice. A rod is pumt into an iron staple, r, at one end; its other end is kept down by the weight, o, which is hung nearer to or further from the valve, to resist the pressure within, as may be desired, in the same manner, said Papin, as a weight is hung upon the Roman balance or steelyard. This invention is employed upon every steam boiler at the present day. It was devised for Papins bone digester, but no boiler whatever would be safe without it. THE MAGNESIUM LIGHT-- A NEW FIELD FOR INVENTION. Not many months since, Chevalier Bunsen drew pub- lic attention to the researches which he had made with magnesium as a source of light. This metal readily takes fire in the flame of a common spirit lamp, and gives out a most brilliant light. Compared with an ordinary candle, a wire of magnesium, only 0.0117 of an inch in diameter, produced as much light, according to Bunsen, as 74 sperm candles, at the rate of five to the pound. In order to support this light for one minute, a piece of wire 39 inches long, weighing 1.85 grains, was required. About 2~ ounces of magnesium therefore, woul(l be required in order to maintain a light for ten hours equmal to 74 stearine candles, con- summing 320 ounces of stearine. Magnesium wire is made by forcing the metal through a hot steel die, by means of a steel piston. Bunsens arrangement for bumming the wire was made by connecting spools of it with rollers moved by clockwork, so that the wire should be unrolled like the ribbon of paper in Morses telegraph; the end of the wire thus gradually pushed forward passed into the flame of an ordinary alcohol lamp, where it took fire. It is evident that a magnesian lamp of this sort must be more simple than any of the existing arrangements of the electrical or of Drum- monds light, for lighthouses, & c. Where an extra- ordinary amount of light is needed it could readily be produced by burning large wires, or several thin ones at the same time. The photographical effect of the magnesian light is said to be unrivalled by any other artificial flame, and with it photographic artists may be able to take pie- tumres buy night nearly as well as by daylight. The present high price of the metal magnesiuma, however, precludes its uise for common purposes, but could it b)e obtained at a moderate cost, miniature suns might b)e used for illumination in every house with common spirit lamps and a winding off arrangement of the 21 wire, which would cost but a few shillings. Here is a new field for chemical experiment; magnesian forma- tions are numerous in America, and economical pro- cesses may be discovered for the reduction of the metal from its ores. A few years since, the metal alumi- num was almost unknown, and its price was higher than that of gold, but now it has become compara- tively cheap, owing to the improvements which have been made in tIme chemical processes for treating aluminous earths. It will undoubtedly be the same with magnesium, and in a few yemrs, and perhaps months, we should not be surprised if the magnesian light would take the place of gas, coal oil, sperm candles, or any of the illuminating materials used in our houses. Sanitary Science. In New York there is a Sanitary Association, but although its objects are benevolent and deserve the support of all classes, we believe it has as yet been unable to effect much good. A meeting of its mem- bers was held at the Home for the Friendless on the evening of the 27th nIt., at which a resolu- tion was passed recommending the formation of a female sanitary missionary association for the city. On the occasion, several speeches were made. Dr. Harris spoke particularly of the importance of a pub- lic knowledge of the practical science of ventilation, light, economy and correctness in the formation of personal habits. The Rev. H. W. Bellows stated that there was great difficulty in gaining popular at- tention to sanitary reform, as it was a question involv- ing many details. There was an unwillingness on the part of those who considered themselves very chari- table persons, to stoop to the real work which charity requires. Hygiene is almost as little understood by the higher as by the lower classes. Rooms were not well ventilated and ladies clothing was not worn in accordance with the laws of health. James T. Brady, Esq., spoke of the defective styles of public houses. He stated that there were no cities in Europe where the places of refreshment were kept under ground, as in American cities. Several speakers, such as Dr. Muhlenberg and Dr. Griscom, gave it as their deliberate opinioum that most of the degradation of the lower classes was directly traceable to evil habits, such as the drinking of ardent spirits and the chewing of tobacco. Edwin Chadwick, Esq., of London, recently deliv- ered an address on this subject, in which he stated that in several districts known to him, by a proper drain- age within the houses and the use of water led into them by pipes, the death rate had been reduced one-third annually. He said I know one instance, in an agri- cultural district, and with laborers alone, where the death rate has been reduced to less than one-half, and within twelve in a thousand. From common lodging- houses, tIme enforcement, through the police, of sani- tary regulations, typhus and diarrhea, as epidemics (whilst prevalent among the houses of the laboring classes), are banished. In our well-regulated district institutions for pauper children, those epidemic visit- ations which ravage the children of the families of working men, are almost unknown, and the death rate is reduced to one-third that prevailing amongst their children. The death rate among British soldiers used to be 17.5 per 1,000 annually; now, by sanitary re- forms, it is reduced to 4.7 per 1,000. The city of Liverpool, in England, used to be one of the most sickly in the world, but owing to the scientific sanitary measures which have been carried out in it during the last few years it has become one of the most healthy. During the past ten years there has been a reduction of 30 per cent in the mortality bills. This, certainly, is a very important subject, and yet it is very difficult to excite the public mind to give it proper attention. STEAM FIRE ENGINEThe Portland Co. in Portland, Maine, are now building five steam fire engines, of J. B. Johnsons patent, viz: one of the largest class for Portland, two of the third-class for New York, and one second-class for Philadelphia. The third-class are light engines weighing only 3,100 pounds, and having very large wheels are drawn by hand more rapidly than a first-class car hand tub. The engine built for the United States Co., Philadelphia, third-class, has play- ed at one fire no less than five hours consecutively without stopping. 22 Reply of Professor Silliman to Mr. Jos. W. Spragues Inquiry, What is Momentum l MEssus. EDITORS -In the issue of your journal for Dcc. 15, 1860, Mr. Sprague has propounded an inquiry under the above head, an(l has seen fit to employ a section from the first edition of my Natural Philos- ophy to show that the (lefinition of Momentum there given is wroflg I all wrong, from l)eginniug to end. As Mr. Sprague proposes to follow up the subject in your issue 0 f this week, I have waited for his conclud- lug article but, as it has not appeared, I have to re- quest you to 11l11)iish my reply to this writers confident denunciation. Some confusion (loubtiess exists, even in high au- thorities, in the (listinctions to be observed bet~veen lnomodum and ni viva. I think, however, there is no reason why this subject should not be made plain and ns it is one in which all mechanics feel an interest, you will perhaps confer a furor on your readers by publish- ing the following paragraphs from the second edition of my Natural Philosophy. Jloueidein.1he momentum of a moving body is its amount of motion, or its tendency to continue in mo- tion. The momentum of a body is equal to its mass multiplied by its velocity. When a force acts upon a holly free to move, it produces its efbict as soon as 1110- til)Il is (litlused among all tile molecules, and the force is thci transferred into the substance of the moving body. In consequence of the inertia of matter, if the moving body should meet no resistance, it would con- tinue to move with the same velocity. an(l in the same direction, forever. ihe expression Mv rellresents the intensity of the force which ha5 set the body in motion, and 31l~ rep- resents the munount of force that is at any time accu- mulated and retained by the inertia of the moving body. In either case, the moving body is supposed to encounter no resistance from any other object.0 When a luovilIg 110(1 encoiniters resistance, depend- ing not olIly 1111(111 inertia, but also upon other ploper ties of ]natter, the effects l)roduced depend upon tile rnl)idi ty with which the force, expressed by momen- tumn, is ilrought to act upon the opposing i)ody. This clasi of efibets are, tiler fore, proportioned to momnen- tum lflioltiplied by velocity. This product H f2 is called ni Vi VII, tile application of which, to practical mechanics, will lIe explained hereafter. By the pnin- (iple that action amid reaction are equal, we know that when a mnusket is discharged tile force of the explosion reacts upon the musket with the same intensity as it projects the bali. According to the principles of mo- lllelitllm, the weight of the gmni, multiplied by tile ye- locity (If tile recoil, must be equal to the weight of the bali, multiplied ily till velocity of its projection yet tile reellil of tile gun is received by the sl)oltsIllan with perfect impunity, while the uloving ball deals death or (lestructioll to opposing objects. ISi Vile, 01 Livilly ibnce, is tile power of a mnovmn~ body to overcome resistance, or the measure of work which can be performed before the body is brougilt to a state of rest. The vim viva of a body is represented by 31 Vt, ~ the mass of tile body multiplied by the square of its velocity. Wileml n body is projected verticlilly upward, tile hight to which it will ascend is proportional to the 51111mm of its velocity. If W represent the weight of time body, and h the hight to wIlicil it is elevated by a given imupulse, tIme amnoumit of work performed will be represemmte{l by Wh, but }V=lfg and hY2 2g, sub- mititutiilg these values of W and h, we have the work l)erfornled=~ NFl. Hence, the work which can be performed by the accumulated power of a moving body is equal to one-half the mass multiplied hythe velocity.~ lake time case of a pile-driver, in which a heavy mass of iron is elevated to a hight of 30 or 40 feet, and is then suddemlly allowed to fall the resistailce over- come in raising the driver is exactly proportional to the elevation to which it is raised, and the accumulated power of the stroke increases in the same ratio: hence it is evident that the ~i viva, or power of overcoming resistance, must be truly represented by NFl. Again: in the case of a railway train moving with a velocity F, the greatest velocity attainable by a given power of steam; let v be the acceleration of velocity imparted to the train by the locomotive during the first second of its action, amid 31 the mass of the meviug train. micllldilmg the ilCOmlll)tive. If the move- ment of the train were not retarded by friction, or some other opposing force, we should have V=nt, or the velocity, v; would go on constantly increasing i)imt such we know is not the case, for the train soon attains a maximiumm velocity, when the emitire force of tue loeomiiotive is every instant expended in overcom- ulg frictioll, amid the train mnoves omi with a ilinunemitum expressed by 3fF, but its vis vine is expressed by MV2.t If the force of steamn were sud- denly discontinued, the power of the moving train to ascend a grade, to overcome any obstacle, or to deal destructiomi to itself, or to any object with whiclm it comnes imi collisiomi, would still be proportional to vis ella or 31V2. Now, suppose tlle velocity of the train to l)e doubled. so that V9 V It is evident that in any given interval of time the train will pass over twice as many points of resistance as before, amid, as it passes each point at twice the previous velocity, it will encounter at every point twice as much resistamice to mu(ltion mis before. Hence, to impart to the traimi a doumble velocity, a fourfold force is required ; and the poiver of the train to overcome resistance will be pro- portiomial to its vis viva, MV2. This will be the true measure of the force which has imparted the velocity V, and which is now constantly expended in over- comiiimlg the resistance encountered by the moving trmiin. The same primiciples deterimmimme the power expend- e(I or work actimally l)erforuie(I, resistamice included, by ally kind of umachimiery. It may be necessary to explaimi lmll)re fully the dis- timiction between llloIllvllllllll and (25 Vi VII, 50 that it may be readily umiderstood when time omie or the other is to be taken as tIme measure of force. Momentuni, MV, expresses the relation of force to inertia, or the amnount of niotion in a mnoving body. Vis ViVIl, NV?, is the measure of twice the amoumit of work which a moving body can performn before it is brought to rest. Vis viva is the nmeasure of force re- qmmired to mimaintain a comistamlt umotiomi, NV, against tlme resistance caused by the positive properties of bodies, as attraction, cohesion and repimlsion. Momentum is tile niensiure of the force required, without regard to timne, to set a body imi motion with a velocity, V wimemi no otller body interferes with its Iliotion, as in time ease of a body falling freely in a vacuumll. Imi the case of the railway train, the mass of the traimi, lilultiphed by its velocity, is the nleasure of vIseflIl work perforuied imi a unit of time, but it is not tIme measure of resistance overcome, or actual work performed, or of the force which ilas been expemided in performing timat work. The latter is mneasured by one-hmdf the (is vim, or 3112. lUast rations of Vis VivaSuppose a batterimmg 111111, weighing 4,000 lbs., to be impelled witlm a velocity of 30 feet per second, its vis viva, 31V2=4,000x 30x 30 ~3,600,000; yet a cannon ball weighing 64 lbs., fly- ing with a velocity of 1,000 feet per second, will have a power of dealing destruction more than sevemmteen tinies as great, for its nis viva equals 64,000,000 lbs. Calculations of this sort explain the origin of the ter- ribly destructive power of the engines of modern war- fare. A railway train movimig 50 miles an hour will pos- sess more than six times the vis viva that it would have when going 20 miles an hour; and, therefore, it will possess more than six times the power of dealing de- struction, either to itself or to an obstacle, at time for- mer than at the latter rate. Thus, the well-kmiowmm relatiomi between speed amid amount of (lamage, iii case of accident, is readily aecoumited for, as also the enor- nious comparative cost of fuel and wear and teumi of trains of high speed. Time destructive power of hurricanes, which mnove from 60 to 100 miles an hour, is readily understood when we know that the power of dealing destruction increases in proportion to the sqimare of the velocity. I might add further illustratiolls on this subject, but I feel confidemit flint mm careful study of these extracts will satisfy all who xxiii take the trormblc to examuine the subject, that there is more in it tlman Mr. Spnagme has yet clearly comprehended, and that it will meqimire more than his triumphant denial to disprove it.

The kinds and qualities of coals are so varied that 110 gemseral rules cami be given for their selection, but there is otie poitit, hoivever, which we think will not lie dispitted, asid that one is, whenever there is a choice, the omily sore h)han is to select the hiest for, fhsoimghs its first cost may hi a little more, it ivill hirove to lie thse elseapest in the etid.

Yet this is it thsing of (haily uccurretsee. Bit, regardh esS of the money view, there are other disad- vaistages attetidimig the use of the inferior coal. From the fact of there licimig niore burned, the firemeis have more to supply to the furnaces, titid it requires, on their part, greater care and attention to keep the fires in goid order thus imposimig extra duty on a portion of thin ship s crew whose energies are usually overtaxed.

It gives employment to many thousands in almost every section of the country, and a very large capital is invested in the machinery used for the several operations connected with it. Staves must be obtained folT all the l)arrels and hogsheads made at home; besides, we export most of the staves require(l for making hogsheads in England. These facts will at once render apparent the importance of any improvement, however small, that may be made in any of the machines used for riving or splitting staves from the rough blocks. The accom- panying engraving is a perspec- tive view of an improved machine for cutting out the staves from bolts. There arc various kinds of stave cutters. This one belongs to that class in which a reciprocating knife is used and made to give a curvili- near cut, passing through the bolt of wood, until it comes (Iowa against the bed plate or the feed table which holds the bolt. The objects of the im- provements are to preserve the cdgc of the knife from becoming dull by pressing against the feed plate; also providing a roller, set in elastic bearings in the knife gate, to afford a yielding pressure against the staves to prevent them from splintering while being cut. In the figure the framework is represented as formcd of timber, but it is de signed to construct such machines of iron, and they will be very compact and strong. A represents the two sides which constitute the framing of the machine. B is a feed table extending across the framing. The bolts are placed upon it and fed into the cutter. C C are two short steel axes on which the cutter gate is hung and swings. A plate of metal is secured in a recess on the feed table along its front edge, so as to present a firm bed to the cutter. This bed would soon render the edge of the knife dull by its coming (lown frequently against it. To obviate this evil, strips of compressed india-rubber, D, are laid over the metal plate, so that, when the cutter descends through the block and cuts out a stave, it comes against a firm, instead of a hard suhstance. E is the swing gate of the knife. Its two knives are hung hy the axes, C C, to the side supports. F is an under cross bar which unites the sides of the gate at the foot. G is the cutter head, consisting of a hroad plate extending across the gate. H is the knife or cutter which extends across the gate, and is secured in a plate on the inner side of the head, G. Another plate, I, on the gate, extends across the frame. It has a series of rib ~uides secured to it, which pass up and down in guide recesses, J J, formed by adjusting pieces fastened on the front edge of the table, B, in advance of the strip, D, which can he compressed in its recess by the screws represented. ZR is a roller secured in recesses formed in the sides of the knife gate. It is situated behind the knife and opposite its lower edge. The axes of this roller have elastic spring blocks, a, of india-rubber, or other suit- able substance, set in the recesses of the sides of the gate, and S S are screws for adjusting these, so as to set the roller ~ proper relationship with the cutter. Tbe compressed rubber prevents the knife from cutting it. The gate is now shown as raised to cut, and a bolt of wood supposed to be placed on the feed table, B. It is pushed forward so tbat the thickness of the stave to be cut is regulated by the guide ribs. Tbe gate now (lescends, and the knife, Ii, cuts through the bolt, (Ic scribing part of a circle in its descent ; and when it comes against the strip, I), the cut stave falls (Iowa from the bolt. The soft nature of the india-rubber strip, D, prevents the cutting ed~e of the knife from becoming (lull by coming in contact with the hard bed under it, and at the same time it gives a firm bed to the downward action of the cutter. The spring bear- ings of the roller, I, admit of a graduated resisting pressure on the staves, which tends to prevent them from splintering, and thus a greater number of sound ~tayes are produced than would otherwise be obtained. The stave machine is the invention of Mr. W.

Most of pressed clothes are guided into the basket.

It will also be observed that the pressure of the rolls upon the clothes operates to make the lower ends of the standards hug fast to the sides of the tub, so as to keep them in position. The partial dryin~ of clothes by this simple and convenient apparatus can be performed far more rapidly and with greater ease than by the common method of wringing. It is a labor-saving machine, adapted for use in all families, and it ___ appears to us that, while it saves labor, its action will not tend to wear and tear linen like that DOANES IMPROVED STAVE MACHINE. of wringing.

To render labor more light and pleasant should be the aim of every inventor, and this is the design of the clothes- wringing machine represented by the accompanying engraving. Ike object of it is to press the water out of washed clothes and obviate the labor of wringing, which is the hardest part of the work. This invention consists of a very simple attachment to a common xvashing tub, or it may be attached to a washing machine, with which, by turning a crank handle, and running the clothes between a pair of pressure rollers, the water is pressed out, and they drop into a basket underneath ready for drying. Fig. 1 is a perspective, and Fig. 2 is a side section of the invention. A pair of india-rubber rolls are hung on a neat frame of galvanized iron, which is clamped to the wash tub in the manner clearly shown in Fig. 2; the washed clothes are placed between the rolls apd Coloring Matter of Flowers. Seine interesting researches on vegetable coloring matters have lately been concluded by M. Filbol, of Paris. He has extracted the coloring matter from white flowers, and finds it to possess the following qualities It is a clear yellow solid, soluble in water, alcohol and ether, and furnishes very beautiful lake colors with metallic oxyds, and can be used for paint- ing and dyeing fabrics of a bright and very durable yellow. It has been named xanthogene. The colors of red and blue flowers are found to be due to a similar proximate principle, which will be blue in flowers with a neutral juice, and red or rose colored in those where the juice is acid. The name of this coloring matter is cyanine, a solid uncrystallizable body, soluble in water, and capable of being applied to many uses in painting. In yellow flowers two distinct coloring substances have been found, named respectively xanthine and xanthene. Another body, named crocoxanthine, is also met with in all the species of the genus crocus. It is a solid, uncrystallizable body, of a beautiful golden yellow color, which is neither altered l)y aci(ls nor alkalies; it is solul)le in water and alcohol, but insoluble in ether; it produces, with same metallic oxyds, beautiful lake colors; and can be fixed upon fabrics, where its tine- tonal power is remarkable. M. Filbol, in a memoir read before the Academy of Sciences, gives some valu- able hints on the preservation of fresh flowers. We may preserve many flowers for a long time in a fresh state by enclosing them in sealed tubes. At the end of some days all the oxygen of the air confined in the tubes will have disappeared, and xviii have become re- placed by carbonic aei(l. If we introduce into the tubes a little quicklime it removes from the flow& rs some of their humidity, which facilitates their preservation. Lime also takes up the carbonic acid, nd the flower thus becomes placed in pure nitrogen. All flowers are not preserved alike by this process ; yellow flowers are those which are altered the least.

NEW WAR STEAMERS. We recently directed attention to this subject in an trticlc on page 361, Vol. III. ~new series), of the Sct- ENTIFIC AMERICAN, btut the great importltllce attached to it warrtmts us in recurring agitin to tlse question. We have a most inefficient navy at present in compari- son with other powers, anti one altogether inferior to what it shoulti lie considering the vast commerce of the lTnited States. Our g(ivernment has not been unmind- fiul of tisis fttct, a board of distiltgihishcd olhicers having beela ltpl)tiihltctl last year by the Secretary of the Navy to cXtthuuiue the sailing 1111)5 of tluc navy for the put pose of determining the cx~)c(liel7lcy of c(tnvcrting them into war steamers. This board has visited all our dockyards, made the reqttisite examinatiofts, and re- ported the resutits to Secretary Toucey, who has given them briefly in his late published report. It is thereig stated that it is not expedient to introduce steam power into any of the brigs, sioops or frigates, but that it is expedient to introduce it into all our ships of the line except the Delaware, which is too defective. Our steam frigates have cost each $725,000, and the cost of con- verting a line-of-battle ship in the navy into a steam fri,,ate of the same class would be only $383,000. On the ground of economy, therefore, it is recommended, that the eight line-of-battle ships, now almost useless in our navy, be converted into war steamers at a cost of $3,064,000. As this recommendation will be acted upon in some manner by Congress, it demands a thor- ough investigation, so that the most reliable concin- stons for securing a more efficient and enlarged navy may be arrived at. The French and British naval authorities have already gone through the very same experience that we are just about undurgoing. Not many years ago, they had a very large number of sailing ships of the line ; and when it became necessary to form a steam navy, it was believed that these old ships could be converted into good steam frigates at less expense than would be incurred in building new vessels. But what has been the result? In a report of a committee appointed by the British Treasury to inquire into the navy estimates in 1858, it is stated that there is but a very small saving effected in the materials, while old ships never can be made so efficient as new ones built expressly for steam. Donald McKay, of Boston, who is now in LoMon, states that the 0eneral stud well established opinion of all the dockyard officers is, that a very trifling saving, if any, is effected by the reconstruction of old sailing ships ; and then, even with a considerably improved shape, such a ship will not last one-third as long or prove as efficient as a new ship of the same class. Our government is told to beware of being seduced into the scheme of converting our old sailing war ships into steamers. Without expending any money upon them, they will answer very well for harbor defense, as block ships, but not for efficient war steamers The necessity of increasing the navy is felt and pointed out by Secretary Toucey. He says: WIsile we laave a population of thirty millions of souls, a sea cost of vast extent on tlse Atlantic and Pacific oceans; a navi0atung interest of five millions of tuns; an annual export and import trade of six or seven hundred millions of dollars, and a home trade not less valnable, it would be strange and unaccotsntable in any one to suppose that tlse federal government, in providing and maintaining its present navy, has discharged its constitutional obligation. The constant appeal of American citizens, coming to us from all quarters of the world, asking for Security and protection beyond what the government, with its present aseans, can afford them, speaks a language to which we are not at liberty to turn a deaf ear. ~ ~ * ~ S I cannot permit the present occasion to pass without most earnestly recommending the policy of a gradual, substan- tial and permanent increase of the navy, accompanied by the universal introduction into it of the usotive power of steam. Such policy is essential to the protection of our coasts and commerce, and of American citizens and their property on the ocean and in distant countries, to the preservation of peace, the efficiency of ne0otiation, the general advance- bent of our commercial interests, the maintenance of our appropriate position amon_ nations and the prompt vindi- cation of our rights and of the honor of the country, and should be subject to none of the ordinary vacillations arising from the varied success of political parties. Here we have it asserted that, owing to our ineffi- cient navy, we cannot afford sufficient protection to American citizens engaged in commerce in various parts of the world. They are continually appeal- sng for security and protection, and we cannot grant their requests. Is not this a disgrace to Amer- ica? The great question is, how shall we best remodel and increase our navy? A new era has dawned upon the world ; our old sailing war vessels, that struck terror into the Algerines and British during the days gone by, are now numbered with the relics of past ages. Steam is king of the ocean, and the nation which possesses the most powerful steam ships must be mistress of the seas. There are no two sides to this story ; it can only bear one construction. At present we have not a sin~ le first class war steamerone that can compete with tine most recently built French and British ones, and we regret that the Secretary of the Navy has not paid sufficient attention to these -~ve mean the iron- cased war wolves. Instead of frittering away ideas or money ott old and effete ships, uneasures should at ounce be taken to construct several new steamers, embracing all the latest im- provements. In another article attention shall be directed to the construction and terrific power of the new iron-cased frigates building by France and Eng- land, 25 WHERE DOES WEALTH COME FROM? If a dealer in dry goods takes an account of his stock of property, a portion of it will be set down as a num- ber of yards of cloth. Let us examine a piece of this say a piece of sheetingand see where the wealth in it comes from. In the first place, the cotton was raised on a Southern plantation. The seed was planted in the ground, and when the plant came up it was plowed and hoed till the cotton was ripe, when it was picked, baled and sent to market. By this process no new matter was created. It is regarded by chemists and philosophers as settled, that matter cannot be pro- duced by man. The elements which form the cotton were previously floating in the air or resting in the earth. All that the planter did was to bring them together in new combinations, by which process he gave them value. It will be found that all production of wealth consists in changing the relation, or form, or location of some portion of matter in a way to im- part to it valne. After the bale of cotton reached the shipping port, it was placed on board of a vessel and sent over sea to the manufacturer. By this change of location additional value was given to it. The mer- chant is snot only just as really a producer of wealth as the farmer, but he produces wealth in the same way. Both of them give value to matter by changing its location. The manufacturer draws the cotton out into long slender threads, and weaves it into a web of cloth; by this change of its formof its several parts in rela- tion to each othergiving it additional value. It then passes into the hands of the trader; who separates the large quantity into small parcels convenient for use, and transports it into the neighborhoods where it is wanted. By thus changing its location, and the rela- tion of its several parts to each other, he imparts to it additional value. The trader is a producer of wealth in the same sense as is the farmer or the manufac- turer. There was a time when there was no wealth in the world: it is now to be reckoned by millions of mil- lions, and if we examine each item of it, we shall find that all of this wealth has been produced by making changes in the form, or the relation of the parts, or the location, of the several articles of which wealth consists. Let us take one snore casethat of a ship. A certain value is given to the logs by cutting them down anti transporting them to the saw unillchanging tlncir location. They receive additional value by being sawn into plank or timberremoving the surplus, changing the relation of their several parts to each other. The transportation to the shipyard gives them additional valuechanging their location. Then, cutting away the portions which are not wanted, and placing the materials together in the ship, gives them another installment of value. The ship constitutes $50,000 worth, or $500,000 of the wealtln of the world, and all this wealth has beets produteed by changing the form of some material substance, or the relation of its several parts to each other, or its location, in such a way as to impart value to it. It will be observed that the reason why these changes give value to the material is that they advance it a step in the process of adapting it to gratify some human want. If labor is bestowed upon an article in a way not to have this effect, such labor adds nothing to its value, and of course does snot increase the wealtln either of the laborer or of the world. If a farmer works the whole season to raise a crop which will satisfy no want, his seasons labor adds nothing to his own wealth or the wealth of mankind. If a manufac- turer makes such changes in the forms of his articles as not to increase their usefulness, he does not, by such changes, add anything to their value or to his own wealth. . If a merchant buys hides in New Yosk and transports them to Buenos Ayres, where they are worth less than they are in New York, he snot only loses his own money, but diminishes the wealth of tlse world by the operation. MOMENTIJM,JOSCph W. Spragues article on the Power of Bodies in Motion is necessarily deferred until next week. We have received a large number of articles on the subject of Momentusm, in reply to Mr. Spragues communication, some of which have not yet been examined; and we cannot say what disposition we shall consider it necessary to make of them. In the meantime, we publish a reply from Professor Silliman, whiCh will be found in another colump. 26 Fire Silverplating. Although silverplating by means of the galvanic bat- tery has bccoi~e a great and most beautiful art, and now lorins a large branch of manufacturing industry, there are various articles which still require to be pre- pare(l by the old method of fire ~)lating. Having re- cently had several inquiries regarding these processes, ~xe give the following information on the subject. SILvEaLNO BILASS A ND cOPPEn. A very thiu coat of silver can lIe 1)Llt llf)0l1 brass or copper xxitl a mixturc of chloridc of silver, chalk and carlash, in equal l)roportions. The surface of the brass is first ula(le pcrfcctly clean, after which this mixture is slightly moistened with water and rubbed on with a cleats rag. Of course it is not very durable, but it answers very well for some ISlirPoses. Another method consists us a~)~)lying, in the same manner, a moist mixture of 1 psrt of silver powder, 2 of cream of tartar, an(l the same (fliantity of com- mon salt. When the surface of the brass is entirely levered with siler, it is washed in tepi(l water contain- ing a small quantity of pearlash, then washed again in warni soft water, then finally wipe(I asid lined l)efore a fire. A third muethod consists in taking 2 ounces of chlo- ride of silver, mixed with 1 ounce of corrosive subli- mate, 8 l)ounds of comnnioss salt and a like quantity of sulphate of zinc, all made into a paste with water. The l)rass being cleaned perfectly, it is covered with this paste, then dried slowly and heated very gradually up to a red heat, so as to expel the mercury which is formed by the reaction of the chloride of silver and. corrosive sublimate. The brass now acquires a silvery surface, which is hightened by burnishing. The French mnetho(l of sil verplating with silver leaf is as follows: The article to 1)0 plated is first raised to a red heat, then lmluliged into (lililte nitric acid until it becossues bright and clean. After this its surface is rubbed with umasice stosse and hot water. It is now agaiss heated to such a degree as to snake a slight hissing sound whets it touches water, in which state it is (lipped again into dilute aquafortis, which bites its surface and makes it a little rough, so as to retain the silver leaf when applied. The as tide is now heated on a warm iron plate, called a maandria, until it acquires a bluish shade, when the workman lays on two leaves of silver and rubs them (howls with a steel burnisher. After these two leaves are thins fastened on, the article is again placed on the mosaicist and heated as before; then four additional leaves are laid on and burniseed dowis in the sasise manner. Thssse operations are called charging, and mis misally as thirty, forty, fifty, or sixty leaves are thiuss laid on, according to the solidity of silverplating desired. The whole surface is finally burnished with great psessure. Articles of copper and iron can be silvered in the same manner, only the iron is miot subusitted to the iuitrie acid actionits surface ms first thorougisly clemnsed, then roughened with a file for tlse reception of thse silver. [lie following is a method of silvering iron for which a patent was taken out in England, a few years since. A mnixtisre of 12 parts, by weight, of Inercury, 2 of smmlphate of iron, 2 of murisitie acid, I of zinc, and 12 of water are heated ill an open vessel to almout 2000 Fall. TIme iron is immimnersed in this and risimbed with it until the sumrface is coated with muercury. Molten silver is now kept at hand in a crucible, and into this the asmialgamnated article is (hih)ped, whien it sooms becomes coated with the silver. Articles formed of alloys of silver and copper are whitened by removing a portion of the copper near the surface, by heating them nearly red hot, then dip- ping them into ssmlphusric acid, which eats out some of the copper and imhiarts a blanched, dead silver ap- pearance to the smmrface Articles of alloys composed of copper asid gold, when treated in the sanie mmsanner, but using nitric instead of sulphuric acid, acquire a beaustiful color, resemblislg whsi t is termned Tussean work. The solder which is employed by silver- platens is consposed of 2 parts silver and 1 of brass. The brass is a compound of 233 parts of copper and 100 of zinc fused togetherthe copper melted first in the crucible, then the zinc added, and the alloy thus made east into ingots. Silver solder melts freely in a clear charcoal fire for whidll a blast is employed.

English photographers are conducting with great learning and ingenuity a series of experiments with tIme view of obtaining mm artificial light for taking photographs. We find in the Londomm P1iotogm~phic Noel the following account of some preliminary exiler ilnents whmicli were Inadle 1w Mr. (rookes ill 1856, at the expemise of the governument. It will be remneniber- ed that the cliemnical or actinic rays of the sunbeaum which llrodumee the chmmnges ot shade in the photograph are entirely differeimt from those which affect the eye, hence an artificial light might be very brilliant to the eye and still cxert very little power upon the sensitized phute or paper. The two great sources of artificial light, electricity and chmeimmical action, were successively tried, tIme forlner, however, not being comisidemed so promising mm field as the latter. owing to time great expense and difficulty muttending its use, and for the fmmrtlmer reason that the requirements of the case rendered port- mibihity a great consideration. Trial was mnade of the electric egg, or the lumminous glow which is pro- duced when the secondary current, from a powerful indumetiomi coil, is passed throumghm highly attenimated gaseous media enclosed in glass tubes. But althouohm a a spectral mmnalvsis of this light showed that time photo- graphic rays of light were presemmt imm emmormnous qualm- titles in proportion to time visible rays, they were in- smmfficient to atfect a sensitive collodion plate when re- flected froni an object, removed to any considerable distance.

Mr. Crookes was perfectly successful imi tmmking good i)lmotographs by tlmis light, but a sit was probable that greater success might be obtained at a less expeimsc 1w directing attentiomi to sonic otimer chemminical source of light, the experiments in the above (lirectiomi were dllseomitintled.

Phosphorus burning 1mm oxygen produced such a brilliant photo- graphic light, that if it were possible to devise a safe and convenient apparatus for its production it nmight doumbtless be made available for photographic pmmrposes. Phmotographs were likewise taken by Mr. Crookes with this light. An attenmpt was then made to combine botlm the comlhustible body mind the source of oxygen together, and so produmce a light analogous to those employed for pyrotechnic pumrposes. Mr. Southmby, the invell- klmown artist in fireworks, was employed to mnake several intense highuts of different colors, and in conve- nient forms for experimenting with. These experi- mnelmts were, however, discontinued, as although the light might perhimips have beems obtained sufficiently strong for the purpose, yet the volunmes of smoke arising fronm the conmbustiomm proved an llssurulOunta- ble difficulty; and even could this have been obviated, time results of combustion, such as sulphurous acid, and in some cases even coumpounds of arsenic and an- tilliony, would serioimsly endanger the health of the operator. The bcd~ ilyhi, obtainedi by employing an onlinary argand gas blmrner within Oxvgdn, insteadi of muir, was experilnentedl withi, maul fotmini not to yield auftuiemmt mictinic light.

The ordinary apparmltus was found to be quite insufflciemmt for the purpose besides being attemmded with considerable danger.

[Reported for the Scientific American.j TIlE CALORIC PROPELLER ~PIhIMERA. The hull of this vessel was constructed by Messrs. Sneeden & Co,, of Greenpoint, L. I. 1-Icr owners are Messrs. Pesant, Brothers & Co., of this city, and the route of her intdn(le(l service is the coast of the island of Cuba. As the introduction of Captain Ericssons hot air engine into this vessel is regarded as perfectly successful, we give the annexed minute details of her hull and machinery. Length between perpendiculars, 135 feet; extreme length on spar deck, 144 feet; breadth of beam, 22 feet; breadth over guards, 34 feet; depth of hold, 9 feet; draft of water at load line, 6 feet 3 inches; dis- placement of vessel at load line, 10,800 pounds to the inch; tunnage, 330 tuns. Her frames are of angle iron 3x3x~ inches, spaced 18 inches from center to center, every alternate frame having a vertical floor plate, 9 inches deep and 5-lfiths of an inch wide, se- curely riveted thereto. There are five fore-and-aft keelsons, viz: one center, 12 inches tlecp; two sister, 10 inches (leep, and two bilge, which are 8 inches in depth; these keelsons are made of iron 5-l6ths of an inch in thickness, and are thoroughly fastened to the shell of the vessel, and strengthened on their top edges by bars of angle iron 3~ x31x7-1Gth inches. The deck beams are of angle iron 6x~ inches, and ate rivcted to tile head of every alternate frame; they are also secured by plate iron knees, ~ of an inch in 4 thickness at each end, and have scantling beams at- tached, extending out 6 feet beyond the hull, forming a guard all around the vessel; the ends of the above beams are flanged, and receive a stringer iron 6x~ inches around their extremities. The guards are (liagonally braced with iron rods fastened to the deck beams and to the sides of the ves- sel. There is a stringer plate 15 inches wide and 5-l6ths of an inch in thickness, extending entirely around the hull and fastened to every deck beam, and also to the shell of the vessel, by a bar of angle iron 3x3x~ inches. The plating is of various thicknesses, as follows: thickness of keel, 9-lOths of an inch; do. of garl)oard streak, luch, (10. from garboard streak 5 to turn of bilge, 5-1(iths of an inch; (10. of wale streaks, ~ inch; the rivets in her keel are ~ inch dia- 4 meter, and those in the plating are ~ inch in (ha- meter. The Priotera is fitted With a (loulde-aeting, condens- ing, pressure, calorie engine (Ericssons patent) ; (ha- meter of cylinders, 40 inches; length of stroke of pis- ton, 24 inches; diameter of propeller, 8 feet; pitch, 16 feet; length of same, 19 inches; length of blades, 30 inches; weight of the engine, propeller, & c., 70,000 pounds; length of engine in the vessel, 14 feet; length of engine room, 8 feet. She is also supplied with two heaters, which keep tile pressure of air at 85 pounds per square inch; the consumption of coal (anthracite) per hour is 85 pounds; the heaters are located in the hold. In addition to these essential features, site Itas 2 smoke pipes; independent ru(lder post, and 2 athwart- ships watertight bulkheads made of ?~ and 3-l6ths of an inch iron; the whole is vertically stiffened by bars of angle iron 2Ix2~x5-16ths inches, placed 3 feet apart. Said bulkheads are perforated with suitable holes, which are provided with valves to shut watertight. Her rig is that of a schooner. The machinery was con- structed by Mr. C. H.

By his untiring efforts for more than four years, this inventor has succeeded in bringing his ma- chines to heretofore unattainable perfection. They can be used with equal advantage in dwelling houses and in stores. Their action is safe and steady, and so per- fectly (hire(t thtat nothing can get out of order; they are moot liable to jar, sl)ill or break the articles con veye(I (In tltem.

They Can be used as a fire escape if the communication with the stairs is cut off, as a person can ~tarid on the top and hoist or lower himself with ease; they require less head room than other dumb waiters, and they can be fastened in any story and left without danger of their falling; and, finally, they can be made cheaper than others, considering their durability and the advanta- ges gaine(l. We can speak of the utility of this inven- tion, from having used one of the dumb waiters for some time in our dwelling, with great satisfaction. The inventor, Andrew Murtaugh, No. 1,272 Broadway, corner of Thirty-fourth street, this city, will be pleased to give further information in regard to his invention. SEWING NEEDLES. This invention, by Henry Essex, of Haverstraw, N. Y., is adapted to needles for all ordinary kinds of sew- ing by hand. It consists in giving to needles a trian- gomlar form in the body or wider portion, but retaining the usual round fomm at and near the eye and point. The object of this invention is to give them greater strength without giving them greater substance. What is Wealth h The wealth of the world, of the country, or of indi- viduals consists, to a very small extent, of money. If all the money in the world were instantly annihilated, there would still be very rich nations and rich people. The wealth of a farmer consists in acres of land, in houses and barns, in droves of cattle, in stacks of hay, in bins of grain, & c. The wealth of a manufacturer consists in his manufactory, his machinery, his stock of raw material and of manufactured goods ; the wealth of a merchant, in his ships and merchandise. It is not the circumstance that these articles will exchange for money that makes them wealth. It would be much more proper to say that a bank bill is wealth because it will buy a barrel of flour, than it would to say that a barrel of flour is wealth because it will exchange for a bauk bill. Two things are requl- smte to make any material substance an article of wealth ; one is that it should be desirable, and the other that it should be difficult to obtain. Air is as necessary to our existence as any substance whatever, but from the fact that nature has provided it in bound- less abundance, it constitutes no part of our wealth. The same is usually the case with water; but wherever water is difficult to obtain it becomes wealth. There are large cities in which all the water used is broomght on mules backs or mens heads, and sold like any other commodhity. Any article, in order to be property, must not only be (hifilcult to obtain, but it must satisfy some human want. It makes no difference, in this respect, whether the thing wanted is good for people or in- jurious, provided only that they desire it; therefore rum, arsenic and faro checks are just as really wealth as bread or Bibles, or volumes of tloe SCIENTIFIC AMER- ICAN. In another article we have pointed out just what re- lati6n mnoney does bear to the whole wealth of noan- kind; we desire hoere merely to call attention to the fact that it is no more wealth than any other kind of property, and that it constitutes a very small part of the wealth of the world. There were many rich men before there was any money. THE NEw FACTORIES AT LAWEEFCEThe work on the Pacific Mill in Lawrence is progressing as fast as possible. A large portion of the machinery for the extension on this onill will not be due until next April. As fast as it arrives, it is put in working order, but the company has never contemplated getting the ex- tension in operation before early Spring. The new Pemberton Mill is in the same position. Machinery is daily arriving, and being put in running order, and the work, notwithstanding monetary ups and downs is h)eing hurried along to completion as heartily as ever. But the mill will not get fairly started before Spring. A PHOTOGRAPHIC QUIETESTThe following novel and effectual method of keeping sitters quiet while their pictures are being taken is from the fooonal of P/tote- grcep/ty:We have read a story of an artist way down Soumth in Dixie, who adopted a imovel expedient to keep his sitter quiet. He Itad tried all sorts of snasioums without suc- cess, when it occurred tu himo titat the strongest of all fin- noan motives is fear. As soon as he had comupleted his ad- justments, he suddenly draws a revolver, and leveling it at the sitters head, he exclaims in a voice and with a look suggestive of head and gunpowder : Dare te move a muscle, and Ill blow your brains out.

In former numbers of the SCIENTIFIC AMERICAN, we have endeavored to correct the numerous statements which have recently been published respecting the explosive gas engine of M. Lenoir which has lately been on exhibition in Paris. It was given out that this was a new motive power superior to steam, and that it would, in all probability, supersede it. We stated that it was, in almost every feature, the iden- tical invention of Dr. Drake, of Philadelphia, which had been on exhibition in the Crystal Palace in this city. Our opinions thus expressed have been verificd by the accompanying illustrations of Lenoir 5 engine, published in a late issue of the London Engineer. The motive agent employed in this engine is explosive gas. If one volume of the common gas which we use for illumination be mixed with eight volumes of at- inospheric air it becomes saturated with oxygen and as highly explosive as gunpowder; and if a spark of electricity is passed through it an explosion will imme- (liately ensue. The engine here represented is similar in most of its features to a common horizontal one lint it has no boiler, and, instead of steam, charges of gas mixed with air are admitted and ignited alter- nately behind tile piston to give it a reciprocating motion by the expansion which results. Fig. 1 is a side elevation; Fig. 2 is a vertical longitudinal sec- tion, and Fig. 8 is a transverse section. C is the cyl- iu(ler, and P tIle l)istOn. The cylinder is double leaving a space around it for a stream of water to keep tile metal from becoming too highly heated by the frequent explosions. Two slide valves, T T, are used, and if are the positive and negative wires of a gal- vanic circuit. TIle gas is admitted to tIle feed box of tile valves by the pipe, C, and the air by the pipe, A. In tIme front part of the engine fralne are iron rods, c d, witlm circuit breakers and closers on them. The ends of the wires, f.f, are of platinum, and pass into the cylinder, wimere tiley become highly heated when the current of electricity is sent through them. The gal- vanic circuit is broken and closed alternately for igniting the charges of gas behind the piston by pins on tIle rods, c d, which are operated by a slide on the piston rod. The wires, f f, are insulated from the cylinder where they pass through it by means of glass tubes. In Dr. Drakes engine tIme gas was ignited by heated platinuul cups without tile use of a galvanic battery, and tilis was a more silnple method than that adopted by Lenoir. Explosive gas engines are not affairs of yesterday in Anmerica, for a patent was granted for one on October 7 1846, to Stewart Parry, which Ilad a water chamber surrounding the cylinder, exactly like that represented in tile above figures, and for tIme same purpose. It is stated that the above engine has been reglliarly at work for several months at No. 85 Rue Rousselet, Paris, but we deny the correctness of this statement, for the mechanism in the interior of the cylinder must soon become foul with hard lamp black the residium of the gas. Such an engine requires to I stopped frequently and its interior scoured out. Economy of Fuel in Xron Works. Mr. John Player, blast furnace manager, commumn- cates the following interesting information to the London Engineer, regarding the use of the gases formed by the combustion of fuel, either alone or in conjunc- tion with the fuel itself, for cases where a high heat is needed. He says: About tile year 1840, Mr. Farler de Four took out a patent for puddling with time gas taken from time top of a blast furnace. I saw one of his furnaces at work mmm Wurtemburg, in 1843; it worked very well occasionally, but not regularly; it was like a common puddling furnace, with a stack about 5 feet imigim. TIme gas was conveyed to the fire bridge in tubes, and, being met by jets of imot blast (about 400 feet per minute at l.Ib pressure), a welding Imeat was produced. Many furnaces of tIme same construction Imave been since used at various iron works in Germany, Russia, & c., time ~as being gemmerated from wood, coal, peat, & c., in a small cupola, from wilence it is forced into time puddling or other furnace, as above described and, I believe, in every instance with great economy. In Bavaria, wimere ligmmite is used, time form of the corn- momm puddlin~ furnace is retained, but witim a very large fire place ; blast is supplied tImrouglm the ashpit, part of wimich passes througil the bridge and unites witlm the gas or fiamne generated by time fimel, and produces time desired effect. 1mm America, imowever, I tlmink tIme greatest effect is pro- duced by time proper combustion of the gas or smoke in a welding furnace. I visited the Readin,,, Steam Forge, in Peunsylvammia, in 1857, at wimicim place time main shaft lbr the Adriatic had just been made; my informant stated it weighed 32 tuns. Time furnace in wimicim tlmis mass of iron Imad been welded was, when I saw it, imeating an immense crank. Blast was supplied to the fire by a large fan, and time bars and fire bridge so arranged Ilmat a sufficiency of air to consume time smoke was forced timrouglm time fuel at time bridge and timus, being imigimly Imeated, preduced time desired effect. Most of time steel melting works in Anmem-ica use blast immstead of time draugimt of a stack. Anotimer very excellent plan for time econonmy of fuel, patented by a Frencimnman, imas beemm used for a lommg tinme imm France at a factory of steel springs. It commsists of two fire places, witim a imearth between limem, on whicim time steel to be muelted or imeated is placed; time arrangement is such timat time gas or sumoke from time fires must descend througim time incammdescent fuel, wimeroby it becomes imigimly Imeated previomas to its comubustion imm time heartim. Ilaving built and worked one of tlmese furnaces, I can speak to time intense Imeat pmoduced. Anotimer very neat metimod of economiz- ing fuel I saw at a glassworks in Saxommy, for time manufac- ture of simeet glass. Time coal was consumed in a small sqamare furnace, witim five bars at time bottomotimerwise, like a cupola witim a closed top ; time smoke or gas was con- veyed tlmrouglm simeet iron tubes under the floor of time blow- ing imouse, and into time bottom of time cone, in wimich stood smx open top molting pots; sufficient air was admitted througim small tubes to mingle with time gas to produce tlme me- quired Imeat; the air and gas tubes were supplied with tlmrottle valves. Time imeat was extremely regular; time fur. nace Imad been at work about six years at time time I saw it, and, altimounh a colliery belongimag to the same proprietor was worked witlmin a few yam-ds of time same premises, yet line told me he had found great econom adopted. y by the metimod line IT iS a noticeable fact that New York has a greater proportion of female artists than any other city in the world. Many of them are very good; some of them rank with the best. OF THE SCIENTIFIC_AMERICAN. THE BEST MECHANICAL PAPER IN THE WORLD. SEVENTEENTH YEAR? VOLUME P/NEW SERIES.

VOL. IV.---NO. 8. NEW YORK, JANUARY 19, 1861. NEW SERIES. Improved Spoke Machine. If there is one thing more than another which sur- prises Europeans when they CO~C to the United States, it is the great ninuber of elegant pleasure carriages which they behold wherever they go. This is n6 donbt princi~ally (inc to the more general (listril)ntion of wealth among onr peOl)le, l)y which they are enabled to obtain ami use such vehicles; but, at the same time, it is also due, in a great measure, to the more general application of impro~& d machinery for cxecnting various kinds of work, the manufacture of which in other countries, is performed by haml labor. Thus in making the parts of wheels for carriages, alone, we cm- ploy one machine for fabricating the hubs, another for the felloes, and still another for the making of the spokes. Every improvement, however small, in this (lepartment of American in(lustry is of much import- ance from the fact of there liemg such an endless num- ber of wheeled vehicles em- ploye(l. The accompanying en- braving is a Imerspective view of a machine for tmun- lag the spokes of wheels, for which a patent was grante(l to John Gilchrist, of Berlin, Wis., on the 8d of October, 1860. 13 is the rotating cutter shaft, on which are secured two or a n y desired number of blades. Each blade is as long as the s1)oke to 1)0 cut, so that its whole length is operated upon as the cutter shaft rotates. The cutting edge of each blade is slight- ly curve(l where it is inten(l- ed to cut the thicker end of the spoke, so as to l)rodlice the slightly curved outline upon it. 13 is a pulley which (Irives the pulley on the emit- ter shaft by a belt L ; powei is communicated i)y the belt, X, to drive the main shaft, 5, of the machine, as represente(l. The piece of wood, W, to be formed into a spoke is held in the car- riage, I, between the center- iug screw, an(l the sharp e(lge of the pattern, C, which is fastened to the inner end of a short shaft which has its hearings in the car- riage, I, and has on its outer end the worm wheel, 0. The latter wheel takes into the thread of a long screw, D, supported in bearings, a a. The screw shaft re- ceives motion from and is connected by the pulleys and belt, J, with, the main shaft, S. The stick, W, is secured for cutting by the screw, as shown. A guar(l, E, is fastened to the main frame at one end of the cutters, and it is arrange(i in line with the pattern,. C. The feed carriage, I, slides on ways, N N, and it is guided at the en(l of the center screw by a pivot, P, projecting from the bottom of the carria(re underneath the screw into a groove cut into the way, N. It will be observed that while the feed carriage, I, shi(les in the ways, N N, it can also swing around the pivot, P. One end of a strong spiral spring, G, is fastened to the middle portion of the lever, H, which is pivoted to the main frame at A. The other end of this lever is confined with a pin, IR. As represented, the spiral spriu~, G, bears against the back of the feed carriage, I, and pushes it forward to the cutter until the pivot, P rests against the for- ward end of the groove in the ways, and the pattern, C, against the guar(l, E. As the driving shaft revolves, the cutter shaft and that of the screw rotate at the same time. The cutter revolves with a high velocity, l)ut the screw, D, rotates very slowly, thus causing tIme worm wheel, 0, the shaft of the pattern, and the stick, XV, to revolve with a like slow speed. The whole circmnference of the stick, XV, as it rotates, is gradual- ly exposcd to the action of the cutters until it is formed according to the pattern in the machine. When the pivot, P comes against the forward end of the groove and a spoke is completed, the feed pressure of the spring, G, on the back of the carriage, I, is re- lieved by releasing the lever, H. The carriage is then (lrawn back from the cutter, B, the centerina screw turned hack, an(l the finished spoke, W, removed, to make way for another stick, to be cut in the same man- ner. TIme pattern, C, in its rotation, always bears against the guard, E, and the pivot, P rests uniformly against the end of the slot in the bearing, N. The pattern end of the feed carriage, I, is therefore made to recede from or approach the revolving cutter, as the diameter of that portion of the pattern which is in contact with the guard, E, increases or diminishes. The pivot, P, serves as the center of this motion. As the pattern corresponds with the shape of the thicker end of the spoke, the stick of wood is cut accordingly and with a tapering, cylindrical form towards the end that is held hy the centering screw. A perfect spoke is thus produced during one revolution of the piece of wood fed forward to the revolving cutters. The patent for this improved spoke machine was ob- tained through the Scientific American Patent Agency.

The following useful information on this subject is taken from the able Paris correspondent of the Lon- don Photographic Aews:One of the earliest applications of photography consisted in the reproduction of an- cient manuscripts; but this application has never taken the development expected of it. By the em- ployment of Colonel Sir Henry James method of zinco-photography, a sphere of the greatest interest and usefulness is opened up, which we hope to see ex- tensively utilized. There are numerous rare historical manuscripts, fac-sirniles of which would be desirable additions to public libraries in all parts of the world. These copies could be produced by the process of zinco- phuotography, at an almost insignificant cost. A very curious fact has been recently brought to light, which touches the question of photography of the invisi- ble, viz., that the effaced or faded portion of the writing of old manumscripts is restored in the pho- tographic reproduction. Thus, the copy becomes more legible and perfect than the original. M. Vin- cent, one of the members of the Acad6mie des Inscriptions et Belles Let- tres, recently presented to that body the firstfec -simile of a manuscript repro- duced photographically by M. Silvy. It was the Sforza manuscript, the original of which is in the possession of the Marquis dAzehio. It is scarcely necessary to remark that all the designs and ornaments of this pre- cious work are reproduced with marvellous fidelity. But the circumstance that deserves particular men- tion is, that certain pass- ages which could not be de- ciphered in the original old parchment have actually been revived. This is par- ticumlarly striking on the last page, where a note, written in German, under the signature, has not only become visible, but legible, while not the slightest trace of it can be discovered in the original. This remarkable circumstance is thus explained by M. Figuier On old parchments the ink, under the influence of time, assumes a yellowish tint, which often becomes undistinguishable from that of the parchment, so that it cannot be read without the greatest difficulty. But, during the photographic pro- cess, the brilliant and polished parts of the parchment reflect light much better than those where the ink has been deposited. However colorless it may appear, the ink has not lost its anti-photogenic qualities, opposed to the photographic ones of the parchment, and, thanks to this opposition, black characters may be ob- tained on the sensitive collodion in exchange for the much paler ones of the original. IN the London Eagiaeer, a correspondent states that the opinion is erroneous, which was first broached by Professor Faraday, that a drop of water contains as much electricity as an intense flash of lightning.

BY JOSEPh W. SPRAGUE. It is a wellrecognized principle in mechanics that whatever amount of power has been expended upon a bO(ly in changing it from a state of rest to one of mo- lion, the same amount of power will be yielded up by the body to whatever Inings it back to a state of rest. When, therefore, we (letermine the amount of power necessary to impart to any body at rest the velocity v, we also determine the amount of power necessary to stop the same body when it is moving with the velo- city v, for tli~ two amounts are equal. All our knowledge of force and the work which it accomplishes, or l)Ower, is derived from experiment. Let us therefore take some well-known instance of force at work, and (lednee from it a general law-. The most familiar of all forces is grenity; the intensity with which it nets upon any body is measure(l lv the weight of that l)ody. Experiment shows that a body abandoned to the sole action of gravity aequir~s, at the en(l of one second, a velocity of 82.2 feet per second; at the end of two seconds, a velocity of 64.4 feet per second at the end of three seconds, a velocity of 96.6 feet per s(cO]lil; at the en(l of four seeon(ls, a velocity of 128.8 feet per second. If then v represent the velocity in feet per second; /, the number of seconds (hiring which the body has been abandoned to the sole action of gravity; and g, the experimental number 32.2, we have r =g. 1)uring the first second, the body falls through a space of 16.1 feet; in two seconds, through 64.4 feet; in three seconds, through 144.9 feet: in four seconds, 257.6 feet. If then s represents the space, in feet, pass((l over 1w the body, we have s equal the l)ro(luet of the time and the mean velocity, or s=[ (oIi) +2 ] X t=vt~yP+ 2. Suppose an iron ball weighing 1,440 lbs. to rest upon the piston of a vertical cylinder having an area of one square foot. Consider the piston itself devoid of weight, an(l moving without friction. Admit below the piston steam having a tension of ten pounds per square inch, or 1,440 lbs. per square foot. The pies- sure of the steam (1,440 lbs.) upon the under side of the piston just ihalances the weight of the body, and there is no motion; that is, the expansive force of I lie steam just equals the force of gravity acting upon I lie boily, an(l the two neutralize each other. Next double the tension of the steam, making it twenty pounds per square inch, or 2,880 lbs. per square foot. We now have a downward force of 1,440 lbs., auiil an upward force of 2,880 lbs. The resultant is an upward force of 1,440 lbs.; that is, under the com- lined action of stcam an(l gravity, the ball has the same tenilency to rise that it would have to fall under the sole influence of gravity. We know, then, that tli( 1)istOn and ball will, in one second, rise 16.1 feet, an(l acquire a velocity of 32.2 feet per second; in two secon(ls, rise 64.4 feet and acquire a velocity of 64.4 feet per second; in three seconds, rise 144.9 feet and ac(phire a velocity of 96.6 feet per second; in four seconds, rise 257.6 feet and acquire a velocity of 128.8 feet per second; and in I seconds, rise s=g122 and acquire a velocity v=gt. We have for the cubic feet of steam consumed, the area of the piston multiplied by the hight it rises, in the first second, 16.1 cubic feet; in two seconds, 64.4 =4X 16.1 cubic feet; in three seconds, l44.O=l6.1X9 cubic feet; in four seconds, 257.6=16.1 X16 cubic feet; in / seeon(ls, 16.lx,2 cul)ic feet. Thus it will be seen that while the velocity increases as the numiters 1, 2, 3, 4, & c., the power expended (steam consumed) varies as the numbers 1, 4, 9, 16, & e.; that is, the power expended in producing any velocity varies as the sqeare of that velocity. In de- termining the ab.tolete quantity of steam used in pro- (lucing velocity, it must be remembered that one-half of the above quantity is consumed in overcoming the resisting force of gravity, the other half alone pro- ulucing motion. This would not, however, affect the tv/a/oe quantities used. For deducing a general rule, let W represent the weight of the ball in pounds; a, the area of the piston in squnre feet; an(l b, the tension, in pounds, per shuare foot of the steam. Making, as before, the pres- sure on the piston twice the weight of the body, we have eXb=2W. The quantity of steam consuimeth, while the piston and ball rise through .o feet in / seeon(ls. acquiring a velocity of v feet per second, is aXs=ex(g/i+2) aX (g2)x(vg)2=ax(vi-i-2g). As half of this is consumed in resisting the force of gravity, we have for the steam actually employed ho producing the velocity, (e2) X (ri2g). Time introduction beneath the piston of 10 cubic feet of steam, having a tension of 20 lbs. per square foot, is equivalent to raising 20 lbs. 10 feet high, or 40 lbs. 5 feet high, or is equal to 20X10=200 feet-pounds, whatever be the size of the piston. Hence, if we mul- tiply the cubic feet of steam used by time pressure (b) of the steamn per square foot. we shall have a correct measure of the mechanical effect, or power, expended in producing the velocity v. Representing this me- chanical effect by B, we have B=bx(a2)x(vo2q) (ab+2)X(ei+2g)Wx (vi+2g) =~ [(W-i-g)Xv2]. This last expression measures the power required to produce the velocity v in a body whose weight is W, an(l consequently measures the power stored up in this body, when moving with the velocity v. This power the body will yield up when it is forced to come to rest. In (letermining the unit of mass of a body, physicists have taken as the unit that body whose weight is 32.2 lbs (or g). This choice was an arbitrary one, as any other might have been made just as well; the ob- ject oC taking this peculiar value was to simplify the very result we have just obtained. If M represents the mass of a body, then M=W+g. Substituting this above, we have B=~Mv2. The product Mci is called by physicists vis viva or living force. Hence we say the power stored up in a moving body is equal to one-half its vis viva. AMERICAN ENGINEERS ASSOCIATION. [Reported for the Scientific Ameuicmum.l On Wednesday evening, Dec. 26th, tIme regular weekly meeting of this association wns held at its room, No. 24 Cooper Institute, this city John. C. Merriam, Esq., President, pro tern.; Benj. Garvey, Esq., Secretary. MIScERLANEOUS BuSmxzss. Cares Low Water DefectorMr. A. Carr, of Jersey City, submitted to the association, for its opinion thereon, his patent low water (letector. In its opera- tion no alloys are used, and a new mode for the dis- placement of water is claimed. These points are con- sidered by the inventor as very important ones. Mr. Carr, imy the aid of a drawing, proceeded to explain the manner of its construction and the principles in- volved in its operation. His remarks were listened to with considerable attention by the members present, after which his invention was referred to tIme Committee on Science and New Inventions. This conunittee, through its chairman, Mr. Louis Koch, then presented tIme suib- joined report Your committee having before it Roosevelts Anti-Emic- tion Axle~ and Wests Double-Acting, Anti-Freezing, Lifting and Forcing Pomp, would respectftmlly submit their report on said inventions, based on a fmmll and careful inspection and consideration, as follow-s 1. That in regard to Mr. Roosevelts Anti-Friction Axle, it is found that the principle being to insert an axis between a series of small rollers working between two plates, forming tIme sides and the rhu of the w~hmeel, your conm~ mittemo find that the area of friction presented by time grooved and tongued rollers, togetimer with time bearing of time side plates, is greater titan a common bearing would h)rvsent, amid that time stability of time wheel is less when de- lmeudeumt ~n such narrow limits as tIme model indicates would be allowed, titan in a proportioned sized 1mb in a common bearing, and that iui consequemmee of time friction rollers presenting so small a surface of bearing to time axis every tendency of side motion will necessarily increase time wear and tear of time small bearing of tIme side plates. In consequence of the above stated reasons, your comniittee are enabled to find hiroperties in this imivention, timat would make it as valuable as a commoum axle bearing has been found to he. 2. That in relation to Wests improved pump, it is found that, in regard to time claim consistluog in a vemot-imole over time suctioum hhisthum, so timat time water remaining in time pump immediately after use will flow away, it is time opinion of your committee that, though there is umecessarily a small loss of water during time act of pumping titrough timis imole, this inconvenience may be regarded of little consequence, time main object of non-freezing being secured, w-imich is particularly of importance wimenever time pump is of diffi- cult access. Your committee also think the arrangement of two suction valves in time air chmaumber and in time bottoum of time lower cylinder, respectively, is good, insuring a greater guarantee against choking. Time coummittee have also been favorably impressed within time arrangement of time combined piston, working at time same time in an upper and lower cylinder, timis hatter being twice the size of the former, thie quantity of water or liquid discharged being dependent on the diameter of the upper smaller cyhinder and tIme lengthm of time stroke, eachm piston being packed with overlapped expansion leather rings, the friction is alu-ays in proportion to the amount of work done, time suc- tion piston being always umder water when working, and the upper piston receiving a constant pressure from Imelow-, time action of time atmosphieric pressure is counterbalanced; timis is insured furtimer by extending time exhaust pipes over amid above the upper portion of time upper piston, wimereby time cimamber between time two pistons is kept full of liquid during time working of time ~munmp. Timerefore your coumumittee wuould respectfully recommend timis punmp to time favorable comisideratien of the society.

Tioe fohlowiuog, from hoe Cqmeaiiral News, is aim extract from a recent lecture on this interestiuog suibjeet lty Professor Laukester, of London, Emogland We find sugar more generally contaimied in time jumices or tIme sap of plants than in any other form. Sugar has tIme remarkable property of fermemitation, and it is duiring the process of timis cimange of suigar that alcohinol is produced, therefore you see we can moonke aloehord frono starch, lout we moist first convert tIme starch into sugar, and I now call your attention to th( chemical composition of suigar as imeing of the sanoc kind as starch. I have here some sugar, amid I wihi submit it to the actiomo of a suibstance that will draw away the water, and leave the carbon to act freely. I first dissolve it in warm water, and will timemo pomur umpon it some suulphuiric acid, amid this will withdraw a sufficient qumantity ofwaterfor you to see thoat time sugar contains a large qumantity of charcoal. You see, now, what a large quantity of charcoal is developed from this 34 sugar-there it is black, boiling, and hard from the action of the sulphuric acid. It is thus that we can demonstrate the presence of the charcoal, and in this way that very useful material which we call blacking is manufactured. A quantity of sugar is taken and sul- phuric aci(l is added, and you see in what a shining state the carbon is left when it has been submitte(l to this l)rocess. In this way you see we can prove that the starch contains the same material. Let me now call your attention to the history of the l)lant in relation to the sugar. During the germination of l)lants sugar occurs in great quantities. If we throw these seeds into the ground, the little embryo in the interior grows, and that process is called germination. There is a large quantity of starch surrounding this little embryo, and as it grows the starch is converted into sugar, an(l this starch is as necessary for young plants as it is for Young children. Now this is the case on a very large scale, in the process of malting. The nialtster takes his barley, immerses it in water, causes the seed to germinate, and then he roasts the young plant, seizing the sugar which it has just made, and converts it into beer. Ilieu again we find the stems of ilauts in cert:iin seasons of the year contain large quan- tities of sugar thus, the whole of the grasses, wheat, barley, oats, rye, rice, and maize, contain sugar in their sterns when they are about to flower; and it is just at this season of it~ development that the sugar-cane is nse(l by inai~ as an article of diet. We need not, how- ever, confine ourselves at all to the sugar-cane. The only reason why we get sugar from nothing else arises out of our fiscal system, revenue being obtained from it, an(l sugar not being allowed to be grown in this coun- try. InCh ma they obtain sugar from the Sorglosuisecchar- c/urn, which, like the sugar-cane, belongs to the family of grasses, and is cultivated in the North of China for the sugar it contains. Then the maize has been culti- vate(l in America and Mexico for the purpose of obtain- ing sugar. When Cortes conquered Mexico he found the natives cultivating the maize and crushing it for sugar. r1~hIe cocoa-nut tree of the island of Ceylon is a principal source of sugar, and there are a class of men whose occupation it is to ascend these trees and put on the blossoms of the tree a calabasli to catch the exuding juice, which is an article of (liet known in Ceylon as tod- ily, the men being called toddy-drawers. Again, at the h)1l(lding season, the sap of plants contains sugar. The common osier has it. The birch, too, in England and Scotlan(l is tapped for its sugar, and is converted in Sc ithancl into an effervescing wine, exactly like cham- pagne. In America there is a plant which contains so large a quantity of sugar that I think a third of the sugar consumed in the United States is obtained from it. It is the maple. Then the beet-root, the carrot, and the turnip contain sugar. When Napoleon Bona- parte excluded cane sugar from the French markets, they set to work to supply the loss, ami adopted a German process, which resulted in the production of a very successful sugar from the beet-root and now, after years of production, sugar manufacturers are enabled to compete with the manufacturers of sugar from the sugar-cane- There is also another source of sugar in tIn fruit which we eatthe fig, the pear, the apple and the orange, would be unpalatable but for their sugar. I will now (iraw your attention to the different kinds of sugar. Although sugar is always sweet, and we call everything that is sweet sugar, yet there are various kinds of sugar. Sugar is obtained from milk ; and we can, by taking the livers of animals an(l digesting them in water, obtain large quantities of sugar called liver- sugar, showing that animals have the power of pro- (lucing or secreting sugar. Thins we have several kinds an(l I would just call your attention to the four princi- pal Sources. rule cane sugar is found in the stems of plants, and in all those cases where it is procured before the flower- ing of plants, and in the roots of plants; so that the beet-root sugar an(l the or(linary sugar that we eat from (lay to day is cane sugar. But we obtain another sugar from fruit, which is uncrystalhizable ; an(l that fruit sugar is almost i(lentical with another, which is called starch sugar ; and fruit sugar and starch sugar are both known to chemists hy the name of Glucose. The cane sugar is called Sucrose, and the sugar obtained from milk is called Lad use, while liver sugar is called Hepa- tose. Those are the four sugars. I told you just now that the liver contains? quantity of sugar; I may say that I hiehieve it has beu n (lemonstrated that the liver ihoes not contain sugar itself, but a matter which is easily converted into sugar; so that the instant you expose it to the air it becomes converted into sugar. We have in glucose a substance much more easily de- composed than the other forums cf sugar ; and I will finish by stating that this cane sugar is con- verteci into this form of sugar, and then we have either glucose, lactose, or hepatose in the system. It is in that manner that the starch is converted into sugar, so that it becomes a heat-giving substance capa- ble of maintaining heat in the animal body. The Needle Women of London. A correspondent of the London Times, describing one of the great mautna-making establishments in that city, communicates the following facts: Work is commenced every mom-ning at 7 oclock and con- tinued till 11 at night-a period of sixteen hems, the only imitervais allowed being about ten muinutes for each meal; the total amount of tinme allowed foreating their food, 1 was going to say, but, surely, bolthmg it is the more ap- prolmi-eate phiraseheing forty miimutes per day; tlums leav- ing fifteen hioumrs and twenty mimimmutes as the period devoted to work.

In many receipts for preserving hams, molasses is one of the principal ingredients, but Mr. Marguseritte, in an article in LIumveafion, asserts that sneat may be preserved by molasses alosie in ti-ic most perfect maim- ncr, and with tine folloimising important advantages: It has an agreeable flavor, it produces no scurvy or otliner disorders whinich result from time use of salt food, and it may be prepared at a moderate price. The process consists simply in custting tine uneat imito pieces of ninoderate size and dropping them into mo- lasses, such as is obtained from time sugar nmaruinfac- tories or refineries.

We find in LIchen/ion directions for prelinarimig an alloy for a very soft solder, uvumich timat journal says has time following very valuable properties. It attacimes itself very strongly, not only to metahihe siubstances, bust also to glass and pcrceiain; at a temperature em 700~ Fah. it is as soft as mu-ax, bust in ten or twelve huotsrs it hinecounes so hinam-di as to take a polish like 36 silver; and it imites metals so firmly that they may be worked in any manner whatever. As its bulk is not altere(l by its hardening, it fills perfectly any channels, crevices or joints into which it may be introduced. It is prepared as follows: Perfectly pure copper is procure(l, either by reducing the oxyd of copper by means of hydrogen or by preeij)itating the metal from the sulphate of copper with zinc turnings. Either 20, 80 or 36 parts of this pure copper, according to the llar(lness of the alloy (lesiredthe more the copper the harder the alloy is moistened thoroughly in a cast iron or porcelain mortar with concentrated sulphuric aci(l (at 1.85 (lensity); then to this metallic paste is a(l(kd 70 parts, l)y weight, of mercury; the mixture being constantly stiITe(l (hiring the addition of the mercury. When the copper is completely amalgam- ate(l, the composition is washed with an al)un(lance of h)oiling water to remove the sulphuric aci(l. The com- position, at first soft, becomes in ten or twelve hours so hard as to take a fine polish, and to scratch gold or tin. It may at any time be made as soft as wax by heating it to about 700~ Fali. or by triturating it in a mortar at a teml)erature of 260g. If, in this state it is l)laced between metallic surfaces free from oxygen, it ~vill unite theni so firmly that they may be wrought in any way without separating. SPIDERs. A learned entomologist, who has made a special stu(ly of the structure and habits of spiders, states that there is not a single authentic case on record of a person being killed, or seriously injured, by the bite of a spider; all the stories about the fatal bite of the famous tarentula being simply fables. These insects are, however, exceedingly ferocious in their fights with each other; their (luels invariably ending in the (leath of one of the combatants. In some species, the first step of the young as soon as they are hatched is to eat up their mother. ELECTRICITY AND SOME OF ITS PRACTICAL APPLICATIONS. ARTIcLE III. The construction of the electro-magnet, and its ap- plication to the telegraph, are fully treate(l in a number of works, but of late the application of clectro-magnetisni to the l)roduction of rotary motion or, indeed, of any useful mechanical effecthas re- ceived hut little attention, and we know of no ~vork which treats the subject in a thorough manner. A great number of magnetic motors have been in- vented, none of which have ever come into practical use in this country, although it is reporte(l thnt in France a few are in use for purposes requiring certain motions. All, or nearly all, the electro-magnetic machines constructed have made use of one or more of the fol- loxving powers: 1. The attraction of a coil or helix. 2. The alternate attraction and repulsion of opposite anul like poles. 3d. The attraction of an electro-ma~net for soft iron. Probably the first engine operated by the attraction of a coil was that of I)r. Page. The principle of this engine is as follows: A coil of insulated wire possesses powerful magnetic properties when a current passes through it, and if a coil be made in the shape of a tube or with a hollow cone, it will communicate mag- netic properties to a bar of soft iron placed within it, an(l if the current be sufficiently strong, the bar will be suspended without any material support. The cut ~ 2 represents a section of such an arrange- R meat. C C represents the coil, and B the suspended bar. If, while the bar is in this c ~ position, the current be stopped, the bar will instantly fidl out, and, when entirely without the coil, no attraction will take l)lace ; but if it be inserted part way, and the current then passed, it will be drawn wholly within. Thus, will be seen that, l)y alternately breaking time current and al lowing it to pass a reciprocating motion can be given to the bar, and, by means of a crank, a rotary motion may be conimnhmnicated to any appropriate machinery. Smmch a device, however, wommld only exert its power through half of the stroke; but by using two coils (Irawing alternately in opposite directions, a constant power may be exerted throughout the stroke. The cut represents a section of an imuproved device ~ invented by Dr. Page, in which a numn- her of coils are used, piled upon each other, and so arranged that, as soon as one coil has attracted the bar to its full extent, the current shall be transferred to the one next to it; and so on for half the stroke, when the current is to be transferred to the otimer side of the bar, when it will be attmacte(l in the opposite direction through the re- turn stroke. This beautiful device has as yet failed to come into general prac- tical use. The invention of machines which are operated by the alternate attraction and repulsion of opposite and like poles has cost an immense amount of time and money, but such machines are liable to difficulties which render them impracticable upon a large scale. Engines which are operated by the direct attraction of an electro-magnet for iron may be divided into two classesreciprocating and rotary. Reciprocating en- gines are entirely imiupracticable upon a large scale, for various reasons, the principal of which are: 1. The extremely small distance through which mna~netic attraction is exerted. 2. The waste of power by such an arrangement; and, 3. The large amount of friction to be overcome at each stroke. These objections refer chiefly to engines in which only two magnets are used. Such machines form a part of every well-appointed philosophical apparatus. IMPROVEMENTS IN PLATING SHIPS OF WAR WITH IRON. As the great interest in protecting naval vessels with shot-proof plates, which now prevails in Eng- land and France, is doubtless destined to be also felt in this country, we present the accompanying illus- tration from the London JJJechonicl ]Wigazome, as an in- dication of the present state of the art in England. These improvements have been invented by T. W. Plum, Esq., of Bk navon Iron Works, Monmouth, England, and of which the following is a description: For shielding ships and batteries on land or floating with thick metal armour plates, metal ribs are used with a flange or flanges through which they are to be bolted to the ship, battery, or other structure, and a dovetailed or Thead rib for holding the plates. The flang and dovetailed ribs a a b may be of the forms shown in the en~raving or of any similar form, so that there be a flang or flanges for bolting through, and a transverse head having more or less of dovetail shape, in order that when the plates, which are to be prepar- ed to fit the ribs, are inserted between two of such ribs, they will be securely held in their intended position; that the plates when fixed shall cover the bolt holes, and that the joint or joints of junction between the plates and ribs shall have a tendency to tighten when strpck. In preparing the ribs, except the first, to be fixed to any structiure, the bolt holes on one side of the flanges of the ribs are to be made longer, i.e., oval in form in the transverse direction of the rib, so as to admit of the second and successively fixed ribs being in the first place bolted through the elongated bolt holes far enough from the rib previously fixed, to al- low the plates to be inserted between theun without difficulty; and the rib to be then drawn by cramps or other known means tightly to the plate; the row of bolts on the other side of the rib are then put in and made fast. The upper and lower and vertical end ribs are made with one side only prepared to receive or hold plates. the other being rounded, moulded, or beveled off in any suitable shape, as at h. The space between the back of the plates and the face of the ship or other structure shown at c c c may line more or less according to the dimensions determined for the ribs and plates, and m& y be filled with any material that may be found most suitable. The Joint Action of Labor and Capital in Producing Wealth. If a man is cultivating corn with a hoe, the hoe is capital. It is the saving of previous labor, and it fa- cilitates his industrial operations, and these are the characteristics of capital. Nearly all active capital may be properly regarded as /0011 to work with. There is a regular gradation in implements from the simplest knife or ax up to the most complicated machine or the largest manufactory. There is no place in the ascend- ing scale where a line of distinction can be drawn, amid these imuplements are, in fact, essentially of the same characterthey are all tools in the hands of industry. There is capital, however, which cannot be regarded as of the nature of tools. Besides his hoes, plows, wagons, & c., a farmer must have food to eat and clothes to wear while raising his crops, and this food and clothing have been accumulated from previous la- bor, and are therefore capital ; thmey aid the operations of labor, and are therefore active capital. Men everywhere work with tools; consequently all wealth is the product of the joint operations of labor and capital. When Eve detemmined to sew some fig- leaves together, her first step was to procure a thorn or some other implement to work with, and that thorn was just as really capital as a Grever & Baker sewing machine, or the manuufactory in which those machines are muade. It is a curious fact that in the very first industrial operation of the human race, the first step was to procure the necessary capital. Shoeing of Cavalry Horses. The following circular has just been issued from the Horse Guards by the Adjutant General of the Britishu army. Sta It being very desirable that a uniform system (uf shociub should be established in the cavalry, and the whole of that important subject having been re- cently referred to the consideration of a Board compos- ed of officers of great experience in that branch of the service, assisted by two old and experienced professional men, the General Commanding in Chief has been pleased to direct that the following instructions, ex- tracted from their Report, and which embody the whole of their recommendations, be circulated throughout the cavalry, accompanied by duplicates of the pattern shoes, which have been sealed and de- posited at the office of Military Boards for general reference and guidance. 1. The shoe is to be beveled off, so as to leave a space and prevent pressure to the sole. 2. It is not to be grooved or fettered ; butt simply punched and the nails counter-sunk. 3. Calkin is to be applied to the hind shoe only, and is to be confined to the outside heel. The inside heel is to be thickened in proportion. 4. The weight of the shoes is to be from twelve to fifteen ounces, according to the size of the horse. 5. As a general principle, horses are to be shod with not less than six nails in the fore and seven in the hind shoe; nor is this shoe to be attached with not fewer than three nails out either side. 6. In preparing the foot for the shoe, as little as possible should be pared otut, and the operation should be confined to the removal of the exfoliatin~ parts of the sole only. 7. Both the fore and hind shoes are to be unade with a single clip at the toes. THE SCIENCE OF COMMON THINGS. NUMBER III. The food of all animals, with the exception of the small (luantity of COmnien salt which they cat, consists of organic l)roclllcts; that is, of matter which terms a l)art, or which has fornied a l)art, of either animals or vegetables. Organic substances are l)rincipally com- posed of four elementsoxygen, hydrogen, nitrogen anti carbon. A mans body, which weighs 150 lbs., contains about 7 lbs. of earthy matter, and the other 143 lbs. consist of the four Organic elements which I have named. Two of theseoxgen and hydrogenI have already (lescribed to you nitrogen forms about three-fourths of the air we breathe and with carbon you are familiar under several forms. Charcoal is almost wire carl)on, so is the diamoml black lead or ~dumbago is carbon with a little iron in it. Is there carbon in this piece of bread, father Yes. If you hold the bread very close to the fire, so as to scorch it, you will see the carbon all over the surface looking like charcoal. Why could we not see it before? You could but it had a different appearance. One of the most wonderful things in nature is the change which is wrought in the properties of substances by combining them together chemically. The air which we breathe is composed of oxygen and nitrogen mixed together mechanically. Let us have anothu ball to represent nitrogen an(l we can un(lerstand this matter perfectly. It must be made of some wood not quite as heavy as that which we used for the oxygen atom, for, though the nitrogen atom weighs fourteen times more than the atom of hydrogen, and the oxygen weighs only eight times more, the nitrogen atom is twice as huge as the oxygen, being of just the same size as the hydrogen. Let us make the nitrogen atom of a difterent shape so as to distinguish it readily. Now, the little round balls stand for the oxygen atoms, and the large triangular ones for the nitrogemi, and they are disposed thus in the air. A A A 0 0 7 V V A A A 0 0 0 V V V But if we combine them together chemically, thus one atom of nitrogen with live of oxygen (N. 05), how totally are their properties changed When mechani- cally mixed, they are in the gaseous form, invisible to the eye and impalpable to tIme touch except when in rapid motion. But when combined as represented, the atoms immediately come close together, they assume the liquid state, an(l become nitric acid. As atmo- spheric air, it is neessary tlmt we should be constantly passing fresh supl)hies through our lungs or we perish as nitric acid, a single teaspoonful taken into the bings would l)moduce instant death. lIme astonishing variety of substances produced by (liliererA chemical combina- tiomis of the four organic eleimments are illus~rated in the articles before you on time table. Comnbined in one way they produce the sugar, in another the butter, in others the tea, the coffee, the bread, the meat, the eggs, the milk, the l)el)I)er, & c. Tlmere are a few things, such as l)otash, that are not composed of the organic elements but with these few exceptions, everything derived from eltimer the animal or vegetable kingdom is formed by the combination of two or more of the sub- stancesoxygen, hydrogen nitrogen and earbon. They form oil, india-rubber, strychnine, chocolate, cider, wine, alcohol, lard, and the principal part of our clothes, shoes, hats, books, tables, floors, slmips and, in short, everything that is derived from eithmer animal or vege- table growth.

IN France every steam boiler is required by law to be furnished with a safety plug of fusible metal. It is composed of tin, 3 parts, lead, 2, bismuth, 4. A plug of this composition melts at a comparatively low heat. LESLIES IMPROVEMENTS IN IRON SHIPS. We find the following (lescription of this important invemation in the London illecheaies JJleyazome Mr. Andrew Leslie, of Hebburn Quay, Gateshead, iron shipbuilder, has patented an invention entitled, Improvements in the construction of iron ships or vessels, and for strengthening the same. Mr. Leslie thus descril)es his invention. My said invention relates to time construction of iron ships or vessels and to the strengthening of tIme same at those parts where time straimm is most felt by means of wroughmt iron, steel, em otimer metal box girder stringers or tubes, sucim box gimder stringel-s being placed on the top of time main spar or lower deck beams at time sides of time vessel, om placed under or between the main spar or lower deck beams at or near the center line of the vessel, or at time sides of tIme imatchmways. Time wlmole or any of these stringems may be continued tlmroughout tlme entire length of time vessel or extended along any part tlmereof, as nmay be de- sired. According to one mode of carrying out timis inven- tion, I l)~Ol)O5C first to secure a I)late, A, as shown in the engraving (wimiclm relireseusts part of a transvemse section of aim iron ship constructed according to my invention), on to time top of time beanms, B, of time vessel, this plate extending entirely round the vessel and serving as a base or foot plate upon whicim the wroughmt-iron box girder, C, is constructed. Timis box girder stringer extends along each side of time upper and lower decks, D and E (when two decks are used), and runs from stem to stern of time vessel or along any part of time length thereof. These box girder stringers, C C, are composed of wrought iron, steel, or other metal plates bolted, riveted, or welded together, and connected to each other and to time base plate by flanged plates or angle iron as simown. The base plate, A, may be made con- siderably wider timan the stringers so as to project inward toward time deck for time purpose of having the water-way bolted thereon, and the oustide plates of the stringers may be carried up some distance above time top of the same, as shown at F F, for time purpose of securing the stanchions tlmereto. G G are time middle or intermediate box stringers om- tubes also composed of wrought iron, steel, or other plates, and extending from stem to stern of time vessel or over any part of time lengtlm thereof, being secured to time beams, B. If found desirable these box girder stringers may be provided with suitable air valves in the top, hot- tomn, or side plates fom the purpose of ventilating the hold of the vessel, as it is found that time extension of the box girder stringers round time vessel admits of the gases, pro- duced by somne cam-gos, being readily collected and carried off. In Isis patent-specificatioms Mr. Leslie claims the application and use to and in the construction of iron ships and vessels of hollow box girders composed of wrought iron, steel, or other metal plates, for the pur- pose of strengthening the same, in the manner herein before described. - Fortunately for Mr. Leslie, his patent is dated 14th December 1859, abont two months pm-jar to the delivery at Liverpool of Mr. Fair- bairns lecture on iron ships, in which the distinguish- ed author strongly recommended the adoption of just such girders as Mr. Leslie has patented. 37 War Frigates and Gunboats. Russia, the third naval power of Europe, says an English exchange, intends not to be behindhand lint putting on her armnor, now that England has her lYe,-- Tiara and France her (Jlaimes. The Russian Admiral, Count Putiatine, left London recently for St. Peters- burg, taking within him, for imperial approval and rati- fication, the drawings and contract for an iron plated vessel of war, which is to be built forthwith on the Thames. The Paris correspondent of the London Times says that a gunboat of a new niodel passed through Toul- ouse a short time since on her passage from Bordeaux to Toulon, where she is to be prepared for sea. This boat is constructed on an entirely new model, of which the plan is said to have been given by time Emperor. She is composed of steel plates, and ~vill be propelled hy two screws set in motion by a mnaclmine of 14-horse power. She will carry but one piece of cannon. The boat is shaped like a tortoise. The mouth of the can- non will pass just over the back of the fish, which will present an imachined plane to the enemy, over which the balls will slide. The crew will be completely sheltered under this roof, of which the force of resistance is so well calculated that the heaviest shot or shell cannot injure it. It is said that several gunboats constructed on the same model will pass from Toulouse to Toulon. The first gunboat ready for sea is to go round to Havre, and thence up the Seine to Paris. NEW MODE OF YuLcANszmitG IKDmA-mujnazml.The Paris correspondent of the Photographic News states that india-rubber may be easily vulcanized by mixing it with sulphur and linypochiorite of lime. He says when flowers of sulphur and bleaching powder (hypochiorite of lime) are shaken together, a very strong odor of chloride of sulphur is immediately developed. If the mixture be somnewhat forcibly rubbed in a mom-tam-, ele- vation of temperature ensues, the sulphur softens, and the mixture becomes solid, while abundant vapors are evolved. When a much larger amount of sulphur than of the hypochiorite is used, and friction is avoid- ed when the two are blended, a mixture is obtained, which being added to india-rubber paste, either with or without the addition of chalk or oxyd of zinc, which serve to give body to the compound, vulcanization is effected either at the ordinary temperatures or by a mnoderate heat. By this means objects of any thick- ness may be vulcanized. ATamospinmEame FEmcrmamzzmss.M. Barral, of Pam-is, has lately made the discovery that main water contaimma minute quantities of phosphorus. He believes that it exists in the atmosphere in the form of phosphorated hydrogen, which escapes from decaying aninmal sub- stances. As phosphorus is necessary to the fertility of soils, we have in this discovery a key which unlocks the secret of summer fallowed lands becoming fer- tile. The anciemit Hebrews were accustomed to allow the land to rest without cultivation every few years. This was, no doubt, for the purpose of restoring it from comparative barrenness by cropping, to renewed fertility. It is now well known that ammonia also exists in rain water, and this is held to be the chief of fertilizing agents. Any worn out lands may be re- stored to fertility by allowing them seasons for repose, in the same manner that Moses provided for the per- petual fertility of the land of Israel. UsEs OF SOAPSTONETn Germany, soapstone or steatite is cut into pieces of any desired form, then placed in a crucible, heated to redness, and afterwards allowed to cool in a very gradual manner. Steatite, without having become hard or brittle by this opera- tion, has acquired sufficient consistency to permit of its being worked without any difficulty; and such is the facility of manufacturing it that it has found numer- ous applicationssuach as in the making of buttons, cameos and gas-burners. To give solidity and dura- bihity to articles made from steatite, in the manlier we have described, it is only necessary to expose them to a red heat for a few hours, when they become very hard. Articles made of steatite may be polished by the employment of emery, tripoli or oxyd of tin; and when impregnated within a solution of silver, and then subjected to ~ high temperature, they acquire a me- tallic lustem-.

Ilte sllceittl oroler of the evening, being the economy of utotive power for ftrnl btnlrhings, small manufac tories ttiiol sewing ma& hines, was taken up. Mr. J)IiIUEN l)resente(1 some csthnates upon the basis of a one-horse power, as the maximum probably in- tehl(leol to he enusidered. A steam engine of oneltorse power wonlol cost ttt lettst $300. The fuel would a ittomimit to lOIbs of eoil p~r Itoon, or 25 cents per dtiy. rile wear and tear and interest would amount to 7 cents per day. The steam engine being a dangerous macitille reoluires the attendance of a man of superior intelligence to a etoulinon laborer ; estimating his time at ~1. 50 IIOF clay. atni tlett one-sixtht of it would be coisumed in temmohing the engine, the cost of attend- thee ~votmlol boo 25 cents ier day. The total cost, there- h)re, is 57 ((hIts tt dtty ; wltich is very much less thlan the test of oloing the same work by manpower. In very mnatiy eases where work is done by hand, the steamot engine could be lisedi at a great profit, if it were not for the capital required in procuring tile engine. The first cost of tile air engine would be about double thttt of tie steam emigine. The itttcrest will therefore be doubled. For wetor amid tettr ttll(l itoterest Ite would ttlbow 12 cents a day. For fuel he woltl(l be liberal and allow the same as before, 25 cents a day. The cost of attemodatoce would be very much less, say one-twenti- eth part of to mans time, or 7 cents per clay. So that a safer and more easily muanaged power can be obtained from the ealuorie engine fo)r 44 cetlts per day. Another imower commonly used for agricultural purposes ts horse-power.

A horse will tiot host upon thle city cars more thlaml six or seven years. Besides, a nomnintol Ilorse power catluot be obtained from a horse either upbn the city cars or upon the farm for ten hours a day. Mr. IDmunEx It can from a horse lyhiell weighs 1,400 pommuds. Mr. BAneocIc proceeded to give estimates for the air engine, taking that of Wilcox as the basis. A 12-inch cylineler caloric engine now running in Westerly, II. I., crostiug $350, of at least four-fifths of a horse power, consumes only about 50 pounds of coal per dtoy, which would be but l2~ cents. And as it supersedes the stove before employed in heating the room, the actual cost for fuel is even less tItan this. Another simuilar engine, with an 18-inch cylinder, at Pawtucket, B. I., is doing more u-ork than two Itorses can do, at a cost not exceeding 15 cents per day for fuel. The wear amId tear will inlet probably exceed the same amount. Mr. FIShIER said that, according to Tredgold, horses cannot usually do muore thoon two-thirdls the work of a nomninal horse power for ten bmours a day. Stage pro- prietors say that they areobbiged to keep spare horses and to renew one-third of the whole number every year. The cost of a horse for interest and deteriora- tion nould be at least 20 cents per day. This will hring time animal horse power nearly up to the cost of tIle mechanical ilorse power. For the farmer who wants only a power for a week or two in the season, the Ilorse power would be more economical; but for mechanical purposes the horses must he taken care of, amid this is more disagreeable than to take care of a steam engine. In many shops no engineer is required to take care of the emlgine. As to safety, the low pressure emlgine, with a large safety valve, he consid- ered as safe as a caloric engine. A low pressure engimme wotuld cost more than a high pressure engine of the same power, perhaps 15 per cent more. Mr. STETSON remarked that the low pressure engines would be excluded from consideration for farm pur- poses on account of tile large amotmut of water required for condensing the steam. Mr. FISHER alluded to the success of agricultural steatu engines in England, there being twelve or thir- teen manumfactutrers of suell engines, with an inereas- lining demand. Mr. (mhuncmuuL considered tble comparison in Eng- hanoI between steam and horse power no criterion for thois country. Machinery there is cheap, and the cost of teen is much greater than here. Engines of about eight-horse power can be diril-etl about from farm to farm, ann do the work reqimirerl with economy and sitecess, and h)eyoud all competition. Mt. STETSON cousiolered the wear arod tear arod in- tem-ost utminderrtoteel by Mr. iDibben ill all his estimates. Time itintem-est alone noitlol amnoutnot to nearly as mucim as Ito hatl allolved for wear amool tear and interest. Another consitberatioro Ilas been overlooked. ThIe chances of boreakirog down are always considlerable with complex machinery. If the maclmincry breaks down in the city it can hoe at ommee reltaired, or the work can be immac- ditotely executed by solIlebody near by. But when we go bach into the country the resitlt of breaking down is timmunk tuore soriotus. If a steam engine breaks dowmo it tintay (tomtee a belay of suvermol weeks.

[Latingloter.] In the office of tile Boston Tieveler a rotary engimoc about as large as a half-bushel measure, fed by the Cochituate water, furnishes all the power that is required. But situa- tions like that must be extremely rare, especially in the cases embraced in the subject for discussion. The CHAIRMAN suggested the use of wihid as a motive power. Mr. FISmIER said that a small amount of wooter ex- posed over night would be cooled sufficierotly to be used again for condensation on the next day; so thtot where little power is required the low pressure engine would not require a very lat-ge sutpply of water. Mr. POOWELL thougllt that would depend upon the degree to which the water was to be cooled. If it is to be cooled down to 800 or 1000, it would take inmouclo more time to cool it; and if it is to be used when bult little below 200~, it Mould require from twemlty to forty times as much water to condense the steano. Mr. DInnEx, reverting to the amount of work a horse can perform, said tilat he hanl manle lois estitmmoote froni the actual performamice in hoisting stone. ~Ihoe average boorses in New York weigh about 1,100 pounds; but a horse weighing 1,400 pounds, such a Ilorse as may be seen upon thoc wagons of the safe men, can do the work of a Ilorse power. Mr. STETSON--Can we buy such a hoose for less tihooho $300? Mr. DIHHENNo, Sir. Mr. CmtuactIrLDinl the Ilorse lose its cotoditioio nuoder that labor? Mr. DInnExI do not know. Mr. CnundnILLThen that tells us nothoing of the work a horse can do. Mr. IDIBBEN mentioned the fact that the air emmgitoe or the steam engine could not be stopped tomid left to stand a week or two Mithiout damuger of imoj ury ; bntt the horse power can be mused at atiy tinie, totod left at any time, without any imijulmy, and witllout atoy par- ticular care. As to the air engine, if 44 cents per day uvas too mitch, lie should iihne to iiear another esti- mate. Mr. BABcocK estimated 15 cents for coal, 20 cemots for wear, tear; and interest, and 10 cents for care, amounting to 45 cents, for a two-horse emhgimoc, foumided upon the actual performance of the Wilcox engine in the Pawtucket btokery. A one-horse emingimoc would probably cost about 30 cents a day. TIle cheap- est power in use, he said, was water power. It is noore reliable than wiuld, and costs scarcely aumythoiuog. But it enon only be made available ml particultoo sitolto- tiemis. Wind mills could imot be made available, usu- ally, except upon the coast, where there is to sea breeze at certain times, and upon high hills. Mr. SEELY said that it would not do to settle tloe question merely by estimating the cost of the different kinds of power when in use, or the cost of tloc ula- chinery, for there are considerations which entirely outweigh the question of cost. No farniner could profitably use an engine that would cost from $300 to $600; for the labor that could be done with it would last but a very few days in each year. For the rest of the time there is only an occasional piece of work to be clone by poweran ax to grind, a little woodI to saw, or a little straw to cutand yet for these a power Mould lie handy if it did not cost too much. But el-cry farmer must have his horses, and tiocy will do this work. Probably for a farm of 100 notes or less, no air engine or steam engine woumld line to profitable purchase. Water can be used for power much more freqomently than it is. There are very few farms of 100 acres which have not a stream which comuld be made serviceable not a small expemise. Amid wind mills will atinswer for labior that oloes not requmire steadimless. If we coumlcl take tue power of the Mimid clutring the entire year arocl store it up to be useni as a constant force when required, it would be very use- ful. This might be done by employing time wiimd miii to drive water into an elevated reservoir, or in condensing air, or in Minding a spring, or ill 5OtinlO such way. Personally, he would prefer steam, or air, or water, to horse power ; and if either coimld be stub- stitminted for liomse power tip~inin a famm line silottId prefer it.

Mr. JOHNSON stated that Mr. Keminnish had a small rotary water engine, using six gallons of water per minute, under the Brooklyn pressure, and equal to ten-horse power. There is eighty feet head of water. 38 ~J5IW ~~dentifh~ ~rn~k~ut.

STEAM ExPANSiON. A correspomidemut, writimug umpon f-lie suibjeet of worhdmug steamus expansively, says both lmmurties mime right. Workumug stemum expaussively is ecomionsical in quick-acting engines, because the st-eam hums so little tune to condense ins flue cylinder. It is the comutramy in slow motion. This pertains ously to this omie if-em; f-here may be misamay other causes why scineusce mind practice do usot agree here. It uneest be re- uneusbered that steam is simply huarnessed electricity, uminiri thuaf it is the electricity that escapes, and not the lieumt alone, line a slow actionelectricity is the force. I shuall muout be responsible for this, however, as I knoiw nothing at mill mshmouut the stemim engine, and the sememice of thue dumy mi thiust direction. IF 100 parts of tolhouv (by wei~ht) are mixed with 25 of cuirbonate of soda, and heated to 360~ Fah. in a close boiler, a good soap will be foruned.

A new fact in the history of alummuinum consists iii its now being reduced, in the hands of the gold beater, in France, into leaves as tlsin as those of silver amiol gold. These results have been arrived at only with very great difficulty. The annealing of the alumminuns nuust be frequently repeated, and cannot be performed in the ordinary manner as with silver and gold. Other- wise, the operation of beating is conducted in the usual manner. A Pittsburgh cotemporary contains the followin~ sensible advice: The public are askina whether some method cannot be devised for warmino flue cars umpomi city railroads, and somuse suggest that stoves be placeol in thuem.

We are the advocates of peace, both foreign and domestic; but as war is Sometimesllnfortunately too oftenan inevitable necessity, we have, in accordance witit the spirit of the times, decided to pat the ScIEN- TIFIC AMERICAN, for one week at least, upon a war foot- ing, regretting, however, the necessity which obliges us to depart, even for so brief a period, from the ex- clusive discussion and elucidation of the beneficent topics for which this journal is altogether intended. Our present number shows that we have brought out the big gun, and that we have got upon the stocks iron plated frigates of war, soon to be in readiness for san- guinary conflict upon the high seas. We have not yet reached those last days spoken of by the good old prophet Isaiah, when the mountain of the Lords house shall be established in the top of the mountain, when He shall judge among the nations, and shall re- buke many people; and they shall beat their swords into plowshares, and their spears into pruning hooks; nation shall not lift up sword against nation, neither shall they learn war any more. For fifteen years past we have had extensive correspondence with mechanics and manufacturers throughout all the States, and we Itave yet to learn that the predictions of the inspired prophet have even an incipient realization on this or any other continent. We know not of an instance where a single rusty old sword has been beaten into a plowshare, but we have heard it announced that even the weather-beaten mus- kets of our distinguished fellow citizen, George Law, have at last found a ready sale. Amidst the general dullness of trade and finance, the forges of Mars are blazing away with unwonted fury, and even strange lire is iSStliIlg forth from their smoky embers. Dragons teetil have suddenly sprting up as armed men, and we can almost hear the shoitt, the shock, the groan of war. This, then, is the ugly side of the question, and before using our big gun to pour broad- sides from our iron frigates, we will stop to think the juatter over a little more seriously. The old adage says that, It is an ill wind that blows nobody good, and this is as true now as it ever was. If our readers suppose that the rumors of wars which now fill the country have destroyed eli trade, enterprise and business prospects, they are roundly mistaken. The printers of daily newspapers have all that they can possibly do to supply the im- mense editions for which the public anxiously calls. The want of a new invention by which papers can be more quickly thrown off was never more sensibly felt than to-day. We are told that the fire-arms and gun- powdcr mttiitltacturers are overcrowded with orders, hInd, in some instances, ate employing double sets of hands and running their works day and night. Colts great establishment, at Hartford, Conn., is said to be flourishing to an astonishing extent. We hear of the farming out from that concern to neighboring machine shops of one job involving forge work for seventy thotmsand arms. We are also told that the New Eng- land wagon manufacturers have received large orders for baggage and transportation wagons; this will also give employment to many. There is an immense de- mand, so we hear, for rubber clothing, coats, pants, boots, knapsacks, buckets, tents, blankets, spreads, and every coaceivable article reonired for field use. All the above goods are, at the present issue, cash articles. Several of the States have appropriated large sums, amounting to millions of dollars in the aggregate, for arms and munitions of war. Nearly all of this money will necessarily go to our mechanics and inventors, and keep thousands of them busy through the winter. The influx of money is very great at the present time. Nearly every steamer from Europe brings us half a million or a million. One steamer, the Persia, from Liverpool, arrived, a few days a0o, with three mil- lions. From California the regular supply is from one to two millions monthly. Meantime, at New York, there are, in our banks and savings institutions, $32,000,000 in specie on hand, and the prices of stocks have, of late, much advanced. Tennessee, North Carolina, Missouri, and some other State stocks, mmproved very sensibly since the 18th of Decem- ber. Illinois Central Railroad stocks, which stood, Dec. 7, at 51, sold January 3d for 79k, an advance of 28~i per cent. New York State 6 per cent stocks, New ~ still remain above par, the latest quotation bein~ 104. In reference to the cotton crop of the Southern States, we understand that the shipments from some of the seaports are very large. At the West, large orders for grain are reported, accompa- nied by the gold. Red Western wheat has risen within a short time, from $1.08 per bushel to $137~. The panic, or hard times, that our people passed through three winters ago appears to have had the effect of preparing them for a similar contingency in the future. We notice that the savings banks of the single state of Massachusetts, contain deposits to the amount of almost fifty millions of dollars. These de- posits are on interest, and consist, almost wholly, of the earnings of mechanics and other working classes. As the total population of that State is only 1,331,- 499 souls, it will be seen that the financial condition of that great mechanical and manufacturing State is extremely good. This desirable state of things doubt- less exists, in a proportionate de~ree, in many, if not all of the other States. By the recent treaty of peace, ratified between China and the Anglo-French allies, that immense empire is now at peace with the world. The previously signed treaty between China and the United States is therefore now brought into practical operation, thus opening to our people an immense and highly profitable market for all kinds of Ameri- can manufactures. The House of Representatives has lately passed a bill for the construction of two greet lines of railroadsa northern and a southern routefrom the JIississ~ppi river to the Pac~fic! It is expected that the bill will shortly pass the Setiate atid become a law. The construction of these railroads will form one of the most gigantic enterprises of the day, will give oc- cupation to hundreds of thousands of workmen and engineers, and will impart a permanent stimulus to every description of business. The Homestead Bill, which has just become the law of the land, gives every man aferni for almost nothisig, provided he will go West and cultivate it. We have thrown together these few items in order that our readers may see that, not- withstanding the political troubles which now brood over the country, our condition, in a financial and industrial point of view, is better than in 1857. With such abundant resources at command, and with our political difficulties composed, a thrill of joy would sweep over our whole land, and start into new life the wheels of commerce and manufacturing in- dustry. PROGRESS OF NAVAL ARCHITECTURE...NAPO. LEONS NEW IRON FRIGATE. It was said of Napoleon the Great, when he was an exile at St. Helena, that if some person were but to elevate his 01(1 grey coat upon a pole, in some corner of France, all the rest of Europe would quake. It is pretty much the same with his successor, the present emperor. All Europe watches every movement of Louis Napoleon with the most sensitive interest, and his prolific genius keeps all the nations of the Old World busy. No sooner does he adapt some new idea and commence to put it into practice, than John Bull straightway follows in his footsteps. This is especially the case with naval affairs, as it would never do to allow the French to surpass the English in mari- time efficiency. In nautical skill, and in all that con- cerns the manning aI~sd maneuvering of ships, England has long maintained a decided supQrioritv but with 41 that scientific grasp of intellect for which the ruler of France js distinnuished, he, sometime ago, concluded that it was perfectly possible to construct war ships, so invulnerable in their character, as to give them the same advantage over others more ably manned but less skillfully constructed, which a soldier, furnished with a coat of mail, has over a nude antagonist. In carrying out his ideas, he has produced La Gloire, a great war frigate covered with thick plates of steel, and perfectly proof against shells, and almost so against solid balls. As to the necessity of commercial nations adopting this entirely new system of building war vessels, we think there can be no question. Mr. H. Vivian, a member of Parliament, in writing to the London Times respecting the La Gloire, gives it as his opinion that the best wooden war ships are as useless in her presence as the old flint musket is before the Minhi rifle. Ten vessels of the same class are now building in French dockyards, so that England must endeavor to meet the issue of supremacy, when it comes, by equal, if not superior ships. In order to encounter such vessels ns the La Gloire on equal terms, two giant iron frigates are now being built in Great Britain, and these are intended to be very superior in steam power as well as general construction. One of these frigates, called the Warrior, is now building in London, and the other, called the Black Prince, by Napier & Co., at Glasgow. A corres- pondent, writing to us from Malone, N. Y gives a brief description of this latter vessel, which will be of general interest. He says: As you enter the yard of Messrs. Napier, the first object which attracts attention is a great iron framing resembling what we might fancy would be the skeleton of the Great Eastern. It is at present surrounded by a scaffolding, upo~t which several hundreds of workmen are busily engaged like bees around a hive. The Black Prince is to be 420 feet long; her breadth, 58 feet; depth, 42 feet. She is to be divided into eighteen watertight compartments, and two great Arlustrong rifled guns are appointed for each bulk- head. The bottom is constructed of plates 14 inches thick, and the sides lined with plates lths of an inch thick. Over this is to be laid teak wood planking, 1 foot thick; and the teak is to be covered with wrought iron plates, each l5~j feet long, 3 feet wide, and 4~ inches thick. All these iron plates are made in the best manner. They are tongued and grooved on the edges and ends, so that they fit most accurately into one another, and make watertight joints throughout the whole hull. All the iron plates are cut and punched close to the vessel, whereby the fitting of them is rendered very convenient. When completed, the Black Prince will be 10,000 tuns burden, and her screw engines, now being built by Penn & Co., of London, will be 1,250 horse-power. No person can have an adequate idea of the great size and strength of such a ship without actually be- holding it, but the account given will convey such an idea as will at once render it apparent that no wooden frigate could possibly compete with it. The conclusion at which our correspondent arrives respecting such an iron ship is reasonable. It appears to us that such a frigate could walk through an entire fleet of wooden war ships as easily as a life guards- man could cut his way through a regiment of paste- board soldiers. In addition to the above, we find some further information on the same subject in the London Engineer. It states that the entire shells of the Warrior and Black Prince are made of the best scrap iron, which has been found far superior to common rolled iron for resisting shot. The ribs which spring from the keels are 3 feet 8 inches apart, and are T-shaped beams; alid inside of these another set of iron beams run along the whole length at intervals of 5 feet, and all strengthened with enormous iron girders. The decks are to be covered with timber, supported on huge iron arches. The engines are to be so protected that no shot will be able to reach them, and the stem and stern nmay be completely riddled and yet the frigate will float.. When finished, each of these vessels will certainly be a leviathan of the deep. WHAT WE MOST NEED. Food and raiment are the chief of the material wants of man; if we have these wants fully satisfied, we should have necessity for little besides, at least for the physical man. Thus, tailors and cooks, who make the final preparation of the things we most need, seem to be the most worthy of the dignity and praise which are always denied them. If we consider a house with its appurtenances as a kind of mantle or overall for the family, we very readi- ly arrive at the conclusion that nearly all kinds of mechanical and chemical work have in view, directly or indirectly, the wants of the stomachs or skins of men. A steam engine grinds corn or weaves cloth, or if it builds a railroad or a ship, it is only to transport the corn and cloth to the consumer. The first inventions of men, of course, were such as ministered to their necessities or pressing wants. The 42 gar(ldn of L(len was so happily planted, and Adam was ~ perfect, tlmt all his wants, as soon as felt, were s disfied, and he had no use for an inventive faculty. Ilut a change caine, and the garment of fig leaves was invented all invention the first among menand the rude l)rototype of all the strangely fangled notions of tailors an(l milliners. When the human family in- creased beyond the narrow limits of a tropical climate, or perhaps in Eden, when winter came on, they in- vented for themselves more l)elfect garments from the bark of trees and the skins of animals. The arts of preserving food and building houses must have beemi very early learned, and the improvements in food and raiment must SOOli have cnlminate(l in the invention of roast heef awl breeches, which may still be received as symbols of our greatest l)erfection and of our exalt- ation above the brute creation. Many l)eoPle think that if they only had enough to eat and to wear, and at the same time had nothing to do, they would be happy. These are foolish people, for they do not understand how and why nature exacts hi or. It is only after labor that bread tastes sweetest, 1111(1 rannent is most becoming. Some of our paupers are practical illustrations of these do-nothings; they in- caliacitate themselves for labor by the practice of lazi- hess, and tile State gives them enough to eat and to w(ur, and they have nothing to (10 Iiesi(les the necessities of victuals, clothes and labor, there is perhaps a necessity of amusement or recreation for the senses; the ear needs music; the nose, fragrant o(Lors; the eye, gay colors ; tile tomlgile, 5pices, & e.

A New Instrument for Taking Horizontal and Vertical Angles. Mr. Abel Ware, of Athens, Maine, recently obfaimle(l letters patent Oil a new surveying instrimmellt, 0110 of which lie exhibited at our office a few days ago. As a Imiece of workmanship it is exquisitely fine, and the improvements which the patent secures appear to be of much importance in furnishing a cheap amid port- able initiumnemit, which are both desiderate to the l)ractical surveyor. Ihie object of the invention is the liroduetion of an instrunment which is adapted to the imicasurement of both vertical ansi horizontal angles, arl(l is much more simmilile iii its comistruction and less expemisive thami the theodohite, while it is capable of lielformaing the work of the transit and of the circum- Icrentor, though its cost does but slightly exceed that of either of these instrunmemits, thins meeting a long- filt miccessity for ami imistrumnemit which shall be cheap, coniliact, portable, and simificiemitly correct to supply the ordimmary requiremnents of the lamad surveyor in taking bothi vertical and horizontal angles. To effect this purpose, the several parts of this instrument are combined in such a mamimler thant by tIme use of but one gra(luate(l limmib or circle amid rotating vernier imlate or carriage with its sights or telescope, both hurl- zomital awl vertical amigies can be taken. The imivemitor will be haippy to give further informnation imi regard to his imistrimmusemits upon being addresse(l as above. AiswaeAzs AT SEvAsToror,. When this city was be- siege(l by sea ansi lamisi, a few years since, the Ilussians sunk a large fleet of war vessels in the river and har- bor, to prevent themmi falling imito the possession of the British and French, and also to render the river lmminavigal)le. After time Crimean war was concluded, our countrymami, (olomiel (iowan, made a contract with the ilussiami government to raise the sunkemi ves- sels amid clear the chiammel of the river. For several years lie has been engaged in fulfilling his contract, and has, by the latest news, rendered the river once more navigable. He employs daily about 200 men, who, with his clerks, & e., occupy tue naval arsenal, which was eomivsrtesl imito a renslezvous specially for thisma.

It is supposed that Colonel Gowans operatiomis will yet occupy two years. ROMANCE OF THE STEAM ENGINE. ARTICLE VI. SAvzluvsrmmps INDICATORSTEAM FmRE-EIeCINE. After the Marquis of Worcester, the next steani in- vemitor of prominence who appeared on the stage of time was Captain Thomas Savery, also an English- minian. This was about thirty years after the noble Marquis had been laid to rest at Ragland Castle. Very little is known of Savery as a man, but he published a pamphlet in which we have a record of his mechanical and inventive abilities. It is certain that he possessed considerable wealth and that he had acquired a thorough praetieal knowledge of mechanics. In 1718 no less a personage than the great Sir Isaac Newton made a report to the government on the praeticabihity of a maehiine invented by Savery for measuring a ships way at sea, wiiieh, from the description, appears to have been principally composed of a set of blades placed omi a vertleal spindle set down under a ships bottom, and which was revolved by the water. It communicated motion to an indicator through a train of gearing, like that of a gas meter. Captain Savery also constructed a fire-engine and exhibited it before King William, at Hampton Court, and the monarch was highly pleased with its performamice. At this pe- riod Newton was president of the. Royal Society, and mill matters of science and mechanics were treated be- foie that body with profound respect. To this insti- tution Captain Savery carried his imivention, and in its tiamisactiomis is a record of an experimemit masle with it before its members, imi their apartuiemit. It is stated to hiax c been quite successful, but we are miot left in doubt as to what the engine was, as the msccompamiying emigravimig ms a representatiomi of it, takemi from the primuted volummie of proceedings foi thie year 1699. In the hihistratiomi, k is a pipe which comidumets the steani frommi a boiler, left out of tue figuire to mender the exl)lanatiomi more clear. The steamii passes into two meceivems similar iii forni to metorts. A pipe, i, bramich- lug from each of these vessels is inserted into their bottoms; e e df are valves opening outward and pre- ventingby their actionthie return of any water that may have been fomced through them. A pipe, Is, proceeding from the cistern also branches to both re- ceivers, and is inserted into the top of each. Valves are placed at c c, by which a communication mnay be opened or shiut off with the boiler, alternately, accord- ingly as they mmiay be adjustedone being open when thie other is closed. Steam from the boiler being permitted to flow first into either of the receivers, the water which that re- ceiver contains is forced by the steam pressing upon its surface, up one of the branches of the pipe, i, and when the vessel is thus emptied ofthe water and filled with steam, the valve, c, is (hosed, and communication with the boiler mit ff. Cohsh water is thinen smuffereth to flow over the sumrfiice of thie vessel, which thins con- denses the steam within and forms a vacuum. The pressure of the atmosphere now forces water from a cistern or xvell below up the pipe, /s, into the empty vessel. At the instant~ steam was shut out from one receiver it was admitted into the other, by turning the other steam valve, and then the water was forced from it up the pipe, i, during the peTiod that conden- sation was being effected in the other vessel, and so on, as hias been described. In this manner, by the employment of two close vessels stamidimig in the sanie relatiomiship to omie another a5 the two cylinders of a common fire-engine, first by the pressure of steam and then by its condensation alternately in each ves- sel, a conmtant column of water was raised from a cis- tern and forced to an elevation proportionate to tue pressure of the steam. This was certainly a direct steam engine, and was recommended principally for raising water from mines. It would, and did, do thais, but not economically, although it exhibited much imi- genuity. Its inventor was rather despised than appre- elated by the owners of English mines, for whose bemi- efit it was chiefly designed. Subsequently he added several iniprovemnents to this engine, which will be il- lustrated in our next article on this subject, together with a further account of this very worthy invemitor. MECHANICS, ATTENTION~...TURNING TOOLS. The proper shape of a tool employed for turmilming metal can only be determined by experience, aided h~y a philosophical knowledge of the laws which gsmvermi motion. The relation of the curve or straight line to the ends desired to be attained must be as camefuhly considered as that of any motive agent whose aetiomi is correspondingly valuable to man. A tool which has merely a very sharp and hard edge will not accomn- plish the same useful results as one which is construct- ed upon philosophical principles, with respect to its shape and position. It would save a great deal of that. and expense in macblue shops if a more correct knowl- edge generally prevailed among those who foige tools, so that they mighit forni them as micarly right a5 pos- sible while the iron is hot. Much valumable timmie is wasted imi grinding dowmx tools to the pioper shape after forging, a great dal of n hichi tinie might be ecomioniized. If we consider the first pminciple of a euttimig tool, we shall fimid it to be that of the wedge, and thiat imi its performance it separates thie atoms counprisimig a whole by cleaving them asunder within mome or less force, as its shape is coirect or incorrect; but the way imi which the actiomi of thinat wedge is to be applied is the secret of the whole art of tool mnakiming. Speaking of tools, we do not in this connection recognize amy but roumghing tools. Let us suppose a round shaft to be in the lathie, and the tool applied to it ; the first consideration is whether the one in hand is such as to act within ecomio- niy, and produce good workmanship. The surface of the shaft is to be turned down one-fouith of an inch and it is a well known law that all revolvimig bodies throw off at a tangent within their circumferences what- ever is loosely attached to or detached from their sumr- faces. In obedience to this law, the object to be attainesl is to turn the surface of the iron so that its mefuse will run in a tangent. Now, supposing the tool to be moving laterally, as it does in operation ; if the edge be inclined at an angle of 450, the chip will first endeavor to pass off at a tamigent, but, as it nicets within resistance fiom the cuttimig edge amid the surface, it will deviate froni that direction, and, running dowmi the angle of 450, a corrugated and very brittle ciiip is produced. If we alter the edge of the tool so that its point reachines high above the centers of the lsthe, and set its angle sloping partially, instead of arbitrari- ly to the right, while its cleaving edge forms a tangemit (or nearly one) with thie circumferenee, the chip pro- duced will run off the tool in a true spiral, and vary but slightly from the pathi we claim it shinould travel. In the first mentioned instance, the tumning produced, although apparently even and true, is not and cannot be so evemi and perfect as that produced by the second tool set forth. The fmuct of the emitters being higii above the centers of the lathe prevemits the work froni rolling upon amid chattering it, as it is called. Moreover, by tesuing the heat of the two chips, pro- duced as described, as they leave tine tool, it will be founsl that the hmist-ninsntionecl is not so hotconic- quiemith the tool workish with less frictiomi on thie nietal, and thierefore hess power was mequmimed to duive the work. When we consider this fact, we directly re- cogminise its great valnie ; for, if we admit that omie in- strument is more economical of power than amiother we must admit that the freest working one will re- move more iron in a shorter space of time From uhi~ recognition, the pecuniary value of thine instrument be- comes evident. But in discussing the quality of tools which have keen edges and cut clean, we do not allude to faney tooL, made merely br exI)erilneut. It is l)ear them slowly aiid silently under the sharp cutting edges molly the l)raetical advantages to be (lerivecl from ~ of the tools, and thin shavings of the metal, which, as they are cut, coil up in long bright ringlets of iron, attest the experiment that makes it valuable by the form of the trenmendons power of these noiseless and all but omnipotent chip taken in working his lathe, we can, in some ~ machines. When the edges and surfaces are made perfect ly smooth, like the finest work of the cabinet maker, tIme nrc, jndgc of a craftsmans skill. l)lites are placed on an emid, gripped firmly by a mortising A revolution in the shape of cutting tools is gradu- machine, and, as they travel slowly backward and forward in our best machine shops ten years in the framework against a small tongue of steel, a groove ally taking place of about one inch in width and depth is formed, into which ago the rliamnond point was regarded as the neplos the corresponding projections formed on the side of an- c/be of roughing tools, but those now in mmse are very otlmer plate will fit with time most perfect accmmracy, time l)lates all being umade to dovetail on each of time fommr sides. ulitihremmt in slmape, mmd are (liftietmit to describe without _________________________ illmmstrntiomms. Mode of Spiking Cannon. Every mnan, of c(mmmrse, muakes his tools to suit him- From the ntmmnber of inqimiries which which have self, h)mmt as each handicraft is improved by individuals been put to us since Colonel Anderson spiked the e(mmnp(msing it, we ask time mLttelmti(mn of our workmnen to cammon at Charleston, as to the way spikiming is their cutting tools, and try what progress can be mnade done, we are led to believe that a large majority of in this dim ection. persons are ignorant of the process. To emulighten sue h, we have had the mmnexed views engraved to CAN WATER BE USED AS FUEL! illustrate the I)lans most usually adopted. Fig. 1 it is quite a comumon belief that water thrown on a liercely raging lire acts as freslm fmmel to the flamnes, and mnakes the fire hotter. A little consideration of the nature of water, an(l the laws of combtmstion, will ,homv thmt this belief is an error. Water, for nemmtrahizing heat, is far more efficiemut thu-nm any other substance. Ihirteen pounds of water, at 212 , in elmaging into steam, will practically ex- tinguish all the he:mt from the burning of a pound of coal a thermomneter placed in thue steam will not be raised mm single degree, althoumgh, in fact, heat enough is gemierate(l l)y the burning coal to melt nearly ten l)ounds of cast iron. Nothing will put out a fire 50 (111i(-k as mvater. limit it is saiul that water may be (lecomnpose(l when thrown on time fire, mund that theum it will bum-n this is nearly the truth. Ilue water may be decom- posemi, bunt not in such a way that the oxygen of the water can assist in the burning of its Imydrogen. rilme separation of the elements of water re(lmuires and con- sumnes a great beat the oxygen of the water eomnbines with its equivalent of carbomin, and so much carbon is, in effect, taken fromn the liie and produces no heat. When the water is thus decomposed, an equmivalent of hydrogen simnphy takes tIme place of its eqmmivalent of carbon, and gives omut in bmurmmimmg precisely the same amount of heat as is attalumble f mom the carbon. Of course, as hydrogen is a gas and carbon mu solid thue (lec-omposition of water in a cluarcoal fire would give a flame where otherwise tlmere would be none. Now, if these facts be pinut together, we arrive at time pimmetical concluisioum that if water be thurown on a lire, in the first place a gremint deal of heat will be consumed in comuverting thue water into stemmun and, in the second place, tluat if umminy of thue steam is decommuposed, thue hy- drogen set free will be at time expense of its equiva- lemut of carboun, and can, in bumming, produmee no more Imeat thmmn the carbon.

The Mechanism of the Horses Hoof. The hoof of a horse is considered as an epidermic ap- Ineudmugesimilar to nails and claws of 6tiuer animals, amid scales ot fishes, which are produced, mm the first instance, by the growth of cells, the contents of which grmmdualiy evaporate, so timat the walls of ths same gradually approximate each other. In the upper part of the hoofnear its matrix (nnother)these cells are to be observed; they are somewhat flattened against each other, but still retain a rounded form. The hoof, nails and scales, are not traversed by nutrient vessels nor absorbents, as is the case iii regard to the sensitive tissues; amid the flattened cells, when fully developed, vundergo but little change. The chemical analysis of the constituents of the hoof are as follows;- Cmnrbomm 32 limurts Hydrogen 7 Nitrogen 17 Oxygein amud sumlimhimir 14 Total 100 Ammmem-ccemu S/oe/c Jommi-imel.

MEssRs. EmToRs:Imn your issue of last week, youn say the mechuanical and nianufactuinring industry of the country is at a stamudstill. This is no doubt time case to a considerable extent, mome especially your avay, but much less this way. The factories are all quite busy in the City of Spindles, having just made up their accounts and de- clared good dividends (payable omi demnuamid), and mum-c bunying large imavoices of cottoun at mm low figume.

Ennious An inquiry is going the rounds in relation to the first railroad built in time United States. A locomotive ivas placed on the eastern pom- tioma of tine road frona Carbondale to Homnesdale, Pa, himemioums to 18.30 ; lint nvhaen tine road was hinnmilt, I uho mmot kmaonv. I wmus (here in time snumunnier mf that vean~. and saw tIme locomotive, whiclin had been taken off cia account of the road beimag so sleuidenly built. It ivas muot a passenger road A. H. Schnenevus, N. Y., Jam. 2, 1861. Ar the Augusta (Maine) bridge, a umovel manode of tmamusit for wimuter teams has beeni adopted. A track is lumid tIne entire lemugth of omne carriage way, and a large platform car placed thereon, so consuructed that a load- ed sled eamin be driven upon it amud easily dranvn over. rho object of this invention is to render type enses capable of being made more portable than hitherto, or of much less dimensions, so as to economize in space, and, consequently, in rent and artificial light, and, at the same time, exl)edite the work of the compositor. Type cascs constructed in the ordinary way require to be of such dimen~sions as to preclude the necessity of frequently sul)plying or rcl)lenishing the boxes with type, which would consurite considerable time. This arbitrary size occasions much embarrassment. The hand of the comilositor in the l)rosecution of his work necessarily travels over a great deal of space in a given time, and considerable artificial light is required to render visible all parts of the case. To obviate these (liftlculties, a type case is constructe(l of quite moderate thimensions, so far as area is concerned, but with the case and its boxes made quite deep, so that these l)oxes may hold a com~)aratively large quantity of type, the boxes being provided with movable bottoms, arranged so as to be readily adjusted or raised from time to time to conspensate for the gradual ex- haustion of the boxes, and keel) the type at the surface of the same. This invention was patented by Thos. N. Ptooker, of the New York Tribune office. APPARATUS roa ENLARGING PHOTOOttApILs. The object this invention is to obtain from photo- graphic negatives of a given size, positive pictures of a much larger size. The invention relates to the em- ltloyment of mirrors to reflect the direct rays of the sun through the camera containing the negative, and it consists in so applying and operating a system of minors or reflectors in combination with the camera, whereby, notwithstanding the movement of the earth upon its axis, the rays of light will continue to be reflected in the same direction for as long a time as may be necessary to obtain the print, and distortion of the picture be prevented. The credit of this in- vention is due to J. H. Whitley, of Owego, N. Y.

The most shrewd and far-sighted ruler of men now living is un(loubtedly the Emperor of the French. He seems to have anticipated every emergency that has yet arisen, and has always been prepared to meet it. Tie was the first who introduced rifled cannon into actual warfare on the battle field, and it has been ad- mitted that it was the terrible effectiveness of this weapon over the old smooth bore cannon which gained for him the battle of Solferino over an army numeri- cally greater than his own. One gre at cause of the success of the Emperor of France in most of his under- takings, is the superior judgment which he exercises and the resolute will with which he directs it. As an evidence of the consummate skill of the Emperor Napoleon in all matters affecting the military and naval glory of France, we refer our readers to a high- ly interesting article in this weeks number on iron war frigates. The government of Louis Napoleon never insulted French inventors by the passing of an ordinance prohibiting the purchase of patented inventions. Napo- leon himself is a generous patron of the arts, and he makes liberal provision for testing the efficiency of all inventions which relate to the national welfare. It has been state(l, over and over again, that the Armstrong gun was almost perfection itself, and that it had no equal. It has also been stated that it gave an immense superiority to British soldiers; but the late accounts which have been received from China of its efficacy (10 not sustain such conclusions. It appears that the lead bands around the iron balls sep- arated from the iron as soon as they left the muzzle and these played the mischief with some of their own outlying riflemen. The vent pieces of these guns are also said to be (lefective. The material of which cannon are made is a very important consi(leration. Steel is the strongest of all known metals, and yet cast iron, which is not one- fourth as strong, is the cc mmon metal which has been employed for this purpose. The tlifflcuilty of obtain- ing large sound castings of steel suitable for the pur- pose has no doubt been the cause of using an inferior metal; but by the invention of puddled steel all such ilifficulties may, we think, be obviated. The accom- panying engraving is a perspective view of a rifled steel cannona breech-loaderlately manufactured for the Russian government by Mr. Clay, of the Mer- sey Steel Works, Liverpool, England, and the London Mechanics ]Jfagazine, which contains t~ e illustration, states that he is about to make one or the United States government; it is therefore of no small interest to us. The breech-loading arrangement is effected as fol- lows :At the breech end, the gun is formed with a l)rojection, or extra depth, on its lower side, to allow for the borin~ out of a circular screw-threaded bore or recess of much larger diameter than the bore of the gun, and with its center considerably below the cen- ter of the bore. Into this recess is screwed a cylin- drical screw-threaded block or breech-piece, B, which closes the bore of the piece when screwed home, but which has formed through it a cylindrical passage so placed that when the breech-piece is turned back through a portion of a revolution, this passage comes directly opposite to the bore of the piece, and allows of the charge being passed into the barrel. In the engraving, the breech-piece is shown in such a posi- tion that the charge may pass freely into the barrel; when this has been done, by turning the handle (shown on the breech-piece) partly round, the hole in the breech-piece will be moved away from the bore of the gun, and the latter thus effectually closed. On a close inspection of the engraving, it will be seen that a pin is inserted at the upper right hand end of the gun; this forms a stop for the handle to come against, and may be removed by loosening a thumb screw that nips it, when it is desired to screw the breech-piece en- tirely out of place for cleaning the parts. The carriage on which the gun is shown mounted is also made from Mersey steel, and has excited a good deal of admiration. The gun is supported by its trun- nions (which are formed in one with a hoop shrunk on the gun) upon a strong bracket, which is pivoted upon the top of the carriage, and has a tail piece that extends backward, and is supported upon a box brack- et fixed on the carriage near the top. In the extremity of the tail-piece is formed a slot through which rises the point of a nut or bolt, the head of which (which is within the box bracket) receives a transverse screw worked by a hand wheel. As this wheel is turned, the gun is traversed with the greatest nicety. The elevating screw is placed above the tail piece, passing into a hand nut below, and carrying a bracket above in which the breech of the gun rests. The range and accuracy of fire of a gun depend in no degree upon any given form of breech-loading de- vice, itut a good breech-loading arrangement may prove very beneficial, viz., by increasing the rapidity of fire obtainable. This gun has been discharged no less than nineteen times per minute, and in this high rate of discharge it is incomparably superior 1)0th to the Armstrong and Whitworth breech-loading arrange- ments. HEWITTS PROJECTILE. Mr. William Hewitt, of Bristol, England, has in- vented a method of dispensing with rifling cannons, and at the same time securing long range and unerr- ing accuracy of flight. The particulars of the inven- tion, as stated by Mr. Hewitt, are as follows: 1. The breech is bored, say one-eighth of an inch larger than the bore of the gun, the projectile, which is elongated, being constructed to fit the breech. 2. The projectile to be coated with a soft metal, with a hole through the center from end to end (see the drawing). 3. Immediately the projectile enters the gun it meets with a shoulder which takes off a shaving, thus molding it to the exact size of the gun, thereby precluding all windage. 4. Immediately the projectile leaves the gun the air forces out the bevel plug at the back (on the drawing) the air, then, having a free passage through the projectile, prevents the possibili- ty of its diverging either left or right, or turning over; on the contrary, it causes it to travel with astonishing and un- erring precision; the sudden expansion of the air at the back~considerably assists its onward course. AMERIcAN RIFLED CANNONDuring the hait summer a board ot ordnance and artillery officers, belonging to the United States army, were engaged in making ex- periments with rifled cannon, and the results obtained left no doubt upon their minds as to the superiority of rifled cannon over plain, smooth bores. A report was made by them to the Secretary of War, recommend- ing elongated and expanding projectiles. Arrange- ments have been made for grooving a portion of our army cannon. COAL OIL GAS ExpLosIoNOn the 31st ult., an ex- plosion took place at New Bedford, Mass., in a mann- factory for refining Pennsylvania petroleum oil. The apartment became saturated with gas from the oil, mixed with air, and the touch of a match by one of the workmen caused it to explode in an instant. The force of the explosion was felt at a distance of six miles. OF THE SCIENTIFIC AMERICAN. THE BEST MECHANICAL PAPER IN THE WORLD. SEVENTEENTH YEAR! VOLUME IYNEW SERIES.

Ihe blast furnace is alternately charged with coke, ironstone and limestone, in proportions depemudimig upon the quality or - nimmumhier (if iron desired. The arrangement of these mumaterials in the furnace is gener- ally deemed important, tlmoumghu it admits of consider- able latitude withiomut ammy ahihureciable alteration in the working of the furnace.

The working (if flue fumrmmaces thmemuiselves seemums to shuow that an open- doubt, is one source of the variety of opinion enter- taimmed in various distmicts as to the advantage of taking off the gas. The writers expeinience at Middlesborough has been flint time waste gases can be taken off without affecting the quality of the iron produced, though at the expense of more fuel. The mode of closimig flue funinuace top and taking off the gas at the writers works is showmin in Fig. 1. The top of the furnace is closed hmy a light circular wrought iron valve, A, six feet six inches diameter, with sides tapering slightly outward from below, to admit of being easily drawn up through time materials, which are tipped at each charge into the external space, B. To prevent excessive wear upon the body of the valve, shield plates are attached at four points of the circumference, against which the material strikes as it rolls out of the harrows. An annular chamber, C, encircles the throat, triangular in section, into which the gas pours through the eight orifices, D D, from the interior of the furnace, and thence passes along the rectangular tube, E, into the chamber, F. At the extremity of the tube, E, is placed an ordinary flap valve opened by a chain, by means of which the communication between the furnace and the descend- lug gas main, 0-, may be closed. The valve, A, is par- tially counterpoised by the balance weight at time other extremity of the lever, H, and is opened by a winch, I, when the space, B, is sufficiently full of materhais. At the time when the blast is shut off for tapping the finmraace, the gas escapes direct into the atmosphere throuugh the ventilating tube, K, which is connected hiy levers, L, within the blast inlet valve below. The waste gases pass from the furnace top to the hot blast stoves to 1)0 heated by the waste gases down the (le5Cendin~ main, (1, Figs. 1 and 2, into the horizontal main, M, Fig. 2, running parallel and close to the line of stove, N, fr om which descend smaller pipes, 0, to each stove. The supply of air for burning the gas in the stoves is admitted through the three tubes, P, and can be re~nlated at pleasure by the circular slide closing the ends of the tubes, which has an aperture corresponding to each tube, an(I is planed on the 1~nlA)ing face, as is also the surface against which it works, in or(l(~l that the slide may be sufficiently air- tight wheft closed. The ignition takes place where the air and gas meet the imiteil gas streaming into the stove and (liffusing it.s heat uniformly over the inte- rior. An important element in the working of an apparatus of this (lescription is to provi(le for explo- sions, which must take place if a mixture of gas an(l air in certain proportions is ignited. To provide for this c~ptingency, escape valves, Ii, are placed at the ends and along the tops of the main tubes, G M; but to prevent explosions as far as l)Ossil)le, the ventilating tnl)e, K, Fig. 1, is used at the top of the furnace, con- nected with the blast valve at the bottom, so that, when the valve is closed, as at casting time, the act of (losing opens the ventilating tube an(l allows the gas to pass away (lirect into the atmosphere. The gas woul(l otherwise be in (laliger of slowly mixing with air passing back through the stoves or otherwise gain- ing access into the tubes, and would thus give rise to an explosion; until the ventilating tube was provi(le(l, it was necessary to lift the valve, A, closing the mouth of the furnace when the blast was taken off, otherwise slight explosions took l)lace fiom time to time. [a the use of 1)nrham cokes in the l)last furnace an inconvenience arises from the large deposit which t~kes place in the passage of the gas from the fmunace and in the stoves an(l boilers. lTn(ler the boilers this deposit is a great objection, as it is a very bad conductor of heat, awl necils to l)e frequently removed; in the stows it is not so objectionable, though these need a perio(lical cleansing. The (leposit (hoes not arise alto- gether from the cokes, it is true; and it may be inter- estim to know its composition, which is as follows: Silica 1886 Carbon 1614 Alumina 1387 Sulphate of liume 1361 Lime 1101 1~rotoxyd of zinc 1031 Peroxyd of iron P01 Protoxyd of manganese 236 Potash ~11 Protoxide of iron 123 Manesia 125 luloriile of sodiurs 006 10000 At a tomperatmne of upwards of 3,0000 this mixtnre melts in a yellowish slag, (hispehling the zinc; but there are no signs of fusion at the temperature produce(l by time ignition of the ~as in the stoves, which mnst roughly approximate to that of melting iron from the results of a few experiments made to ascertain this point; though thin pieces of cast irrs~ were not fairly melted (lown, they reach the rotten temperature, which is only a few ule~rees below melting, and gave further signs of nearly melting by throwing oft sparks when (julickly withdrawn from the stoves and struck smartly against another object. The writer has heard it asserted that the closing of the top of the furnace is the sonree of mischief to its working imy producina a back pressure in it. Under ordinary circumstances, with the furnace top open, the blast enters the tuyeres at a pressure ranging from 21 to 3 lbs. per square inch. In the present close-topped furnace there are eight outlet orifices, D, Fig. 1, each two feet by one foot, giving a total area of 15 square feet for the passage of between 5,000 and 6,000 cubic feet of gas per minute raised to a temperature of 4500 Fah.; and the actual luack pressure of the gas, as measured by a water gage inserted into the closed top of furnace, is from 1 to d 2 8 inch column of water, or al)out 1-40th or 1-50th of a pound per square inch, an amount so trivial as com- pared with a pressure of from 2~- to 3 lbs. as to be inmworlhy of notice. Of course, if the tubes are con- tracte(l in size a greater back pressure will be produced; and it is quite possible that, where attention has not been paid to the circumstance, the back pressure may have interfered with the working of the furnace by preventing the blast entering so freely. As regards economy in the wear and tear of hot blast staves of the or(hinary construction there can be no question ; the pipes last much longer when heated by gas, provided the temperature of the stove be carefully watched to prevent its rising too high; whilst the value of the same heating surface, compared with its value when coals are used, is greatly increased, owing t( the uniform distribution of the ignited gases through- out the stove. In the use of the gases at the writers works, this economy of surface is such that two stoves heated by gas will do the work of a little more than three heated by coal fires. The Eureka Lake Ditch. California is not only one of time most wonderful coimtries in the world with respect to its natural re- sources, but also as it regards the enterprizing spirit of its citizens. An amount of original engineering genius, at once comprehensive, bold and wise has lucen exhibited in the construction of hydraulic works for conduetlug water from great distances to the mines, which places her nearly on a level with the heroic old Ilomans, whose ancient aqueducts still excite our wonder. The folhowin~, from the San Francisco Bul- letin, is an account of one of the California hydraulic enterl)rizes to which we refer: The Eureka Lake Ditch is one of the most remarka- ble enterprizes in the interior of our State (Nevada county), which, from a very small berinnin__ has gradually grown into gigantic proportions, an(l, al- though before its completion but little known, must be destined to attract a goo(l deal of attention now that it is finished. It traverses the entire extensive region, rich in gold, lying between tIme Middle and South Yabas, from the summit of time Sierrawhere it is fed by a number of larger and smaller lakes down to the junction of these two na ei~ nmai the French corral, a trunk of 60 miles, but formnm~ ~x ith its branches to all huportant mining l)lac( s adjacent, a total of 250 miles of ditch. Throughout tins eVen- sive region, the hydraulic methoui of mmnin~ psedomi- nates which employs water power as a 1 sbomm~ agent. The call for water is, therefore, enormous, and likely to remain so for a generation, as the mines ase cry rich, an(l notwithstanding the numesous dasms now worired, yet not more than a commencement may be said to have been made. The Eureka Lake Ditch Company controls nearly all the water in the district described, and have more of it than thmeir puesent works can carry ; yet they will never be able to satisfy all the present or future ule- mand for it. The whole of this auriferous region is, therefore, entirely dependlent on the ditch. For near- ly six months the same is supphicd by rivers, creeks an(I some of the lower lakes. During the balance of time year, it receives its water frons some large lakes embedded near tIme summit of the Sierra, among al- most eternal snows. The largest of these lakes alone furnishes about 5,000 inches of water (lailv (hiring four months. The enterprize was started in 1858, by a company of ten Frenchmen of great intelligence, almost without means, who secured thine necessary water riglmts awl karl them duly recordemi at Nevada. Their tenure of the same found a guarantee in the law which secures to the miner the possession of his claim, and which has been recognized in this State by the Supreme Court. These water rights could at any moment be sohd to other ditch companies for a large sum, and are stated to be really worth not fir from 1,000,000. In 1854S a small ditch was completed to Eureka South, where the entrepreneurs united their interest with those of the Miners Ditch Company, then already in existence, and in the hands of an intelligent American company and management. A duly incorporated as- sociation was then organized, under the name of the Eureka Lake Water Ditch Company. The Miners ditch had been in want of water, which the Eureka possessedthe latter lacking, in turn, means to carry on tlmeir work as fast as was desirable to the rich mines lower down. In their union, both companies found relief. The sales of water furnished the means for further extension and perfection of the ditch, whmich, to a great extent, may be said to have been built out of its own resources ; and, in its present finished state, is a gigantic enterprize, commanding the greatest ad- miration. The entire worksditches, fimnes, aqueducts, pipes, re, i-voirs, & c.are stated to have cost about $950,- 000, toward which the work itself has paid about $750,000. Since April last, tIme weekly cash receipts have averaged, we are informed, about $6,000. The annual income is at present 300,000, for water is sold in whiter also. The monthmly expenses of the cons- pany for preserviimg the whole property in the best of condition amount to abSut $3,000, including the ad- ministration. The amount of water sold daily is about 6,000 inches, at 16 cents, while, we are inform- ed, most companies in California charge from 25 to 50 cents per inch. The company is just now occnpie(l in enlarging the main (trunk) ditch, audI making sdim other important unprovements which n ill mci ease thum amount of water they can delia-er. By omn~ to for- flier expenses, in increasing the capacmt~ of some of the ditches, flumes audI dams, the weekl~ in eceupts could easily be raised to 810 000, without exceedmn~ SoO 000 extra outlay. There are about 40 reservoirs, which cost from $3,000 to 86,000 each. The iron pipes, 22 inches in diame 1cm, which carry the water through San maim from one hill to another, cost 812,000. An aqueduct, named the ~ Magenta Flume, between Illoomfield and Eureka, was built at a considerable expense, and is as substantial as it is beautifula work of art, and a wonder to behold. The above infonuation we owe to lnarties intonate ly acquainted with the enterprize, wlmiclm illustrates how much may be accomplished wills scanty meammi andl energy in a country like California. The small number who originated andl acconaplished this stupen- dous work form still its priuaci pal slmarehmolders. They have for years seen no return for their labor, and have at times been conspelled to pay crushing rates of interest ; still, they have mostly preserved their shares, and are about to reap a rich harvest.

This sand inns time appearance of fine steel filings, and if a magnet be dropped upon it audI taken imp again, the instrumment will be found thaickly coated with the iron granules. The Australiams JFail gives a lengthy account of it. It states that the place where time sand aboummads is alona the base of Mount Egmont., ama extinct volcauso, amid the deposit extends several miles along the coast, to the deistls of main- feet, and having a corresponding breadtha. The geological supposition is that this grams- uulated metal has been thrown out of time volcano, alomig flue base of which it rests, into tIme sea, anrl there pul- verized. Time qumantify is so large that people omit there looked upon it as utterly valmueless. Captain Moishead, a gentleman iii the West of England, was so muds inipressed with its value that he went t.o New Zealand to verify the reports made to him, amad was fortunate enouioh to find tlmem all correct. He smelted the ore first in a crucible, amid suil)sequently in a fur- nace ; the results were so satisfactory that lie immedi- ately ol)tained time necessary grant of flue sand fronm the government, and returned to England withs several tumns for more conclusive experiments.

Taking the sand as if lies on the beach and smelting it, the pro- duce is 61 per cent of iron of the s-cry finest quality. And, again, if fIsk samad be subjected to the cemenfa- floss process, the result is a tough first-class steel. whaicla, in its properties, seems to suirpass any other de- scription of tlsat ussetal at present kisowis. The haves- tigations of usetalhuirgical science have found tlsat if titanium is mixed with iron, the character of the steel is materially improved ; but, titamaiuumas being a scarce ore, such a mixture is too expensive for ordinary pur- hoses.

There is one muscle round the mouth to close it. There are delicate little muscles that move the eyelids, and the heart is a muscle, or set of muscles, which, by their contractions, drive the blood through the arteries, all over the system. What is the use of fat It performs several offices. One is to round out the system awl complete the l)e~u(ty of the perso1~. Your cousin Janes smooth neck OWC5 its beauty to the skill- fid manner in which the adipose matter is l)acked into all the crevices between the muscles, veins aud arteries. For Nature expends no small amount of labor in the pro(luction of beauty. Behold the lilies of the field, not Solomon in all his glory was arrayed like one of these. Another use of the adipose matter is to serve as a reservoir of aliment for the support of the system. In the fever which I recently had, my stomach was in such a state that it could digest no fond and, by one of those beautiful adjustments so common in nature, my appetite rejected it, and I did not eat a mouthful for several days. The consequence was that the heat of the l)ody had to be kept up by burn- ing the fat in the system, and how rapidly this was consluncli I 5ll~~O5C I lost 20 pounds in the course of three (lays. Hibernating animals, that sleep through the winter, are generally as fat ns they can be when they crawl into their nests in the Fall. Their thick furs prevent the radiation of heat, so that little is re- qlure(l to be generated; their breathing and circulation are sluggish, causing a slow consinuption of matter, an(l this matter is supplied by the store of fat in the system, which is slowly l)urned up during the winter, and the animals come out in the Spring as lank as Pharaohs lean kine. If you put a piece of fat on the fire, you see that it burns with a blaze. Whenever any organic substance lIurns with a blaze you may be almost sure that it contains hydrogen. The burning of a sub- stance is simply its combination with oxygen. When- ever an organic sullstance containing hydrogen is suf- ficiently heated, it is decomposed, and, as the hydrogen is separated from the other elements, it takes the gaseous form. Rising in this hot state, as it comes in (ontact with the oxygen of the air, it combines with it in other words, burns; one atom of oxygen combining with one atom of hydrogen, and producing water (HO). There is phosphorus in the bones which, when separ- ated, will burn with a flame, but almost invariably when you see any animal or vegetable substance burn- ing with a blazethe flame of a lamp, of a kitchen fire, of a burning buildingit is hydrogen in the act of com- bining with oxygen, llroducing water. On the other hand, when you see an~~ organic sul)stance burning with a re(l heat, without blaze, like charcoal or anthra- cite coal, it is carbon combining with oxygen and ~)ro(hlcing, generally, carbonic aci(l. If the blaze pro- (11WC5 a goo(l heal of light, you may be pretty sure that the substance contains both carbon and hydrogen; the light coming principally from the intensely heated carbon before it is burned. Tmini: WArcn OF GENERAL WASHINGTONWe were shown yesterday, says the Louisville Journal, a gold watch of the olden time, which is of great value as a memento of an huportant event in American history. rile watch was a present from Gen.

Lord Corawalliss capitu- lation, Yorktown, December 17, 1781. The watch is of London manufacture, and was made in 1769. It is said that the watch was taken to San Francisco from Paris by a Frenchman, who became embarrassed there and sold it to tile present owner for the sum of fifty (lollars. ROMANCE OF THE STEAM ENGINE. ARTICLE VII. 5AvEavcoxTrxuan. In tile early part of the seventeenth century, Eng land had acquired a high position in metallurgy. This was due to her coal resources, as it was even then well known that there was more coal beneath the surface of that island than there was in France, Germany and Sweden. Her iron manufacturers, however, came to a stand still about 1700, owing to the great expense of working her deep coal mines, which really contained the best and greatest amount of this fuel. Horse- power was then generally used for pumping up the water and raising tile coals. This answered very well for shallow mines, but as these were worked out, the value of coal lands began to deteriorate, owing to the difficulty of boring and working the deep mines. At this period the whole country was incited to look for some new invention that would work these mines. This is the reason why the early steam inventors in England devoted special attention to tile application of their engines for pumping water from the deep pits, and Captain Savery was among the most in- genious of these earl) steam engineers. The accompanying figure represents the direct steam engine of Captain Savery, of which he said, in a pamphlet called The Miners Friend published in London in 1702): Its power is in a manner infinite and unlimite(l, and will draw you water five hundred or a thousand feet high, were any pit so deep. . I dare undertake that this engine will laise you as much water for eightpence as will cost you a shilling to raise the like with your old engine, the which is tilirty-three pounds, six shillings and eightpence saved out of every hundred pounds; a brave estate gained in one year out of such great works, where as much as eight thousand pounds are expended per annum for clearing mines of water only, besides tile expense for repairs of gins, engines, and for horses, & c. Thus, Savery calculated the advantages of his engine, and he said that, for one hundred years previous to his inven- tion, no imllrllvemeilt had been adopted in workhg ft the English mines. This engine has two U iler fires, a; one boiler, L, is larger than the other; b is the fur- nace of one, and c is the general chimney. Tile small pipe, g, reaches nearly to the bottom of the boiler. The other pipe, a, of greater size, is inserte(l into the same depth, and has a clack valve in it above the boiler top, opening upwards; this pipe, a, passes into the large boiler; o o are steam pipes; one end of each is inserted into the root of the large boiler, L, and the other end of each into one of the receivers, o P. In this manner comniunication is formed between each of those vessels and the boilers; q q arc screws by which CONSIDERABLE interest has been manifested in New York in regard to an invoice of Permmvian cotton re- cently received via Panama. We understand that it is ilart of a shipmemlt of fifteen himudred bales, most of which was consigned to Europe. The quality is very beautifinmi, and the sample shown would sell readily at fifteen cents, even in the present state of the market. The plant from which it is taken is said to he a peren- nial shrub in Perim, indigenous to the soil, the growth of which already extends over a considerable tract of water pipes are fastemled together.

P p to lnake water flow over themli to condense the steamn inside; a z are Imandles of tile regulators. Jibe boilers, we will suppose. are filled with water to the necessary bight; all the cocks are sllut; the valves are in position, and the receivers empty. A fire is now first placed under the larger boiler, and steam is raised to such a pressure as will balance a column of water equal to tile lli~ht bet~veen the bottom of the vessels P p an(l tile upper surface of the cistern to which tIle water is to be raised through pipe, v. By turning tIle handle, a, of one regulator, it opens a communication between the vessel, p and the boiler; all the amr s timen expelled tlmrougll the valve, r, into pipe, S. Tile ilandle of the regulator is now turned, and the steam fromn the boiler is cut off IvIlen tile vessel, p is full of steam. Water is now made to flow over its surface by pipe, p from the cistern, a. This condenses time steamn, forming a vacunimi inside, wllen the water from tIlE mine imllmuediately rises tinough pipe, t, into the re- ceiver and fills it. Time valves, a, are now closed so tllat no water can ascend from the mine, and then steam is admitted by tile regulator into tile to1) of tile receiver, p again, when the water is forced upwards through p s into the elevated cistern. Time same oper- aticIlls take place with tile other vessel, P and so Oil continimally, thus raising a steady columun of water by the alternate actiolls of steam an(l commdensation in the two vessels, P p. In order that the large boiler should be kept COIl- finually working, Savery used tile small boiler, d, to feed the large one through pipe, a. The small boiler was kept closed, and when its pressure exceeded tllat of the large boiler the water of the former was forced into tIle latter by the pipe, a, to replenish it at inter- vals. The smuall boiler was fed at intervals with cold water through pipe, e, wilich received it froum the dis- charging water pipe, s. This was certainly a most in- genloims and direct boiler feeder. The cistern a, I vhich furnished water for condensation, was also simpplied wmth water from pipe, s. All tile clack valves in tile pipes openeEl upwards. Such is a descriptiomi of tile construction, arrange- muent and operation of Savery s celebrated (ngine, called a fire engine: and it was certainly more entitled to the name of caloric engine than any hot air motor of more modern times. Smich an emlgine is of commrse out of the question at the present day, but it affords us evidence that he possessed an invemitive mind of a very higll order. He stated that it would he very useful for pumuping water ilItO an elevated reservoir,from which it could be taken to drive a water wheela mode of driving macllinery by water power whicil has been pro- posed to us several times within a very few years. Savery obtained a patent for imis engine in 1698, at whicll period he imad really erected several of then), and they had operated very successfully in companisomi with that of the Marquis of Worcester and othcrs that had preceded themn. A very curious incident is related regarding the way Saverys mind was first directed to steam emgineering, and it shows that, in one instance at least a tobacco pipe afforded a lesson of inspiration. Switzer says: This gentlemans thoughts (Saverys) were always employed in hydrostatics or imydraulics, or in the im- provenlemit of water works; and the first hint wllich, it is said, he took his engine from was a tobacco pi~)(, wilich he imnmersed in water for the purpose of wash- ing it. He discovered, by the rarification of tile air in the hot pipe, that the water was made to spring through its tube in a wonderful manner. SEPARATION OF BISMUTH FROM LEADTile Annales des Mines states that, in some of tile mines of Germany, the ore of lead contains a small quantity of Ilismutil, which concemitrates in the pig lead. Towards the en(I of the cupellation there forms a green litharge, very rich in bismuth. Tills 15 gathered separately, redinmced, and tile alloy of lead and bismuth is cupelled. There remains some bismuth, which is placed in another furnace and heated until it sparkles (cc qee lephfaomene de leclair ail lieu). In an essay on a large scale, 50 quintals of green litharge were reduced. The alloy contained 54.5 of bismuth and 65.5 of lead. Time his- ninth extracted contained only traces of lead and of iron, and 0.42 per cent of silver. ELECTRICITY AND SO1~IE OF ITS PRACTICAL APPLICATIONS. ARTICLE IX.

As the armaturcs must aecessarily be at si}mo (listlinie frm each other, it is (vilient that if any sudden resistance should occur while the magnet was at a distance from ilily (if the armatures, the ma- chine must necessarily stop. To avoid this (lifficulty, it was proposed to employ a 7,-. 7 - iiimnmber iif ulagnets, which s Ii o u 1 d oI)erate suecess ively one after the other, and thus bring a continuous power to bear upon the wheel.

There is an application of clectro-mnagnetism which, aithoughi it does not come directly under the head of magmietic motors, yet is a case of motion pm-educed by electro-mnagnetism. In many machines, timere are parts remote from time point at whuich tbe power is applied, whiicll require eccentric motions, and these motions must be giveii through tue agency of an endless sue- cessiomi of screws, canis, rackwork and other contri- vances, the constructiomi of wlmicim often displays much imigeimumity. but, at time samue time, such contrivances in- volve a great expenditure iii their construction, amid mmmdi power is comisumed by the frictiomm whicim they occasiomi.

Wheim a rotary motion is desired, an ar- rmimigemmment sinuilar to) L small magnetic engimme may be mnaole use of. TIme frequency of such motions can be easihy conti-elled by means of the contact breaker. rlmere are often situations where a motion either re- ciprocatimig or rotary is requmired, amid wlmere, at the sammie tinme, it is difficult to give such motions by me- chmmmmmical means-sometimes on account of the mac- cessibihity of time part to be umoved, amid in some cases becamise of the gm-eat friction or liabihity to corrosion or breakmmge of the part by whicim such niotions are trans- mmmitted.

NEWTONS IMPROVEMENT IN PRESSURE GAGES From limo Lomodoa Engimmeer.] This is an invention that relates to certaimi iniprove- ments in the construction of the Bourdon pressure gage, the object being to rcmcdy certain defects which have detracted froni its merit under certain circum- stances. Thus, for example, water accumulated in the tube has, on exposure to a low temperature, frozen and burst the gage; again, when applied to hocomotive engines, they receive a tremulous motion, and give uncertain indications through the tremulous movement of the index hand. In Fig. 2 of the accompanying engravings is repre- sented a gage of this description of the usual construc- tion, the bent tube, A, being attached at one extrem- ity to the pipe, B, through which the pressure within the boiler is transmitted to the interior of the tube. When thus constructed, if the bent tube exceeds a semicircle in length, a portion of the tube (L5 from e tof, Fig. 2,) hangs down below the point, e, so as to form a receptacle in which water soon accumulates from the condensation of vapor within it. The water thus collected is liable to freeze in winter, by which the indicating tube is often burst or strained. To remedy this difficulty it is necessary so to combine the bent tube with the pipe tbat any water that may con- dense witbin the tube shall drain back into the pipe; but it is manifest tlmat a tube attached to its pipe, as mepresented in Fig. 2, will not thus drain itself in ammy position in which it can be placed. To accomplish this end is thine object of time first part of this inven- tion, mvhich consists in so combining the indicating tube with the pipe through which the pressure within thue boiler is transmitted to the gage, that the length of tube in any direction from its junction with the pipe shall not exceed a senmicircie, and in placing the tube in such a position that it shall descend at every point towards its junction with and drain back into time pipe. When used upon locomotives, tbe gage represented in Fig. 2 is liable to another serious objec- tion, am-ising froni the violent shocks and jarring to whiclm the engine is subjected as it passes over tIme road. Ihese shiocks are of a tuvo-fold character, first, those which arc occasioned by obstacles encountered by the tread of the wheels (mi5 tIme joints of rails, & c.), and which occur in directions nearly vertical ; second, those which are occasioned by the swaying of the en- gine from side to side, and by the striking of the flanges or fillets of the wheels against the sides of the rails, and which occur in horizontal directions. The first class of these disturbances communicate to the bent tube, when arranged as in Fig. 2, a tremulous motion in a vertical direction, while the horizontal shocks to which the engine is exposed cause the tube to vibrate in directions nearly horizontal. These vi- brations of the indicating tube imnpart a frivolous vibratory motion to the index hand through a consid- erable arc, which renders it difficult, if not impossible, accurately to judge of the pressure within the boiler; they also speedily wear away the teeth of the rack and pinion by friction,the one upon the other. This vi- bration of the index hand is considerably augmented by the water of condensation which is allowed to col icet niol reulain witliiii the tliI)e, and which materially increases its weight niol momentum. To (liluinisli as fin as possible the vertical vibrations of the tube, as well as to do away with their influence upon the iii(lex hand, is tbe object of the second part of this invention, which consists in joining the plpe through which the pressure within the boiler is trans mitte(l to the gage with the indicating tube at a point l)etween the two ends of the tube, and bending the latter upon Ol)l)Osite sides of a vertical line passing through its junction with lie pipe, whereby the tube is iennere(l less sensitive to the clh~cts of the vertical shocks to which the locomotive is sul)jected. The length of tube which the inventor has found to be least aliheted l)y these shocks is iiearhy a complete circle, to which, at a l)oint midway between its ends the pipe from the h)oiler is joined, the two ends of the tlil)e approaclung each other at the toli, where they are connected with the lever which transmits their motion to the index han(i. F . In 1 is represented the improved gage, the (hal plate being removed. The ~)i~)e through which the picssure is hrought from the boiler is attached to the iLi(hicating tube at the bottom. For the purpose of carrying out the first part of this invention, the two branches, 1 and 2, of the indicating tube are made of a length iiot exceediw a seuiicircle, while they are i)oth so l)liced as to descend at every point towards their junction with the steam l)il)e, flint the water which may eoimdense within the tube may drain hack to the pipe. To diminish, as far as l)ossihle, the vertical vibra- tioiis of the indicating tube, and to lessen their influ ence 111)015 the index hand, the steam pipe is joined with time tube at a l)oint between its two extreiiiities aiid the twin) h)ranchies, 1 and 2, are bent ripen o~)posite sides of a vertical line passin6 throrigh the lower part of the tube, the extremities of the tube being nearly over the points where the tuhe is rigidly supported. The tube is formed of two branches, 1 and 2, which are bent symmetrically ripen opposite sides of the ver- tical line, that their motions in a horizontal direction may coincide as nearly a~ pOssible with each other. [lie lever, i, through which the coistracting amid cx pamidimig mIm(mtion of tIme tithe is tramismuitted to the index hand is pivoted to omme of tIme branches (1) of the tube at its cud, thic extremity of this lever being pivoted at r to a cormecting ansi, g, the other end of which is pivoted at c to the branch (2) of tIme tube the lower end of the lever, i, is pivoted at r to the rack, as, which engages with a pinion, mm, upon the arbor of the index hand, P. When thus constructed and connected, it will be observed that ripen the occurrence of a shock in a horizontal dimeethoim both branches move equally, or very nearly so, in the same (hirection, carrying with them the rmpper end of time lever, i, whichi not being imivoted to tIme case or other rigid part of the gage, simply trmrns rolmn(l tIme l)ivot at its lower end, with- ormt influmenciug time rack, am, or time index hand. This loose joint betwecim thie lever, i, amid tIme rack, iii, is also important for time purpose of preventing the me- tion of time joust at tIme cud of branch, 1, from causing the maeh to hjimid upon time l)iiiiemm, sin, or to (liseilgage itself therefrom.

JOHNSONS PUMPS FOR COMPRESSING ELASTIC FLUIDS. iiomu She Loinindon EinegineemI This imevention, communicated to Mr. Johmnsomi, by Mn. Somnicihler, of Turin, relates to a peculiar construc- tion and arrangement of apparatus for compressing air, gases audi other elastic fluids, and consists in tIme employment of a horizontal cylimider, opening at both ends into two vertical cylinders respectively. A piston is caused to work to mind fro by any prime mover along tIme hienizoiitmd cylimler. This last nientioned cylinder is filled with water, which also partially fills the vertical cylinders the pistomi is thus entirely closed by water en both sides. The two vertical cylinders are each providcdl ivithi a pair of valves kept hermetically sun-tight by hydraulic joints, thee valves and valve seats iccimig constantly covered evith water. One of each main of valves serves as thee inlet for the air or gas to be compressed, and the ether allows the compressed air or gas to escape into a pipe leading to the com pressed air or gas reservoir. The to-and-fro motion of time piston in the horizontal cylinder causes a simul- taneous elevation of the water level in the one vertical cylinder, and a corresponding depression of the water level in the other cylinder. As the water level de- scends, the extenimal air (if it is sought sinmphy to com- press atniosphenic air) enters the cylinder by the inlet valve, at time sanie time a small quantity of the water which sumnroumids that valve escapes into time cyhiiider with the air, and at the miext stroke of the piston the raising of the ivater level compresses time air above the water in the cylinder, amid forces it through the outlet valve into the pipe leadina to the reservoir or air ves- sel; a small escape of water again tahUng place with time air out of thee cylinder, it is thins obvious, that during the ivoiking of the apparatus, theme is an inter- nmittent entramece of )vater into the cylinders, and a cornespondimug escape of water therefrom. This supply mummy be maimetained by any meatural and constant source, suche as a niountain stream, ameul thee water which escapes flows into a reservoir fitted with a float and val~ e, so that wheemi a certain quametity of water has ruiim into the water reservoir, the float will rise opeme an escape valve, and allow the water to run off until the descent of the float again closes the valve. A is the horizontal cylinder, within which works to audI fro the piston, P, actuated by any convenient prince immover. This cylinder opens at both ends into tIme comimpressing cylinders, B and C, respectively ; M is a hionizontal cylimedrical reservoir, in which is placed mu cylindrical float, C, a free space, a, being left be- tween the exterior of the float and the interior of the reservoir, as shown in thee dlrawimig ; Pu is a water reservoir em tmuumk, )Vhiieim is kept comestantly Suliphied fiem muucy niatumrmil on other convenient source, and is providled with two cocks, r ~ which direct the water lute time two vessels F F, respectiveh~ S and S are twin inlet valves fos time enmt.uance duf thu mini mini us to line linullmh)lessdini umito tim dinilimpiessing in yh I iminhin us () (7) are two ethics valvu ii lihehi admmiit of the d eat of thie ceminipressed minim or gas f noun tue cemuipressing, respect- ively ; mind z is minumotim in milve fitteul iseto time bottoni of the neseuvoms M, mmml coimnected with the float C for the purpose of effeetheg the peniediceul emptying of the reservoim,mis hereinafter described; T T are two lion- AN Amenicauc, who calls hcimsmsclf Dr S.

Thee piston evorks to amid fro in the water, which always ucahetaimis an air tight joint, and the tightness of the valves, S S and 0 0, is also maintained perfect by keeping thens constantly imumersed in water by the aid of the respect- ive vessels, X X and Y Y, which are always maui- tamed full of water at a constant and invariable level, which water effectually prevents the return of time aim or gas, whether at the inlet or exit valves. rice coins- pressed air or gas in the cylinder or coinnpressing chiamubers, B amid C, passes out by tIme valves, 0 amid 0, simnultammeorisly with a smicahl dpsantity of water, which is carried along with it smiechanically, audI expemmeinis hi the space, X, wleesice it passes by the tube, T, imute thee receiver or magazine. The small qumantity of water which is carried over by tIme air into the space, X, serves to keep the vessels, Y IT, constantly supphiedi, thee surplus water flowing off into the reservoim, M. When this waste evater has attained a certain level iii the reservoir, M, it elevates thee float, C, evhiichm draws with it and opens time eumptyimeg vmmlve, X, tlemdurmghm which the evater escapes by the aid of time tube, 1, amid under time pressure of the air or gas in thee space, X, above. Time escape of time water causes the float, C, to descemid again and so close thee vmmlve, z, until thee further supply of water again elevates the float and valve. Thus the water supplied by the cocks, r in, him two continuous jets, after having fulfilled its purpose of packing or keeping air tight the imehet vmulves, is expelled intermittently and automatically from thme apparatus at the same tince withe the watem canmieuh alomeg by the compressedl air. Altlmormgh thee cemistamet adneissiome of fresh cohul water into the apparatus might be dubjected to ems teme(l- ing to a certaimi extemit to diminish its useful effect, yet this entrance of cold water acts beneficially iii otimer respects by keeping down the temperature of the muppa- ratus, as it will absorb the heat generated by time coni- pressiome of thee air or gas. Supposing the apparatus to be started, time piston, P, evill travel from a to 6, and the outlet valve, 0, of the chancher, B, close. Thmis cylinder, B, is completely filled with water, whilst ism the cylinder, C, the water reaches osily to time level, a mm; the resimaimmimig part of theis sceouid cyhimidler is filled evith muir or gas, as time case immay be. Now, hrmninmg time course thee linistoim travels, fromem a to 6, the leech, mm a, will rise and comumpress time air mubove it umetil it fences open the outlet valve, 0, amid eseempes in the spmmce, X, and thence by the tube, T, to the receiver. On tIme arrival of the piston at b, or the end of its stroke, time valve, 0, closes again, and is kept tight by thee presence of the water evhich covems it in the vessel, IT. Should this valve be imperfectly mmmdc, a leakage or black floev evill take place thiroughi it, dusimeg the retrinum strohie of thee piston, from 6 to a, butt this leakage will only be a small quantity of evater, and inset of the coin- pressed fluid inclosed in thee space, X. Whilst the piston has been travelling from a to Is, the inlet valve, 5, of the cyhimeder or chamber, C, has, of course, re- ucained closed, and beemi kept air tight by thee evater ime the vessel, Xlii wheich this calve is immemersed. In the same manner described, with reference to the valve, 0, amid leakage through this valve will memely result in the escape of a small quantity of water, evhilst the compressed fluid itself is retained in the cylinder. The operation of the cylinder, B, during the retuirn stroke of the piston from 6 to a is precisely simecihar to that already desemibed in reference to the cylinder, C, hint it has in the meantimuee beemi filleini with air or gas throughe the inlet valee, 5, amed its evater level imas descended to time line, minin in, so that evhen the piston beams to move frone 6 to a time air or gas above mini mum evill be comuspressed and forced omit evemitually through the outlet, 0, into the space, X, and receiver.

There is prol)ahly no other piece of mechanism o~ equal simplicity which has been the subject of so much study as the power loom. There being thousands Of these machines in constant operation, under the super- vision of skillful and intelligent mechanics, every part and motion has, undcr tlic impulse of the patent laws, been the theme of a great (leal of thought and con- trivance. As the cloth is woven, it is necessary that the sides should be stretched apart to prevent the web from becoming narrow and uneven, and the mechan- ism by which this office is performed is called a temple. The fact that there are several classes of these little implements, illustrates, in a forcible manner, the truth of our assertion in regard to the invention which has been bestowed upon the power loom. The improve- ment which we here illustrate is in that class of temn- l)les known as the spur plate temple. The inventor says that, though it seems to be the plan which a l)clson would naturally adopt at first for making a teml)le, its pmohmetien has cost him five years ot reflec- tion an(l exl)eriilient; an additional proof to the thousand others of the general tendency towards sim- plicity in mechanism. Fig. 1 of the annexed cut is a perspective view of the ~vhole implement, and Fig. 2 is a sectional view, show- ing the imuiner in which it grasps the cloth. The in- vention consists hi inserting the teeth of the temple Puto a l)ieee of woo(l, which is fitted to the plate of the temple in such a manner as to be removable fos the purpose of renewing the teeth when worn out or in- ured. WI Fig. 2 rhe piece of wood, (, is made of both tapering and dovetailed shape, to fit into the space of corresponding form between the two projections, b b, which rise above the surface of the plate, A. Passing through the wood from the lower side, are the pointed steel teeth, c c. These teeth have both a forward inclination towards the breast beam, and an outward inclination toward the side of the loom, which position prevents the cloth from slipping back, nail also prevents it from slipping off the teeth in a lateral (hirection, as it is stretched by the action of f lie reed when the latter beats up the filling. The l)ieee of wood, C, being easily removable, it can be renewed with a set of teeth when these are worn out, or any broken or injured tooth can be re- placed without taking the temple from the loom. The cap, D, which is ma(le in one piece of metal with the arni, E, confines the cloth to the teeth, c C; it has a depression over the teeth so as not to come in con- tact with the latter, and it is held either open or closed by the spring, g, which presses against its short arm beyond the fulcrum pin, d. A short stud, f, fits into a hole in the arm, E, to hold the cap securely in place when the temple is closed. rrhe temple is attached to the breast beam of the loom by the stout spring, U. To persons wholly miacquainted with the matter, this may seem a small modification to 1)0 secured by Letters Patent, hut those who understand the value of improvements in even the (letails of mechanism which is in extensive use, will readily believe that it may be a means of independence to the ingenious inventor. The pategt for this invention was granted, through the Scientific American Patent Agency, Dec. 11, 1860, and further informatiop ip relation to it may be oh- tamed by addressing the inventor, Jeremiah C. Tilton, at Sanbornton Bridge, N. H. WORTENDYKES IMPROVED WICKS FOR CANDLES. The object of the invention here illustrated is the production of a wick which will burn in tallow candles, as well as in those of less fusible material, without snuffing. This wick also requires less weight of ma- terial than those in common use. For accomplishing these objects, the simple plan re- sorte(l to is to make the wick of several strands, b b b b (see cut), each of which is formed of two or more yarns, e n e a; the strands being twisted in the same (liieetion as the yarn, and the wick being twisted in tIme opposite direction to the strands. When we consider the immense number of candles which are consumed in this broad country, we shall realize that a decided improvement in wicks is an in- vention of very, great value. The patent for this invention was granted, through the Scientific American Patent Agency, on Jan. 1, 1861 and further information in relation to it may he obtained by addressing the inventor, C. A. Worten- dyke, at Godwinville, N. J. Death of Professor Hackley. We regret to announce the decease, on the 10th inst., of Professor Charles W. Hackley, of Columbia College, this city. At a comparatively early age, he was cut off in the full vigor of his intellect, and called away from scenes of great usefulness at 52 years of age. He was educated at the military academy of West Point, and was teacher of mathematics there for several years. From 1833 to 1839 he filled the chair of nmathe- matics in the University of New York; then he became president of Jefferson College, Mississippi, from which place lie came to Cohmmmbia College in 1843, and at his death was professor of astronomy. He was the author of several elementary works on science, and took an interest in all that related to astronomy and mathe- matics. He exerted himself in directing the attention of the public to the importance of erecting an astro- nomical observatory in this city. Applying the prin- ciples of acoustics to rooms designed for public speak- ing, he projected the method which has lately been introduced into several churches of the city, consisting of a sounding board which throws forward the voice of the speaker among the audience. His death was occasioned by a nervous fever. He leaves a large circle of friends, whom he had won by his kindness of heart, his gentleness of manners, and his useful life. FnATEnNAr.The (ouoliq (leo/lramon, published at Albany, N. Y., by the veteran Luther Tucker and his son, in alluding to the prosperity of its agricultural cotemporaries, the Maine Fume,. Moores Rural NimL, Yorlrer, the American Agriculturist, and .Jliaerm Rural American, says that among our non-agricultural ex- changes, the Hone Journal and the SciENTIFIc AMERICAN are to be ranked among the most perfect specimens of the art of printing we receive in newspaper form. This is certainly a high compliment, the correctness of which, as applied to this journal, our readers can judge. From our own knowledge of the Ilaaie Journal, we are certain that the Country Gentleman is correct. Messrs. Morris & Willis, and their famous Home Journal, are known everywhere. A new volume has just been commenced. Human Power over Brute Force---Rareys Method of Taming Horses. The mode by which J. S. Unrey, the world-renowned subduer of wild and vicious horses, accomplishes his marvelous feats has been very widely discussed, and it is now being practically exhibited by him at Niblos Garden, in this city, by the taming of the very worst horses that can be found. Ills treatment con- sists in two thingsfirst, in showing the horse that he is in the mans power, and second, in convincing him that the man means him no harm. In order to obtaimi absolute physical power over the horse, the simple plan is adopted of bending his fore legs and securing them by straps in this bent position. This of course throws the horse upon his knees, in which position lie remains but a short time before he becomes so much fatigued that he rolls over upon his side. The tamer now handles himn gently, patting and stroking himim, fondhimig his head, putting it under his arm, turning him about on his side, & c., until the horse is thor- oughly satisfied that the man is kindly disposed towards him, and has no design of doing him any injury. When these two ideas are fully implanted iii the liorsas mind, that the man can do what he will with him, and that he will not use this irresistible power to the horses hurt, the work is donethe homse is subdued. To overwhelming power, combined with perfect kindness, he yields prompt and absolute sub- mmssmon. At Mr. Rareys first exhibition in this city, a muzzled horse was lead in by two grooms, which was such a vicious aninmal that he had not been used in four years. He had both the wicked habits of kickimig and biting. In just thirteen mainutes froni the entramice of the horse upon the stage, Mr. ikarcy laid his head betweemi the horses heels and placed his armn in the horses mouth! Fitzgerald & Bates Method of Igniting the Charge in Ordnance, & c. This invention of Mr. Fitzgerald, of Cambridge- street, and Mr. George Bate, of, Great George-street, conists in firing the charge in cannons, muskets, and other firearms, by means of two chemical substances or compounds, by which fire is generated as soon as the substances come into contact with each other, by per- cussion or otherwise. By way of exemplification, we will describe one arrangement of gun and omie set of chemical substances, which the inventors find to answer well in carrying this invention into effect. In an angular direction through the breech is formed a tuhular aperture, and to the front of the hamnier of time lock is hinged a pin or bolt, which fits accurately in this aperture. Over and opening into this aper- ture, at a point in front of the inner end of time bolt, when the hammer is drawmm back or at full cock, is placed a reservoir or hopper, and in this hopper globules formed of a mixture of chlorate of potash and suiphuret of antimony, in or about the pro- h)ortion of two parts (by weight) of the former- to omie of the latter, with a sufficient quantity of gum, gela- tin, or other like suitable agent, as a vehicle for form- ing the composition. The opening from the hopper is so calculate(l as to allow passage to one globule only at a time into the tubular aperture, and then only whemi the hammer is at full cock. The back emiul, or the paper imitended for applicatiomi to the back end of the cartridge, is prepared by apply- ing a coating of a composition formed of about one part of phosphorus (by preference amorphous phos- phmorus), one part of suiphuret of antimony and two parts of emery powder, with liquid glue, gelatin, gum, or other like agent. These muaterials are compoumided nuder a degree of heat suflicient to melt the phosphorus. In some cases they apply the paper to a wad at time back end of thu cartridge. In the accompanying en- graving, A is the plunger in coummection with the trig- ger of the gun, B is the reservoir for the globules, and C is the cartridge. In tile case of ordnance, tile pat- entees prefer to ignite tile cilarge by inserting in the vent hole a tube partially lined with the prepared paper described, which is brought into frictional contact with a portion of the compoumud used for mnaking globules. 56 (U .m47.7 ij ,-- - - MUNN & COMPANY, Editors and Proprietors.

The sllbjeCt of firearms has engaged muCh publiC dis- (ussiOn during the past few years, ~tnd it is now tttttcting mOrC attCntion tisan ever. Nearly all EuropC appears to be an armed Camp. England has two hundred thousand volunteer riflemen in Constant drill; and at home, the notes of warlike preparations rCsound throughout the land. For two Centuries, the freC yeomen of America and tile sttlr(ly Switzers of the Alps were alone distinguished for skill with the deadly rifle but it has now become the weapon of all armies and there is ito nation which can claim pr& eminence in the skillful 115C of it. The first correct writer on the rifle was Robbins, an English soldier, who wrote upon the subject about a hundred years ago. He explained the defects of the smooth bored musket, described the principles of the rifle, pointed out its superiority, and (leclared that, by whatsoever army it was adopted, wonClerful effects would follow. The theory of the rifle is now generally known, and the advantages of this weapon are duly appreciated. But there are great ttltd essential varieties of rifles, and, of course, all cannot be equally good. There are breech-loading and utuzzle-loading rifles; there is the light English rifle, with its sutooth tapering barrel: the heavy Swiss rifle, with its thick breech ttud muzzle; linCI the long heavy American rifle, witit its octagon barrel. There are also very great differences in the pitch of rifle grooves, and other teatures which ttre far from being unimportant. On these points iisuch has been written that is more (Iiscllrsive than instritetive. .1. Chapman, author of American Rifle, and Colonel Jacob, of the East Iht(lia itrlisy, are perhaps among the best writers on this snbJ(ct. A series of articles on small ttrius isas also lteeit ltlt(ly pcildishctl in the London illeclooiica JJege zinc, by ~V. Britlges Adctms, it prttctical engineer tcnd writer on mechanical 5111)jCCfS. Some of his views are full (if gt)otl sense, while others exhibit a want of thorough laractical acquaintance with rifles. Europeatt writers on firearms seem to be unacqitainted with witat htts been done in Amcrictt by our guasnuths. 1he conical or elongated Minid projectile, whicit has htecoute the favorite in Europe, is tice 01(1 picket bullet ilsid by Atnerican riflernets, witit the addition of a Chittlulter tusd plug itt it~i sterns. Adams says: All lc)rCih)ie expansion of leaden bullets within the barrel by the explosive actiolt of the gas is a mistakeit wastes l)owdcr and alters the form of the shot into irregularities, tending to irregular flight. He thus (leclares tinat the expanding bullet is not reliable for accurate sisooting. We have seen several experiments utade witln the expanding ttnd the old solid picket bullet loaded at the muzzle, in which the latter always proved the most reliable. It must be acknowledged, how- ever, that the expamnding ball has its advantages in warfare. Witlt it, a soldier can 1011(1 his rifle inS easily and 115 fast as a utusket ; ttnd if it is not quite so rehitcble, it is better for rapid firitig titan the solid ball. But it has itt) otiter ntdvantage flush) this ; nus(l ntbove all things, certttiitty of striking sisould be t lie first object ut firectrins; quick shoot iiiN if we can, but accuracy by all means. Americait first class rifles are the best in the world. The foreign Enfields, Wliitworths and Lancasters are far inferior to them. ~lhse reason of this is obvious. Rifle shnootirag Itas been a fttvtrite American timusement fora hundred years, and it has been a matter of national pride, as well as of security, to excel as marks- men. TIte greatest care and the highest mechanical skill have been called into requisition on the part of our gunsmiths to make perfect rifles, and they have been successful beyond all that Europe can boast. A Wesson a James or a Fish rifle is always a dead shot in the hands of American marksmen: the instrument, when in proper order, never fails. At present, we believe that the muzzle-loading rifle, with the tight fitting conical bullet, is the most reliable, and the principles involved in its construction are few and simple. Tite barrel should be of the best close- grained cast steel, and its weight sufficient to give it stability. It also appears to be advantageous to have tite barrel of an octagon form, and of thte same diam- eter from end to end. When the charge expands in the barrel of a rifle, a series of undulations are pro- duced, whtick operate to give irregularity to the flight of the projectile. The angles of the octagon rifle bar- rel tends to arrest these undulations. This was dis- covered long ago by our backwoods marksmen; but this principle does not seem to be appreciated by most army officers, who have provided round barrels for tlteir rifles. The size of the bore in rifles is a matter of convenience and choice. The larger the bore the greater proportionately should be the weight of the barrel, to give it stability. The interior of the rifle shtould be as smooths and polished as the inside of a steam cylinder, to avoid friction in the passage of the bullet. There is quite a difference of opinion as to the best length for rifle barrels. This is an important feature, because the pitch of tine rifling is always in accordance with the length of barrel. The heavy, long western rifle, with its moderate spiral, is considered by many persons to be the most reliable; while others assert that a short barrel, with a slow starting spiral and an increasing twist touards the muzzle, is as reli- al)le, and is preferable to the long barrel. The number of grooves in a rifle is not of tnuch importancetltree are better than a (lozenprovided the bullet be made to spin properly; they should be as shallow as possible, however, to prevent windage. The German rifles have short barrels and a rapid twist. Colonel Jacob states that he found, by maffy experimnents, that a barrel two feet long, witit the grooves full and of a breadth equal to the leads, and giving a revolution once in three feet, was C(lual to barrels two and a htdf and three feet louw a Tine muzzle of a rifle should be perfectly true ; for if there is the least defect at the issue where the bullet leaves the barrel, shooting becomes mere chance work. Clarks patent loading muzzlean American inven- tionhas conferred a superiority for accuracy on all rifles furnished with it. It is admitted flint rapid loading is desirable, and that this is obtained with expanding bullets; but these are not rehitsbhe. But, then, are not accuracy and rapidity of firing combined in breech-loading rifles? The late Secretary of War, in his report, said: I thimnk it may be fairly asserted now thnst the highest efficiency of a body of men with firearms can only be secured by putting into their hands the best breech- loading firearms. This conclusion, it seems, was arrivefi at after a great number of experiments by army officers. There ctstn be no question as to the ease and rapi(lity of loading breech-loading rifles, but they are not comisidered Sc) aecctrate in finitig as a good utuzzle- loader. We have seen several trials of skill witlt the two kinds, in which the breech-loader usually failed; and yet we do not see why this should be considered a settled question. There is nothing in theory, and there should be no positive difliculty in practice, to prevent a bteech-loading rifle from being made to carry as accurately as any other. We shall recur to this subject its a future article. THE NEW COMMISSIONER OF PATENTS. The inquimy is frequently made of us, who is likely to be appointed Commissioner of Patents under the incoming administration? Our readers are deeply in- terested in this matter, and hi view of the vast and increasing importamtce of the interests over which the Commissiotter of Patents is called to preside, the inquiry is a pertinent one. We are not in the counsels of the acting President or President elect, and have therefore no authority to speak for them. This much, however, we will say, that the appointment of a Commissioner of Patents is an important matter, and it ought not to be conferred mhteiely to provide a place for some windy 57 political demagogue, as a reward for stump services. Neither should the selection be made of one who has searched into the profound mysteries of some science and knows but little else. The duties devolving upon the head of the Patent Office are somewhat peculiar, and require ~ the right man for the right place. He must have considerable patience, a willing ear, ahid a firmness of purpose not to be whicedled out of tine path of progress into old fogy notions. He must have not only a knowledge of law, but he ought also to be able readily to distinguish the difference between a cheese press and a hydraulic rain, and even, to go further, when necessary, to protect the rights of an inventor by overruling wrong decisions. His habits, conduct and language ought to be high-toned atnd above suspicion. In short, he ought to be a gentle- man, possessed of good common sense, having a gener- ous appreciation of the interests of inventors, so as to welcome them to the Patent Office in free and frank intercourse ; and if an inventor should happen to suggest that his rights had not been fully respected, not to swear behind his back, nor consider it am attempt to cast odium upon a high public functionary. There are plenty of solid men in this stirring coihtstry, possessed of all the desirable qualities herein mema- tioned, and who would, doubtless, cheerfully accept the appointment if tendered theiis. The only name we Inave heard suggested for this office is the Hon. Butler G. Noble, of Wisconsin. From what we know of this gentleman, we should think he has all the elements necessary to make an admirable Commissioner. He is a lawyer by professions, and has a knowledge of the arts and sciences surpassed by few men in the country, to say nothing of his capa- city for work and his readilness to do his whole duty. Mr. Thomas, who retired from thte Patent Office to assume the duties of Secretary of the Treasury, has re- signed his new office, and it is stated in the Daily Toetes that he would probably again resume the duties of Commissioner of Patents. This we consider wholly improbable under the circumstances. The duties of the Patent Office are now acceptably performed by Mr. Shugert, amid we hope no one will be placed over him. We should be most happy to announce the determination of Mr. Shugert to abolish that useless appendage, the revisionary board, and inaugurate some other changes in the Office such as would relieve it from suspicion of imbecility at least. THE FERTILITY OF INVENTORS. We published last week an illustration of the niode of spiking cannon, and it would surprise any one who has not come in actual contact with the inventive genius of the country, to learn the number of sugges- tions which have been made to us of improvements itt this simple operation, both for spiking cannon and for restoring them again to usefulness. If the atteIs- tion of our inventors is called to the need of any im- provement, however difficult of accomplishment it may appear, it is surprising how promptly some means of effecting it will be devised. A few years since, an extensive worker of marble, in New Hamp- shire, offered, under special conditions, a reward of $10,000 for a machine for sawing marble in a particu- lar manner which it had been deemed impossible to effect by machilnery, and the plans poured in upoms him ins such abundamice, tinat he was not only embar- rassed with scores of personal applicatiom~, but had so many letters upon the subject, that he w?ns led to ex- claim, Hold, enough! Very many of the operations which are now regu- larly performed by machinery, would have been re- garded, a few years ago, as absolutely beyond the power of mechanism. Who would have thought, for instance, that a peck of pins could be poured into a hopper, and that a machine would take them all by the heads and insert them in straighat rows into papers, with a rapidity and regularity unapproachable by. hand work? Here is a loom, driven by a powerful water wheel or steam engine, and running with great force, weaving with rapidity a very slender cotton thread into a web, and if the tender thread breaks, the loom instantly stops. A piston is moving back and forth in a steam-tight cast iron cylinder, and the vary- ing pressure of the steam, throughout every portion of the stroke, upon each square inch of the inside of the cylinder, is accurately recorded by the engine itself upon a sheet of paper with a lead pencil. What man can pronounce any mechanical or scientific aebievement 58 mpossible who reads every flay, iii his morning paper, he news sent from all parts of the country by that lerpetual won(Ier an(l miracle, the electric telegraph if any person perceives an opportunity in any art for an ilnl)rovement which would be of unquestionable money value, or any operation which it would be l)rolital)le t have performed by mechanism, however impossible it may seem to eftbet it, let hhn write a short note to the SetENTirie AME1UeAN, calling the attentiomi of our readers to the matter, and we can almost insure himii a speedy solution of the problem. Difficulties only stimulate the resolution and inge- nuity of inventors. The niore formidable thc problem tIme greater the satisfaction hi encountering and over- coming it. impossible ? said Napoleon, never repeat to me that blockhead of a wor(l. THE WAY WEALTH IS DISTRIBUTED. We have seen that wealth ~s l)mo(llmee(l by the joimit actiomi of labor and eapital or, rather, by labor using capital as tools to work with. A man might raise a certain amount of corn with his naked hands, tearing up the earth with his fingers, and keeping it clear of weeds with time same means. lint how much more lie could raise by the aid of a simple hoe lie could pm- duce more still by the use of a horse and plow, and still more with carts amid all the modern implements of Inisbandry. All capital, from a hoe or ax up to the most elaborate manufactory, may be ~roperly re- garded as tools in the hands of industry, increasing its product of wealth. Now, when the cal)ital belongs to the laborer, as is the ease u ith many of our small farmers, there is no division to be made of the product.

The india-rubber tree from which the gum is obtain- ed is a native of India and the Brazils the product of ]ara in time latter conntry being very far superior to any other. L:srge quantities, however, are imported trom Java, Penang, Singapore, and Assans, and these, though inferior in qiemhity, enter largely into india rubber ~nanut~sctures. The Para gum is obtained chiefly from the Sipho- nia elastics, a species of seringaby which name in- deed It is commonly known by the nativeswhich grows in great luxuriance through all the forests in the Brazils.

India-rubber was first brougist to Europe, it is sup- posed, by some French travelers, on tiseir return from South America, in the year 1730, and in tlse year 1736 M. de in Condamine read a paper before the French Academy, on its wonderful properties, describing the tree from which it was obtained, and the rsmode of pre- pafation. More recently we find it mentioned in our own country by Dr. Priestley in his introduction to The Tiseory of Perspective x. D. 1770; wherein he speaks of it sins newly introduced, and praises its quail- ties for removimsg pencil marks from paper, adding that the vendor of it is Mr. Nairre, instrument mssaker, opposite the Royal Exchange, where it can be bought in cubical pieces of half an inch for three shil- hugs sterling How little was then foreseen of its valuable proper- ties; and, indeed, how ninny of the present generation renmeirsher it sins only used irs their school-days for s-nb- bug cost eoistoo/ccs, or for tire clandestine nmrrsuscnsent of ehsewimmg time latter foreshadowing the present plains of mastication~ which it undergoes in the pro- cess of manufacture. From 1770 to 1791 rsothing seems to have been done with time new material, though attention had been drawn to its womsderful power of elasticity arid its resistance to wet. Time grand difficulty, however, was to fimid a solvemst for it of such a nature that it irsigist be easily snarsipulnuted. Irs 1791 the first patent for effec.ting this was tsmkems oust by Sausnel Peal, who clainsed mrs improved rssetisod of making waterproof all kirmds of leather, cloth, & c. ; wimick he accorss- plishmed by o dissolvimsg by (histillatiosm or infusions over a h)risk fire imsdia-rubber in spirits of turpentine, and timems spreading it oms his cloths or other material by the aid of a bros-lu, & c. Here is the gerrrs of our pre- semst waterproof coat for which Sansuel Peal deserves mu miations s tisankspeace to his manes. During the next thirty years, though little was done ims tlse way of mmdvancement, the wonsolerful properties of the nsaterial had attracted tise attention of several huge nious mad inventive usinids, who gave their whole tinire to its stumdy. Cisief arminong tisese stamid oust the moamuses of Thormmas Hancock in Emsglansd, uinmsd Charles Goodyear, in Annierica, who were veritably, by their indomitable perseverance, the originators and perfec- tors of the present india-rubber trade. In 1820 a patent was taken out by Mr. Hancock for the applica- tion of gum elastic to springs for trowsers, gloves, shoes, & c., wimich to the present day, tisough in a usuchs inmprov(-d foriss, are msnsonsgst its most valuable rises. 1mm 1823 another step was takers by the patenstirsg, by Charles Macintosh, of the svell-known waterproof gar- ments which bear his name. These were advances in timom right derection, valuable in their way but yet far sisort of perfection. Onse of the largest articles of ecasursiption in the early days of india-rnrbber was tise overshoe or galoshe msot the ehegamit ripper which we now have, but a clunmmsy piece of native marsufacture.

This reached its height in the year 183435, when, to the dismay of all inter- ested, it was found that the gum, after passing through the process of manufacture, would not withstand the field for genius, and the man to seize the opportunity was Charles Goodyear, wiso, by imidossnitabie coumrmmge, umuwearying sturdy, amind the enidusrausce of priv atiomns sunch as fall to the lot of few sliers, at hnsst discovered a nseans to overconse this decouspositioms, maid make india-rubber whsat it now is. ~Tc be ccsnnismosed!.

He intro- duces a permanent maguet in such a way as to induce mtignctism in the soft iron core of an clectro-magnet, so that in passing in oue direction it adds its power to, 411(1 in passing in the other direction it subtracts its power from, the magnetism induced by the battery. 1-Ic is titus enabled, by one movement of the key, to coutbine the two powers, and consequently to produce a signal witlt a current so weak that ~x ith the ordinary electro-magnet it would be impossible to preduce any signal whatever. Whert the spring is once adjusted, there is no difference between a strong and a weak cur- rent, so that it requires DO further adjustment. The iIlol)rovements embrace this use of a permanent mag- itet, an improvcd spring for adjustment, and an im- l)rt)Vcd method of preducing signals by sound. Mr. DinalIx inquired if there were two motions of the linger in producing tite signal. Mr. HoLcoMaIt is by 1)reaking and connecting; it is one motion of the finger. Mr. STETSONCan ~t)li telegraph tarther and faster witit this? Mr. HoacoMaThat should he the result ; both farther anti faster. I have a patent, not for the con- tinuation of a permanent magnet, but for securing the current in producing a single signal. Mr. IDIanENUsiag two signals to make one? Mr. lloacoIumYes, sir; theoretically there are two motions, practically, one. Mr. SEELvIhere is certttinly novelty here, and if the gentlematmas position is correct, lie has made a very valuable discovery. Witlt the means we have heretofore used, we get twice as much available power as heretofore. With the battery, we get a certain poner, and with the common magnet a certain power; and these may botlt be weighed. By the combination you increase the effectiveness without increasing the cost. I have seemo the experiments by which Mr. Hol- comb, in part, thinks he demonstrates it. The experi- meitts lean to~varrls that conclusion ; but they are not without ohqcction. Mr. Holcomb feels quite sure that his discovery is genuine, and I understand him to come here to invite experts in magnetism and elec- tricity to examine Itis evidences and refute him if he is wrong. The manipulation of the key is precisely the same as of the ordinary key; but at each move- miieiot of the key you break the current, reverse it, and restore it. 1ressing the key the current is broken pressing it further it is reversed, and relertsing it the citrient is restore(l. BiJTTON-ILOLE SEwiNG MAcnINE. Mr. TOwsaEr exhibited Vogels Button-Hole Sewing Machine (noticed on a former evening) and specimens of its work, aitd cxplained its operation. It makes six different stitches, and is constructed with such sim- plicity that a novice may learn in a short timue to work the machine with perfect facility. hutton-holes can be worked with perfect ease at the rate of 100 per hour. Some of the specimens make floe stitch some- what open, but the stitch may be regoilated as in other machines, so that it shall be as close as handwork. Ihie machine can he worked with two, three, four, or five separate titreticls. In working a britton-hole we may carry a cord upon the upper side, or upon the lower, and ~vork over it, and work with the same rapidity that we work without carrying the cord. He regarded the buttonhole stitch itself far simperior to that made hy hand, for the reason that it is almost as elastic as any goods it is print upon. With the identical machine exhibited, any class of goods could be sewed, from the finest tabrics to harmoess leather. rThe machine makes two different kinds of buttonholes ; one of which would he pronounced by a tailor to be a French but- par, which is an oxyd of aluminum, and probably was tonhole worked by hand.

A gentleman from Pennsylvania gave some statistics to the same effect. Dr. STEPHENS made a few remnarks upon ancient pot- tery. The ancient potteries found in thine United States were made by tribes of Indians driven out of the country before its discovery by Europeans, of whom the only reimresentatives now are the Puebla Indians of Mexico, which are white, and entirely distinct from the copper-colored Indians. They did not possess the art of glazing; but they hinad much taste, and produced ware which was highly ornamental. Mr. JOHNSON desired that Dr. Davis should have unit opportunity, at the next meeting, to read his paper upon pottery. Mr. SEELv was prepared to make some remarks upon the chemical aspects of the subject. The subject of pottery was continued for discussiomm at tIme next meeting. Mr. HEmimeu suggested that glass shmormld be consid- ered in the sanine commnection, especially in time elmemical consideration. On motion, the meetimog adjourmoed. POTTERy. It had been announced that Dr. Davis would read a paper upon this subject; but he was not present. Thle PRESIDENT made some remarks upon th~ uni- versal diffusion ot clay upon the surface of the earth, and upon its strong affinity for silica, so that a large proportion in potters ware is silica. It was note- worthy that clay, while the noost easily used in the arts, pottery being one of the earliest inventions of savage tribes, and clay burned or dried in the sun being an early building material, contains within it a metal for which the developments of the present day seem to prophecy a usefomlness in adv~ need civilization above that of most if not all other metals. Mr. JOHNSON exhibited some specimens of images fi~om Siam, and also specimens of Mintons encaustic tiles. Mr. BousE, a practical manufacturer of Jersey City, said that all the materials, except flint, can be had, as good in this country as in Europe. In crockery ware, out of 32 parts, 22 parts are the blue-ball clay, or Jer- sey clay, or coonmomi white clay. This conies, a large part of it, from Woodbridge, near Perth Amboy, N. J. Most of our table ware is imported, not more than one- thousandth part being made in this coromotry. And it has been bunt a few years since the Amuerican manufacture hias been successful. But now thoat flint and borax are admitted duty-free, we can compete successfully with Staffordshire. Thie flint is imported, ground, at less thian a cent per pound: whereas they could not grind it in this country at less than two cents. The cost of transloorttttion from Staffordshire to Liverpool, and then froni Liverpool to New York, the fornmer being gr(~tter thinami thoc latter, was sucho that we cormld miiider- sell tIme inoported ware. Every manufacturer has lois own secret in mixing thme materials, and mimome par- ticularly in thie glazing. Thiousands of dollars are sometimes lost from an imlirohier proportion. For in- stamice, if one of the materials is not groumod .so finely as another, whmemi they are passed tlmrommgh thme lawmi, or bolting cloth, an omudrine proportion of it may be ex- cluded, and thins spoil the whole batch. It camortot be detected until the work is fiminished ; when it may all fly to pieces in glazing. Dr. STEPHENS said that thie clay used in time manu- fimeture of earthen ware is amo oxyd of aluminum, and comitains a considerable portion of silex, arod often of lime amid potasho. If it contaimos too much potash, it whil run or fuse. Most of time clays found in the carboniferous regions of the United States are of that character. The clays foumid in this neighiborhood are confined to thme cretaceous or chalk formation, begin- ning at Marthas Vineyard, and extending southward to Texas, and northward to the Arctic ocean. The clays of the Pacific ocean belong to the testiary period.

Improvements in Marine Engines. The arrangcment of steam ennines in boats and slLll)s has furnished a full opportunity for the exertion of the very hi~hest engineering ability that the world has ever known, and there is still room for the expendi- ture of an indefinite amount of h~genuity in this de- partment. As Great Britain has the largest number of sea-going steamers of any nation, the largest amount of attention has been bestowe(l in that country upon all l)arts of their structure. The following description of an improvement patente(l in England by Mr. J. F. Spencer, which we find in the London Engineer, we re- gard of sufficient ilnl)ortance to justify its transference 64 line of the keel, and either horizontally or slightly in- clined, end thus insures, as in the case of the applica- tion of the surface condensers to inverted screw en~ines, ready access to the tubes of the condensers, and the fa- cility of removing them by withdrawing them from the case forming the central condenser, to which is con- nected each cylinder. It is intended, though not indis- pensable, that the condenser should form the support for the central bearing of the paddle shaft, Mr. Spencer prefers to employ the following descrip- tion of slide valve In ordinary marine engines, it is usual to relieve the main slide from the steam pressure by a faced ring at the back so fitted as to prevent the to our columns steam acting on a given surface of the back of the In (lescril)ing this invention, and the modes of carry slide but when cut-oft slides work on the hack of the ing it into effect, the patentee illustrates its applica main slide, the arrangement ordinarily employed for tion to engines intended for driving the screw propeller, relieving the pressure cannot be effectually carried out. an(l he adopts for this pnr~~ e a type of engines which, But he is enabled to use one or more cut-off valves or i/742 lie 1)elieves, particularly suited for commercial marine slides, aml at the same time to relieve the main slide purposes. from the steam l)rCsSllre on its back an(l this is effected In constructing (lireet-actiug screw engines with in- by causing the cut-off slide or slides to work in a chain- verted cylinders, he introduces under the cylinders and ber of a rectangular, or approximately rectangular, between their vertical centers a central case or hollow section formed at the l)ack of the main slide. This frame of a suitable form, and of sufficient. size to receive chamber may either be a portion of the casting the arrangement of horizontal tubes forming a surface of the main slide, or a separate casting bolted condenser. In this comlenser the tubes are placed ho- on. It is formed by surrounding the back of the main rizontally or cut slightly inclined, and are in each case slide with a supplementary back and side, the supple- (hispose(l across the line of the keel of the ship an(l mentary back being fitted with the faced ring before the circulation of the con(lensing water is produced l)y referred to, for relieving the back pressure, the supple- mechanical means, and takes place within the thin mentary sides and ends being perforated with aper- metal tubes, whilst the steam to 1)0 condensed is tures of any convenient size or form to admit the brought in contact with the exterior surfaces.

A still used for the generation of fluoric acid, which is minmeb used to produce figures on glass by corrosion, exploded, and Mr. Whitehonse, the senior partner, received such injuries from it, as soon terminated his life. Fluorie acid is exceedingly d~ ngerous its fumues are sumffocat- ing, and, imi the liquid state, it burns flesh almost like fire.

Long- mai(l for treating pyrites and other ores as follows The ores are first ground so as to pass through a sieve having about 100 holes to the square inch. They are then introduced into a furnace where two processes are constantly being carried on with the same heat. The first part of the process consists in tile calcining of tile pyrites, so as to reduce tile sulphur in them to about five per cent; and secon(liy, tile decomposing of these calcined ores by comn~on salt. Flie groun(l ores, when first placed in a chamber of the furnace, evolve sul- phurous acid, which passes off into another chamber, where it is converted into sulphuric acid by being brought in contact with a proper quantity of oxygen. These calcined ores are now witlldrawn, mixed with about five per (ent of common salt, then placed in another cleunl)er of tile furnace, where they are re- duced. After this they are smelted to obtain eltiler the iron, copper, silver or tin which may be in them. This process would iC very useful for California pyrites, if fuel were cileap in that State. CARTRIDGES FOR naaacii LOAI)ERS. A patent for a enrtri(lge nla(le with gun cotton, coverell Witil a skin of collodion, has been obtained by J. Macintosh, London, England. It is statell to be impervious to moisture; it rea(lily ignites with a per- cussion cap and leaves no residue after firing. Gun cotton ignites so rapidly that it is very liable to burst a rifle or cannon. Were this not the case, it would be preferable to gunpowder for firearms. PURIFYING COAL OILS. A pateut has recently been taken out in England by W. 11. Bowdich, of Wakefield, for a peculiar method of purifying coal oil. In a proper vesselcalled a purifier-he arranges it with a tray on its upper part, which can be heated to a proper temperature. On this tray is placed sifted lime (hydrated peroxyd of iron may be use(i, hut clay is preferred) and pounded clay, and these are slightly raised above the boiling point of the oil. When the purifying material is at the proper temperature, tile oils are to be sent into the lower part of, and diowed to pass upwards through the ilot puri- fier, after which tiley are to 1)0 condensed in the usual way. Care must be taken not to send hl the oils too rapidly. Care is also required to prevent the tar liberated by this process from passing over with, and becoming absorbed in, the pllrified oils. The tar will not pass with tile purified oils, if the purifying material be not saturated with oil; but it will pass if the purifying material is saturated. It is requisite, therefore, to supply the hot purifier with tile coal oil slowly, so that the purifyin~ material may not become saturated. rThe purified oil will then be of good color. The oil passing from the purifier an(l through the condenser should he received ulto a glass vessel at intervals and examined; and, if found colored, the quantity passing through the ilot purifier 8110111(1 be lessene(l. If witil a slow current tile (listilled oil be colored, the hot purifier sllould be charged with fresil purifying mate- rial. The purified oils absorb some part of tile gases produced in the process of purification, which gases evolve more O(lOr than tile oils Ilave naturally. Such gas may be removed, an(l the smell of the oils im- proved by washing tileul witil a solution of caustic soda or potash, oul subsequently witil water. The quantity of removable matter is so small that a weak solution of alkali is sufficient, and tile oils witilout it are so good that probably the wasiling will not be thought necessary, except where smell is of great im- portance. Experience shows that a quantity of heated purifying material, equal to about a fourth of the weight of oil to be purified, gives an excellent result. The claim is for the passing of coal oils through slacked lime, or pounded clay, or hydrated peroxyd of iron, heated above tile distilling pohlt of tile oils, as de- scribed, by which treatment tar and sulphur com- pounds are removed, and the oils are rendered whiter and free from disagreeable smell. STEAM NAVIGATION ON ENGLISH CANALS. It is ratiler singular that steam navigation on Amer- ican canals should ilave been unsuccessful, as described on page 39 of the present volume of tile SCIENIIFIC ~MERIcAN, while in England it ilas become so success- ~nl as to reduce the cost of conveying freight no less than 25 per cent. Tile Grand Junction Canal Company, which formerly used to tow their boats with horses have (lispensad with animal power, and now use steam alone. There are 5,000 miles of canal in Great Britain representing a capital of about $200,000,000, and since the adoption of steam as the propelling agent, the traffic increased inst year 25,000 tuns. The most pecu- liar feature in the steamboats which are now employed by the Grand Junction Company plying between London and Bi~mingham or Manchester, is an improved form of screw propeller, called the waggle tail, which has the advantage of keeping all the disturbance of the water immediately behind the stern of the boat, instead of spreading it right and left. The effect of this im- provement is at once to secure the canal banks from being damaged by tile wash and to econonlize tile motive power. FRENCH RAILROADS. Tile French government is reported to be contem- plating the purchase of all the railroads in that country. An article in the Revue del deux Mondes, in opposition to tilis centralizing project, points out that tile Russian Austrian and Belgian governments, which all began by constructing railroads, have found it advantageous to get rid of most of them and encourage private enter- prise. Already the Frellch government monopolizes the manufacture of arms, gunpowder, naval architec- ture, public works, tobacco, salt, the conveyance of private messages by telegraph, the conveyance of small parcels, and controls the management of forests. It is the conservative or rather distrustful system which has caused France to be surpassed in railway extension, not only by England, but by Germany and Belginln. France is in the third rank, as regards the mileage of railroads executed or authorized by decree ; in the seventh rank in respect to the amount of her popula- tion served by railroads; and in every point inferior as conlpnred with England and Belgium. As regards commercial facilities and the general illduStry of the people, Louis Napoleon llas been a great patron of tile industrial arts. He must beware, how- ever, and not curtail illdividual effort by adopting a grand centralizing system.. The ~reat advancement and prospelity of the United States are principally due to intelligent and general individual effort. Supposed Cancer Speedily Cured. The Denial Cosmos contains an account of a case by J. L. Suesserot, M.D., relating to an aged lady who had suffered for such a length of time from a large ulcer OIl the inside of the lower lip that it was at last held to be malignant cancer. The exciting cause of this was the protruding apices of the roots of the central lower inci- sors which ilad escaped the notice of the attending physi- cian (a gentleman of acknowledged ability in his pro- fession), because of the coating of tartar, which rendered their appearance very similar to that of the illeer. Dr. Suesserot says respectin0 it: Prompted by a desire to benefit the patient, and at the same time demon- strate the advantage of a dental edneation, I was induced to commit the unprofessional act of oper- ating before the invitation was extended. No regular instrument being at hand, I called for a table fork, antl, in a much shorter time tilan the writhlg of tills ilas consumed, I relieved tile greatly distressed patient of a disease which she had expected would very SOOll ternlinate her existence. Nearly all of the alveolar margin Ilaving been absorbed, by plaeing a prong of the fork lander the protruding lower end of tile root, the operation of evulsion was readily per- formed; and by the removal of that which had become a foreign substance, the diseased condition of the lip, as well as all the surrounding parts, IYRS speedily removed. As this is not DII isolated case, it would be well for the cause of humanity were the dentist more frequently called in consultation; tile (liseases of tile teeth and their surroundings being his special province, many morbid changes which too often escape the notice of the physician, or are considered by him of minor importance, might he detected, and disastrous results prevented. SunlusssoN TO IMPROVEMENTS. In our time wllell science and art are making such rapid strides that almost every day startles us with the announcement of a new discovery calculated to annihilate time, or increase the productiveness of labor, mechanics often find themselves encroached upon in tileir occupation, and instinctively take a stand against the revolution intended. Nothing can be more natural, or, on calm reflection, more completely hopeloss. The consequence is inevitable. The mechanic must submit, and expect to receive his reward indirectly and in the course of tinle. -Shoe and Leather Reporter. AMERICAN NAVAL ARCHITECTURE.

The application of india-rubber to waterproof garments by Charles Macintosh was the first practical adapta- tion on a large scale either here or abroad and the immense number which were sold proved fully their appreciation in- the public. In 1880, the first attempt at overshoes in this country was made by Thomas Ilancock, who took out a patent in that year for a composition for coating linen or cloth, or moulding into shoes. These, however, were a failure for the same reason that all manufactured in(lia-rubber goods had hitherto been found deficientthey would not withstand the action of the atmosphere. There was evidently a goal not yet reacheda grand secret which must be discovered crc success should fully attend the manufacture, or the value of the material be fully proved. It~s application, however, to various useful purposes was constantly going on, and both in France anil this country, as well as in America, large sums were expended in perfecting machinery for masticat- ing, spreading, and otherwise preparing the gum. One singular application was made, in 1840, by press- inn it into blocks combined with sawdust and finely- broken stone, for paving roads. This patentfor it was ma(le the subject of onewe fear (lid not prove remunerative to the inventor, as it does not seem to have ever been turned to practical account. Several patents were also taken out for cutting in(lia-rubber threa(l, aud applying it woven with silk and cotton to various rposes where elasticity was requireda biauch of manufacture which still exists as one of the most successful of its al)l)licatious. The year 1848 saw the intn)(lilctioli, however, of the long-sought-for change, by which the gum was ren(iere(l inadhesive and elastic alike under the influ- ence of heat or cold. ~fhe merit of this invention, about which there has been much litigation, is unquestionably due to Charles Goodyear, although a patent was taken out in this country by Thomas Hancock prior to Goodyear s, which bears date two months later. Reasons for this ae, however, given in the case of the American which are fully borne out by facts. Vulcanization, produced, as is now well known, by the action of sulphur under the influence of heat, ranks amongst the most important di Overies of the present century, and the discoverers have each, in their respective countries, reaped the reward of their labors by large returns received under patents granted to them for the process. The establishment of the india-rubber manufacture in America, though dating later than that of England, has reached greater perfection, and is more thoroughly understood than in this country. The first manufac- tory of any consequence was started there in 1882, and was called the Roxbury India-rubber Company, whilst here the first, we believe, was that of Mr. Chmrles Macintosh, who conunenced in the year 1821, more them ten years l)revioils. Charles Goodyear was born in New Haven, United States, in December, 1800, and for upwards of thirty years was engaged with his father and brothers in the hardware and clock business at Connecticut and Phila- delphia. During this time, indeed in his early days, commenced the (levehOpment of that inquirhig and in- ventive genius which afterwards led to such great re- sults when his attention was turned to india-rubber. Many ingenious and useful inventions in connection with his trade added to the celebrity of the firm, which then held a position as one of the first hardware con- cerns in the United States. From extended credit and heavy losses, however, the firm were obliged to suc- cumb, and young Goodyear, who had charge of a re- tail store at Philadelphia in connection with his fathers factory, was heft, after repeated imprisonments for debt, with no very bright prospects for the future. It was at this time that accident drew his attention to the decomposition of india-rubber goods, and he was told that if any means could be discovered to prevent it, a very large sum of money might h)e realized by the invention the numerous manufactories then existing, an(l the large sums of money invested, being placed in jeopardy by the goods hieing thus rendered unsaleable. He imme(hiately turned his attention to this point, and from that time to the (lay of his recent death, through good and evil report, in wealth and in pov- erty, in prison or palace, the sick lied or the traveling 67 carriage, he never ceased to give the one point of ren- dering india-rubber a perfect material his whole atten- tion. The perseverance which induced this deserved success, and in 1889 lie was rewarded by- the disco very of vulcanization. His first attempts were commenced in his own cot- tage, where, with the assistance of a New England wife, who was his only friend through many struggles an(h (lepressions, he succeeded in making a few pair of overshoes, as lie thought. of a superior kind to those ma(le by the companies then in existence but, alas they proved like the rest, and were destroyed after a short exposure to the air, indeed sooner than those without his improvement. On lookin~ at his stores, when about to take them into the market, he found them one mass of melted gum. This was a sad failure, and the furniture of the cottage had to go for the sustenance of his family. Cast down, but not undaunted, he put his family in a boarding-house, and set off for New York to continue his experiments. Here he met with a friend to give him lodging and a chemist who found him his drugs. Tie went to xvork again with magnesia and lime, and produced some in- adhesive materials, which, though apparently at the time perfection, turned out, like the rest, failures though he exhibited and obtained a medal for the im- provement at the fair of the American Institute. While experimenting with lime lie washed his mate- rial with nitric acid to remove the lime from the sur- face, and discovered what is known as the acid-gas process, which he patented and found of great value. During the winter of 188687 he entered into partner. ship with a Mr. Ballard to make goods on this plan, and they took steam-power in Bank-street, at the sanic thac making arrangements for occupying a large factory- on Staten Island that had been aheady tenant- ed liy a corporation in New York for the manufacture of india-rubber goods, but which, from their inahillity to surmount the difficulties of the business, had been closed for some time. The mercantile (lisasters, how- ever, of 1837 included the friend who was to find the capital, and lie was left without the means of carrying forward his plans. Again was the little home broken up, and he had to seek the assistance of a brother al- most as poorly off as himself. Located on Staten Island, he was allowed admission to the machinery of the closed factory, and there made a few goods to ob- tain his daily bread. These, though the general lot of inventors, were hard trials to be borne. The heavy losses whicli had been incurred by all who had invested in india-rubber stock made it utterly impossible to induce any one to assist him. He found the same state of things at Boston, and, taking some of his specimens to Roxbury, Mass., he found no better encouragement there, that company having entirely abandoned the manufacture. He here, however, also obtained access to the machinery, and still went on struggling for success. In 1888 his at- tention was first drawn to the use of sulphur by Mr. Hayward, a gentleman connected with one of the in- dia-rubber companies, who was using his solvent im- pregnated with it as a dryer. Goodyears notice being thus drawn to it, and seeing a value in it which Hay- ward did not, he purchased the patent which had been taken out at his suggestion, and which simply claimed the using of sulphur as (lescribed, neither party having any idea of vulcanization afterward dis- covered by Goodyear. During this time he issued several licenses for work- ing under his acid-gas and solarizing process, which was thought a great improvement, and which brought him in a few thousand dollars. His fortunes seemed in the ascendant, and he manufactured large quanti- ties of fancy articles, and obtained an order from the government for a number of mail-bags. With all the goods lie was now making he mixed large quantities of pigmentschromes, white lead, and vermilionbut without chemical knowledge, he was ignorant of the effect of these metallic colors on the india-rubber after under~oing his acid-gas process, and the result was, that the whole proved a ruinous failure, all the goods decomposing within a short time after their comple- tion. Everything he possessed was again brought to the hammer, and his aged parents, whom he had been for some time supporting, together with his own fam- ily and two younger brothers, were left penniless. Four years had been spent in experiments, all of which had proved fruitless, and it was generally agreed by those who had hitherto assisted him that the man who could proceed further in a course of this sort was fairly deserving of all the distress brought upon hihe - self. No hope could be looked for in that quarter. The only advice he got was to return to the hardware business even his licensees, dliscouraged by their fail- ures, wouldi not grant him any assistance. The india- rubber trade in the United States was at its lowest ehsb, the ruinous losses which had fallen upon those who had hinvested their money- in it making it a public calamity. He had, however, made it his leadhing star, and no nersuasions could make bins give it up. Be- diucedi to poverty and the pawn-shop, he is described as being recognizable as a man who has on an india- rubber cap, stock, coat, vest, and shoes, with an india- rubber purse without a cent of money in it an en- couraging picture for those to whom lie applies for help. But fortune was in store for him. One day ac- cidentally bringing a portion of rubber mixed with sul- phur, which he had in his hand, in contact with a hot stove, he found that it had undergone a change such as he had not before noticed, and following up the ex- periment for some months alone in the factory at Woburn, lie discovered the process which makes it proof against cold, and the usual solvents, and, as Ise hsimself says, he felt amply repaid for the past, amsd qisite indifferent as to tise trials of the future. Perse- verance had met with its reward, and the future, though not bright at first, and often clouded over by trouble, eventually bore out his Isopes to their fullest extent. Not to follow too closely Isis chiequered career, we may Isere state thsat although he at once pateisted his hivention, tsvo years elapsed before Ise could get any one to assist him in bringing it before the public, such was the general aversion to any more experiments with what Isadi hitherto provedi so disastrous a faibire a state of things so unfavorable to the promulgation of tlse dhiscovery as cams well be imagined. The intem-- val was occsspied Isy making various imisroveissents, life being sustained by means of diverse loans of five and ten diollars, presents ef barrels of flour frons symss - patliizing friends, pawning even his childrens school- books, and other shifts with whsich poverty is famihiam-. He felt he had nosy, Isowever, grounds of assurance which had never existed with regard to previous mi- provements. TIse (liscovery was made in wiister, andi the specimens dlldl not harden. Sumumer retum-ned and they did not soften by heat. Swallowing Indigestible Substances. Dr. Read exhibited at the & ston Society for Medical Improvement, a dpsant.ity- of stones varying in size from that of a pea to tlsat of a cherry, whiels lsad pass- edi through the intestinal canal of a boy sevems years 01(1. Havimsg seen one of the performers at a circus swallow, or pretend to swallow stones, lie resolved to follow his example, and in the course of one afternoomi lie swallowed si ty;fonr, the usnited weight of which was a little more than nine ounces, and which filled an eight ounce bottle. On tlse next dlay the stones could be felt tlsrouighi the walls of tlse abdomen, arid, uspon percussion, could be heard to rattle, lust produced no iisconvenience. Castor oil was administered, and thsey were readily ex- pelled. At the same usseeting, tue proceedings of whuicis are reportedl in the Boston Medical end Surgical Journal, Dr. Pyher said that it was a common thing for patients at the MeLeams Insane Asyluiss, to swallow small objects, suich as pieces of glass, coal, stone, thimbles, & c. Recently a woman swallowed a crochet needle whichs was voided without inconvenience. Among sonse of the patients was a cusriouss propensity to swallow toads, and there is now in tlse Asylum a man who Isas swal- lowed half a dozen live toads without injury. Dr. Adams stated, that in a case of obstruction of the bowel, which followed the eating of a lam-ge quan- tity of cherries and swallowing the stones, the nurse collected and cousuted one thousand end seventy-seven cherry stones which were evacuated. Dr. Agnew, of this city, lsas in his private collection a pseparation of the stomach and intestines from an insane patient, in which are accuniulated an extra- ordinary variety of foreign materials, among whiels we recollect having seen long strips of bamsdage, sinus- penders, portions of clothing, buttons, & c. - A soasn cake of gold, worth nearly 50,000, has been sold to the Bank of New South Wales, and the quartz reef from which it was obtained will produce $150,000 a year for many years to come. ~e ~dentifi~ ~rnevi~n. ROMANCE OF THE STEAM ENGINE. ARTICLE VIII. AMONTONSJ?IRE WHEEL. After Savery, the next inventor who produced a pe- enliar calorie motor was Guillaume Amontons, of Paris, who was so deaf that he was thereby deprived of the sweets of social intercourse except with his own family. He early exhibited a taste for mechan- ics and, as is mostly the ease with young enthusiasts in this line, his first efforts were directed to invent a perpetual motion. His experience soon taught him that he was in search of an impossibility, and he then levoted his attention to other projects, among the rest a hot air engine entirely different from any that had preceded him. Tbis machine was called a tire wheel by Amontons, and is described as beiug operate(l by the action of heated air forcing a quantity of water up one si(le of a wheel and producing a ro- tary motion liy its differing weight from the other side. Ainontons appears to have been partial to expansive air as the motive agent of his engine, represented in section l)y tbe annexe(l Figs. 1 and 2. This fire wheel, as described by its inventor, consists of two concentric rings connecte(l and communicating with small pipes, 1, 2, 3, 4, & ~. ~ outer ring of the wheel is divided into several compartments, a, b, c, d, e, f, & c. Tbese were closed so as to have no connection with one an- other. The inner ring is~divided into the same num- ber of compartments, a, b, c, d, e, f, & c.; each of these communicates with the adjoining chamber by a hinged valve opening only in one directionupwards. Al- though the two rings and their series of compartments are placed at a (listanee, each compartment of the one communicates with a corresponding division of the other hy small pipes, 1, 2, 3, 4, & c. The wheel is so placed as to have one side of its periphery exposed to the action of a fire, and the other side is immersed in a cistern, y, of cold water. Four or five of the lower chambers of the inner series are filled with water. A lire is made in the furnace, z; this heats the air in the a, of the ai chamber, the outer series, r of which, be- coming rarefied, flows through the pipe, 1, into the chamber, a, of the inner series, an(l presses upon the water which it contains and forces it upwards into the (livisions on the side of the wheel nearest the furnace, which gives it a preponderance and causes it to de- seen(I. The cell, a, is now in the position at first occu- pied by b, andc is in that where it begins to enter the cistern; the air which is contained in the divisions which had been heated now being brought into con- tact with the water, it is condensed, and continues so until, by the revolution of the wheel, it is again bought, in its turn, into contact with the fire of the furnace. Nothing can be simpler than the hypothetical action of this mechanism; its effect was, as usual, not under- rated. The wheel was 12 feet in diameter, and the cells were calculated to contain 750 cubic feet of water, and an entire revolution to be made in about thirty- five seconds. This ~reat weight, applied tangentially to one side of the wheel, was to give it a continuous preponderance, which was calculated, very minutely, to equal in effect the power of thirty-four horses, or two hundred and thirty-four men. Throwing the practical merit of this mechanism to- tally out of the question, the combination is exceed- ingly meritorious; and looking to the time of its in- vention, and the perfect novelty of the idea, it has many claims to a more favorable consideration as a first thought, than has usually hecn awarded to it. That it presents glaring defects cannot be denied; but had length of years been alloted by Providence to its amiable projector, the same ingenuity which first traced the outline might have effectively supplied its (leficiences. A negative proof of its merit is, that it has been the type of several attempts at the construc- tion of steam wheels among later mechanics. While Amontons, in France, was engaged in his steam wheel, and Savery, in England, had achieved so brilliant a triumph, Papin was again exerting himself at Marpurg, in Germany, to bend the same powerful agent to the use of man ; as if the three nations of Europe, which had made, says Belidor, the greatest advances in science, were each anxious to furnish a learned man to participate in the glory of so fine a (liscovery. ELECTRICITY AND SOME OF ITS PRACTICAL APPLICATIONS. ARTICLE \T When two electrodes of carbon are brought into con- tact with each other, or an electrode of carbon is lowered upon mercury, there is produced the well- known electric light. This light, which, for power and beauty, excels all other artificial luminaries, and is equalled only by the sun, is produced by a stream of small particles of carbon, which are transported from the positive to the negative electrode, where a portion of them is found piled in an irregular heap, and some- times crystallized. These particles are kept at a white heat by the battery, and while in that state give an in- tense light. Some idea may be formed of the brilliancy of this light, from the fact that two chemists, while experi- menting with it, brought it too near their organs of vision, and, as a consequence, were confined to a (lark room for several days, and barely escaped with their eyesight. Any such occurrence may be avoided by wearing green spectacles, which, although they prevent injury to the eyes, allow all the motions of the light to be studied, as well as its general charac- teristics. The flame takes the form of an arc when the electrodes are separated, which separation may he effected in a greater or less degree, according to the power of the hattery. When the electrodes are separ- ated nearly to their farthest limit, more light is given off than in almost any other position; and to effect and maintain this separation continuously is a subject to which much attention has been and is being given in Europe, although it has attracted but little atten- tion in this country. The positive electrode wastes away with a rapidity controlled by various circum- stances, the worst varying from one-third of an inch and upward per hour. If the exact waste can be ob- tained, one of the electrodes can be fed forward by means of clockwork, and the interval between the two kept of an uniform length. Another device is to have the current itself regulate the motion of the positive electrode; and such an arrangement is, if well con- structed, much the best, as it will accommodate itself to a current of any power, while, if simple clockwork is used, a new adjustment must be made for every im- portant change in the battery. One device is like the old fashioned steam engine, opening a port of the same size for each stroke ; the other like the modern en- gine with its self-adjusting cut-off, varying the use of its port according to the pressure and the amount of work to be done. The current required for the pro- duction of the electric light maybe either one of great quantity or of great intensity. A current of quantity will produce a wide and short arc of flame, E E, while a current of intensity will produce a long and narrow arc. From this, it is evident that the battery best suited for ~the production of this light is ~~-one which gives a current both of intensity and quantity, and such a current is pro- duced by a number of alternations of large cells. One of the best batteries for experimenting with this light is Daniells, twenty cells of which (the zinc being seven inches in hight and two in diameter) give a cur- rent sufficiently powerful to exhibit the light upon a small scale; but with from 50 to 100 cells, a magnifi- cent light will be produced. Bunsens battery is chiefly used for this purpose, and when well managed it is, for the same number of cells, far superior to Daniells, although very expensive and troublesome in its working, and liable to the objections before given. A series of 40 cells of this battery, recently exhibited in Paris, produced a light equal in power to 3,500 wax tapers! The battery, though very convenient for pro- ducing the light, has been superseded, to some extent, by a machine in which no acids or liquids of any kind are used, the current being induced by permanent magnetism. Before proceeding to a description of this important piece of apparatus, it will be necessary to mention a 4 5 12 few of the principles of induction. The subject of induction should pro- perly be considered by itself, but it is so intimately connected with that of the electric light that we shall con- sider it in this place. A number of years since, it was ob- served that if a current of electricity was made to traverse one of two par- allel wires, a wave of electricity was produced in the secondary wire, and in the opposite direction to that in the primary wire; and that when the current was broken, another current was produced in the same direction that the primary current had flowed. In the cut, S represents the secondary wire, and P the pri- mary. In 1831, it was observed by Faraday that an electro- magnet possessed the same power. The cut represents a sectional elevation of such an arrangement. ~S N S is a bar of soft iron, around which is wound the primary or battery wire; S S is the secondary coil. In this case, both the p1imary and secondary currents flow in the Fi~I1 same direction, because the secondary current A is induced, not by the primary one but by the eleetro-magnet. The moment that the current ceases, there is induced another current, opposite in direction to the first. About the same time that he made this discovevy, Faraday also found that permanent magnets possessed the same power of induction. The cut represents a device by which a spark may be oh- tamed by the use of a common horse- shoe magnet, of moderate power. S ~s~ N represent the poles of the magnet, AT and N S the extremities of its arma- ture. Around this, several feet of in- sulated wire are coiled, and its two ~LJ I ends brought as near as possible to each other without their touching. This being done, a faint spark will be seen whenever the armature is separated from, or brought in contact with the magnet. Salt and its Offices. Some modern agricultural writers have (bolibted the necessity of giving animals salt. The following re- marks as to the effect of salt upon health, by Professor Johnston, may be relished by those who still put salt in their own puddings, and allow their cattle a little now and then: The wild buffalo frequents the salt licks of Northwestern America~ the wild animals in the central parts of South Africa are a sure prey to the hunter who conceals himself behind a salt spring; and our domestic cattle run peace- fully to the hand that offers them a taste of this delicious luxury. From time immemorial, it has been known that, without salt, man would miserably perish; and among hor- rible punishments, entailing certain death, that of feeding culprits on saltless food is said to have prevailed in barbar- ous times. Maggots and corruption are spoken of by an- cient writers as the distressing symptoms which saltless food engenders; but no ancient or unchemical modern could explain how such sufferings arose. Now we know why the animal craves saltwhy it suffers discomfort, and why it ultimately falls into disease if salt is for a time with- held. Upward of half the saline matter of the blood (57 per cent) consists of common salt, and as this is partially discharged every day through the skin and the kidneys, the necessity of continued supplies of it to the healthy body becomes sufficiently obvious. The bile also contains soda as a special and indispensable constituent, and so do all the cartilages of the body. Stint the supply of salt, therefore, and neither will the bile be able properly to assist the di- gestion, nor allow the cartilages to be built up again as fast as they naturally waste. DIMINISHEB SLAIJOIITER.-ThO number of hogs slaught- ered this season at Louisville, Ky., and in its vicinity is 194,797, or about 40.000 less than at this time last year.

J. Haine, of Strood (pat- ented August 14, 1860), has for its object improve- nients in the manufacture of driving straps. ror these purposes, the material (generally leather or hides) is cut into narrow strips or fillets, each strip or fillet being of the thickness of the intended driving strap, and these are placed side by side with the cut edges of the leather or material com~xg to the upper and under surfaces of the intended driving strap, until the de- sired width of strap is obtained. In arranging the strips side by side, care is taken flint the ends of the several strips or fillets come at a distance from each other, so that the strips or fillets break joint, in order that the strap many not be weaker in one part than in another. In order to connect together the several strips thus laid side by side, the several strips are pressed together and holes are bored through them at intervals from edge to edge of the driving strap; the strips may then be fastened together by introducin~ lengths of iron, copper or other wire, having a he~ formed at one end through the holes, and then turn- inn over, clinching or riveting the other ends of the wires. Or the several strips may be united together by screws screwing through the holes in the several strips, the screws being screwed into the holes alter- nately, first from one edge of the strap and then from the other, so that the heads of half of the screws will be on one edge, and the heads of the other half will be on the other edge. ~1he several strips may also be connected together after the holes have been made through them, as above described, by nieans of copper or other wires, two wires being employed for this pur- l)ose, arid both wires being passed in opposite direc- tions through each hole, and each wire, after it has passed through one hole, being bent round and passed through the next hole, and so on; or, in place of wire being employed, the several strips may be sewed to- gether, as described, by means of twine or any other material. In place of the holes being made in the several strips of leather after they have been placed side by side, each strip of leather may separately have holes made through it at regular intervals, so that when the stril)s are l)lmite(l side by side the holes may correspond, and then be fastened by any of the before- mentioned means. Ihese bands may be made of any re(luire(l length, without laps or cross joints their thickness being uniform from end to end, there are no weak places; and all unequal strain being avoided, they work smoothly and perfectly straight. The inventor states that these bands can be made of any thickness or strength required, without sewing or riveting, thus avoiding the liability to ripping which so frequently occurs in the commoii straps. By this mode of work- ing the strap on the edge of the leather instead of on the flat, all chance of cracking the grain of the leather, and thereby weakening the strap, and ultimately breakin0 it, is avoided. It is also elahued as an ad- vantage that they may also be use(l much slacker than the common strap, as the result of placing the edges of the leather in contact with the surface of time drum or pulley insures a much larger amount of adhesion (or hugging, as it is technically terme(l) than is pro- duced by the ordinary method. GRANTS IMPROVEMENTS IN BREAKWATERS. We find in the London Mechenics Magazine, the de- scription of a newly-invented breakwater, which ap- pears to be so remarkably cheap in its construction, that we transfer the description and illustration to our columns Mr. J. Grant, of Glen Grant, Moray county, Scotland, has patented certain improvements in floating break- waters. ills invention consists in forming a breakwater of any required number of apparatuses constructed as hereafter described. Each apparatus is formed of a frame made to carry a number of louvre boards or plates; the main part of the frame is coniposed of two beams brought close together at that part which is to become the bottom of the apparatus. As the beams are car- ried upward they diverge and make a conical-shaped frame ; the louvre boards or plates are fitted at an angle into and across the beams. The beams have fixed on them buoys to increase or insure their buoy- ancy. Each separate apparatus is moored to a screw- pile, a block of stone, or other mooring by its lower end; the upper end carries one or more projecting pins or studs, and iron rods, formed at both ends with eyes, are passed over the studs, to connect the appara- tuses to each other, prevent their coining in contact, and unite any desired number of the apparatuses into a complete breakwater. Each apparatus floats verti- cally, or at a greater or lesser angle to the horizontal line, and is partially submerged. Each of the appara- tuses is capable of independent play, and the waves, striking against the louvre plates, are broken, and the water becomes comparatively still inside of the break- water. In the accompanying engraving two of these appara- tuses, connected together in the manner just described, are shown. The beams, formin~ the frame of each apparatus, meet and are fixed together at their lower part. Across theiii are louvre boards, inserted in the beams, one above the other, as shown. The buoys are secured to the frame, one at or near its upper part, and f lie other near the bottom thereof. A ring is bolted to the lower end of the frame, whereby it may be connected to a niooning or anchor. At the top are connecting rods; they are made with eyes which pass over studs on the upper part of the frame, where they are secured by bolts, pins, or otherwise. Any number of these apparatuses may be connected together, and moored in a straight line, in a curve, or in amiy other ~n ure according to the part to be protect- ed or the extent of water to be mAe smooth. In some cases the connecting rods may be dispensed with. LEAVES or PLANTSAutumn leaves by millions rot in heaps unheeded, and yet each one a microscopic wonder of contrivance.

Magazine. THE SCIENCE OF COMMON THINGS. NUMBER Y. BONES AND ROCKS. In our examination of the beefsteak last week, we omitted all mention of the bit of bone in it. I wish to call your attention to this, as it contains a sample of the only remaining class of the simple elements. You remember that there are 62 elements at present knowmm, 47 of which are mnetals. With most of the metals which occur in any considerable quantity you are fami- liar; the four principal organic elements I have de- scribed; and now there remains a small class of other substances which are worthy of our attention. One of these is sulphur or brimstone, and another is phos- phorus. It is the latter which is contained in bones. A considerable portion of bommes, as they exist in livimig badies, consists of animal matter, but after this is re- moved, the remaining partdry bonesare the phos- phate of lime. They are composed of phosphoric acid and lime. If they were composed of simple phos- phorus and lime they would be called time phosphuret of lime, but combimmations of phosphoric acid are called phosphates. Phosphorus is extracted from bones and used, among other purposes, in the manufacture of friction matches. When warm it is soft like wax, but h)rittle when cold. If perfectly pure, it is colorless and transparent, but generally appears yellowish and translucent merely. Do you say that the phosphorus which is used for making matches is obtained from bones? It can be procured from other sources, but it is principally obtained from bones. There is one other element that exists in large quantity, which you never see separated from its compounds except in chemical laboratories, but with the oxyd of which you are veiny familiar. This is silicon, and its oxyd is silex. You see it as flint and as quartz rock. It also forms a part of many other rocks, amid is believed to constitute a larger portion of the solid crust of the earth than any other element, with the single exception of oxygen. Excepting silex, almost all rocks are oxyds of metals; indeed, some chenmists call silicon a metal, but it has none of the properties of metals. It is a dark brown powder. And are these all of the simple elements besides the metals? No; there are two more which I will mention to you in this connection, and that will complete our examination of the simple elements. One of these is iodine, which, from its changes under the action of light, is used extensively in photography; indeed, it may be regarded as the corner stone of photography. The other element is the great bleaching substance chlorine. Table salt is composed of chlorine and a metalsodiumand is therefore known to chemists as the chloride of sodium. And this brief account will give you a pretty good general idea of the simple elememits of which all the substances that constitute tIme earths, the air and the water of our globe are coni- posed. We will examine some of these mesa in detail hereafter; there are, especially, some facts in relation to the metals which I think you will find interesting. Locomotive Explosion. A serious boiler explosion took place on the Hudson and Boston Railroad on the 29th of December last. The locomotive Henry Grey, while standing at Claver- aek station, exploded her boiler with tremendous force, throwing the smoke stack upright in the air, and scattering the fragments of the boiler far and near in evemy direction. One piece unroofed a barn; an- other damaged a building in the vicinity; a third was thrown a quarter ofa mile upon a high hill, through the window of a seminary. The cylinder past of the boiler was blown open for the whole length, and the flues and machinery under it were twisted and bent in every conceivable direction by the force of the steans. Even the rails of the track were bent almost double, but, strange to say, the engineer and fireman were un- hiurt, though they were both on the engine at the time. Time boiler was lmmmilt by Chapin & Bemis, of Springfield, Mass., and had been in use about four years. On examination, it was found to have been of good iron, but the plate much thinner than usual in locomotives. The engineer states that there was about 90 lbs. pressure on at the time. The report was dis- tinctly heard a distance of four miles. The London Times---A Glance at its Machinery. 1he London Times is the recognized organ of British public opinion, and is beyond all question the most ably edited amid influential journal in the world. Its editorials are essays upon the great political, literary and social topics of tIme day, and so powerfully writ- teim that they have been collected into books; wimile its correspondence from all parts of the world is an inex- Imaustible source of information.

It is truly soumething great and wonderful there is nowhere in Frammee anything of the kind to esiiial it. At time startimmg of time paper in 1791, time Times consisted of only a simmgle page, and was printed by a band-press, wlmich struck off one side of two hun- (Ired sheets per hour. In l~14, Kmnig made a press whiclm struck off 1,800 simeets. In 1827, Applegarthm, aided by Courier. coimstructcd a new one, on which 1,000 to 5.000 copies could be printed. In 1828, tIme same Appiegartim established imis famous vertical ma- chine, which I examined. amid on wimich 10,000 copies per hour are struck off. Simmee 1828 tIme muanagers of the Times have erected another niachinine, with horizon- tal cylinders, which strikes off ciglint copies at once or about 12,500 per hour. These two presses, which make while at work a deafening noise, and whmiclm can be stopped at a mmmommments notice, are muoved by a steam emmgine of 45-morse pow-er. Adjoining the room iii which is the boiler is a closet containing white marble bathing tubs intended for time workmen in time c stablislmmnent. Timey cost ninety guineas. A compositor omi tIme Times must have passed an cx- munimmation showing thmat he can set at least 40 lines of 5th letters or abommt 2,240 letters per hour.
