To WILLIAM MITCHELL, Surgeon, late of Ayr, now in Edinburgh; for an invention of Articles, of home Growth and Produce, for the Manufacture of Soap. T is a strong jelly, preparable from the skins and coverings of all animals, but more particularly the offal of skins after they are limed, commonly called screws, to which is added carbonate of soda. It is prepared and used in the following manner: viz. Take any given quantity of screws, say them asteep in cold water for two days; after that, put them into a boiler with five or six times their weight of cold water; boil them, with a slow fire, until all the skins are dissolved; place a cask upon the side of your boiler, which has a cork fixed four inches from the bottom of the cask, at the height that the liquor will run into the boiler; over which place a search or

strainer, made with a piece of thin cloth,

fastened to a square frame of wood; run your solution into the cask through the strainer, and allow it to remain in the cask five or six hours, in order to let the sediment fall below the cock; after that, run it into the boiler, and boil it slowly, till it comes to be a strong jelly, which

---- - - --

may be ascertained by taking out a small quantity, and cooling it, or in the proportion of three parts of water to one of the screws, or "stronger in proportion as you mean to use it in larger or lesser quantity among the soap; to which solution add from two to ten per cent, of the carbonate of soda. The solution being thus prepared, and the soap upon which you are to operate being ready for casting, you proceed to use your solution in the way here directed. You have a measure that will hold the quantity that you mean to put into the frame; if only one hundred weight into the frame of fortyfive inches, you take a tub, into which you put a small quantity of your solution to be mixed with a little soap, so as to make it as thick as will prevent it from running out of the joinings of the frame; which being done, pour it into the frame, and so on with the rest till you have the whole in the fame. Then fill up the frame with the soap, and mix or crutch it well till it is pretty cold and stiff; or after the soap is finished and ready for casting, the niger or refuse might be completely pumped off, the mixture might be put into the pan, and well mixed with the soap, and cast in the ordinary way;

but the mixing in the frames is the preferable way: from ten to twenty-five per cent, may be used, according to the quantity of the soap used. From the hardening quality of this saponaceous jelly, whale oil and palm oil may be substituted in the room of tallow, and good hard soap made at much less expense. -oMr. WILLIAM SUMMERs, of New Bond. street, for a Method of raising hot TWater from a lower to an upper Level jor Faths, Manufactories, and other austful Purposes.—Dated November 1, 1814, To carry into effect this improvement, Mr. S. places a boiler or caldron, made perfectly water-tight, in a situation below the level of that of the vessel intended to be afterwards filled therefrom with hot water. This boiler or caldron is to be provided with a fire-grate, fixed beneath it, or can be attached to a distinct stove, and a supply of cold water must be conveyed to such boiler from a cistern or other reservoir, for the purpose of being there heated. He elevates the water, (after it is rendered sufficiently hot,) either by application of the natural principle and property which invariably impels water to seek the same level as that of its source or head, or by means of the engine, cour monly denominated a forcingpump. He generally adopts the former mode in preference to the use of the forcing-pump, because the latter is attended with a greater degree of expense and trouble. In order to raise the fluid by its own unaided action, the cistern or reservoir must be situated higher than the vessel to be filled with heated water; and such reservoir may be supplied by some one or other of the methods now in frcquent use for raising cold water. It may be tiseful to observe, that this convenience is already, in many instances, furnished by the several water-works companies, who supply for their employers cisterns placed on the tops of manufactories and dwelling houses. From the

reservoir so elevated, let a metal or

[May 1, aperture at which to discharge itself. The warm water may therefore be drawn off at any part of the extent of the ascent-pipe below the level of the reservoir, by inserting in that part a common cock. As soon as the boiler is filled with water to be heated, and before the fluid be permitted to rise through the ascent-pipe, the cold-water pipe must be stopped. This may be effected either by a stop.cock placed any where in the pipe in which the cold water descends, or by a common ball-cock. In the latter case a smaller cistern should be attached to the side of the reservoir into which the water should be received in the first instance through the cock before it pass into the descent pipe, and in which the ball of the cock will freely operate. This smaller cistern, or (where it is not used) the reservoir itself, must be open on the top, (as must also the ascending or hot-water pipe,) in order to permit the escape of the steam. When it is not considered practicable or expedient to adopt the incthod of elevating warm-water, last described, the forcing pump should be employed. In this case he connects the boiler, by means of a branch pipe, with what is called the raising pipe of the pump; and by a cock he stops such raising pipe just above the spot at which the branch pipe of the boiler is inserted into it. The boiler is then filled from the reservoir, and heated; and a volume of cold water being by the action of the pump forced into the boiler, the hot water is displaced, and driven to the same height in the ascent pipe to which that engine would have operated without the addition of his apparatus. -no- Messrs.

N Feb. 24, and March 3, a long but interesting paper by Dr. Herschell was read, detailing the result of many years observations on the sidereal and nebulous appearance of the heavens. The Doctor began by relating his observations on the relative magnitudes of the stars, considering titose of the first magnitude to be equal to our sun; determined the magnitudes and changes in the appearance of a great number of fixed stars; gave a history of the alterations which he has noticed in the aspect of the sidereal heavens, during the last thirty years; and described those stars which have increased in magnitude, or brilliancy, have lost or acquired surrounding nebulae, or have had wings, tails, or other peculiarities. He seems inclined to believe, from his observations, that new sidereal bodies are in a constant and progressive state of formation; that nebulous appearances gradually assume a globular character; that the heavens are not infinite, and that stars have a “compressing power.” He considers the origin and progress of sidereal bodies to be nearly in the following order: first, vague and indistinct nebulae, like the milky way; secondly, detached or clustered nebulae, which consolidate into clusters of stars; thirdly, these stars becoming more defi

nite, appear with nebulous appendages

in the different forms of wings, tails, &c.; and lastly, that all are finally concentrated into one clear, bright, and large star. Dr. H. concludes that the progressive discovery of nebulae will be equal to the improvement of our telescopes, and that in proportion as we are possessed of more powerful, space-penetrating instruments, will our knowledge of the sidereal heawens be extended. Many of his latter

observations directed to ascertain the absorption or condensation of nebulo were made on stars which he had before described in his numerous papers in the Phil. Transact.; others were made on those whose places have been determined by foreign astronomers. On March 10, Mr. Seppins, one of the surveyors of the navy, in a letter to the President, described his new system of ship-building; he observed that notwithstanding the rapid progress in all the arts and sciences, no improvement in naval architecture has taken place during many years. In order to make the simple, but great improvement which he has introduced more intelligible, he began by describing the old structure of ships, of their keel and ribs, or timbers placed at right angles, and the bottom and decks composed of parallel planks. According to the new construction, on which three ships have already been built, and four more are building, the timbers are crossed with diagonal girders at angles of 45, so that the whole frame is rendered much stiffer or more inflexible, and all parts of the structure made to bear their due portion of the pressure at the same time. The first advantage of this plan is the prevention of what is called hogging, or having the centre become convex on the upper, and concave on the lower side. Mr. Seppins fills up the space between the timbers with pieces of wood taken from old ships, made in the form of wedges, which are reversed, driven in tight, paid with tar, and made impervious to water, so that should an outer plank start, the vessel will be in no danger of sinking, as in the old system. This method not only adds greatly to the stiffness and strength of the vessel, but also preWents
