[Silliman's Journal, vol. XXX. No. 1. Mechanics' Register. British Projects for 1835.-The following abstract is made from an article in the London Magazine of Popular Science, for February, 1836, where the particulars are given at large: Number of projects relating to steam, ten; amount of capital required, 1,889,000l. Gas, three projects; capital required, 295,000l. Mines, fortyone; capital, 3,006,200 Railways, thirty-seven; capital, 35,424,000l. Miscellaneous, thirty; capital, 9,345,000l. Total capital required, 49,957,2004., or nearly $204,000,000! A few of them are foreign schemes. Desiderata in the Construction of Stage Coaches.-The greatest possible height of all the wheels; greatest possible depression of the body; shortness of perch; length of axletrees; diminution of bearings and tires; length and pliancy of springs. [Parnell on Construction of Coaches. Rev. in Lond. Mag. Pop. Sc. Beet Root Sugar.--At the recent meeting of the German naturalists, at Bonn, the section of agriculture and rural economy was almost entirely occupied with papers and discussions on this subject. At Valenciennes, a manufacturer has succeeded in discovering a method of crystalizing the whole of the saccharine matter of the beet, without producing molasses in the process. [Ibid. Harrison's Chronometers.--It is stated that Harrison, of London, received from the government for his chronometers, at different times, sums amounting to one hundred and ten thousand dollars. [Naut. Mag. Hint to Dyers-A practical dyer of Troyes, in France, asserts that the acetate of iron is much preferable to the sulphate, in dying blacks. That stuffs which are injured by washing in caustic leys, or even soap, may be cleansed by rubbing in a weak starch bath. [Bulletin Soc. d'Encouragement, &c. Hint to Bleachers.-The same individual states that muriatic acid, used instead of sulphuric, in decomposing bleaching salts, does not render woolen goods harsh, as is often the result of the common acid bath. [Ibid. Cast-iron Piano.--The society for encouraging the arts at Rouen, France, have awarded a premium to Messrs. Eder & Gaugain, for a piano, the frame of which is of cast-iron. The strength of this material, in proportion to its bulk, gives it advantages over wood. [Ibid. Experiments on Hydraulic Cements.-The society for the encouragement of national industry in France, have appropriated six hundred francs for experiments on the different hydraulic cements. [Ibid. Preserving Marble by Wax.--It is well known that some of the inferior varieties of marble are acted upon by frost. A Mr. Henning, in London, has preserved several sculptured pieces, by causing them to imbibe was. The stone and wax are both heated. [Lond. Mech. Mag. Steamboat Lexington.--This boat, which ran, during the summer, between New York and Providence, making the passage by daylight, is dis cussed in the London Mechanics' Magazine, under the title of the "Fastest Ship in the World." Greenwich Railway Project. This extraordinary project is to carry a railway upon a viaduct from London to Greenwich, three and three-quarter miles, on a series of between 900 and 1000 arches. This arcade to be a series of shops. Action of Salt Water on Cast-iron.-Sea water so alters the nature of cast-iron, that its cohesion appears to be quite destroyed. Cannon which have been fished up, after lying long in the sea, have been found converted, through their substance, into something resembling plumbago, and admitting of being cut with a knife. [Mining Journal. Naut. Mag. Statue of Brick and Mortar.-A statue of the late king George the Fourth, erected at London, is built of bricks and mortar, coated, we presume, with cement. [Loudon's Arch. Mag. Whalebone Pen-holders.-These holders for metallic pens are highly recommended for flexibility, by a correspondent of the London Mechanics' Magazine. Mineral Pitch Lake of Trinidad.-This extraordinary body of mineral pitch is about half a mile in length, and a sixteenth of a mile in breadth. Numerous pools of water exist on its surface. The mineral is hard enough to bear the weight of a man of common size, unless when heated by the sun. It is unlike vegetable pitch, being allied to coal. It is used by the inhabitants of Trinidad for making roads, and cementing stones under water. Gas has been made from it. [Jameson's Journal, from Webster's Voyage. Canadian Twin Steamboat.--A large steamboat is said to have been constructed at Prescott, Upper Canada, upon a principle similar to that of Mr. Burden, but with improvements. The thing will prove, probably, as little applicable to practice in the improvement, as in the original. Erection of the York Column.-This monument, recently erected at London, to the Duke of York, is a Tuscan column, surmounted by a statue. The weight of the statue is 16,480 lbs., and it was raised to its place, 123 feet from the base of the column, in seven hours. It is said to have been greater in weight than any other statue raised to the same height in Great Britain. List of American Patents which issued in March, 1836. 141.
