e which the vessel is steering at that moment. When iron ships were first introduced, great difficulty was experienced in regard to the disturbance of the compass, owing to the vicinity of large bodies of iron. It was also shown by Grantham in 1842, and Scoresby in 1851, that the direction of the ship's head on the stocks, the effect of riveting in that position, the magnetic direction while fitting, each had an influence in determining the magnetic condition of the vessel.

Near one end of the beam a few threads are cut, on which is a wheel graduated to degrees, each of which corresponds to half a grain in weight. The coin is placed on the other e

d an eye at the middle of its length was patented in England in the year 1755, for hand-sewing or embroidering, the patentee describing it as used by holding it with the fingers at the middle of its length, so that it will not require turning. In 1829 it was successfully introduced into an embroidering-machine, which is still in extensive use. As many as one hundred and thirty such needles, worked by pincers on opposite sides of the fabric to be embroidered, are used in a single machine. In 1842 a sewing-machine inventor adopted the same kind of needle, and some others have made sewing-machines with such needles, but no such machines have ever been successful. The accompanying cut shows a number of patented needles, some with eyes near their points, some having means of slipping the thread into the eye without reeving. Needles. Needles are known as sharps, betweens, blunts, according to the relative fineness of their points. The so-called golden-eyed needles are tinted b

ally adopted for sporting purposes. It was not introduced into the United States service until 1842. Caps were invented in England in 1814 by Joshua Shaw. He came to the United States for the purare used in preference at Breslau for making this pine-tree wool, which was extensively used from 1842 for mattresses, coverlets, etc. Five hundred of these coverlets were purchased for the hospital oGrooves around the piston filled with an alloy of zinc, tin, and regulus of antimony. 9,411 of 1842.

r. The screws were 5 and 7 feet in diameter, the lengths 7 1/2 and 8 feet. In 1842, the Rattler was built, to determine the best proportions of the screw, and the pying from the patents returned for that purpose. Greenough's sewing-machine (1842). J. J. Greenough's patent of February 21, 1842, had a similar needle, which ernment vessel, was built in 1838, and fitted with a propeller; the Rattler, in 1842. The Robert F. Stockton propeller.

Switzerland, as early as 1800, water-power hammers, and, subsequently, stamps were employed. In 1842, Berendorf of Paris invented pressing-stamps, which were supplemented by Harvey and Debergue wiand tar. Professor Morse is said to have laid a wire between New York and Governor's Island in 1842. In March, 1845, Brooman, in England, patented the method now universally employed for prepariument of this class ever made was erected by Lord Rosse on his estate at Parsonstown, Ireland, in 1842. The diameter of the speculum is 6 feet, having a reflecting surface of 4,071 square inches, — straight mandrel, smaller than the bore. Cutler, 1841 (g h i k n o p). Russell Whitehouse, 1842 (g l p). The skelp, bent into an oval form, was placed on a small mandrel, which filled it acrossn. This was first proposed by a Piedmontese road-contractor, Joseph Medail of Bardonneche. In 1842, a geological survey was made, resulting in the choice of the line at last actually taken. The w

A machine for quartering locomotive driving-wheels on their axles, that is, boring the wrist-pin holes at 90° distance apart. See Quar-tering-machine, page 1842, Fig. 4067. Wheel-rope. （Nautical.) One connecting the steering-wheel with the tiller. Wheel-screw′ing ma-chine′. A machine for boring the holes and fixing the screws in the rims or fellies of wheels to prevent them from splitting or of wood, has been used as a preventive of decay. The wood is to be first steeped in a solution containing 7 per cent of the phosphate of soda. When dry it is again treated with a solution containing 13 per cent of chloride of barium. Payne, 1842, used sulphate of iron (green copperas). The wood is introduced into a cylindrical vessel, and steam admitted to expel the air; a portion of the sulphate solution is then injected to condense the steam and form a partial vacuum, which is co
