A rail whose edges are bulbous and counterparts, so that when one is worn the other may be placed uppermost.

ay consist of a tongue whose end pushes against and puckers up the material in advance of the action of the needle. In the example, Fig. 2202, the device is attached to the presser foot. The upper and lower pieces of cloth are separated by a metallic tongue, so that the feed-bar acts first upon the lower piece and gathers the same. The two pieces of cloth are then forwarded together beneath the presser. There are numerous varieties. See Gregory's Sewing-machine attachments, Washington, 1872. The ruffler acts upon the same principle. Gath′er-ing. 1. (Bookbinding.) The selection and arranging of a set of sheets according to signatures, to form a book. See gather. 2. (Carpentry.)

Ellershausen process consists in the conversion of crude cast-iron into wrought-iron by the admixture of granulated iron ore, a layer of molten iron, and a sprinkling of powdered ore, alternating in molds. These blooms are put in a reverberatory, puddled, squeezed, and rolled. Bessemer has patented in England a mode of applying to the decarbonization of iron, nitrates, chlorates, and other salts, which evolve oxygen when heated. By Blair's process, patents Nos. 126, 923, 924, 925, of 1872, the oxides of iron are subjected, in contact with solid carbon for a certain time, to a uniform red heat, the access of other oxygen during the process being prevented. By this means the oxygen leaves the iron and unites with the carbon, passing off in a gaseous state, while the iron remains, being reduced to a metallic state as iron sponge. The metallic iron thus obtained is, however, in a very sensitive condition while hot, and in that state absorbs oxygen with great avidity; but, if coo

it is conveyed by an intermediate cylinder provided with grippers to the fly at the end of the press, and there deposited, face up, on the pile of printed work. This press, though by no means identical with European machines of the same class, may be regarded as furnishing an illustration of the essential features of them all. The introduction of the lithographic power-press has totally remodeled the lithographic trade throughout the world within the short period of four years (from 1868-72), increasing the possible production about tenfold. It has lowered the cost of, and, in fact, rendered possible, large editions from stone, which, in former times, found their way to the typepress with very inferior results. By this change the general public have profited largely. Litho-graph′ic Roll′er. （Lithography.)

A stream of water is constantly poured through an aperture in the tray, which is arranged to descend as the volume of the mass diminishes by attrition, so as to exert a constant gentle pressure. The marbles are polished between two wooden trays similarly arranged. Clay marbles are molded and baked. Mar′ble, Ar-ti-fi′cial. An indurated composition of gypsum, alum, isinglass, and coloring materials incorporated into a paste and molded into form. In Mellen's patent, 1872, any of the hydraulic or marble cements may be used. The cement is mixed with the colors, each color separately to a consistence which will admit of its being poured from a vessel having a spout. The mixture is poured from the vessels in small streams upon a smooth surface of glass, wood, metal, or plaster of paris, so as to imitate the reins in any particular kind of marble, the interspaces being filled in with a mixture of cement and color corresponding to the color of the body of the s

d these bands, but as they had not succeeded in ascertaining the number of lines in each individual band their claims were not universaily accepted. On the receipt of the Museum photographs, Nobert for the first time acknowledged that the highest four bands had been resolved, and promised that he would endeavor to rule still finer lines. The new twenty-band plate was the result of his subsequent efforts. One of these plates was furnished by him to President Barnard of Columbia College in 1872, and in the spring of 1873 another was received at the Army Medical Museum. Systematic endeavors with the best modern objectives have failed as yet to resolve any of the bands of this plate beyond the tenth, and hence perhaps some will be disposed to deny that they have actually been ruled as stated, but it must be remembered that similar doubts were raised with regard to the finer bands of the nineteen-band plate before they were resolved; and the appearances presented by the new bands are
