ships of the Scythian leader Vitalian, when he besieged Constantinople in the beginning of the sixth century. It must, however, be mentioned that Malaba, another old chronicler, says that Proclus operated on this occasion by burning sulphur showered upon the ships by machines. Stettala, a canon of Milan, made a parabolic reflector with a focus of 45 feet, at which distance it ignited wood. It is understood to be the first of that form, though Digges in the sixteenth century, Newton and Napier in the seventeenth century, experimented with parabolic mirrors. Villette, an optician of Lyons, constructed three mirrors about 1670. One of them, purchased by the King of France, was 30 inches in diameter and 36 inches focus. The diameter of the focus was about 1 inch. It immediately set fire to green wood; it fused silver and copper in a few seconds, and in one minute vitrified brick and flint earth. The Baron von Tchionhausen's mirror, 1687, was a concave metallic plate 5 feet 3

The process of refining silver with lead in a furnace is described by Ezekiel, and is regarded by Napier as substantially coincident with the modern cupellation. Cu′pel-lo.

ppear to dissolve into the other. Mag′is-tery. A fine substance deposited by precipitation. Mag′is-tral. 1. (Metallurgy.) Made from copper pyrites (or raw magistral), which is found in many parts of Mexico. These ores, according to Napier, contain from 7.47 to 13.75 per cent of copper. It is reduced to powder by dry stamping and grinding. It is used especially in the patio process of amalgamation. Some authorities state that the copper pyrites are roasted and ground, but this wbjects to be gained in the modification of the land engines to suit the change of circumstances are,— Compactness, to save room on board and secure protection below decks. A low center of gravity, to increase the stability of the vessel. Napier's side-beam engine is the form which has been extensively adopted in paddle-wheel vessels. and is the one selected for illustration. A modification of this is found in the lever-engine. An endeavor to dispense with the beam has originated <
gas, or carbureting of air, by passing either through naphtha or coal-oil. Na′pier's bones. Instruments invented by Napier for performing some of the fundamental rules of arithmetic by a mechanical process. They may be made of bone, ivory, horand figures being placed in the right-hand triangles, and the tens in the left. Jonas Moore tells me the mighty use of Napier's bones, so that I will have a pair presently. — Pepys's Diary, 1667. They were first described by the inventor, John, Lord Napier of Murcheston, in his Rabdologiae seu Numerationes per virgulas, Libri duo, ed. 1617. A moon dial, with Napier's bones, And several constellation stones. Hudibras. Na′pier's Com′pass. A draftsman's compass, to one leg of nt and pen. These fold in between the legs, so that the instrument may be carried in the pocket without inconvenience. Napier's compass. Nap′ping. (Hat-making.) A sheet of partially felted fur in a stage between the operation of the
he oyster, just as measles are in pork. The oysters of Britain were highly esteemed by the epicures of the Roman Empire. Oys′ter-knife. A strongly stocked and thickbladed knife which is thrust between the shells of the bivalve, being a case of forcible entry. In America, the power of the mollusk is somewhat impaired by hammering upon the hinge, but in England the knife is driven between the shells without previously demoralizing the fortress. Oys′ter-o′pen-er. An invention of Napier, England. The bivalve is laid on a stake and a notch taken out of the edge of the valves by a lever knife. It is then placed edgewise between a pair of knives, which are forced together and separate the shells. Oys′ter-rake. One for raking up oysters from their beds. Usually dragged overboard by a sailboat, and known as a dredge. See oyster-dredge. Oyster-cracker. Oys′ter-shell Crack′er.

A form of marine engine invented by Napier of Glasgow. The original beam-engine was the atmospheric engine ofof compactness of the structure rendered desirable the change which Napier accomplished. The lowering of the center of gravity increases th find the names of Gough, Summers and Ogle, Boase and Rawe, Heaton, Napier, Palmer, Gibbs and Applegath, Church, Redmund, Squire and Macaroni,nd Vivian, 1802, but the plan was adopted into the marine engine by Napier of Glasgow (Fig. 5755). Fig. 5756 is a longitudinal section of Mf pipes in which steam from the cylinder is condensed. Invented by Napier. It generally consists of a large number of brass tubes about 1/teammains and surrounded by the water of the cold-water cistern. Napier's condenser was a casing around the engine-room, around which the s
steam-boiler in which the water is contained in tubes, upon whose outside the flame plays. The term tube, in this connection, is distinguished from flue. The flame traverses in the latter, but impinges on the outside of a tube. See Plate LXI. Napier's tubular boiler. Oliver Evans's boiler had a number of small watertubes, able to bear a great pressure and exposing a relatively large heating surface. Alban's boiler (Fig. 2685, B) was on the same principle, with the additional idea of dld, O.). In tubular marine boilers, the flame and hot gases from the furnaces are led through a great number of small flue-tubes (of iron or brass), completely surrounded by water to the uptake at the bottom of the chimney Fig. 6756 shows Napier's tubular marine boiler. a a is a cylindrical chamber with a dome top, or outer casing of the boiler; and b b is a smaller cylinder with a flat top c, placed within the chamber a, and constituting the fire-box, which the space included between t
