es the familiar instance of the burning of the fleet of Marcellus by Archimedes, another instance is cited by the historian Zonaras, who records that Proclus consumed by a similar apparatus the 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

b-compasses. Bullet-extractor. Bullet-ex-tract′or. A pair of pinchers with projecting claws, adapted to imbed themselves in a bullet so as to draw it from its bed and extract it. When closed, these form a smooth, blunt surface, like a probe, and are opened against the bullet so as to spread apart the vessels which might oppose the retraction. Bul′let-hook. A hook-ended tool for extracting bullets. An iron bullet-hook was disinterred at Pompeii in 1819 by Dr. Savenko, of St. Petersburg. It was in company with a number of other surgical instruments. See probe. Bul′let-la′dle. One for melting lead to run bullets. It is usually a hemispherical ladle with a spout, but in one case the ladle has a hole in the bottom guarded by a spring plug and operated by a trigger on the handle; in another case a part of the ladle is covered, and the lead thus flows out at a guarded opening which keeps back the dross of oxide.

neath the car, near its rear, and operated by a rope at each end, extending to the steersman's seat. The British military authorities assume that a hight of 100 fathoms at a distance of 600 fathoms from an enemy affords an ample field of view. Cameras arranged so as to include the whole horizon, enable the country to be photographed, and telegraph-wires, which can be paid out as fast as the balloon sails, afford communication with the earth or with another balloon. Experiments made at Tours show that at a hight of 1,000 to 1,200 yards the silk envelope of a balloon could be penetrated by bullets, but that the escape of gas was so slow that with a favorable wind the balloon might reach several miles before falling. At 2,700 yards the best shots failed to penetrate the silk; and this elevation is therefore considered the maximum necessary to insure safety. The late Prussian and French war, and especially the siege of Paris, gave rise to the most business-like and systematic u

A hood for covering the eyes of a runaway horse, as a means of stopping him. Koehler's patent has one strap which pulls a hood over the eyes and another which closes the nostrils.

Each concave mirror was separately hinged, and they were brought to bear in combination upon the object in the common focus.

Egypt and among the later Greeks. They were only used, however, by the wealthier classes. Many ornate bedsteads are represented in the tombs at various parts along the river Nile. Among the earlier notices is the iron bedstead of Og, king of Bashan; it was nine cubits long and four broad (Deut. III. 11). This was adapted for a man twelve feet high. The Rabbinical writers have exercised their ingenuity upon Og, and their highest flight concerns a bedstead, the first mention of the article has a crook, so that the knuckles are not grazed against the timber when hewing. The Israelites west of the Jordan had but small advantages of timber, and. were not skillful hewers. They imported axemen and timber. Lebanon had cedar and fir; Bashan had oak. The kings of Syria and Egypt fought for their possession for centuries. Even firewood was scarce in Judea and Samaria. The poor widows gathered a bundle of sticks then as now.

al neighbors by the way in which they mended castiron kettles and pots, which were supposed to be irretrievably ruined. The first notice of it by Europeans appears to have been by Van Braam, in 1794-95, who was attached to the Dutch Embassy at Pekin, and who afterwards settled in the United States. The figure represents the itinerant artist with his portable forge, at work in the street. The front half of the wooden chest is his Fung-Seang, or bellows. Its principle is that of the doubl lens, of 16 inches diameter and weight 21 pounds, was used to concentrate the rays, the focal distance being then 63 inches, the diameter of focus 1/2 inch. This lens was carried to China by an officer in the suite of Lord Macartney, and left at Pekin. The effects of the burning arrangement were as follows: — Weight.Time. Substances.Grains.Seconds.
