re destroyed by a mob who came from Blackburn, — a part of the same wretched story of ignorant men opposing the introduction of machinery. The same Robert Peel, or his son of the same name and the father of the statesman, employed Hargreaves in 1762 to erect the cylinder cardingmachines in a mill at Blackburn. Though the carding-machine was well and efficiently constructed in the time of Arkwright, it was not till after several attempts by different men, Paul, Hargreaves, and Arkwright, woomy as early as 1484. Gemma Trosius, in 1530, suggested their use at sea for acertaining the longitude. In 1741, the English government offered a reward of £ 20,000 for a correct mode of determining longitude at sea. This was won by Harrison, in 1762, who invented and introduced the compensating pendulum balance, made of two metals. See balance; chronometer. The balance-spring, which confers upon the balance the isochronal qualities of the pendulum, was invented by Hooke, who applied it i
s character. Earthen-ware is found among almost all nations and tribes, though not all have the art of glazing, nor have all the art of baking. Drying is not baking, and it requires a good heat to make a good ringing article. The Egyptians and Etruscans had pottery at a date before the historic period. We know more of the former than of the latter at early periods. The resemblance of the Greek and Etrurian ceramic works is remarkable. Glazing came from China. Wedgwood's patents about 1762. See specific list under pottery and clay. Earth-plate. (Telegraphy.) A plate buried in the earth, or a system of gas or water pipes utilized for the purpose, connected with the terminal or return wire at a station, so as to avail the earth itself as a part of the circuit, instead of using two wires, as was the practice previous to 1837.

water at 212° mixed with a pound of water at 32° gives two pounds of water at 122°, the mean of the two components; if, however, a pound of ice at 32° be mixed with a pound of water at 212°, we have two pounds of water at 51° only, . . . . the difference being equal to that required to raise two pounds of water through a range of 71° . . .. representing the heat required to liquefy one pound of ice. — Balfour Stewart's Treatise on Heat. It was discovered by Black, and was taught by him in 1762. d. Specific heat is the quantity of heat required to raise the temperature of a body of a given weight 1°; the unit of measure being the quantity required to raise the same weight of water to the same temperature. Degrees of heat are noted by the thermometer or the pyrometer (which see). In practice the degree is frequently noted as red heat, cherry-red, white heat, welding heat, and so on. See fusing-point.

St. Cloud, in 1695, by Louis XIV.; at Vincennes, 1740; removed to Sevres, 1786. The Meissen, Saxony, porcelain manufactory was established by Augustus II., Elector of Saxony, in 1710. Botticher invented the hard paste in 1706; the red ware like jasper, in 1711: white porcelain, in 1709; the perfect, white kind, in 1715. He died in 1719. Heroldt introduced gilding and painting in 1720; modeled groups, in 1731; porcelain made in England, at Bow, in 1698. Wedgwood ware was first patented, 1762. Porcelain may be distinguished from the coarser earthenware as a pottery which is fine grained, compact, very hard, and somewhat translucid. The latter quality is derived from its partial vitrification. It has various colors. Porcelain is divided into hard and tender. The former is made in Germany and in Asia, and the latter is held to include the ironstone china and similar ware, so heavily manufactured in England. Kaolin is the principal ingredient, mixed with a peculiar mineral,
event their adhering. A slow fire dissipates the moisture, and the heat is then raised until the flame and ware have the same color. The glaze is then added by pouring 20 or 30 ladlefuls of common salt into the top of the kiln. This is volatilized by heat, becomes attached to the surface of the ware, and is decomposed, the muriatic acid flying off and leaving the soda behind it to form a fine thin glaze on the ware, which resists ordinary acids. The labors of Wedgwood date from about 1762, and the art attained great excellence under his fostering care, ingenuity, and taste. We quote from Aiken: — With a liberal ambition far above the mere love of gain, his ruling object was to carry the art that he practiced to the utmost perfection of which it was capable. For this he spared neither time, nor labor, nor expense; and his splendid success, inciting others to follow in the same track, has secured to his country a most important branch of internal and foreign commerce, an
in England and in this country, such as the British Ordnance Survey and the United States Coast Survey, while in France the repeating circle of Borda has been preferred. The telescope has a motion on a horizontal axis, and has a vertical graduated circle, which has also a horizontal. See under telescope for notice of the first use of telescopes in triangulation or measuring angles. The first survey made by an instrument with a perfect circle is said to be that of Zealand, by Bugge, in 1762-68. Ramsden's theodolite had a circle 3 feet in diameter, and was completed in 1787. It had two telescopes of 36 inches focal length. It was used for a triangulation to connect the observatories of Greenwich and Paris, and also in the English, Irish, and Indian trigonometric surveys. The telescope circle and stand are capable of motion round a vertical axis. The altazimuth may be considered a modification of the transit instrument, and has been called a transit theodolite, being adap
-escapement for watches. The detachedlever escapement may be said to be the product of the labors of Berthoud, LeRoy, Earnshaw, Graham, and Mudge. Harrison, 1735-1762, invented the going fusee and the compensation balance for chronometers, finally obtaining the reward offered by the English Board of Longitude for his improvementallons daily to each person. The first water-works in the United States were planned and constructed by Mr. John Christopher Christensen, at Bethlehem, Pa., in 1762. The machinery consisted of three singleacting force-pumps, of 4-inch caliber and 18-inch stroke, and worked by a triple crank, and geared to the shaft of an undeent was introduced, which sustained the cable at every 3 1/2 inches. William Falconer was the son of a barber, born at Edinburgh, 1730; he published the Shipwreck, 1762. He was appointed purser of Aurora frigate, which sailed from England, September 30, 1769, and after touching at Cape of Good Hope was never heard from. Suppose
