. It is of importance to guard against the preponderance of animal life, for an excess of animals over plants in a given space will disturb the balance and lead to their destruction. The demonstration of these conditions is due to R. Warrington, 1850. In some cases where the supply is continuous, the fresh water maintains a healthy condition; and the same effect has been attained by a succession of bubbles of air introduced into and ascending through the water to maintain the natural equilibrrature. The springs which supply the King's Bath, at Bath, England, have a temperature of 117°, and the spring of Orense, in Gallicia, has a temperature of 180° Fah. The artesian Brine-well of Kissingen, in Bavaria, was begun in 1832, and in 1850 water was reached at 1,878 feet. The depth reached by farther boring was about 2,000 feet. The water has a temperature of 66° Fah., and issues at the rate of 100 cubic feet per minute. The ejecting force is supposed to be derived from a subterran

Peel. Hargreaves fixed one of the cards in a block of wood, and the other was slung from hooks fixed in a beam. The hooks remained in the kitchen at Peel fold in 1850, but the cards were destroyed by a mob who came from Blackburn, — a part of the same wretched story of ignorant men opposing the introduction of machinery. The e art, spoke of the possibility of making fac-similes of oil-paintings. Storch and Kramer, of Berlin, successfully reproduced oilpaintings by this process (1840 – 1850). In making chromo-lithographs, an outline drawing is made by tracing, and this is transferred to all the stones (one for each color), required to complete the ation20,000, 000 Power-looms250, 000 Factories2,000 Hands employed inside the walls350,000 Horse-power (steam and water).80,000 Production of cotton goods in 1850 per day4,000,000 yards.

Bishop's floating-derrick was used in 1850 in raising sunken vessels, and consists of a flat-bottomed vessel, 270 feet long and 90 feet beam. It was built by the Th Runjeet Sing.

nvas, and to be propelled by a steamengine in the car working two vertical fan-wheels with oblique vanes; while a frame like the tail of a bird was to act as a rudder, and make the apparatus ascend or descend at pleasure. It did not ascend. In 1850, a Mr. Bell ascended from Kennington, England, in an aerial machine in the form of a prolate spheroid, which, it is said, he propelled by a screw, and steered by means of an apparatus for that purpose, during a flight of nearly thirty miles. If thlled with gas. A similar machine on a large scale had been tried in England some twenty years before, and failed, though a model of it had been to a certain degree successful. Mr. Petin, a countryman of Julien's, projected at the same time (1850) a system of aerial navigation. Certainly a high-sounding name; but then the machine itself was to be on a large scale. It was to consist of an immense framework 480 feet long, supported by four balloons, each 90 feet in diameter, was to have fo

The great Russian diamond weighs 193 carats; cost, £ 104,166 13 s. 4 d. in 1772. The Pitt diamond weighed 136 carats; sold to the king of France for £ 125,000, in 1720. The Koh-i-noor was found in 1550. It belonged in turn to Shah Jehan, AurungZebe, Nadir Shah, the Afghans, Runjeet-Singh, and Queen Victoria, 1850. It originally weighed 800 carats, was cut down to 289 carats by an unskilful Italian, and then to 102 1/4 carats to perfect its shape. See diamond. Pliny speaks of adamant as the hardest of all materials, and it may mean the uncut diamond. We do not know that diamond-cutting was practiced, and it is not certain that diamond-dust was employed in gem cutting and engraving, although there are several indications of its use. He says; Diamonds are eagerly sought by lapidaries, who set them
from ordinary guns in being shorter and lighter in proportion to its bore, and used for throwing hollow projectiles with comparatively small charges. A 6-pdr. gun weighs 100 pounds more than a 12-pdr. howitzer. Their charge of powder for a 12-pdr. field howitzer is 3/4 pound of powder; that for a 12-pdr. mountain howitzer is 1/2 pound of powder.

It is about 36 feet in extreme length, 9 1/2 feet f Sir William Congreve was to be attached to a rocket. General Boxer's light-ball was adopted into the British service in 1850. It consists of a mass of sulphur, saltpeter, and red orpiment, inclosed in a hemispherical case of tinned iron, which is warning light. The first light-vessel moored on the coast of Great Britain was that at the Nore in 1734. There were, in 1850, 26 floating lights on the coast of England. Stevenson states that the annual expense of maintaining a floating light, stress, thinking he had met the Evil One. This locomotive was exhibited before the Institution of Mechanical Engineers in 1850, 66 years after its construction.

A mole trails behind the cutter-foot, and by means of a cord, hooks, and crossbar the tiles are drawn in behind the mole. A mole-plow for laying tiles was made about 1850, and exhibited by Foules, the inventor, at the meeting of the Royal Agricultural Society of England of that year. Attached to the mole was a rope, upon which the sections of tile were strung, and the mole as it progressed drew in 300 feet of t
