ad of quill. The tortoise-shell being softened, points of ruby and diamond were imbedded. Metallic points were also cemented to the shell nibs. Doughty, about 1825, made gold pens with ruby points. See gold pen. Gold pens with rhodium points were introduced soon afterward. Gillott devoted much pains to the improvement ti-friction wheels behind the shares were invented almost simultaneously in England and Scotland, 1813– 15. Wilkie's (Scotch) plow d of this class was invented in 1825. The wheel is journaled to run in the interval between the mold-board and landside, and answers in place of a sole, lessening the friction to a considerable extenabaft the engine and working in the space between the twin boats. Fulton's and Bell's steamboats had side paddle-wheels, as also the Savannah, 1819, Enterprise, 1825, Great Western and Sirius, 1838. The Great Britain, 1843, had a screw, and after this the screw became common. See paddle-wheel. The term propeller is usuall

Easton's English patent, 1825, specifies a central rack, placed between the two rails, and a toothed wheel on the locomotive. emporary connection with the engine of the axles throughout the train. James's English patent, 1825, has a horizontal shaft extended by couplings beneath the carriages the whole length of the trainepers. The Stockton and Darlington Railway, one of the first on which the locomotive was used (1825), has a gage of 4 feet 8 1/2 inches. This was adopted on almost all the British railways, and washe machine. The reel was driven by bevel-gearing. The following machines are American:— 1825. Ten Eyk had a horizontal cylinder, with spiral knives cutting against straight edges. The same was born at Lyons, 1593. See also Ramelli's book, sixteenth century. b is Eve's rotary pump, 1825.

ones being used to produce local insensibility to pain, such as the freezing of the gum in dental operations. One of these light oils, benzol, exhibits in a remarkable degree the number and value of the coal-tar productions. Fifty years ago, in 1825, Faraday discovered, while experimenting on coal-tar, the substance now known as benzol. Twenty years after, a French chemist found that when benzol was treated with nitric acid, a substance called nitro benzol resulted, having the odor of bittero prevent its passing between the rollers, so that the barrel is drawn off the mandrel. This is repeated with progressively smaller mandrels and grooves. Russell, 1824 (b j k l o). The skelp welded by grooved anvil and top tool. Whitehouse, 1825 (g k o). The skelp was turned into position for welding, and was then drawn between dies, or passed between grooved rollers, without mandrel or internal support. Royl, 1831 (c i k o). Two grooved rollers, which received bent and heated skelp, a

The heart is constructed upon the principles of hydraulics, and is furnished with a valve. Harvey deduced the circulation of the blood from Aquapendente's discovery of the valves in the veins. Servetus, who was burnt at Geneva, 1553, was engaged in the search, and came near anticipating the theory which Harvey completed in the following century. See Pulsometer, page 1825; Sphyg-Mometer, page 2265. Fig. 6893 is a caoutchouc pump-valve, which opens to allow water to pass upward as the bucket descends, and closes as the bucket rises. It may have been suggested by the mitral valve of the heart. Perreaux's pump-bucket valve. Valve–buck′et. （Hydraulics.) A bucket provided with a valve; the bucket or sucker of a pump.

on was described and represented in a work written by Mandey and Moxon, and published in London in 1696. Hodgson's wire-tramway, lately introduced into England, is substantially similar to the elevated railways which were patented in England in 1825 by Palmer, Fisher, and Dick. See elevated Railway. An endless wire-rope is carried on a series of grooved pulleys, supported in pairs upon stout posts ordinarily about fifty yards, but in some cases at much farther intervals apart. At one enouth c, and, by the rotation of the cutting-cylinder, are carried around the winding tapering passage c c until they are entirely reduced to fine cuttings. See pulp-grinder, Figs. 4015-4018.

Lee's wood-cutter (English) consists of a massive cast-iron disk, to which a knife is secured, which, revolving at a great speed (200 to 300 revolutions per minute), slices off sections, half an inch thick, from the ends of stout timber balks
