gine was working with highly compressed air. Mr. Stirling was stated, by the same authority, to have been the originator (1816) of the regenerator wherein the heat of the exhausting air is made to heat surfaces which communicate heat to the incominggiven normal volume, into the space where its expansive powers are to be exerted. The regenerator was used by Stirling, 1816, and Glazebrook, 1797, in air-engines. The forms of the regenerators, however, differ considerably. Stirling's is descri The object of this instrument is to ascertain the value of the alkalies of commerce. It was invented by Dr. Ure, about 1816, or by Mr. Descroizelles, and consists essentially of a graduated tube closed at one end, each graduation corresponding tobs thrown promiscuously together in one heap, they may be taken promiscuously from the heap and will all come right. In 1816, 100 of these arms were made; 2,000, in 1827. In 1836 Congress voted $10,000 to Hall, being at the rate of one dollar per

It is seen in the improved Penrhyn rail, 1805; also in Stephenson and Losh's Patent, 1816. Bel′ly-roll. （Agriculture.) A roller with a protuberant midlength, to roll the sloping sides of adjacent lands or ridges. Belt. 1. (Machinery.)

The amount actually supplied was about 135,000 blocks per annum from 1808 to 1816. 1,500 blocks are required in rigging a ship of the line, besides dead-eyes, say 160.

ar-wheels were made with flanges, to run on the edge-rail, which was first made of castiron and used at Lough borough, England. In Stephenson and Losh's patent, 1816, car-wheels were made with wrought-iron spokes, the hub and rim being cast on to them. A wrought-iron tire was shrunk on to the rim, and secured in its seat by a er power. In 1814 he introduced a new era in the business by commencing on the Naugatuck River the manufacture of the shelf or mantel clock, which he patented in 1816. The cheapness of these created a wide demand. Several improvements made by him in the mechanism, and the later progress in machinery generally, have increased ttradistinction to one forged from a nail-rod, as a clasp, horse-shoe, or flat-head nail. Mr. Odion, of Massachusetts, invented a machine for making cut-nails in 1816. Mr. Reed, of the same State, followed with another machine for the same purpose. Walter Hunt's double-reciprocating nail-machine was introduced in 1841. See n

pushing the disk before it by crowding between it and the conical head, and causing the outer end of the arm to communicate a rotary motion to a wheel f, to which it is connected by a universal joint. Disk-tel′e-graph. One in which the letters and figures are arranged around a circular plate and are brought consecutively to an opening, or otherwise specifically indicated. Disk-telegraph. The first of this class of telegraphic apparatus seems to have been that of Ronald, England, 1816. At each end of the line he had clocks beating in exact unison; at least, such was the requirement of the invention. Each clock-work rotated a disk having the letters and numerals on a circular track, and these were exposed in consecutive order at an opening in the dial, the two ends of the line showing the same letter coincidently. The sender of a message watched till the required letter came in view, then made an electric connection which diverged a pair of pith balls and drew attention

mond by the peculiar movements of the pith-balls according to an agreed code; and Reusser, in 1794, proposed the employment of letters formed by spaces cut out of parallel strips of tin-foil pasted on sheets of glass, which would appear luminous on the passage of the electric spark. In 1795, Cavallo proposed to transmit letters and numbers by a combination of sparks and pauses. Don Silva, in Spain, appears to have previously suggested a similar process. See electrical apparatus. In 1816, Mr. Ronalds experimented with a frictional electricity telegraph at Hammersmith. The current had to pass through eight miles of wire, and the signals were made by means of light pith-balls. The reading was effected by dials at each station having a synchronous movement derived from clockwork. Upon their circumferences the letters of the alphabet were engraved, and a screen with a hole cut through it was arranged at each end of the line, so that only one letter should be visible at a time.

ondon generally, 1815. Streets of Paris, the same year. James McMurtrie proposed to light streets of Philadelphia, 1815. Baltimore commenced the use of gas, 1816. Boston, 1822. New York City, 1825. The Newton gas-well, six miles from Titusville, Pa., discharges at the rate of three millions of cubic feet of gas everyside, near the entrance of which was a supplementary fire which consumed the smoke of the first. Cutler patented a smoke-consuming contrivance for open fires in 1816, and in 1817 Deakin attached a metallic box, holding fuel for one day's consumption, to the back of the fireplace; the fuel was drawn forward horizontally by a scro be placed in a magazine at the breech of the gun and fired by a pin. Various modifications were devised prior to the introduction of the common copper cap, about 1816. This, however, made its way rather slowly. It was not until 1842 that the percussion lock and cap were adopted in the United States military service. The ada

nt, and the ladies sit from morning till night under rich draperies spread over the wooden cover. The palace of the Khalif of Cordova, A. D. 1000, was heated by hypocausts in the vaults below, the warm and perfumed air being conducted by earthen pipes or caliducts in the walls, and discharged into the apartments. Heating by a circulation of hot water, proceeding from a boiler and returning thereto in a comparatively cool condition, was invented by Bonnemain in 1777. (See Incurator.) In 1816 a conservatory at Brompton, England, was thus warmed. See calorifere; hot-water heating-apparatus. James Watt, in 1784, heated his study by a steam box or heater made of sheet-iron, the plates 2 1/2 by 3 1/2 feet and 1 inch apart. This box had an air-escape cock, a steam-induction pipe, and a water-escape. It was supplied by the boiler of the establishment. The experiment was repeated by a system of copper pipes, under Hoyle's patent, 1791. The steam ascended to the top of the bui

In 1812, the Lizard Point light, Cornwall, England, was maintained with coal fires. The same may be said of the Isle of May light, Frith of Forth, Scotland, in 1816. This, in fact, was the usual light at that time in positions readily accessible. The Eddystone light first consisted of tallow candles stuck in a hoop, and afmong other devices, a revolving curtain for closing the keyhole. A detector which indicated if any of the tumblers had been overlifted was patented by Ruxton in 1816. In the same year, Kemp devised a lock whose sliders were operated by a set of small concentric tubes in the barrel of the key. Paper secured over the keyhol

ng volatile products pass through the fire to the chimney. Cutler's magazine-grate was patented in England in 1815. The bottom plate of the chamber was movable, and by means of a wheel and axle the fuel contained in the chamber was raised so as to bring a new portion of fuel into the fire. The object is a full supply for a day, and a means of introducing below so as to burn the smoke. Arnott's improvement, which he termed a smokeless fireplace, is somewhat similar. Deakin's patent, 1816, had the magazine at the back of the fire, and the fuel was drawn forward horizontally by means of a screw. Alkin's English patent, 1825, resembled Deakin's. Rawe's magazine, 1854, is a fuel-pipe connecting the bottom of the grate with a side reservoir of fuel. The poker is the lever for introducing a fresh supply. Leighton, in 1856, surrounded the sides and back of the chamber with a fuel-reservoir, from which the fuel was withdrawn by the poker. See Magazinestove. 4. (Fi

A chair for railway rails was patented by Loch and Stephenson in 1816. The rail to which it was first adapted was a fishbellied rail, whose ends wereo be turned at any angle to reflect the heat of the fireplace into the room. In 1816, the fire-grate was inclosed in a hollow metallic globe opening in front of the airengine of Glazebrook, English patent, 1797, and in Stirling's English patent, 1816. The latter had the metallic sieves of wire gauze afterward adopted by Ericsson<
