ial was soon found unsuitable, on account of its brittleness, and consequent liability to be fractured by shot. Iron armor was suggested in the United States in 1812, in France in 1821, and was experimented upon in England in 1827 at the suggestion of General Ford, who proposed to protect fortifications by wrought-iron bars. in and Medhurst, who again urged the project about 1810. Medhurst, in 1810, published an account of a new method of conveying goods and letters by air, and in 1812 extended the idea so as to provide for the transmission of passengers, whom he proposed to transport at the rate of fifty miles per hour. His project consisted of's Hydraulics. It is possible that the Romans extinguished flames in the same manner. See also Sir William Congreve's English patents Nos. 3201, 3606; 1809 and 1812. At-tached′ Column. (Architecture.) One partially imbedded in a wall. An inserted column. At-tach′ment screw. A binding screw. At′tic. An upp
h caliber, and carrying a projectile weighting about 30 pounds, was introduced into the service at the same time. About 1812, Colonel Bomford, U. S. A., introduced a chambered gun called by him the columbiad. These were made thicker at the breechunton patented the stay in the middle of the link. See chain. The chain-cable was introduced into the British navy in 1812. In making chain-cables, the bar of 1, 1 1/2, or 2 inch iron is heated, and the scarf is made by a cutting- machine; aJohn Bernard Logier, a native of Germany, and resident of London, England, who died about 1852. Patented in England about 1812. It consists of the position-frame, to keep the hands from wandering; the finger-guides, two movable brass frames each alled. Co-lum′bi-ad. An improved gun introduced by Colonel Bomford, of the Ordnance Corps, United States army, about 1812. It was made proportionately thicker at the breech and smaller at the muzzle than the guns theretofore in use, and was th
nes of the image fall, and the plate is corroded at those places by a subsequent operation. Dahl′gren gun. Named from the late rear-admiral John A. Dahlgren, of the United States navy. A gun in which the front portion is materially lightened and the metal transferred to the rear, giving the bottle-shape, which caused some surprise on their first appearance in Europe. Colonel Bomford, chief of ordnance of the United States army, commenced making this experiment previous to the war of 1812, and gave the name of Columbiad to the piece. Da′is. A raised platform at the upper end of a room, of a dining-hall, or room of ceremony. On it the dining-table of celebrities was placed. Its present use is for a throne or rostrum. Dale. A spout or trough to carry off water; as a pump-dale. Dam. 1. A bank or structure across the current of a stream. Dams for reservoirs are among the most important of all embankments, as their failure entails such extensive disasters.
competent to see that the system is in working order at all times. The same system of piping used to extinguish fires may also be used to cleanse the rooms, as occasion may require. This system of protection against loss by fire, or rather mode of overcoming fire, by abundant ramifications of water-pipes throughout all the apartments and passages of a house, as well as upon the roof and walls, is thoroughly described in Sir William Congreve's English patents, No. 3201 of 1809, No. 3606 of 1812, and there seems but little to be added to his proposals where jets are by the turning of a plug caused to issue from center-piece, cornice, skirting-board, cave, comb, gable, and everywhere else. As this was before the era of water-mains, except in a few situations, the proposed supply was brought from cisterns on the roof or from pumps, and each floor or gallery had plugs by which the system of pipes of the respective stories were supplied. A large flax-manufactory, to be run by steampo
the bed-stone and stationary, and had a central pivot for the upper one, which had an eye. The upper stone was turned by means of a vertical handle. See grinding-mill. The mill adopted by Napoleon, and used by him in his invasion of Russia in 1812, consisted of two circular cast-iron plates, about 12 inches in diameter, placed in a vertical position. One was fixed, the other rotated by a hand-crank. The plates were indented all over with radiating grooves, and the corn was conducted to th wheels clear of the rails. When the carriage is transferred, the water is allowed to flow back from the pumps to the cistern, and the carriage lowered into place on the rails. See also Figs. J, plate opposite page 1150, and L, page 1157. In 1812, Bramah patented a plan for laying water-mains in cities, the water to be under heavy pressure from force-pumps, and to be used for extinguishing fires and for operating hydraulic machines in factories, warehouses, etc., for elevating heavy weight
n of the femoral artery was first performed by Hunter, about 1785. That of the external iliac by Abernethy, 1796. The internal iliac by Alexander Stevens, in 1812. The common iliac successfully by Dr. Valentine Mott, in 1827. The common carotid by Sir Astley Cooper (successfully), in 1808. The innominata by Mott in arly times the light was a fire of burning wood. Such were the lights of the famous Pharos of Alexandria, and the Tour de Corduan at the mouth of the Garonne. 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 and Middletown, 3 1/2 miles distant, and perhaps was the first successful locomotive in regular use. It drew trains of 30 tons weight 3 3/4 miles per hour. In 1812, Blackett made a series of experiments which proved that the expedient of a pinion and rack-rail was unnecessary; and Chapman patented a A, Blenkinsop's locomo
great antiquity. It was practiced in Egypt at a remote period, and is shown in very successful condition about 1355 B. C. See the chairs, boxes, mummy-cases, and furniture of Rameses III. in the Description of Egypt, by the French savans, about 1812. The book is in the Congressional Library. The art was very popular in India in times of whose dates we can only guess. The Chinese, also, were early in the field, and excelled in this as they did and do in whatever requires patient toil and ful men. Mr. Murdoch will be recollected as the great gas-engineer, and a successful builder of a locomotive in early times. Captain Lean is credited with a general advance which soon afterward took place.

tates. These differed from the columbiad, invented by Colonel Bomford, United States army, about 1812, in being lighter in proportion to their caliber and in having no elevating rack on the cascabel, of wood or stone inclosed in iron frames were in use in England thirty or forty years ago. In 1812, Loudon suggested laying cubic blocks on a foundation of flag-stones, or cast-iron plates on a be, whereas in diffused daylight they did so rapidly, and in sunlight with explosion. Berard, in 1812, made a comprehensive and valuable series of investigations, which was reported on by Berthollet, great hight (6 feet) and length of action were unfavorable to delicacy and ease of touch. About 1812, Mr. Robert Wornum introduced an upright piano-forte, the hight of which was from 4 to 5 feet; th a number of variations, which are considered under atmospheric Railway. Medhurst's plan (1810-12), and the one adopted in the Crystal Palace Railway, Sydenham, England, was to run the car on rail
ck and propel the train. It was at that time supposed that the adhesion of the driving-wheels to the track would not be sufficient under ordinary circumstances to enable the locomotive to draw the train. See locomotive, Fig. 2984. Chapman, in 1812, substituted four pairs of drivers connected by gearing, so as to multiply the frictional contact. Snowden, in 1824, had a hollow trunk between the two rails and depressed below the surface. On one side of this trunk was a rack, and the trunk d small charges of gunpowder. Fire communicated to the upper end ignites the charges successively, which throw out the stars until all are discharged. b. A similar firework in paper tube. Ro′man-cem′ent. A kind of cement originated about 1812, by Parker, of London. The term Roman is a misnomer. Septaria — nodules of indurated clay with lime and iron — are burned, ground, and mixed into a mortar with lime and sand. It hardens very quickly, and is very durable. See pozzuolana; hydra

Evett's reverberatory furnace (English patent, 1812) has a conductor which introduces a body of air through the bridgewa them in their manufactories, making large fortunes by their use. In 1812 the British government awarded him £ 5,000 as a mark of approbation.t features of modern naval warfare: Twin screw, 1805; armor plating, 1812: inclined armor, 1812 and 1841; training guns by rotating the vessel1812 and 1841; training guns by rotating the vessel, 1812 and 1862; engines and screws below water in war-vessels, 1841; large engines to work expansively at ordinary times, and with maximum po1812 and 1862; engines and screws below water in war-vessels, 1841; large engines to work expansively at ordinary times, and with maximum power in action, 1841: concentrated fuel, working to petroleum?) 1841; iron hulls for war-vessels, 1841; wroughtiron rifled gun, 1841; the Armsth the facts. Charles Brown had built for Fulton, between 1806 and 1812, six steamboats of lengths varying from 78 to 175 feet, and tonnage Bell's steamboat, the Comet, was built in Greenock, and plied in 1812 between Glasgow and Greenock.
