im till the year 1772 that this could be effected by the gases dislodged from decomposing chalk and other calcareous substances confined in an air-tight vessel. Dr. John North's apparatus for impregnating water with carbonic acid was invented in 1775. Between the years 1807 and 1852 thirty-one English patents were granted for apparatus and methods for preparing aerated water, and fifteen patents for vessels to hold such waters, and for methods for bottling. The most common beverage is Carbon which will show the absolute pressure in pounds and fractions to the square foot or inch. The earliest known anemometer was that of Dr. Crombie, 1667, afterwards improved by Wolfius and others. Dr. James Lind of Windsor invented, about the year 1775, a very convenient and accurate anemometer which is well suited for private observers or those desiring a portable instrument occupying a small space. It consists of a graduated glass tube having two arms, one of which has the upper part bent per

ete. Concrete or beton walls. Hollow tile walls. Iron frame with wire-work riveted thereto and covered over with plaster or concrete. See wall, where many varieties are illustrated. The means for fire-proofing the necessary openings, that is, the door and window ways, are by louvers, folding, sliding, swinging, and rolling shutters of iron. Some made double with intervening air-space; others made to close automatically by the increase of heat when exposed to fire. Hartley's patent, 1775, consisted of a plan for sheathing wooden work with thin iron plates. Earl Stanhope's plan was to pack all the interspaces of wood-work with incombustible material; preferably concrete. Of other English plans of late date may be cited, iron joists with concrete filling and upper bed supporting the flooring. See flooring, where several varieties are shown. Another plan is cellular joists of earthenware tubes imbedded in cement. Loudon recommends a floor of cement with imbedded ti

In July, 1790, Thomas Clifford patented in England a machine for making nails from the prepared rod by drawing it between rollers having cavities corresponding to the shape of the nail; and in December of the same year he patented a process for drawing bars or plates to a varying thickness and cutting the nails therefrom by a punch. Machines of this kind were in operation at French's factory, Wineburne, Staffordshire, England, in 1792. Cut-nails were first made in this country. About 1775, Jeremiah Wilkinson of Cumberland, R. I., cut tacks from plates of sheet-metal, and afterward made nails and spikes in a similar manner, forming the heads in a vise. Ezekiel Reed of Bridgewater, Mass., in 1786, invented a machine for cutting nails from the plate, and in 1798 obtained a patent for cutting and heading them at one operation. Benjamin Cochran had also constructed a machine of this kind; and Josiah Person of New York, in 1794, patented a machine for cutting nails from the shee

se are the following: chine, ferret, galloon, love, lustring (lutestring), ribbon velvet, sarsnet, satin, taffety, etc. The ribbon manufacture is largely carried on at Coventry, in England, and at Saint-Etienne, in France. A great number of the improvements in the different branches of the manufacture are due to the Swiss and Germans, among others the bar-loom, brought from Switzerland, in 1756, by M. Flachat, of Saint-Chamond, and the economical processes for fining velvet, introduced in 1775, by Roland de la Platiere. The application to the bar-loom of the Jacquard machine, and of the various improvements derived from it, have resulted in the production of an admirable working instrument, with which a skilled workman is able to make everything, from simple taffetas to elaborate portraits. The ornaments vary considerably in style and arrangement. Sometimes these are purely fanciful compositions,—Byzantine, Indian, Oriental, Chinese; at others, of birds and animals, more or le

eel, draft-chain, and drag-chain, to pull the weeds into the furrow. Called also a double plow (which see). English skim-colter plow. It was invented about 1775, by Mr. Ducket, a farmer of Surry, England. As contrived by him, it was a thin plate of iron, with a sharp edge fixed horizontally to a common colter, and its useo support the claims of the Arkwright patents, — the one for the drawing-rollers, 1769; and the other for the combination of carding, drawing, and roving machines, 1775. The case of Arkwright vs. Nightingale, and others in which he appears as plaintiff, occupy a prominent position in the records of patent-law decisions. The ca57 Bernouilli (French) and Genevois (Swiss) experimented with steamboats, the first using a kind of artificial fin, and the latter the duck's-foot propeller. In 1775 we are informed that M. Perier navigated a small steamboat on the Seine. Marquis de Jouffroy's mode of propelling boats. In 1781 the Marquis Jouffroy constr

Monthly, March, 1874, Vol. XLVII., pages 540-542. Warp-ma-chine′. A lace-making machine having a thread for each needle employed; in contradistinction to the stocking-frame, which has but a single thread. This machine was invented about 1775; it was improved by Dawson in 1784, by the application of the rotary motion and the cam-wheels to move the guide-bars. Warp-machines were the first to produce ornamental patterns on lace, such as spots, bullet-holes, etc. The Jacquard apparatuarn made by the throstle, or water-frame; so called because in the first cotton-mill, which was organized by Arkwright, the motive-power was a water-wheel. Draining-wheel at Laxey. Previous to the time of Arkwright (his patents were 1769 and 1775), all the operations of cotton were done by operatives at their homes. The cotton was hand-carded, spun, and woven by men, women, and children, who took a bunch of work home and returned it when completed, the houses of the cottagers being in clu
