ospheric air to be tested; one third the amount of condensation may be ascribed to the removal of oxygen, whose proportions for combining with hydrogen to form water are, oxygen 1, hydrogen 2, by bulk. The space between the thumb and the surface of the water in the open leg forms an air-cushion when the gases explode. Dobereiner's is founded upon the power of spongy platinum to cause the combination of oxygen and hydrogen gas. The labors of Bunsen, Regnault, and Reiset, Williamson and Russell, Franklin and Ward, have brought the instrument to the present efficient form. Eu′phroe. A long slat of wood, perforated for the passage of the awning-cords which suspend the ridge of an awning. The euphroe (or uphroe) and its pendent cords from a crow-foot Eu′style. (Architecture.) That style of intercolumniation in which the space between the columns was 2 1/2 times their diameter; so called from being considered the most beautiful style. E-vap′o-rating-cone. A Belg
833-39. The iron steam-vessels Nemesis and Phlegethon were used in the villainous Opium War of 1842. They were not the last vessels built on the Clyde for piratical expeditions. The Ironsides was the first iron sailing vessel of any magnitude employed for sea voyages. The Great Britain, built at Liverpool, was the boldest effort in iron shipbuilding in her time, but was eclipsed by the Leviathan, afterwards renamed the Great Eastern, which was built from the designs of Brunel, by Russell & Co., at Millwall, on the Thames. She was commenced in 1853, and was four years in building. The proportions and capacity are as follows: — Length between perpendicular680 feet. Length on upper deck692 feet. Breadth of the hull83 feet. Breadth, including paddle-boxes118 feet. Depth of the hull60 feet. Weight of iron in the hull16,800,000 pounds. Weight with engines, stores, and complement56,000,000 pounds. Draft, loaded30 feet. Number of iron plates10,000 Number of rivets
itize, and develop the plate where the landscape is taken. Accordingly, a number of preservative and dry-plate processes have been invented. In the first class, the endeavor was to cover the wet collodion with some deliquescent substance, such as nitrate of magnesia, glycerine, etc. Such processes are troublesome and unsatisfactory, and in their turn gave way to dry-plate photography. A great many inventors have devoted much labor to this department of photography. Fothergill, Taupenot, Russell, and Wortley have all produced valuable processes, but the details are too technical and elaborate for introduction here. No dry process gives results fully equal in quality to the work from wet plates, but they offer other advantages which cannot be ignored. As substantially different methods, by which both negatives and positives can be made, the collodio-bromide process by B. J. Sayce, September, 1864, and the collodio-chloride process by G Wharton Simpson, about the same time, deser

ious lengths and sizes, for which the old barrels would have been unsuited had they not already been exhausted. Under Russell's patent, 1824 (English), the tubes were first bent up by hand-hammers and swages, to bring the edges near together, andlers, 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 intd seam of the tube being sufficiently open to allow it to pass the fin by which the stem of the mandrel was carried. Russell, 1836 (h i j k o). The end of the skelp being turned around, so as to make the edges lap, it is pulled at a welding heaten at the inner, and lastly in the middle. Drawing between dies restored the circular form and loosened the mandrel. Russell, 1845. The edges of the skelp are lapped on a long bar, which is then drawn beneath a grooved roller, to close the weld
