d till 1554. Its use was forbidden by the mufti, but again permitted by an edict of Solyman the Great. The Venetians brought it from the Levant in 1615, and in 1645 it was introduced into Marseilles. Coffee was introduced into England by Daniel Edwards, a Turkey merchant, in 1657. The first coffee-house in England was in St. Michael's Alley, Cornhill, London; opened by Pasqua, a Greek servant of Mr. Edwards. It was then sold at from four to five guineas a pound. Coffee-trees were importeMr. Edwards. It was then sold at from four to five guineas a pound. Coffee-trees were imported from Mocha by the Dutch about 1700, and thence carried to Surinam. In 1714 a coffee-plant was presented by the magistrates of Amsterdam to Louis XIV., and placed in the grounds at Marly. The progeny of this plant were carried to Cayenne and Martinique. In two centuries its use spread all over the civilized world. The coffee-tree does not thrive where the temperature ever sinks below 55° F. It grows to the hight of 12 or 15 feet, has a leaf like the laurel, but not so thick. The blossom

f broken winebottles, etc., are carefully washed to remove dirt, the glass is crushed under a revolving stone and sifted into six sizes, as in manufacturing emery. It is sifted through sieves of wire-cloth, which are generally cylindrical, like the bolts of flour-mills. The cloths have from sixteen to ninety wires to the inch. A surface of thin glue is spread on the paper, and the pulverized glass dusted over it with a sieve. Sometimes two coats of glue and glass are applied. Under Edwards's patent (English), cotton cloth is used instead of paper. Emery, sand, and powdered flint are used instead of glass, and constitute emery, flint, sand paper. Glass-pots. Glass-pot.

ty of the swelling of the gelatine is to a great extent got over; the plate is then inked and printed in the usual way. This is known as Albertype (which see.) Edwards added to the known data, producing a film which is movable. By the adition of alum, more especially chrome alum, to the gelatine, a film can be produced consisting of a tough, tawny, insoluble substance, like leather or parchment, capable of standing an apparently unlimited amount of rough usage. Edwards discovered that gelatine might be converted into this substance, but that it still retained its property of being acted on by light in presence of a bichromate, and of receiving and refnd with it the desirable amount of color. The ordinary rollers are not found to be satisfactory, and a mixture of gelatine, glycerine, and castor-oil is used. Edwards's process is worked in the United States by James R. Osgood & Co., publishers, of Boston, who own the patents. He′LIX. 1. A curve generated by winding a lin
to Poitevin's description of his process, he coated a lithographic stone with a mixture of albumen, gelatine, gum, or similar organic matter (really selecting albumen), and bichromate of potash. He then dried the surface and exposed it under a negative. He then damped the stone, rolled up with lithographic ink, etched, and printed. It may be here remarked that Dixon's experiment contained the gist, though unperceived by any, of the recent important inventions of Tessie du Motay, Albert, Edwards, and others, inasmuch as he really printed from an organic deposit which lay between the ink and the stone. See photo-mechanical printing; carbon-print; gelatine process; Heliotype. 3. Cutting and Bradford, Boston, Mass., patented a process in England, February 23, 1858, and in the United States, March 16, 1858, which consisted in coating a stone with a solution of gum and bichromate of potash, with an addition of sugar; drying the same and exposing under a transparent positive.
