y, and inclosed between two pieces of soft glass in their melted state. The molten glass is dropped upon the surface of the medallion, and the surface afterwards polished. The white clay seen within the clean and highly refractive glass presents an appearance nearly resembling that of unburnished silver. Crys-tal′lo-en-grav′ing. A mode of ornamenting glass-ware by taking impressions from intaglio, and impressing them on the ware while casting. The die is first sprinkled over with Tripoli powder, then with fine dry plaster and brick-dust, and then with coarse powder of the same two materials; it is placed under a press, and at the same time exposed to the action of water, by which the sandy layers become solidified into a cast. This cast thus obtained is placed in the iron mold in which the glass vessel is to be made, and becomes an integral part of the vessel so produced; but by the application of a little water the cast is separated, and leaves an intaglio impression upon

take a vessel of water, which they shelter from the wind, upon which they place a needle buried in the pith of a reed, and which thus floats upon the water. They then take a (magnes) loadstone as big as the palm of the hand, or even smaller; they hold it near the surface of the water, giving it a rotary motion until the needle turns upon the water; they then withdraw the stone suddenly, when the needle with its two ends points north and south. I saw this with my own eyes on my voyage from Tripoli in Syria to Alexandria in the year 640 [640 of the Hegira, 1240 A. D.]. I heard it said that the captains in the Indian seas substitute for the needle and reed a hollow iron fish, so magnetized that when placed in the water it points to the north with its head and to the south with its tail. The reason that the fish swims, not sinks, is that metallic bodies, even the heaviest, float when hollow and when they displace a quantity of water greater than their own weight. Worthy Arabian; we
The powder generally employed in polishing is Venetian pink, a substance containing a small proportion of oxide of iron mingled with earthy matter. It is used with water, which reduces the friction and prevents the glass from becoming heated. Tripoli, crocus, and putty powders, when used with water, cut too actively to produce a high polish in this way; though they are employed dry for the last finish in hand polishing, the amount of surface acted on with the velocity and power of the machinor like purposes. Silex in its various forms, as quartz, sand, etc., and mixed with alumina and other mineral substances constituting grits or grindstones, hones and slates, pumice-stone, and some others, are used for abrading and polishing. Tripoli and rotten-stone are employed in polishing the surfaces of metals and other substances. The oxide of iron, called crocus and rouge, and the oxides of tin and lead, known as putty-powders, are extensively used in the arts for producing very smo
described circumstantially the preparation of sugar from the juice of the Saccharum officinarum in the province of Khorasan. It is also mentioned by Paul Eginetta, a physician. A. D. 625. The Arabs seem to have introduced it wherever they went, finally into Sicily and Spain. Through them it became known to the Crusaders, who liked the sweet honeyed reeds, and one of their chroniclers describes the mode of expressing and purifying the juice as practiced by the inhabitants of Acre and Tripoli. The cane was cultivated in Cyprus, 1148, and a grant from William II. of Sicily, in 1166, includes a sugar-mill with all its rights, members, and appurtenances. It does not, however, appear to have been generally known in Europe prior to the middle of the thirteenth century. It is said that a Venetian merchant in 1250 visited Bengal and informed himself of the mode of culture and preparation. The art of refining sugar and making sugar loaves was also communicated by a Venetian abo
