    silver in an ounce of distilled water; put it into a phial, and add about -V a draclim of pure quicksilver. Tin Tree. Dissolve 3 dr. of chloride of tin in a pint and a half of water, with 10 or 15 drops of nitric acid; and suspend in it a rod of zinc. Turpentine, Venice (factitious). It is usually made by dissolving black resin in oil of turpentine. Dr. Pereira states the proportion to be 5 fluid oz. of the oil to 16 oz. • of resin; but some makers put as much as 8, 10, or even 12 oz. of oil of turpentine to each pound of resiu. [We have introduced this factitious preparation, because no genuine Venice (or larch) turpentine is now to be obtained.] , Turpentine, Oil of. Common turpentine, chiefly Ame- rican, is distilled with water; the oil comes over with the water, and is found floating on it. It is rectified by dis- tilling it again with water. See Camphine and Solvents for India Rubber, for further modifications of this oil. Urn Powder. Oxide of iron, crocus, or jewellers’ rouge. Varnishes. These constitute a distinct branch of manu- facture, and many of them can be advantageously or safely made only on the large scale on premises adapted for the purpose. A few of the most easily prepared and useful varnishes have been selected for insertion. For fuller information see Dr. Ure’S ‘Dictionary of Arts,’ Dumas’ ‘ Cliimie appliquee aux Arts, &c.’ Some practical information on this subject will be found in Mr. Red- wood's edition of Gray’s * Supplement,’ and in the 49th * ,voh of the * Transactions of the Society of Arts.’ Spirit Varnishes. The spirit employed should not be less than 60° overproof. In preparing and using them, they should be kept at a distance from a candle or other flame. Respecting the gums (resins) employed, it may be useful to mention that shell-lac is rendered more soluble by being powdered and exposed for a long time to the air; sandarach gives hardness to varnishes; mastic gives a gloss to a solution of other gums; benzoin still more, but its colour is objectionable; anime readily dissolves, but renders the varnish long in drying; copal and amber are scarcely soluble in spirit, but arc rendered partially so by other gums, and also by being previously fused by
