    cipitated Sulphuret of Antimony. Take of tersulphuret of antimony, in powder, 3vij, solution of soda Oiv, dis- tilled water C ij. Mix, and boil them over a slow fire for two hours, stirring frequently, and adding more water as it wastes. Filter the solution [through linen] and add gradually diluted sulphuric acid q. s. to throw down the oxysulphuret, [avoiding the poisonous fumes.] Wash the precipitate with water, and dry it with a gentle heat. Dose, as an alterative, j to iij grains; in larger doses, as v to xv grains, emetic. See Antimonii Sulphuretum Aureum, E.; and Ant. Sulphuretum Precipitatum, D. vTimonix Porassio-Tartras. L. Mix Ibj finely pow- dered tersulphuret of antimony with f3xv of sulphuric acid in an iron vessel, and expose them to a gentle heat under a chimney, stirring it now and then with an iron spatula. Then increase the heat until, the flame of the sulphur being extinguished, nothing remains but a whitish pulverulent mass, Wash this, when cold, till it is no longer acid, and dry. Mix accurately 3ix of this salt with 5x of bitartrate of potash, and boil for half an hour in Ov of water. Filter the liquor whilst warm, and. set aside that crystals may form. The liquid being poured off, dry the salt, and evaporate the solution again for more crystals. [It should be soluble in cold water. A solu- tion of 100 grains should yield 49 grains of a reddish pre- cipitate with sulphuretted hydrogen.] D. (Antimonium Tartarizatum.) Oxide of antimony 5 ounces, bitartrate of potash 6 ounces, distilled water Oij. Rub the bitartrate to a fine powder, mix it carefully with the oxide, and q. s. of the water to form a thick paste; set this by for 24 hours, then pour on it the rest of the water, heated to 212°; and having boiled for 20 minutes, with frequent stirring, in a glass or porcelain vessel, filter through calico, returning the liquid which first passes, so as to obtain a clear solution. After 12 hours, decant the solution from the crystals, and boil to 3, when upon cooling an addi- tional product will be obtained. Dry the salt on blotting- paper without heat, and preserve it in a bottle. E. Oxide of antimony, (see Oxydum Antimonii, E,) Ziij, bitartrate of potash Zivi; mix, add fZxxvij of water, boil for an hour, D
