ANTIMONI OXY-SULPHURETUM. L. Oxy-sulphuret of Antimony. The Golden sulphur of antimony, and Kermes mineral, are much the same. Prepared by mixing --- of triturated sesqui sulphuret of antimony, Oic of solution of potass, and Oij of distilled water, boiling over a slow fire for three hours, constantly stirring it the while, and adding distilled water to keep up the measure. Then strain, and while it is warm add by degrees enough of diluted sulphuric acid to precipitate the powder of the oxy-sulphuret, which is to be washed free from sulphate of potass, and dried with a gentle heat. Decomposition. First, the potassium of the ooxide of potassium in the solution goes over to the sulphur, and sulphuret of potassium is formed with sesqui oxide of antimony and a portion of sesqui sulphuret not decomposed by the potass. Again, the sulphuric acid unites with potass, forming sulphate of potass in solution, the oxide and sulphuret of antimony being precipitated together. At the same time hydrosulphuric acid is formed, and passes off in form of gas by the hydrogen of the water combining with the sulphur of the sulphuret, while the oxyden of the water potass with the potassium, and this potass, with the sulphuric acid, forms sulphate of potass. Adulterated with chalk, sulphur, &c., and coloured with Venetian red. The genuine is of a bright orange colour, wholly vaporizable by heat, wholly soluble in nitrico-hydrochloric acid, and does not effervesce with acids. Medicinally it is alterative, diaphoretic, carthatic, or emetic, according to the dose, which is from gr. j. to gr. v. in obstinate cutaneous eruptions, hooping cough, rheumatism, and gout, given in any vehicle not containing acids or acidulous salts, e. g. conserve of roses; but is seldom employed.
