Sulphuretted hydrogen is capable of combining withthe protoxide of Antimony ; and of giving origin to compoundswhich have been long used in medicine ; the first of these hasbeen called Kermes Mineral; the latter Golden Sulphur of An-timony, and is the Antimonii Sulphuretum Eracipilatum of thepresent London Pharmacopoeia. When the powdered nativesulphuret is boiled in a solution of Potass, various composi-tions and decompositions arise, and the solution, on cooling, de-posites an Hydro-sulphuretted oxide of Antimony, which isKermes Mineral. On the addition of a dilute acid to the coldsolution, a precipitate of a brighter colour ensues, and this wthe preparation of the Pharmacopoeia. In my Lectures, Ihave usually endeavoured to impress upon the student thenature of the chemical changes which take place by the fol-lowing diagram. 326 1ARISS MEDICAL CHEMISTRY Sulphuret of Hydro-Sulphuret of Potass. Oxide of Antimony. Sulphuret of Antimony and a Solution of Potass are theagents employed, which, it will be seen, furnish Sulphur,Potass, Hydrogen, Oxygen, and Antimony. During the boil-ing, the potass combines with the sulphur of the sulphuret ofantimony, and forms Sulphuret of Potass ; which, decompo-sing part of the water, attracts its hydrogen and becomesHydro-sulphuret of Potass, while its oxygen converts the an-timony into an oxide, which latter substance is dissolved bythe alkaline hydro-sulphuret. As the solution cools, the af-finities by which these bodies are held together undergo achange, and the oxide of antimony, falling down in combina-tion with sulphuretted hydrogen, constitutes Kermes sulphuric acid is
