L. _Vinum Tartaritis Antimonii_. E. ADULTERATIONS. The importance of employing this article in a state of great purity, for the preparation of so many active and valuable medicines, is obvious. It ought to be entirely volatilized by a read heat; _Lead_ is discovered by its imparting to the antimony a foliated instead of a bladed texture, and from not being vaporizable; _Arsenic_, by the garlic odour emitted when thrown upon live coals; or by the numerous tests mentioned under the history of that article; _Manganese_ and _Iron_, from not being vaporizable, and from other tests: the most usual adulteration is black oxide of iron, or the scoriæ of that metal, “_Smithy dust_.” ANTIMONII SULPHURETUM PRÆCIPITATUM. L. E. Sulphur Antimoniatum Fuscum. D. _Precipitated Sulphuret of Antimony._ QUALITIES. _Form_, a brilliant orange coloured powder; _Taste_, slightly styptic, but inodorous. CHEMICAL COMPOSITION. Very complicated attractions are exerted during the preparation of this substance; the result of which is an hydro-sulphuret of Oxide of Antimony, with excess of sulphur. SOLUBILITY. It is quite insoluble in water. USES. According to the dose, it is diaphoretic, cathartic, or emetic; it is, however, less certain than many other preparations, and, unless in combination with mercury, for cutaneous affections, is not very often employed. INCOMPATIBLE SUBSTANCES. All acids and acidulous salts increase its emetic properties; when therefore acid is suspected to prevail in the primæ viæ, it should be combined with soap, magnesia, (_Form: 128_,) or aromatic confection; on the contrary, the confection of roses, and vehicles containing acids, should be carefully avoided. FORM OF EXHIBITION. Pills. DOSE, grs. 1 to v. OFFICINAL PREPARATIONS. _Pilulæ Hydrargyri Sub-Muriatis_ (=H=) L. ADULTERATIONS. It is often sophisticated with chalk and other extraneous matter; it ought not to effervesce with acids; it should be entirely vaporizable by heat, and its colour should be that of bright orange. A spurious article is vended, which consists of sulphur and sulphuret of antimony coloured with Venetian red. ANTIMONIUM TARTARIZATUM. L. Tartris Antimonii. E. Tartarum Antimoniatum.
