    45° Sulphocarbolate of zinc is used'by some French physicians as an astrin- gent for the nasal mucous membrane. {/our?i. de Med. de Paris, 1890.) ZiNCi SuLPHiDUM. Sulphide of Zinc. Sulphuret of Zinc. This compound is found in nature as zinc blende, or it may be prepared as a whitish powder by precipitating acetate of zinc by sulphuretted hydrogen. This method furnishes an impalpable powder adapted to medical use. Diseases of the Skin.—The sulphide of zinc was recommended some years ago by Duhring (^Philadelphia Med. News, November 10, 1883) as a remedy in some forms of Lupus Erythematosus. It is one of the best local appHcations we possess for the sub-acute forms of this affection. The formula employed is the following: B. Zinci sulphat., potassii sulphidi, aa ^ss ; aquae rosse, f giij; alcoholis, f^iij-vj. M. A double decomposition takes place, and the sulphide of zinc is the result. This preparation should not be used in the acute exacerbations which occur in lupus erythematosus, when purely sedative remedies alone should be employed. When, however, the disease is in a quiescent and not highly inflammatory condition—in the sub-acute stage of its progress, in fact—this preparation is useful. ZiNCi Tannas. Tannate of Zinc. When a solution of acetate of zinc is treated with a solution of tannic acid a white precipitate of tannate of zinc is formed. When this is collected, washed, and carefully dried, it furnishes a fine, nearly white powder, insoluble in water, in alcohol, and in ether. Diseases of the Nose, etc.—Tannate of zinc is used by some French physicians as an astringent for the nasal mucous membrane, {/otirn. de Med. de Paris, 1890.)
