    AURI ET SODII CHLORIDUM—BALSAMUM PERUVIANUM. of arnica is spoken of in America, the tincture of the flowers is always intended; in Great Britain, the tincture of the root is meant. An Extract of Arnica Root (of un- certain strength) and a Fluid Extract of Arnica Root (of which one cubic cm. represents one gram of arnica root) are also official. (U. S. P.) General Surgery.—The tincture of arnica is a popular application for relief of Sprains, Bruises and External Inflammations; yet violent erysipelatous inflammation has been known to follow its use. This is likely to occur if the application is covered with an impermeable dressing, which prevents evaporation. It is said that the infusion or decoction of arnica is not so liable to produce local irritation as is the tincture. Notwithstanding its popular reputation, there is nothing to show that arnica is superior, as a local application, to laudanum and water, lead water, and other sedative lotions. Diseases of the Mouth.—Arnica is described by Leffmann'(''Ameri- can System of Dentistry, iii, 695) as a stimulant in inflammation of the mucous lining of the mouth. Equal parts of tincture of arnica and glycerin diluted with water is employed by dentists. AURI ET SODII CHLORIDUM. Chloride of Gold and Sodium. A mixture composed of equal parts of dry chloride of gold and chloride of sodium. (U. S P.) It is of a golden yellow color, and, when crystallized, is in long prismatic crystals, unalterable by exposure in the air. (U. S. D.) It is soluble in water. It should be protected from light. The chloride of gold can be dissolved out of the double salt by alcohol. Chloride of gold is antiseptic and escharotic. It bears a resemblance in therapy to the bichloride of mercury. Diseases of the Throat, etc.—J. Solis Cohen Diseases of the Throat ) refers to this agent as a substitute *for the nitrate of silver in the treatment of inflammation of the pharynx. It can be used in strengths varying from fifty to sixty grains to the ounce of water. A solution of the chloride of gold is employed in dentistry to overcome the sensitive- ness of dentine. Diseases of the Eye.—Chloride of gold was some years ago strongly recommended as an application in Granular Lids, substituting nitrate of silver, but did not survive the test of clinical trial and soon went out of use. BALSAMUM PERUVIANUM. Balsam of Peru. A balsam obtained from Myroxylon Pereirce. A thick liquid, brownish-black in bulk, reddish-brown and transparent in thin layers, having a syrupy consistence, a somewhat smoky, but agreeable and balsamic odor, and a warm, bitter, afterward acrid taste. It is entirely soluble in five parts of alcohol. (U. S. P.) It is insoluble in
