On poisons in relation to medical jurisprudence and medicine . Crystals of pure atropia, magnified70 Imperfect crystals of sulphate ofatropia, magnified 30 diameters. of atropia, as it is deposited from an alcoholic solution. Ammoniaadded to the solution of sulphate of atropia does not separate the alka-loid in distinct crystals. In this respect it differs from morphia andstrychnia. When atropia is heated on platinum it melts, darkens incolor, and burns with a yellowish smoky flame. Sulphuric and hydro-chloric acids dissolve it without coloring it. Nitric and iodic acidsproduce with it an ochreous color. Sulphomolybdic acid produces nochange. Tannic acid precipitates the alkaloid from its solutions; butthe most effectual precipitant is the chloriodide of potassium and mer-cury, which throws down a dense white precipitate even in very dilutedsolutions. Atropia is also precipitated by chloride of gold, but unlikestrychnia, it is not precipitated by sulphocyanide of potassium or chro-mate of potash. According to Winckler, atropia is most completely 734 ATEOPIA IN ORGANIC LIQUIDS. precip
