![AOIDUM TARTARIOUM. Tartaric Acid. Tartaric Acid, or dextro-rotatory hydrogen tartrate, CjHcOg, prepared from acid potassium tartrate. In constitu- tion it may be regarded as dioxysuccinic acid, or dihydroxy- succinic acid, CH-OH-COOH CH-OH-COOH. Characters and Tests.—In colourless, monoclinic prisms. It has a strongly acid taste, and is readily soluble in less than its own weight of tvater and in less than three times its weight of alcohol (90 per cent.). Neutralised, it affords the reactions characteristic of tartrates. An aqueous solution rotates the plane of a ray of polarised hght to the right. Each gramme of Tartaric Acid dissolved in water should requke for neutralisation 13'3 cubic centimetres of the volumetric solution of sodium hydroxide. It should yield no characteristic reaction with the tests for copper, arsenium, iron, potassium, sodium, or oxalates, only the slightest reactions with the tests for calcium or sulphates, and no reaction for lead by the test described under ' Acidum Citricum.' On incineration with free access of air, it should not yield more than 0'05 per cent, of ash. Dose.—5 to 20 grains. AOONITI RADIX. Aconite Root. The root of Aconitum Napellus, Linn. [Bcntl. and Trim. Med. PI. vol. i. plate 6], collected in the autumn from plants cultivated in Britain, and dried. Characters.—Aconite Eoot varies usually from two to four inches (five to ten centimetres) in length, and from one- half to three-quarters of an inch (twelve to eighteen milli- metres) in diameter at the upper extremity, gradually tapering below. Dark brown in colour, marked with the scars and bases of broken rootlets and crowned with the remains of an undeveloped bud. Fracture short.
