(C21 H22 N2 02)3 H3 As Og. a. Acicnlar crystals. 605. Strychnine Hydrochlorate. C21 H22 N2 02 H CI. a. Silky crystals. 606. Strychnine Hydriodate. C21 H22 N2 02 H I. a. Acicular crystals. 607. Strychnine Nitrate. C21 H22 £T2 02 HN03. a. Shining acicular crystals 608. Strychnine Sulphate. (C21 H22 N2 02)2 H2 S04. a. Minute cubical crystals. 609. Methyl-Strychnia. C21 H21 (CH3) N2 02. a. Yellowish prismatic crystals. Note.—This alkaloid is stated to be non-poisonous. See P. J. [2], vol. L, p. 561. 610. Thebaine. C19H21N03. (Paramorphia.) a. Crystalline powder. 611. Theine. C8H10N4O2. a. Silky crystals, obtained from tea. b. Ditto, obtained from coffee. c. Ditto, obtained from guarana. 612. Veratrine. CggH^NjOg. a. Amorphous white pieces. AMIDES. 613. Acetamide. N H2 (C2 H3 O). a. White acicular crystals. 614. Oxamide. N2H4(C202). a. White powder. 615. Urea. N2H4(C O). a. Colourless four-sided prisms. Note.—This substance has the same empirical formula as carbamide, from which, however, it differs in its product of oxidation. It is placed here as having the composition of an amide. 616. Asparagin. N H2 (C4 H6 N 04). a. Colourless, rather large crystals. Note.—This body has the constitution of an amide of aspartic acid. For fig. of crystals, see P. J. [1], vol. vi., p. 560.
