605. STRYCHNINE HYDROCHLORATE. C 21 H 22 N 2 2 H Cl. 



a. Silky crystals. 



606. STRYCHNINE HYDRIODATE. C 21 H 22 N 2 2 H I. 



a. Acicular crystals. 



607. STRYCHNINE NITRATE. C 21 H^ N" 2 2 HN0 3 . 



a. Shining acicular crystals 



608. STRYCHNINE SULPHATE. (C 21 H 22 N 2 2 ) 2 H 2 S0 4 . 



a. Minute cubical crystals. 



609. METHYL-STRYCHNIA. C 21 H 21 (CH 3 ) N 2 2 . 



a. Yellowish prismatic crystals. 



Note. This alkaloid is stated to be non-poisonous. See P.-J. [2], 

 vol. i., p. 561. 



610. THEBAINE. C^H^NOg. (ParamorpUa.') 



a. Crystalline powder. 



611. THEINE. C 8 H 10 N 4 2 . 



a. Silky crystals, obtained from tea. 



b. Ditto, obtained from coffee. 



c. Ditto, obtained from guarana. 



612. VERATRINE. C 32 H 52 N" 2 O 8 . 



a. Amorphous white pieces. 



AMIDES. 



613. ACETAMIDE. N H 2 (C 2 H 3 0) . 



a. White acicular crystals. 



614. OXAMIDE. N 8 H 4 (C S O 3 )*. 



a. White powder. 



615. UREA. N 2 H 4 (CO)". 



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 H 2 (C 4 H 6 N O 4 ). 



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. 5GO.
