Alkaloids. 



570. CONIINE HTDROBBOMATE. C 8 H 15 NHBr. 



a. Transparent six-sided tabular crystals. 



Note. This specimen was presented by Messrs. Morson & Son. The 

 crystals are neutral, and do not appear to be deliquescent, as is sometimes 

 stated. Some very perfect crystals may be seen in the central case in 

 this museum, in which crystalline forms are illustrated. 



571. DELPHINE. C 24 H 35 N0 2 . 



a. Nearly white powder. 



572. EMETINE. C 20 Hgo N 3 5 ? 



a. Pale brown powder. 



Note. When pure, emetine is colourless. For formulae suggested for 

 the alkaloid, see Pharmacographia, p. 335. 



573. MENISPERMINE. C 18 H 12 N0 3 . 



a. White crystalline powder. 



574. MORPHINE. C 17 H 19 N0 3 . 



a. White acicular crystals. 



575. MORPHINE ACETATE. C 17 H 19 N0 3 , HC 2 H 3 2 . 



a. Pale fawn-coloured powder. 



576. MORPHINE HTDROCHLORATE. C 17 H 19 N0 3 H Cl. 



a. White powder. 



577. MORPHINE IODIDE. C 17 H 19 N0 3 H I. 



a. Crystalline powder. 



578. MORPHINE VALERIANATE. C 17 H 19 N0 3 , HC 5 H 9 2 . 



a. Pale brown powder. 



579. NARCOTINE. C 22 H 23 NH 7 . 



a. Impure, in prismatic needles. 

 &. Pure. 



Note. The basic properties of this substance are very feeble ; although 

 freely soluble in acids, it does not for the most part form crystallizable 

 salts with them and is neutral to test paper. 



580. NARCEINE. C 23 H 29 NH 9 . 



a. Acicular crystals. 



581. PAPAVERINE. C 21 H 21 NH 4 . 



a. Yellowish crystalline powder. 



582. PILOCARPINE NITRATE. C 23 H 35 N 4 4 HN0 3 . 



a. In tufts of acicular crystals. 



583. PILOCARPINE PHOSPHATE. C 23 H 35 N 4 4 HP0 3 . 



a. White crystalline scales. 



jfote. These specimens were presented by Mr. A. W. Gerrard, who 

 was the first to prepare the alkaloid in this country. See Journ. Chem. 

 Soc., Oct. 1876, p. 367. P. J. [3], vol. v., p. 965. 



584. QUINIDINB. COQ H 24 ^2 ^2- 



a. White amorphous pieces.
