    Alkaloids. 570. Coniine Hydrobromate. C8 H15 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. C24 H35 N02. a. Nearly white powder. 572. Emetine. O20 H30 ISr2 05 ? a. Pale brown powder. Note.—When pure, emetine is colourless. For formulas suggested for the alkaloid, see Pharmacographia, p. 335. 573. Menispermine. C18 H12 N02. a. White crystalline powder. 574. Morphine. ' C17 H19 N03. a. White acicular crystals. 575. Morphine Acetate. C17 H19 N03, HC3 H3 02. a. Pale fawn-coloured powder. 576. Morphine Htdrochlorate. C17 H19 N03 H CI. a. White powder. 577. Morphine Iodide. C17 H19 N03 H I. a. Crystalline powder. 578. Moephine Valerianate. C17 H19 N03, HC5 H9 02. a. Pale brown powder. 579. Narcotise. C22 H2S NH7. a. Impure, in prismatic needles. b. 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. C23 H29 NH9. a. Acicular crystals. 581. Papaverine. C21 H21 NH4. a. Yellowish crystalline powder. 582. Pilocarpine Nitrate. C23 H35 N4 04 HN03. a. In tufts of acicular crystals. 583. Pilocarpine Phosphate. C23 H35 N4 04 HP03. a. White crystalline scales. Note.—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. Qcinidine. C20 H24 N2 02. a. White amorphous pieces.
