Not illustrated. 1892 edition. Excerpt: ...mass which was spread on glass plates and dried at 1 Hesse (Pharm. Jour., 3, xviii. 71, 437) considers that Howard's platinum salt was hydrated, being in reality the chloroplatinate of an amorphous base isomeric with cocaine. 60, by which means it was obtained in transparent, brittle, hygroscopic lamina which were nearly insoluble in water and alkaline liquids, but dissolved readily in alcohol, ether, chloroform, benzene and petroleum spirit. The solution was alkaline to litmus, but without effect on phenolphthaleiin (Pharm. Jour., 3, xviii. 71, 437). When boiled with alcoholic baryta, or heated in a sealed tube with hydrochloric acid, the amorphous base yields benzoic acid, and another product not yet identified. From a later investigation (ilnd., xix. 867), Hesse concludes that the amorphous bases from true coca consist chiefly of benzoyl compounds of an oily non-volatile base, together with some cocamine; while, on the contrary, those obtained from Truxillo leaves consist essentially of cocamine, and the cinnamyl compounds of the beforementioned oily base; and the cocamine is in each case accompanied by a base containing H2 less than cocamine. A specimen of the amorphous base from coca examined by B. H. Paul (Pharm. Jour., xviii. 784) is described by him as being pale yellow, and of the consistence of thick Canada balsam. It had a faint odour at once suggestive of benzoin and butyric acid, and a distinctly bitter taste, but produced no anaesthetic effect on the tongue until after the lapse of some minutes, and then very slight compared with that produced by cocaine. Hygrijte. Under this name several bases have been described, which were either impure or actually dissimilar. The name was first applied byLossen to a liquid volatile base which has..show more
