When this precipitate is well dried, he treats it by weak alcohol tor some time, at a temperature less than that of ebulli¬ tion. By this means he separates very little morphine and much colouring matter. He filtrates and washes the precipitate by means of a little cold alcohol : then strongly boils it in a large quantity of rectified alcohol ; fil¬ trates again whilst the liquor still boils, and he finds that the morphine separates as the liquor cools. The colouring matter is got rid of by repeated crystallization.8 a filter, washing it with cold water until the water passes off clear. After which, treat it alternately with hot and cold alcohol Beaurae, (or s. g. 923), as long as the menstruum takes up any colouring matter. The resi¬ due is then to be treated with boiling alcohol of 22-32^ Beaumé, (or s. g. .868), for a few minutes. The solution, on cooling, will deposit crystals of morphia.”—Tr. f Mr. Thomson says 184 grains to the lb. of opium, which is probably a mistake ; because, although he quotes from M. Robiquet’s paper in the Annales de Chimie, his words are, “ boil, &c., with a small quantity (184 grains to lib. 1. of opium) of magnesia.” 184 grains is not a small quantity.—Tr. £ Mr. Thomson obtained a from good Turkey opium](https://iiif.wellcomecollection.org/image/b30796568_0024.jp2/full/800%2C/0/default.jpg)
