    this mixture often during twenty-four hours, and then throws it on the filter. The liquid passes through entirely colourless ; and on treating it again with ammonia, the morphine is precipitated in the form of a white powder. If this base be then dissolved in alcohol, and the solution permitted to evaporate sponta¬ neously, the morphine crystallizes in the form of beautiful regular crystals. These crystals are perfectly white, have a slight opaline transparency, are entirely devoid of odour, and have an extremely bitter taste. They appear in the form of rectangular four-sided prisms. Sertuerner also uses ammonia, instead of magnesia, to decompose the natural meconate. He then forms a sulphate of morphine by add¬ ing sulphuric acid, which he again decom¬ poses by means of ammonia ; and after dis¬ solving the free morphine in boiling alcohol, he obtains it in crystals, as the liquor cools. This latter method is said, however, to form an impure coloured salt, and also not to yield as much morphine as those described above. [Mr. Brande has lately given the following estimate of the relative proportions of the ulti¬ mate elements of morphine :
