In a former Note addressed to the Royal Society (Proceedings, vol. ix. p. 150), I have alluded to some [new alkaloids which are produced by the action of the bromides of triatomic alcohols upon the primary amidogen bases. I have since examined more minutely one of these bodies. At the common temperature, chloroform and aniline may be left in contact for a considerable time without any change becoming perceptible. Even at the temperature of boiling water scarcely any reaction takes place. But on exposing for ten or twelve hours a mixture of about equal volumes of chloroform and aniline in sealed tubes to a temperature of 180° or 190° C., a hard brown crystalline mass is obtained, which consists chiefly of the hydrochlorates of aniline and of a new crystalline base.
