AN ALKALOID FROM DELPHINIUM BROWNII RYDB.

Delphinium brownii contains a total of 0.5% of alkaloids, hydrolysis of which yields a crystalline base, probably C22H37O7N or C23H39O7N, together with anthranilic and methylsuccinic acids. Mannitol is present in considerable amounts.

II. Notes of researches on the poly-ammonias.—No. II. Action of chloroform upon aniline

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.
