The roots also contain some resin and amorphous glucosidic material and a quantity of reducing sugar. No alkaloid was present, nor could any trace of a compound capable of yielding hydrogen cyanide be detected. Physiological tests, in conjunction with the results of the chemical examination, afforded no evidence that the roots of the scarlet runner bean, as obtained from cultivated plants, possess the toxic properties ascribed to them.--Power, Pharm. Jour., 1913, p. 550. Erythrophloeum Guineense.--The bark of Erythrophloeum Guineense (Fam. Leguminosae, sub-fam. Caesalpinaceae), a tree indigenous to central and western Africa. The bark of the tree is also known as sassy bark, casca bark, doom bark, and in the vernacular of the Congo as Nkasa. It has been employed by the natives of western Africa as an ordeal in their trials for witchcraft and sorcery, as well as for other criminal purposes, and apparently also enters into the composition of the arrow-poison of the Pigmies. A chemical examination of the bark resulted in the isolation of several wellknown compounds and the presence of a highly toxic alkaloid, designated by previous investigators as erythrophleine. Neither this alkaloid nor its salts could, however, be obtained in a crystalline state.--Power, Amer. Jour. Pharm., 1912, p. 337. Robinia Pseudo-acacia or common locust (Fam. Leguminosae, sub-fam. Papilionaceae).--The bark of this well-known tree possesses highly poisonous properties. These are due to the presence of a protein, Robin, which is soluble in water.--Power, Amer. Jour. Pharm., 1913, p. 339. Denis Ulignosa (Fam. Leguminosae, sub-fam. Papili...
