VI, No. 2, November, 1914 \ THE PHYSIOLOGICAL ACTION OF THlTOlL InD SEEDS OF CROTON ELLIOTIANUS FROM BRITISH EAST AFRICA J. THEODORE CASH and WALTER J. BILLING From the Pharmacological Laboratory, University of Aberdeen Received for publication, July 11, 1914 Some time ago we received from the Imperial Institute seeds of a Euphorbiaceous plant (Croton Elliotianus) together with a sample of their contained oil. The nature of this oil had been under chemical investigation at the Imperial Institute and Professor Duns tan suggested that an examination of its physio- logical action would prove of interest. The seeds in question are derived from a thinly branched tree 10 to 15 meters high, growing in the vicinity of Nairobi, British East Africa, at an al- titude of 1800 to 1900 meters. The dry lamina is 8 cms. in length by 3 broad, the upper surface being of a dull dark brown color whilst the under surface presents a thick scaly covering. The petiole is 4 to 5 cms. in length. The inflorescence, 20 cms. in length, is openly arranged, the individual flowers being 1 cm. long and stalked. Capsule nearly 3 cms. long by 2.5 broad, oblong, slightly tricarinate, three-seeded. Seeds smooth, ecaruncu- late.^ (After a brief description of the seeds of Croton Elliotianus has been given it is proposed to discuss in this paper their phar- macological action with reference to man and certain of tne lower animals. The action of the oil-free seed and of the oil itself will also be considered.) ‘ Bot. Jahrbiich f. syst. Pflanzengesch. u. Pflanzengeographie. 1904, v. xxxiii, P- 289. C. F. Elliot, Comm. A.
