Abstract
LONDON. Royal Society, April 10.—Sir Alfred Kempe, vicepresident and treasurer, in the chair.—L. Hill and M. Flack: The effect of lability (resilience) of the arterial wall on the blood pressure and pulse curve—Prof. J H. Priestley and R. C. Knight: The nature of the toxic action of the electric discharge upon Bacillus coli communis. (1) Electric discharge in air is fatal to bacteria exposed to its action. (2) The effect is due to the products of the interaction of the constituents of the air, namely nitric and nitrous add and ozone. (3) Discharge in air-free hydrogen has no deleterious effect on the organisms, but the presence of small quantities of air allows the formation of a toxic substance, probably hydrogen peroxide, which again exerts a bactericidal action. (4) It, therefore, follows that electric discharges in which the current density does not exceed 10–5 amperes per square centimetre do not exert any directly toxic action upon micro-organisms, a result which is contrary to the statements made by some previous investigators.—S. B. Schryver: Some investigations on the phenomena of “clot” formations. Part I. The clotting of milk.—Surg-General Sir D. Bruce, Majors D. Harvey and A. E. Hamerton, and Lady Bruce: (i) Morphology of various strains of the trypanosome causing disease in Nyasaland. II., The wild game strain. (2) Morphology of various strains of the trypanosome causing disease in man in Nyasaland. 111., The wild Glossina morsitqns strain. (3) Infectivity of Glossina morsitans Nyasaland.
