Abstract
LONDON. Royal Society, November 20.—Sir Archibald Geikie, K.C.B., president, in the chair.—Dr. D. H. Scptt: Medullosa pusilla. Medullosa is a genus of fossil plants, with structure preserved, from the Carboniferous and Permian. Only one British species has so far been known, Medullosa anglica, from the Lower Coal Measures, the oldest and simplest member of the genus, with three uniform vascular cylinders. Medullosa pusilla from Colne, Lanes., is a closely allied form of remarkably small size and somewhat simplified structure.—Prof. A. F, S. Kent: Neuro-muscular structures in the heart. The paper deals with the relations of the structures at the auriculo-ventricular junction. Nerve fibres and nerve cells, the exact functions of which are open to conjecture, are numerous in the neighbourhood of the junction. The present work shows that these nervous elements are associated with structures which lie in the connective tissue between the auricular muscle and the ventricular muscle.—George Graham and E P. Poulton: The alleged excretion of creatine in carbohydrate starvation.—J. A. Gardner and P. E. Lander: The origin and destiny of cholesterol in the animal organism. Part xi., The cholesterol content of growing chickens under different diets.—W. E. Bullock and W. Cramer: Contributions to the biochemistry of growth—the lipoids of transplantable tumours of the mouse and the rat.
