ConniDinion to the study of Iho physiological r61e 

 of the nervation of leaves. 1 Ik- main function of 

 the nervation of the leaf is tht- nicclianical support 

 of the limb. The transport of w.ilcr is only a minor 

 function. — E. Aubel and R. Wurmser : The formation 

 of glucose at the expense of alanine and of lactic 

 and pyruvic acids. Experiments on dogs proved 

 that 92 per cent, of alanine and lactic acid are 

 transformed by the animal into glucose, but that in 

 the most favourable case only 80 per cent, of the 

 pyruvic acid underwent this transformation. — A. 

 Quidor and Marcel A. H^rubel : The psycho-physiology 

 of the visual phenomena in animals. — H. Barth616my :

 and of Biifo vulgaris after immersion in water or in

 agalaxy and its culture in vitro. Cultures of this 

 organism have been made in tubes, details of the 

 technique followed being given. The activity of the 

 cultures was proved by experiments on sheep and 

 goats. The organism was visible after staining by 

 the slow method of Giemsa, after fixing the colour 

 (May-Griinwald). — MM. Brocq-Rousseau, Forgeot, and
