purins, creatinine and creatine.MLLE.GERTRUDE P ARISET : The synthetic formation of creatine at the expense of the tissue proteins.MLLE.ANNA RAJZMANN : The comparative biological value of the proteins in various species of animals.The biological value of a protein or of a mixture of pro• teins, calculated by the formula of Martin and Robison in the form given by Terroine, from the results of the experiments described, appears to be the same for all the species considered (rat, rabbit, pig).H. TRIMBACH : The liability of various species of animals to ketonuria and ammonuria.The ketone production, reduced to unit weight, is extremely variable in various species of mammals under the same food regime.For a milk diet, most extensively studied, the ketonuria varied between 1 for the calf to 10 for the rat.Similar variations were shown for ammonuria.A. PoLICARD: The fixed mineral matters of the seminal elements in the course of spermatogenesis.Results of the method of microincineration applied to the testicle of the rat.MICHEL V OLKONSKY : The assimilation of sulphates by the Fungi: euthiotrophy and parathiotrophy.Most species of moulds and yeasts are able to synthesise their organic sulphur compounds starting with the sulphate.The Saprolegniaceoo, however, cannot utilise the sulphate ion as a source of sulphur (parathiotrophy) and form an exceptional group.H. VIOLLE : The bactericidal power of sodium ricinoleate.Sodium ricinoleate possesses a high antiseptic power, greater than that shown by oleates.stearates, palmitates or laurates.But this action is specific towards certain micro-organisms only.Bacilli found in the alimentary canal are not destroyed, but bacilli developed in the pharynx, nasopharynx, the bronchials and in pulmonary tissue show, in vitro, a remarkable sensibility towards this soap.It would appear that solutions of this soap could be used as a reagent in microbial diagnosis.ANDRE SERGENT: A new agent for the natural transmission of recurrent Spanish-African fever : the dog tick, Rhipicephalus sanguineus.J. REENSTIERNA: First results of the treatment• of leprosy by an experimental serum.Description of the mode of preparation of the serum and of its application to two cases of advanced leprosy.The results are promising.
