conduct by detachment of electrons from the atoms of 

 sulphur. — G. Mouret : The prolongation of the fracture 

 of Argentat (Corr^ze) in the region of Dorat (Upper 

 Vienne and Vienne). — L. Dassault : The Tam Dao 

 id the region of the lower river Claire (Tonkin). — 

 Gorceix : The formation of the " Gouf de Cap- 

 reton." A close study of the profile of this cavity 

 iiows that it cannot be regarded as an estuary or 

 \,illey. The best explanation of the observed facts 

 appears to be the assumption of a band of gypsum- 

 salt formation ; the gypsum and the salt have been 

 dissolved by water and the associated clay washed 

 out. — J. Fromaget : The geology of the environs of 

 A Mi Tch^oii (Eastern Yunnan). — M. Gignoux : The 

 presence of the Tortonian at Valence (Spain). — E. 

 Wertheimer : The entero-hepatic circulation of the 

 bile acids. A description of an experiment con- 

 firming the views of Stadelmann on the passage of 

 glycocholic acid in bile of the dog. The eUmination 

 of the bile acids takes place exclusively through the 

 intermediary of the portal vein. — F. Maignon : 

 Researches on the physiological and therapeutic 

 properties of the diastases of the tissues. The 

 existence of synthesising diastases. An account 

 of experiments on the injection and ingestion of 

 diastases extracted from various organs (thyroid, 

 suprarenal capsules, ovary, pancreas, etc.). The 

 action of these diastases is specific, in the sense that 

 those extracted from the Hver exert hepatic functions 

 only, those from the thyroid affect the thyroid 

 secretion, etc. These diastases have no action when 

 administered to healthy subjects whose organs are 

 working normally. — R. Jeannel : The geographical 

 dispersion of Silphidae Catopinae during the Tertiary 

 period. — R. Noel : The phenomena of condensation 

 of fatty bodies on the surface of mitachondria. — 

 R. Argaud : Some functions of the tumoral mega- 

 caryocyle and especially its vasoformative function. — 

 A. Goris and A. Liot : New observations on the 

 culture of the pyocyanic bacillus on definite artificial 

 media. The amides could not be used for the culture 

 of this bacillus ; amino acids could be used, but growth 

 did not take place so readily as with ammoniacal 

 salts of dibasic acids. — T.. Cavel : The method of 

 purification by means of activated sludge and its 

 application to the separative system. — J. Glover : 

 Electrical auscultation of respiration at the com- 

 mencement of tuberculosis. A new method of 

 auscultation based on the use of ampUfying micro- 

 telephonic stethoscopes. — E. SergentandA. Donatien : 

 The stomox as a propagator of trypanosomiasis in 

 dromedaries.
