Cjiclude that these compounds have a different constitu- 

 te. — A. Boutaric : Cryoscopy in fused sodium thio- 

 sphate. NajSjOa-sHjO melts at 48-5° C. The tempera- 

 tre of equiHbrium between the soHd hydrates with sH^O 

 al 2H2O and the solution is 48-2° C. Various organic 

 ^stances and salts of sodium give a molecular lowering 

 iithis solvent of 44° ; salts of other metals produce about 

 dible this lowering. — A. Besson : The formation of 

 hlrogen peroxide under the silent electric discharge. It 

 improved that H^O^ can be formed by the silent discharge 

 a;ing on moist rarefied air at a moderately low tempera- 

 ::lfe, conditions realised in the upper regions of the atmo- 

 diere. Although ultra-violet light may be one cause of 

 M presence ^of hydrogen peroxide in rain water, these 

 |4)eriments prove that electrical phenomena may also be 

 id contributory cause. — J. Bougrault and C. Char-aux : 

 ifictarinic acid. This acid has been shown in a previous 



Pr to be a ketostearic acid. The application of the 

 :mann reaction proves the ketonic group to be in the 

 ;ion 6, the formula being 

 i; CH,— (CH,),^— CO— (CH,)„— CO3H. 



!^. B. Senderens and J. Aboulenc : The catalytic 

 Verification of the dibasic acids in the wet way. Quanti- 

 pive studies of the formation of esters of malonic, 

 cinic, oxalic, and phthalic acids in presence of small 

 iantities of sulphuric acid, aluminium sulphate, or 

 assium bisulphate as catalysts. — k. Roussy : The life 

 fungi in the fatty acids. It is shown that moulds which 

 w well in a medium containing a certain quantity of 

 owe their development rather to the fatty acids than to 

 glycerol. It is only in rare cases, in particular for 

 pefgillus and Penicillium, that glycerol is as good a 

 'ium as the fatty acids. — Raoul Combes : Researches 

 the formation of the anthocyanic pigments. — J. 

 limont : A new method for the physical analysis of soil. 

 -T.ouis Gaucher : The digestion of casein. Milk is only 

 lated in the stomach, and the clots reduced to a fine 

 ■ if division by the contractions of this organ. The 

 iptonisation occurs in the intestine, and may even be 

 mtinued in the duodenum. The coagulation of the milk 

 i thf" stomach is not a necessary condition of its digestion. 

 V . Houssay and A. Magrnan : The wing surface, the 

 ii^Iit of the pectoral muscles, and the feeding process in 

 I t.iin birds. — A. Desgrez : The influence of the chemical 

 'Msiirution on the toxicity of nitriles and amides. Un- 

 ited nitriles are more toxic than saturated nitriles 

 iiing the same number of carbon atoms. ^E. 

 'isonet : New considerations on the disease of bitterness 

 nos in its relations with the acrylic fermentation of 

 'il. The acrylic fermentation of glycerol is at least 

 f the essential processes undergone by wine when it 

 ps bitterness. — A. Daniel-Brunet and C. Rolland : 

 ■hution to the chemical and physiological study of 

 'patic gland in cattle. — P. Mazd : Experimental 

 -is in maize. — Raphael Dubois : Microbioids. — M. 

 urnier : The existence of coal at Franche-Comt^, at 

 Germain near Lure (Haute-Safine). Details are 

 of the strata found in three trial borings ; the coal 

 is similar to the Ronchamp coals. — L. Cayeux : 

 xistence of organic remains in the ferruginous rocks 

 iif>d with the Huronian iron minerals in the United
