NA TURE 



[June 20, 1907 



/3-ketonic compounds : Ch. Moureu and I. Lazennec. — 

 The hydrolysis of sails : A. Rosenstiehl. From a con- 

 sideration of the phenomena of the hydrolysis of esters 

 and salts, the author concludes that the hypothesis of 

 ionisation is unnecessary. — The existence of a tyrosinase 

 in wheaten bran : Gabriel Bertrand and M. Mutter- 

 milch. Wheaten bran is shown to contain at least two 

 ferments, tyrosinase and peroxydiastase. — The basic rocks 

 of the Tschissapa range, northern Ural : L. Duparc and 

 F. Pearce. — The pleural cavity in the elephant : Guillaume 

 Vasse. A fully grown elephant killed in the province of 

 Gorongoza showed on dissection lungs easily detached. 

 There was no point of adherence. — .An improved apparatus 

 permitting of staying and working for a long time in 

 irrespirable atmospheres : J. Tissot. In a previous note 

 the author has detailed the conditions which should be 

 realised in an apparatus of this kind. The present paper 

 gives an account of an apparatus fulfilling these conditions, 

 together with an account of its actual use in practice. — 

 The digestion of chlorophyll and the stomachic excretion 

 in rotifers : P. de Beauchamp. — The hypertensive action 

 of the cortical layer of the supra-renal capsules ; O. Josue 

 and Louis Bloch. The cortical layer has been found to 

 contain substances strongly hypertensive which are 

 chemically different from adrenaline. It Is possible that 

 these substances are destined to form adrenaline later, and 

 researches are being carried on to determine this point. — 

 Radioscopy and radiography applied to the inspection of 

 tuberculous meat : H. Martel. It is shown that the 

 Rontgen rays may serve to detect tuberculous lesions In 

 meat. The cutting into sections necessitated by the 

 ordinary method of examinations is avoided, thus saving 

 time and preventing the depreciation of the meat. Fat 

 does not interfere. — The geosynclinal Miocene of southern 

 Tell (departments of Algiers and Constantine) : J. 

 Savornin. — The Dinosauria of the Jurassic in Madagascar : 

 Armand Trevenin. — The characteristics of the leaf trace 

 of An];yropti'ris Ilibractensis : Paul Bertrand.
