clusively in the methyl group; the para-derivative behaves 

 similarly. — Researches on the aS -dimethylglutaric acids, by 

 M. E. E. Blaise. — The preparation and properties of i : ii 

 hexanediol or hexamethylene glycol and its principal deriva- 

 tives, by M. l'Abbe J. Hamonet. Diphenoxyhexane is con- 

 verted into diiodohexane by the action of hydriodic acid, 

 and from this the acetin is obtained and hydrolysed, yield- 

 ing the glycol, the properties of which are described. — Con- 

 tribution to the physiology of the internal ear, by M. 

 Marage. The experiments described are not in exact 

 accordance with either of the current theories of audition. 

 A third theory is developed, one of the consequences of 

 which is that the variations of pressure in the internal ear 

 are of the same order as actions affecting other nerves. 

 The acoustic nerve thus ceases to be exceptional in its 

 behaviour. — The evolutine cycle of tissues deprived of their 

 intimate relations with nerves, by M. N. Alberto Barbieri.
