these observations. — C. V. L. Charller : The construc- 

 tion of the galaxy. Charts are given showing the 

 projections of the group of star's of spectral class B 

 (helium stars) in three directions. — A. Plctet and P. 

 Stehelin : The formation of pyridine bases by condensa- 

 tion of ketones and amides. Following the 

 analogy of the formation of mesitylene, an attempt 

 was made to prepare pyridine by the condensation of 

 acetone and acetamide. The experiment failed with 

 the usual dehydrating reagents, but pyridine (2 to 

 3 per cent, yield) was obtained by heating in sealed 

 tubes to 250° C. — B. Galitzine : The localisation of the 

 epicentre of an earthquake from observations at a 

 single seismic station. — L. Eble : The deviations from 

 the vertical at Paris. — J. Cardot : The bryological flora 

 of Kerguelen. This flora presents close analogies 

 with that of South Georgia. — MM. Neveu-Lemaire, 

 Debeyre, and Rouvifire : A prolonged form of cerebro- 

 spinal meningitis and cerebral trepanning. A descrip- 

 tion of a case in which the injection of antimeningo- 

 coccic serum into the right lateral ventricle was re- 

 sorted to, resulting in a complete cure. — F. Bordas : 

 Ozonised oxygen in the treatment of war wounds. 

 The wounds are kept in an atmosphere of ozonised 

 oxygen, without dressings, and exposed to solar radia- 

 tion. The results have been particularly satisfactory 

 in large wounds where the tissues had been invaded 

 more or less deeply by septic products and anaerobic 

 fermentations. The treatment can be prolonged without 

 inconvenience to the patient, and the general appear- 

 ance of the wounds rapidly improves, the fetid smells 

 disappearing at the very commencement. — J. Amar : 

 The sense education and utilisation of mutilated 

 limbs.
