Hallez. — The influence of high altitudes on the general 

 nutrition : H. Guillemard and R. Moog. The observ- 

 ations were carried out at Paris, at the Grand Mulets 

 (3050 metres), and the summit of Mt. Blanc (4810 metres), 

 the changes in the urine being more specially examined. 

 It was found that the effect of high altitudes on nutrition 

 was to produce a diminution of the oxidation processes, 

 diminution of diuresis, and retention of the fixed elements.

 Experiments on dogs leads to the conclusion that the spleen
