It is clear from the figures which have been obtained from 

 Mathison's blood that the effect of altitude has been to increase the 

 acidosis to a very marked extent. 



And now as to the nature of the acidosis ; so far as a single experi- 

 ment can settle that point, the following figures show that the 

 acidosis, produced by exercise at high altitudes as at low ones, is a 

 lactic acidosis. 



Acidosis in Camis s blood. 



As to the length of time taken for the effects of his exercise to 

 pass off we have but scanty data. Here again we must distinguish 

 between the acidosis and the meionexy. 



Changes observed as the result of ascent of WOO feet by 



Before the climb began Mathison was mesectic. Immediately after 

 the exercise there was considerable excess of acid in the blood and no 

 diminution of CO 2 in the alveolar air. This of course meant a total 

 reduction in the alkalinity of the blood, and consequently a meionectic
