If we calculate the oxygen consumption for one hour, to com- 

 pare the results of these two experiments more easily, we find that 



Oxygen CO 



A, at normal pressure, consumed 278 cc, and formed 237 



a, at normal pressure, consumed 282 cc, and formed 246 



b, at 50 cm. pressure, consumed 246 cc, and formed 237 



c, at 37 cm. pressure, consumed 227 cc, and formed 180 



B, at 34 cm. pressure, consumed 221 cc, and formed 175 



C, at 20 cm. pressure, consumed 160 cc, and 'formed 138 



The remarkable agreement between experiments A and a on 

 the one hand, c and B on the other, shows that, in spite of the 

 causes of error inherent in our experimental procedure, — causes 

 of error which compel us to disregard the third figure in the num- 

 bers reported above, — we can state definitely that the oxygen con-
