Of these experiments, the 1st, 2d and 5th are 

 the only ones from which the proportion of oxy- 

 gen consumed, and of carbonic acid formed, can be 

 deduced. They were repeated very often, in or- 

 der to insure as much accuracy as possible. The 

 following is the result which they give : 



Inflammable 

 gas consumed. 



Oxygen gas 

 consumed. 



Carbonic acid 

 gas formed.
