Calculation for Oxygen. 
We do not calculate upon the tube from gasometer B, 
because it is always in the same state after the experiment as 
before. 
1000 cubic inches of oxygen containing 
5 per cent, azote, consisted of 950 pure oxygen 
60 Atmospheric air with the pig, and in 
tube C, containing 21 per cent, oxygen 12,60 
Total, oxygen before experiment, 962, 60 
Oxygen found after experiment, 801,75 
Ditto in carbonic acid - 106,78 
908,53 
Oxygen missing, 54,07 
Calculation for Azote. 
1000 cubic inches containing 5 per 
cent, azote 50 
60 Atmospheric air, containing 79 per cent. 47,40 
Total azote before experiment, 97,40 
Ditto found after experiment, 147,52 
Increase of azote, 50,12 
This increase of azote was much more than equal to the cubic 
contents of the animal's body, the deficiency of 4 cubic inches 
was doubtless oxygen absorbed.
