we shall first calculate the total quantity of azote existing in 
the gas before the experiment, and afterwards estimate what 
was produced in the different periods during the first half of 
the experiment. 
Calculation for Azote. 
2668 cubic inches of oxygen were employed containing four 
per cent, azote : then 
100 : 4 : : 2668 : 106,72 
the total quantity of azote in the gas consumed, was 106,7* 
cubic inches.
