XXII. Mixture of Air and Olefiant Gas^ containing per cent, 
hy volume of Olefiant Gas. — The absorber, containing the same gas 
as in the Experiments XIX,, XX., and XXL, was surrounded by- 
water at 12° *8 C., and the pressure when constant was found to be 
9305-6. Dry olefiant gas was then driven in until the pressure had 
taken the constant value 9318*3. The mixture therefore contained 
*19969 or about *2 per cent by volume of olefiant gas.

Mixture of Air and Olefiant Gas, containing per cent. 
hy volume of Olefiant Gas. — The absorber, containing the same 
mixture as in Experiment XXII., was surrounded by water at 
12° *8 C., till the pressure had assumed a constant value. Then as 
usual the water was turned off from K, and the steam turned on.
