pressures varying from 40 to 300 atmospheres, it was again analysed as it existed in 
the tube, and found to consist of 
3 vol. COo and 4 ’02 vol. N. 
In the following Tables p is the pressure as indicated by a hydrogen-manometer, 
t the temperature of the manometer, e a fraction representing the ratio of the volume 
of the mixture after compression to its volume at the temperature t' under one atmo¬ 
sphere, t! the temperature of the mixed gases, and 6 the volume which 1 volume of 
the mixture measured at 0° and 760 millimetres would occupy, at the temperature at 
which the observation was made, and under the pressure indicated by the hydrogen- 
manometer.
