From these results M. Violle concluded that the absorptive effect due 

 to water vapour was about five times as great as that due to dry air ; 

 but when the constant C, of the logarithmic formula for the vertical 

 distribution of the absorbent substance is computed, it is found to be 

 22,137 feet on the 16th August and 22,580 on the 17th. These 

 numbers agree so closely with the mean of those found above, and 

 with the constant of the average vapour formula found by Dr. Hann.f 

 viz., 6,517 metres or 21,382 feet, that it is evident that in the Alps, as 

 in the Himalayas, practically the whole absorptive power of the atmo- 

 sphere is exercised by the water vapour it contains.
