11. Influence of Chemical Affinity on the Alsorption of Gases. 
If such an influence did not exist, the gases would be absorbed 
by all liquids in the same order. As I had not perceived any distinct 
difference between water and alcohol in this respect, I tried other 
liquids, and I confined my experiments to four gases, namely, car- 
bonic acid, nitrous oxide, olefiant gas, and carbonic oxide, I ex- 
cepted oxygen gas from these experiments, because it forms perma- 
nent compounds with most of the liquids to be employed, which are - 
not modified by the pressure of the atmosphere. Azotic and 
hydrogen gas were also excluded, because they are absorbed in such 
small quantities that the difference in the rate could not be accu- 
rately ascertained. The experiments were made at the temperature 
of 64°5°.

It follows from these experiments, that in liquids, as well as in 
solid bodies, great differences take place in the order in which gases 
are absorbed by them, and that in consequence these absorptions are 
always owing to the influence of chemical affinity.
