This formula is of the same form as those given by the first 

 and second hypotheses, so that all three lead to the same re- 

 sults when there is chemical equilibrium. 



We might apply similar principles to any case of gaseous 

 combination ; but after what has been given the reader will, 

 I think, have no difficulty in forming for himself the equations 

 which hold for any particular case. In conclusion, I may say 

 that much of the reasoning would seem to be applicable to 

 liquids, and we should expect many of the formulae to be 

 approximately true for the combination of liquids as well as 

 of gases, though we know so little about the molecular com- 

 position of liquids that it is difficult to base the reasoning in 

 this case on direct dynamical principles.
