M. R. Bunsen on the Law of Absorption of Gases. 187 



eudiometrical analysis, it may be concluded that the formula; 

 based upon the original premises are true, and that the law is 

 not only applicable for total, but also for partial pressures. 



Mixtures of carbonic acid and hydrogen were employed in the 

 following experiments : — 



Experiment I. 

 Eudiornetric determination. 



Composition of the gas in 100 parts : — 



Hydrogen .... 92-46 

 Carbonic acid . . . 7*54 



Mean .... 356-4. 



From tbis the following elements of the calculation are ob- 

 tained : — 



P = 005368; P, = 0-6809; « = 1-4199; h = 356-4; 

 V=171-29; V, = 119-61; £=0-0193; 

 and hence the composition, —
