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



2. Hydrogen in Water. 

 The gas was prepared from dilute sulphuric acid and pure zinc. 



From these experiments it is seen that the mean coefficient of 

 absorption 0-0193 of hydrogen is constant for temperatures 

 from 0° to 20°. 



3. Mthyle Gas in Water. 



For these experiments a quantity of the same sethyle gas was 

 employed, which Professor Frankland prepared in my laboratory 

 some years ago, and of which he gave the analysis in his research 

 on the aether radicals. 



By combination of the experiments 1, 2, 3 ; 2, 3, 4 ; and 



3, 4, 5, the following interpolation formula is found, 



c=0-03M74-0-0010449< + 0-000025066/ 2 , 

 by means of which the following Table is calculated : —
