The proportion of oxygen required by this supposition, does 

 not differ much from that consumed by the gas from peat ; but 

 the carbonic acid is more than is formed by the gas from peat. 

 The diminution of bulk is too small. And, upon the whole, 

 the differences are greater than can bo ascribed to errors in the 

 experiments. 



(2) According to the second hypothesis, the gas from peat is 

 a mixture of carbonic acid and hydrogen.

We have, as before, x',y:: c — b : a — c. From this we ob- 

 tain, as before, a=83.57 and j/= 16.43. So that, if this hy- 

 pothesis be true, the gas from peat must be a mixture of
