268 INFLAMMABLE GAS. 



Experiments smaller specific gravity than the first portion, the following ex-

It Is remarkable that, in these experiments, the residual gas 

 was always the same. This renders it probable that it was 

 incombustible, and that it differed in its nature from the gas 

 which was consumed. The following table exhibits the quan- 

 tities of gas and oxygen consumed, and of carbonic acid 

 formed, in each experiment.
