It is curious that, in these experiments, the whole of the 

 gas was never consumed — a proof that the combustion is most 

 complete, when a considerable quantity of azote is present. 

 It is indeed possible, though not probable, that the constant 

 residue was incombustible. We have no means of verifying 

 this by experiment. From the preceding table we deduce the 

 following, which exhibits the proportion of gas and oxygen 

 consumed, and of carbonic acid formed.
