ISOMERIC MIXTURES.

With the nitrogen monoxide, the velocity found by experi- 

 ment is near the theoretical value for compounds containing 

 hydrogen or cyanogen. With carbonic oxide we find the same 

 anomaly as with oxygen. 



6. One of the most interesting examples, and one most strongly 

 confirming the theory, is the case of the isomeric compounds, 

 i.e. those in which the composition of the final system is the 

 same. In fact, in these cases the influence of the individual 

 nature of the combustible gases, and even that of the combustive 

 ones, is eliminated.
