THE EXPLOSIVE WAVE. 



assumed to be in the gaseous state in the hydrocarbons, a con- 

 dition that does not enter into the case of carbonic oxide or 

 cyanogen. 



Thus it seems to be an established fact that the proposed 

 formula represents approximately the velocity of the explosive 

 wave for hydro-carbon gases. 



5. This conclusion may be extended to the mixtures formed 

 with these gases and hydrogen, or even carbonic oxide, as will 

 be shown, the hydrogen imparting to these mixtures a law of 

 detonation similar to its own.
