LIST OF GASES EXPLODED. 159 



of the combustion of the following thirty gases and vapours, all 

 combustible bodies. 1 



Hydrogen. 



Carbonic oxide. 



Hydrocarbons, such as methane, ethane, ethylene, acetylene, 

 hydride of propylene, propylene, allylene, benzine, dipropargyl, 

 diallyl. 



Oxygenated compounds, such as methylic ether, glycolic 

 ether, aldehyde, methylformic and ethylformic ethers, dimethylic 

 methylal. 



Nitrated compounds, such as cyanogen, hydrocyanic acid, 

 trimethylamine, ethylamine. 



Chlorated, bromated, iodated compounds, such as methyl- 

 chlorhydric, methylbromhydric, methyliodhydric, ethylchlor- 

 hydric and ethylbromhydric ethers, chlorides of methylene and 

 ethylidene. 



Sulphuretted compounds, such as carbon disulphide. 



It has also been used by an inverse process to measure the 

 heat of formation of the combustive gases, such as nitrogen 

 monoxide, and nitric oxide (p. 149), the heat of formation 

 of these gases being deduced from the difference between the 

 heats of combustion of the same carburetted (carbone) gas by 

 pure oxygen on the one hand, and by the oxygenated gas on 

 the other.
