 Ethane and Oxygen undee High Peessuees. 



^^ detonation^'' are responsible for the more complete breaking down of 

 unsaturated hydrocarbons, and a greater " unburning " of steam by 

 carbon, but there is probably no difference as regards the mode in 

 which the hydrocarbon is attacked by the oxygen in the two cases. 



I therefore believe, that, so far as our pi-esent knowledge goes, the 

 views I have put forward, afford a simple and consistent interpreta- 

 tion of hydrocarbon combustion, whether it be the slow flameless kind 

 discovered by Davy, or the more complex phenomena of ordinary 

 flames so wonderfully expounded by him, or linally the extreme con- 

 ditions characteristic of the explosion wave.* 



* I desire to acknowledge the devoted help rendered to me in the conduct 

 of these investigations by the following research students of the Manchester 

 University : Messrs. R. V. Wheeler, W. E, Stockings, G. W. Andrew, Julien 

 Drugman, and H, Henstock.
