The temperature of combustion was low — probably not above 

 1000°. These experiments confirm the view that the first stage of the 

 combustion of carbon is the formation of the lower oxide. The minia- 

 ture explosion in this reaction may have removed the carbon monoxide 

 from the seat of the reaction so quickly, that its temperature was too 

 low for the complete formation of carbon dioxide, although oxygen 

 was present in excess. We hope to extend our observations on this 

 incomplete combustion.
