The following communications were read ; — 

 I. " On the Combustion of Hydrogen and Carbonic Oxide in Oxygen 

 under great pressure." By E. Frankland, F.R.S., Professor of 

 Chemistry in the Royal Institution and in the Royal School of 

 Mines. Received June 11, 1868. 



In a former communication to the Royal Society* I described some re- 

 searches on the effect of a diminution of pressure on some of the phe- 

 nomena of combustion, and deduced therefrom the law that the diminution 

 in illuminaVmg-jiower is directly projjortional to the diminution in atmo- 

 spheric pressure. 



Further experiments, made more than a year ago, on the nature of the 

 luminous agent in a coal-gas flamef, led me to doubt the correctness of the 

 commonly received theory first propounded by Sir Humphry Davy|, 

 that the light of a gas-flame and of luminous flames in general is due to
