524 ON OXYCARBURETED HYDROGEN. 



Hence 100 cubic inches of it would weigh 

 14.66 grains, and its specific gravity cannot ex- 

 0.4808. 



This is on the most unfavourable supposition, 

 that no water whatever is formed during the first 

 combustion. If water be formed, it is obviously 

 lighter than we have made it. It is clear, there- 

 fore, that this new-formed gas, to which the name 

 of Oxycarbureted Hydrogen may with propriety 

 be given, is quite different from carbonic oxide 

 gas, the specific gravity of which is 0.95$, or al- 

 most double of our new gas. 



9.87 grains of olefiant gas are 



composed of - 1.49 hydrogen. 



8.38 carbon.

Hence our oxycarbureted hydrogen gas is com- 

 posed of - 1.49 hydrogen.
