ON OLEFIANT GAS. 



Of the 302 cubic inches of oxygen gas consu r 

 Hied, 208 went to the formation of carbonic acid. 

 The remaining 94 cubic inches must have gone 

 to the formation of water, and they must have 

 combined with a quantity of hydrogen, which, if 

 in the gaseous form, would have amounted to 188 

 cubic inches. Therefore, 100 cubic inches of 

 defiant gas, are composed of the carbon in 208 

 cubic inches of carbonic acid, and a quantity of 

 hydrogen equivalent to 188 cubic inches. 



Now, the carbon in 208 inches of carbonic acid 



, weighs - - 26.98 grains. 



108 inches of hydrogen gas weigh 4.80 



Total, 31-78. 

 Weight of the ole riant gas, 2 9-72 



Surplus, 2.06 



Thus the weight of the constituents found 

 by analysis, exceed that of the olefiant gas by 

 about T yth part; — a clear proof that olefiant gas 

 contains no oxygen. The science of chemistry, 

 in its present state, admits of no stronger proof 

 than what we have now given. 



It follows from the preceding analysis, that 

 olefiant gas is composed of about 



Carbon, - 85 



Hydrogen, 15
