portion of its carbon, and formed a new inflam- 

 mable gas, amounting to 82.7 measures in bulk, 

 or almost double the bulk of the two gases that 

 went to form it. 



The new inflammable gas being examined by a 

 new mixture witb oxygen gas, and a new detona- 

 tion, was found to consume 73 per cent, of oxygen 

 gas, and to form 55 per cent, of carbonic acid. 



Hence the 82.7 measures would have form-

From this it would seem, that about ^th of the 

 carbon removed by the first explosion, is convert- 

 ed into carbonic acid, while -|ths precipitate in the
