mn ON OXALIC ACID. 



24*28 grains of the inflammable air, accovcling to the ana- 

 lysis given in a preceding part of this paper, are composed

Hidrogen 1"64 



11-51 



As for the charcoal, though it probablj- contains both 

 •xigen and hidrogen as well as carbon, yet as the propor- 

 tion of the first two ingredients is probably very small, and 

 as we have no means of estimating them, we must at pre- 

 sent rest satisfied with considering it as composed of pure 

 carbon. 



When these different elements are corrected under their 

 proper heads, we obtain 



Oxigen. Carbon. Hidrogen.
