252 .0/1 Oxalic Acid. 



When these different elements are collected under their 

 proper heads, we obtain 



Grains. 



1. Oxygen in carbonic acid 42*86 



— — inflammable air 11*96 



— — water - - 9'87 



6J-69 



£?. Carbon in carbonic acid 16*67 



— — inflammable air 10*43 



— — charcoal - 4*68 



31*78 



3. Hydrogen in inflammable air 1*89 

 — — — water - - 1*64 



3*33 



Hence oxalic acid is composed of oxygen 64*69 



— — — — ■ — — — carbon 31*78 



— — — — — — — hydrogen 3*53

7. The result of two other experiments on oxalate of lime 

 was very nearly the same as the preceding. The following 

 may be stated in round numbers as the mean of the whole. 

 Oxalic acid is a compound of 



Oxygen - 64 



Carbon - 32 



Hydrogen - 4

8. The only other analysis of oxalic acid with which T am 

 acquainted has been given by M. Fourcroy, as the result of 

 his own experiments, in conjunction with those of Vau- 

 (juelin*. It is as follows :
