On Oxalic jicid. 



lOg 



8, To determine the composition of these salts, I took 

 seven difftrent portions of a diluted oxalic acid solution, 

 each weiiihiiig 100 grains, and containing seven grains of 

 real oxalic acid. To each of these portions I added respec- 

 tively potash, soda, ahnnonia, barytes water, strontian wa- 

 ter, and lime water, til! it ceased to produce any change. 

 The liquid was then evaporated to dryness, and the residue, 

 after being well dried on the steam bath. Was weighed. 

 Kach of these salts contained seven grains of acid ; the ad- 

 ditional weight I ascribed to the base. Hence I had the fol- 

 lowing table, which exhibits the weight of each salt obtained, 

 and its conjposition deduced from that weight.

The composition of these saUs reduced to 100 parts, is
