7. By dissolving given weights of these crys- 

 tals in water, and taking the specific gravity of 

 the solutions at 60, I was enabled to form the 

 following table, exhibiting the specific gravity 

 of various atomic compounds of this acid and 

 water : 



SP. GR. AT 60,

Table exhi- 

 biting the 

 specific gra 

 vity of ace- 

 tic acid of 

 different 

 strengths, 



We see from this table that the specific gravity 

 of the liquid is a maximum, when it consists of 

 1 atom acid united to 4 atoms water ; or, when 

 it is composed of

We see, too, that the specific gravity of acid, 

 containing only 1 atom water, is nearly the same 

 with that containing 7 atoms water ; or the two 

 following compounds
