:~The same quantity of salt, 45*8 grains, thrown into a satu- 

 rated solution, caused an increase of 12*0 in one experiment 

 and of 12-4 in two other trials, the temperature in all the 

 cases being 58°.

Chloride of Mercury and Sodium, NaCl 4- 2HgCl + 4HO 



= 368-5. — On dissolving 46-06 grains of this salt in lOOOgrains 



jsiO-sif of water, the increase was 12*4 at 63°. This gives for the 



equivalent a volume of 99*2, or 1 1 equivalents. The same 



quantity of salt thrown into turpentine produced an increase 



of 15 3, which gives for the equivalent 122-4, and for the spe- 



j cific gravity 3*011. 



Y' I A careful consideration of the previous experiments shows
