Oxalate of Copper and Am'moma,^tij0, C2 O3 + CuO,C203 



+ 2HO = 156-38.— The solution of 18-3 grains gave an in- 

 crease of 8*6 at 65°; this gives 73 '3 as the volume of this salt 

 when in solution. 



^' 'On immersing 20 grains in turpentine, an increase of 10*4 

 Was obtained, which gives for the volume of the equivalent 

 81"3, and for the specific gravity of the salt 1'923. 



Quadrowalate of Potash, KO, Cg Og + SHO, C2 O3 + 4HO 

 = 255*11. ^32*0 grains dissolved in water, gave an increase 

 of 15*0 at 60° ; and a second experiment, in which 16 grains 

 were dissolved in 1000 grains of M'ater, gave the increase of 

 7*2 at a temperature of 44°.

Quadroxalate of Ammonia, KO, Cg Og + 3HO, Cg Og + 4H0 

 = 234*15. — On dissolving 20 grains of this salt in 3500 grains 

 of water at 50°, the increase is 11*5, which gives 134*5 as the 

 volume of the equivalent in solution. 



58*5 grains of the salt, thrown into a saturated solution, 

 caused in the first experiment an increase of 36*8, in tlie 

 second of 36*9, both at a temperature of 62°.
