No. 1, is liquid at 140° ; on cooling, it forms a solid mass of 
needle crystals. No. 2, is liquid at 85°, and solid at 55 0 . In 
the liquid form at the temperature just mentioned, it is of 
specific gravity 1.98. No. 3, is liquid at 55 0 , and of specific 
gravity 1.58. No. 4, is liquid at about 105°; on cooling 
slowly to 6o°, it deposits some crystals which are four- 
sided prisms, composed of facets alternately broad and 
narrow. 
That corrosive sublimate and muriate of ammonia have 
a strong affinity for each other, is evident from the circum- 
stance, that united, the solubility of the compound exceeds 
that of the most soluble ingredient. This is proved by the 
solubility of the 3d compound just described : farther in proof, 
it may be mentioned, that a saturated solution of muriate of 
ammonia at 60°, is capable of dissolving its own weight very 
nearly of corrosive sublimate, and that after this addition it is 
capable of taking up more muriate of ammonia ; thus, 25.3 
grains of such a saturated solution, after having taken up 
25.1 grains of corrosive sublimate, dissolved 7 grains more 
of muriate of ammonia. From this experiment it would ap- 
pear, that corrosive sublimate is about 17 times more soluble 
in a saturated solution of muriate of ammonia than in water, 
and not 30 times, as is stated by some authors. 
The results of these experiments led me to make trial of 
some other muriates, as of baryta, magnesia, potash, and 
soda. 
A saturated solution of muriate of baryta, formed of 20 
grains of water and of 8.7 grains of the crystallized salt,* 
dissolved 16 grains of corrosive sublimate at 6o°, and 4 grains 
* 8.7 grains of this salt, heated nearly to redness, lost 1.4 grain water of crystal- 
lization.
