5. Muriate of lime. This salt is easily formed 

 by saturating muriatic acid with lime. It is so 

 soluble and deliquescent as not to be easily crys- 

 tallized. Yet I have frequently obtained it in 

 regular transparent crystals and they may be 

 obtained at any time by putting a strong solu- 

 tion of it under the exhausted receiver of an air 

 pump, along with sulphuric acid to absorb the 

 vapour as it flies off. These crystals are four- 

 sided or six-sided prisms, striated longitudinally, 

 and bearing a considerable resemblance to the 

 crystals of sulphate of soda. The constituents o 

 these crystals are the following : 



1 atom muriatic acid 4-625 

 1 atom lime 3-5 



6 atoms water 6-75 



14-875 



When these crystals are exposed to a red heat, 

 not only the water, but a portion of the acid is 

 apt to make its escape, However, I have re- 

 peatedly succeeded in rendering the crystals an-
