siura and oxygen. The calculated percentage of CI and Sb from the 

 data given were, however, invariably corroborated by an estimation of 

 the total Sb and CI. 



The crystalline form of each salt is represented by the free hand 

 sketches, and the accompanying stereographic projections show more 

 accurately the mathematical relation of the planes.

These crystals were quite permanent in the air, presented no diffi- 

 culty in manipulation, and allowed very close measurements with the 

 reflecting goniometer. 



The salt is decomposed immediately by hot or cold water ; insoluble 

 in hot or cold saturated solution of potassic chloride, hot or cold bi-
