5. Arseniate of lime. This salt may be formed 

 by dropping arsenic acid into lime water. It is 

 a white anhydrous tasteless powder, composed of 



1 atom arsenic acid 7*75 



1 atom lime . . 3-5

There is, likewise, a binarseniate of lime which 

 crystallizes ; but I have not subjected it to ana- 

 lysis. 



6. Chromate of lime. This is rather a fine 

 yellow powder, which is insoluble in water and 

 anhydrous, it would probably answer as a pig- 

 ment. Its constituents are 



1 atom chromic acid 6-5 



1 atom lime . . 3*5

7. Tungstate of lime. This salt, which is oc- 

 casionally met with in native octahedral crystals, 

 is likewise anhydrous, and is undoubtedly a com-
