Composition of '' Sulpho-arsenate Powder." 



An analysis of the preparation known as Sulpho-arsenate Powder shows 

 it to have the following composition : — 



10000 

 If the lead and arsenic acid found existed as lead arsenate, then we would 

 Lave 23-46 grams diplumbic arsenate and 22-87 grams triplumbic arsenate 

 present. 



The sulpho-arsenate powder appears to consist of 46i per cent, lead arsenate, 

 24 per cent, sulphur, diluted with lime compounds (oxide hydrate and 

 carbonate). It will be noted that the preparation is to be used as a dry 

 yjowder for dusting. — A. A. Ramsay, Principal Assistant Chemist.
