If we assume that the amount of chloride of silver precipitated 
by nitrate of silver under the conditions described above is a 
forrect measure of the solubility of the chloride, it appears 
Prompt settling of the chloride of silver or to wash away any 
occluded material, and it was the chief object of this investi- 
ion 
chloride in distilled water might effect the result. For this 
Purpose
