The remaining series of experiments, three in number, relate to the ratio 

 2Ag : MgCL, which was earlier investigated by Dumas. For the elaborate 

 details of manipulation the original memoir must be consulted. I can 

 give little more than the weights found, and their reduction to the usual 

 form of ratio, Ag„ : MgCl. : : 100 : x :

This series gives slightl}^ higher results than the others, and the 

 authors, for reasons which they assign, discard it : • 



The fourth series, because of the experience gained in the conduct of
