7O ELECTROCHEMICAL INVESTIGATION OF LIQUID AMALGAMS 



the labor involved, especially as the chance of error increases greatly as 

 the amalgams become more dilute. The possible appearance of a balanced 

 reaction at great dilution we attempted to detect by using, not greater 

 dilutions, but rather metals with the least possible solution-tensions. The 

 interesting work of Hulett and De Lury, published after ours was com- 

 pleted, supplements our work by carrying the curve of one of the metals, 

 cadmium, much further to the right than we have done. Neither of our 

 curves shows any certain indication of the balanced reaction for which 

 Hulett and De Lury were independently seeking, although several of the 

 metals are distinctly less electropositive than cadmium. 



In conclusion, we take pleasure in expressing our obligation to the 

 Carnegie Institution, of Washington, for generous pecuniary assistance.
