Dr. Gr. Gore on a New Method and 



tap was closed during the process of changing each strength 

 of liquid. In consequence of the much greater conduction 

 resistance in the constricted portions of the solutions, the 

 degrees of electromotive force were all much smaller than if 





the two metals had been near each other in the same leg. The 

 following are the results obtained with solutions of KBr and 

 NaCl :—
