views of NERNOT, and the method may be farther employed to test directly the 

 potential differences between equally concentrated salts of the same metal. It will 

 be shown below that there are apparently cases in which the method can still be 

 applied even when the metals of the solutions are different. 



The agreement for the half-normal solutions is less complete than for the more 

 dilute solutions. This may be partly due to the fact that the observed E.M.F. of the 

 cell was more uncertain in this case than in the others ; but a much more probable 

 explanation lies in the fac that the difference between the coefficients of ionization 

 for KI and KC1 respectively becomes appreciable when the solutions are not dilute. 

 Before examining the effect of such a difference further, I will give the results ot 

 experiments upon some of the other solutions mentioned by NERNST.

 to those already described.
