striking proof of the essential soundness of the theoretical views on 

 which the calculations are based. 



It should be noted that while the values of K^-^Ko for NaCl 

 and for CaCL fit the general scheme, the absolute values of iii and 

 K2 in these cases are much greater than we should expect. This 

 shows that in pure CaClo something accelerates both A ^ M and 

 M-^B to an equal degree {i. e., multiplies both K^ and Kn by the

same factor) ; the same is true of NaCl, but here the acceleration 

 is much greater than in CaCL. This acceleration might be due 

 to a variety of causes and it seems unncessary to discuss it more 

 fully at this time. 



Figs. 10 and 11 show the curves of resistance in NaCl and in 

 CaClo and the curves calculated from constants obtained by trial. 



Let us now consider briefly an alternative explanation of these 

 results-
