of the + and — ions respectively among themselves, in both the 

 author's and Kohlrausch's tables, the ratios thus obtained agree 

 closely in the respective tables. It will be evident that, if the 

 values of the H ions as calculated by the author were lowered so 

 as to equal Kohlrausch's numbers, the values of the + ions would 

 also be lowered and those of the — ions raised so as to approach 

 Kohlrausch's figures. The author finds that by using the general 

 formula 



K=/XVHX-r-/^tfaOH— ftVtfaX, 



the calculated quantities approximate more nearly in value Kohl- 

 rausch's figures. 



In the tables ju^k = 1*0 and ^y cl = l'0 respectively have been 

 chosen for the purpose of calculating the ratios.
