molecular conductivity of the simple solutions at infinite 

 dilution. Owing to the want of this datum, I have drawn the 

 curves a /V = < (V) by means of data based on Kohlrausch and 

 Grotrian's and Kohlrausch's Observations of the conductivity of 

 solutions of these salts. They are as follows : 



NaCl SOLUTIONS. 



KC1 SOLUTIONS. 



It will be seen that the above data are quite sufficient for 

 drawing the curves representing a /V as <J>(V) in the parts 

 corresponding to small dilutions ; but that the data are few for 

 the parts corresponding to the greater dilutions, where the 

 curvature is more rapid. In order to draw these parts of the 

 curves therefore, I obtained interpolation formulae, expressing a/V
