criticisms need not be further considered here but it may be of interest to 

 compare the conductance values calculated according to Ghosh's theory 

 with those experimentally determined. 



For the conductance of an electrolytic solution Ghosh's theory leads 

 to the following equation:

 from the ionization of the neutral molecules and upon the number of 

 charges associated with a single ion, as well as upon the manner of dis- 

 tribution of these ions in the solvent medium. It is evident that, for a
