DISCUSSION OF RESULTS. 



A rise in temperature causes an increase in conductivity, which may be due to 

 either or to both of the following causes : first, an increase in the number of the ions 

 present, and second, an increase in the velocity of the ions. That the number of the 

 ions does not generally increase with rise in temperature has been shown by direct 

 measurement of the degree of dissociation by means of the conductivity method.

This is in accord with the theory of Dutoit and Aston, which makes the dissociating 

 power of a solvent a function of its own association. The degree of association of a 

 solvent has been shown by the method of Ramsay and Shields to decrease with rise
