CONDUCTIVITY AND VISCOSITY IN MIXED SOLVENTS. 



work of Thorpe and Rodger, 1 and these values were used as the basis for the 

 calculation of all the values given in tables 84 to 86. 

 The fluidity values were calculated from the following formula : 



1 



n 



in which <f> is the fluidity, and n is the corresponding viscosity value. In other 

 words, the fluidity values are simply the reciprocals of the viscosities. All 

 the values given in tables 84 to 86 have been obtained both for pure solvents 

 and solutions, using the modified form of viscometer which has been already 

 described. Many of the values given have been carefully checked by using 

 entirely different solutions in the several determinations.
