Conductivities and Viscosities in Pure and in Mixed Solvents. 



The explanation of the above phenomena observed by Jones and his 

 co-workers follows directly from and substantiates the suggestion made 

 by Jones and Veazey. 



APPARATUS AND PROCEDURE. 



In carrying out this investigation, the same viscosity apparatus was 

 used as in our work with formamid as a solvent, recorded in Chapter II 

 of this monograph. The scheme of temperature regulation and the 

 methods of obtaining the results were also identical with those used in 

 that work. 



The caesium salts were all carefully recrystallized and dried at 135 

 before using. 



The mixed solvents were made up by volume at 20, from liquids 

 purified by the usual methods, and all solutions in these liquids were 

 prepared at the same temperature.
