The absolute values of viscosity vary considerably with the 

 temperature, but the values of Tj remain nearly constant. For 

 the sake of easier comparison all the results including those at 

 25° are collected in the next table.

 Value of Tj. 



As may be seen, the general course of coagulation with the 

 increasing concentration of the electrolyte remains nearly the
