VISCOSITY AND FLUIDITY OF ACETONE MIXTURES. 



Molecular conductivities are indicated in the conductivity tables, and V is the 

 number of liters of solution containing a gram-molecule of the electrolyte. The 

 temperature coefficient of conductivity is the change in molecular conductivity per 

 degree, divided by the molecular conductivity at 0. 



The first compound that we studied in this connection was lithium nitrate, and 

 the sample used was Kahlbaum's preparation, which, after testing, was dried to 

 constant weight at 150.
