non polymerise est null. ” The accuracy of this statement will be¬ 
come manifest when the following table is examined. In Table 
XXXVI are arranged the names of a number of solvents in the 
order of increasing coefficients of association. The names appear 
in the first column, the coefficient of association in the second. 
These values were mostly determined by Ramsay and Shields. 
(See Table I.) The third column contains the dielectric con¬ 
stants taken from Table I; and the fourth column contains the 
viscosity factors, rj, as far as they could be obtained from the 
tables of Dutoit and Friderich and of Landolt and Bornstein. 
The last three columns contain the salts, the volume in liters in 
which our gram-molecule was dissolved, and the molecular con¬ 
ductivity at this particular concentration. That salt was usually 
chosen that gave the largest value for fx.
