Kanitz regards his observed values as affected by a possible 
error of + 3in the third decimal place. Considering the many 
calculations necessary to obtain the calculated values,—first, in 
finding the specific molecular conductivity at infinite dilution for 
25°C., and also ionization coefficients at 25° from data at 18°, 
and then in the determination of the ionization coefficients of 
the salts in the mixture by the graphical method,—the agree- 
ment between the observed and the calculated values (calculated,
