FLUIDITY AND PLASTICITY

perfectly with the values 0.683, 0.785, and 0.897 obtained from
the observed fluidity data for each mixture. The values of k
in the Batschinski formula are 2,019, 1,937, 1,845 as calculated
from the pure solvents, as compared with 2,034, 1,993, and 1,876
as obtained from the data for the mixtures. The values of
the fluidities calculated by means of the former set of
constants are not so close to the observed values as are the values
calculated by the corrected fluidity formula. But they are at
least as close to the observed values of the mixtures as the cal-
culated fluidities of pure carbon tetrachloride are to the observed.
It is impracticable here to consider in detail all of the examples
