The Same, Continued.—The preceding solution diluted with an equal bulk of water showed the density p= at 21° or grams in 100 grams of solution, grams in 100 grams of water, corresponding to the vapor pressure 7r' = 7r(i—). The record of results is contained in table 33 and fig. 29 and is very pecu- liar. Even apart from the usual irregularity at the beginning of the obser- vation period, the curve continues to be sinuous after the weekly method of observation is introduced. The mean value is probably that of pure water, though the whole behavior is abnormal. The mean diffusion rates are i'o = or 10^^ = a value even in excess of the usual air value. If the final rate were taken the diffusion constants would be ^5 = or 10^^ = which is more nearly the probable result. Table 33.—Air into air through CaClo solution ( grams in 100 grams water).

The concentrated solution of BaCl2 showed a density of p^^, = i. 170 at 20° C, therefore equivalent to 17 grams of BaClo in 100 grams of solution or grams in 100 grams of Vv^ater.
