The equivalent conductivities of N/2 and N/16 aqueous 

 solutions of ethyl barium sulphate were measured at 60° C, 

 and the conductivities of intermediate concentrations were 

 determined by Kohlrausch's method of graphic extrapolation. 

 The equivalent conductivity of the salt at extreme dilution was 

 found from the velocities of its ions at 25° C* and the tem- 

 perature coefficient calculated from conductivity measurements 

 made at 25° C. and 60° C. The conductivities of different 

 concentrations of hydrochloric acid at 60° C. were calculated 

 from the values of Kolhrausclrf at 18° C. and the temperature 

 coefficients of Holborn.;}; From these conductivity values the 

 values of d, and d 2 in Table II were found. For calculating the 

 constants K„ and K 3 the mean values d l and d 2 given in the 

 corresponding series of Table II for the time intervals t to t a 

 were used, since the total changes in d l and d, 2 during the 

 course of the. reaction are small.
