Table V gives the p.d. across the membrane at the beginning of the 

 experiments represented in Fig. 3 and Table VI gives the diffusion 

 potentials between the same salt solutions of pH 11.0 against 

 KOH of pH 11,0 without salts and with no membrane between them.

Fig. 3. Transport curves at pH 11.0. Notice reversal of relative efficiency 

 of anions and cations between the curves in Figs. 1 and 3, due to the fact that 

 the sign of charge of liquid inside the pores is positive at pH 3.0 and negative 

 atpH 11.0.
