In case of cathodic polarisation the metal phase moves from *S 



upwards along- the line SC, but here we see now that the quantity

of the ever increasing curvature of the line SC, which can be even 



a great deal more pronounced than has been drawn here. 



It now follows from the observations that the metal cadmium 

 assumes internal equilibrium pretty rapidly, and in harmony with 

 this is the fact that after the cui-rent had been broken the polarisa- 

 tion had soon entirely vanished. 



It was besides noticed in this investigation that the metal which
