(Communicated at the meeting of February 24, 1923.) 



In nij book "Die Theorie der Allotropie" '), and also in tlie 

 preceding communications I have treated the electrical supertension 

 only very briefly. Therefore I will discuss this important phenomenon 

 somewhat more at length here. 



We imagine the case that a palladium or |)latinnm electrode is 

 made cathode. For the explanation of the phenomenon that will now

appear, we shall make use of the ^, A'-diagram, in which the ex- 

 perimental electric potential of the electrodes is plotted as function
