yet use the phenomena in electrolytes in order to get a better insight 

 into the nature of the electric current in metals. In this respect 

 more may perhaps be expected from researches as those published 

 lately by Riecke ') under the title „Zur Theorie des Galvanismus 

 und der Warme," where relations are sought between the different 

 thermic, galvanic, thermo-magnenc and galvano-magnetic phenomena 

 in bismuth. I. a. Riecke calculates with the aid of certain supposi- 

 tions U and V for bismuth and finds 



£/•— 0,05.10-5 F= 7,21.10-5. 



I intend shortly to publish the results of measurements of the 

 various phenomena in the same plate of bismuth, and to compare 

 those results with Riecke's theory.
