" The Eesistance of the Ions and the Mechanical Friction of the 

 Solvent." By Friedr. Kohlrausch, Foreign Member K.S. 

 Eeceived February 17, — Read March 5, 1903. 



(Translated into English for Dr. Kolilrausch by Dr. L. Aixstin.) 



Messrs. Bousfield and Lowry in their interesting paper, " The 

 Influence of Temperature on the Conductivity of Electrolytic 

 Solutions,"* have discussed a hypothesis recently advanced by me. In 

 this I stated the probability that the conductivities of all aqueous 

 solutions approach, with decreasing temperature, a zero value at about 

 the same temperature, and that the cause of this phenomenon is to be 

 looked for in the disappearance of the fluidity of water. This hypothesis 

 was very briefly mentioned, as it were, in parenthesis, in the midst of 

 the discussion of the numerical data which formed the main portion 

 of the paper.f
