In 1902 Jones 1 showed that certain salts have abnormally high molecular weights 

 in acetone solutions, although the same solutions conduct the electric current to a 

 considerable extent. He pointed out the fact that this is not inconsistent with 

 Arrhenius's theory of electrolytic dissociation, since it is quite conceivable that asso- 

 ciation and dissociation may occur in the same solution. It may be remarked that 

 this is known to be the case, for instance, with many homogeneous liquids, such as 

 water. The salts examined by Jones and found to have molecular weights above 

 the normal, were cadmium iodide and ammonium sulphocyanate, both of which 

 Dutoit and Friderich 2 had previously described as having normal molecular weights 

 in acetone. If the above-noted abnormal conductivities are to be explained by 

 assuming association of the electrolyte, it should be possible, by attaining sufficiently
