Salvadori 1 found HgCl 2 to be more highly dissociated in 
methyl alcohol according to the boiling point method than in 
aqueous solutions. Beckmann 2 found the reverse to be true in 
ethyl alcoholic solutions. Jones and King 3 calculated the dis¬ 
sociation of KI from their boiling point determinations, to 
be 25.4 per cent, in a 2 per cent, solution and 27.2 per cent, in a 
3 per cent, solution of ethyl alcohol, i. e., the dissociation in¬ 
creases with the concentration. Cohen, 4 from conductivity de¬ 
terminations at 18° C., found the degree of dissociation 
to increase with the dilution, the dissociation being about 80 
per cent, at a dilution of about 1000 liters. This disagreement 
of the dissociation values obtained by these two methods will 
be made more apparent, perhaps, by Table XXXI. The table 
is copied from Woelfer’s paper. The results by the boiling point 
method were obtained by himself, those by the conductivity 
method by Vollmer.
