For the discussion of those cases in which the ratio #/i’ differs from unity, see 
Zeitschr. fiir ph. Chem. ii. p. 497, 1888. The measurements for LiCl, KCl, NH,Cl, CaCl, 
SrCl,, MgCl,, CuCl,, MgSO,, Ca(NO,),, FeCy,K, have been repeated, and the results 
confirmed by Van’t Hoff and Reicher (Zeitschr. fiir ph. Chem. iii. p. 198). MgSO, and 
the chlorides remain intractable, possibly in the former case on account of the for-
