Apparatus U-shaped, consisting of two vertical tubes con- 

 nected underneath by a narrow tube with a glass tap in the 

 middle ; Ag electrodes surrounded with cotton. The author 

 showed by qualitative experiments that Agl moves toward the 

 cathode, probably as component of a complex cation, in solu- 

 tions of Ag3l(N03)2 containing from o.2g Agl in lo c.c. up to 

 saturation (the latter at 70° C).

The author measured the E.M.F.'s of three types of concen- 

 tration cell ; in each, electrodes of the same material were im- 

 mersed in two solutions of sulphuric acid, which were connected 

 by a siphon ; the three kinds of electrodes used were Pb, Hj and 

 PbOj. The migration value was calculated from the formulae 

 for the E.M.F.'s of each two sorts ; the headings of the columns 

 below indicate which two were used as the basis of calculation.
