Apparatus — a U-tube into both arms of which were dipped 

 tubes closed at the lower end with parchment forming the anode 

 and cathode compartments respectively, in the U-tube were 

 plugs of cotton batting; Pt. electrodes; no middle portion. 



The results are only qualitative, and show that in a solution 

 of FeFl3.3NaFl + iHjO containing 0.8 mg iron in i c.c. the 

 iron moves toward the anode, presumably in the form of FeFlg"'. 

 In the case of an equivalent solution of Fe2(SOj3 under the same 

 conditions the difference in titration value of a constant weight 

 of solution before and after electrolysis was three times as great ; 

 here the iron moved towards the cathode.
