28, 971, and Zeit. f. Elektrochem., //, 109). Apparently two 

 methods were used, both being meniscus-velocity methods. 

 The simultaneous measurement of the velocities of the anion 

 and cation succeeded only in the case of NH^NOg. The other 

 measurements were made in a complex " sehr sinnig ausge- 

 dachtem " apparatus, and the migration values were deduced 

 with the help of conductivity measurements. The indicators 

 used were Hg-, Pb-, Cu- and Bi-salts at the anode, and picric 

 acid at the cathode. The concentrations lay mostly between 

 0.5 and o.oi m ; temperature — 34°C. In NH^Cl and NH^Br 

 the migration value increases rapidly with the concentration.

 the results are incorrectly calculated (based on volume of solu- 

 tion, not amount of solvent). In the last column below is given 

 the solvent ; the authors do not mention whether the mixtures 

 were made by weight or by volume.
