In Part I of this communication it was shown that, subject to certain restrictions, the cataphoretic velocity of an insulating cylinder placed broadside on to the applied field should conform to Smoluchowski’s equation U = DXζ/4π

, (1) whereas the assumptions made by Hückel* lead to the result U = DXζ/8π
η
. (2) This conclusion has been investigated by a method depending on the static deflection of a suspended glass fibre, whose diameter is very great compared with the thickness of the electrical double layer. In principle the method derives from that of Billiter, though the modifications and complications introduced in the effect to make it quantitative are so considerable as to render the technique in effect novel.
