Tin. The Employment Sfl a Diaphragm. 16y HENRY JULIUS SALOMON S S N D . Appczmtus.--The apparatus employed in t,he first part of this investigation (Trans., 1907, 91, 374) has been modified only very slightly. The tripod has been normdly placed on a fsw flat, wooden blocks or plates, so that when desired the beaker may bo lowered relatively to the electrodes by removing the blocks. This is important when large quantities of liquid, such as thme employed in the deposition of tin after removal of

The frame of both is made entirely of iridioplatinum, and the outer has been designed so t h a t it may be held in as narrow a vessel as possible. It will pass through an opening of 34 mm. The stem of the iimer electrode has been lengthened to 16 cm., and is not contracted at, the top. The weights of the electrodes are 34.5 and 27.5 grrtms respectively. The chuck, B (Fig. 4,
