Series V.* 



The comparison of Series II and IV with respect to temperature 

 control and of III and IV with respect to dilution of cell contents was, 

 on the whole, unsatisfactory. There was to be found in the results 

 no evidence of any progress in the improvement of devices for the 

 regulation of the baths, and the reduction of dilution, from 1.73 per 

 cent in Series III to 1.41 per cent in Series IV, did not betoken an 

 early suppression of all dilution. It was evident that, in order to
