 Table B. 



The result of these experunents with the bromide confirms closely 

 that obtained by Baxter and Hartmann by electrolysis of cadmium 

 chloride, as well as that found by Baxter and Hines by comparing both 

 the chloride and bromide with silver, 112.417 (Ag = 107.880). 



Mr. Grose also completed a series of electrolyses of zinc bromide by 

 methods exactly similar to those used with the cadmium salt. 



Table C. 



This result is an interesting confirmation of that obtained by Rich- 

 ards and Rogers, 65.37 (Ag= 107.880), through the comparison of zinc 

 bromide with silver, and thus lends weight to the value of the electro- 

 lytic method in general.
