The Bromide method.
Huntington (Proc. Amer. Acad. 11.28) working under the direction of J. P. Cooke, determined the ratio of cadmium bromide to silver bromide and using the total quantities for the calculation the result for the atomic weight of cadmium is 112.239. He also determined the ratio of cadmium bromide to silver, obtaining 112.245 for the atomic weight of cadmium.
The work which will now be described was carried out very much like the work described under the chloride method. The ratio of cadmium bromide to silver bromide was investigated.
