An examination of some methods employed in determining the atomic weight of Cadmium

"An Examination of Some Methods Employed in Determining the Atomic Weight of Cadmium" by John E. Bucher is a scientific study from 1894 that looks closely at different ways scientists tried to find the atomic weight of cadmium, revealing how their results often differed. It's a report of experiments and a story of how scientists worked to get more exact measurements in chemistry. Bucher writes about several methods, like using oxalate, sulphide, chloride, bromide, and oxide, explaining exactly how each one was done, what was needed, and how the atomic weight was figured out. He also points out where mistakes could happen in each method, mainly because of unclean materials or reactions that didn't finish completely. He suggests an average atomic weight for cadmium of about 112.38, but makes it clear that this isn't perfect, showing the difficulties of doing chemical analysis back then.
