 Stas atomic weights: teaching notes
Stas did the experiments and published the results; presumably data may be found in his original paper.
Although this also was not correct (in fact, it was further from the truth than Prout's original hypothesis) it inspired accurate determinations such as Stas' and, 25-30 years later, the investigations of Lord Rayleigh that eventually led to the discovery of argon.
Jean Charles de Marignac (1817-1894) was also an analytical chemist and a contemporary of Stas.

Stas measured atomic weights for a number of elements which Dumas thought supported Prout's hypothesis, i.e., nitrogen, chlorine, sulfur, sodium, potassium, silver and lead, in a series of experiments finally published in 186012.
Stas proved that atomic weight values were not multiples of hydrogen, one-half the hydrogen value or even one quarter of the hydrogen value (as was maintained by Dumas).
Following Stas' first paper, he redetermined the atomic weights even more carefully in 186513, after Marignac14 had cast doubt on the law of constant proportion and on the possibility of obtaining chemically pure substances.

Richards greatly improved the technique of gravimetric atomic weight determinations, introducing quartz apparatus, the bottling device, and the nephelometer (an instrument for measuring turbidity).
Although the atomic weight values of Jean Servais Stas had been regarded as standard, about 1903 physicochemical measurements showed that some were not accurate.
Richards and his students revised these figures, lowering, for instance, Stas's value for silver from 107.93 to 107.88.
