Summary

Joseph Henry and fellow scientist Lewis C. Beck construct a scale of chemical equivalents under the direction of English chemist William Hyde Wollaston, who published the first such scale in 1814. Henry's and Beck's scale is said be "nearly twice the length of Wollaston's" with "the names of more than double the substances," and to be far more precise. Its formal publication date is September 1827. In 1846, Henry would become the first Secretary of the Smithsonian Institution.
