Notes:
Two imposing related problems confronted the chemical spectroscopist of the late nineteenth century. First, he lacked a criterion for judging the validity of claims for elemental discoveries; indeed, he possessed no satisfactory operational definition of the chemical element. Secondly, he felt the need for correlating the spectra of the elements to a conception of their ultimate constitution.
