Abstract
THIS publication contains the results of the study and reduction to wave-lengths of the lines in the flame, arc, and spark spectra of many of the chemical elements. In all, thirty elements are dealt with for the flame spectrum, sixty-six for the arc spectrum, and sixty-eight for the spark spectrum. In general, the region of spectrum discussed extends from about λ 2400 to about λ 7000. The lists of lines given are not overburdened with the great number of extremely weak lines which occur in the spectra of some of the elements, but this exclusion of the weakest lines does not detract from the value of the work.
