Abstract
WHILE examining the spectra obtained by passing varying discharges through the vapour of pure metallic arsenic contained in capillary tubes, certain lines were found to be even more strongly enhanced than those due to the trebly-ionised atom, with increase in the intensity of excitation. A strong doublet at λλ 2902, 2785 which was completely suppressed by the introduction of the slightest inductance in the circuit was therefore ascribed to the quadruply-ionisod atom of arsenic.
