Abstract

IN the letter which appears in NATURE of Jan. 3, p. 10, Lord Rayleigh discusses the excitation of the green fluorescence of mercury vapour by wave-lengths near the resonance line γ2537. The discontinuity of intensity of the fluorescent radiation along the beam of the exciting light leads him to admit the atomic as well as the molecular absorption. The hypothesis of two kinds of absorption exciting the fluorescence was further confirmed by Lord Rayleigh's investigation of the influence of the hydrogen admixture. These experiments support the view that the fluorescence of mercury vapour is chiefly due to atomic absorption.
