It was shown at an early stage of the present workf that the characteristic fluorescence of mercury could be generated by wave-lengths much longer than the resonance line λ 2537; indeed, its excitation was traced as far as λ 3450. It was found also that the primary excitation by atomic absorption (core of the resonance line) could be distinguished from excitation by molecular absorption (wing of the resonance line). Although in the case of the longer waves it appears certain that the excited systems produced in the first instance by absorption are molecules and not atoms, yet it is possible that subsequent dissociation, or excitation by collision might lead to the formation of excited atoms in a secondary way.
