The authors describe the apparatus used by them in their research and their plan of mapping the absorption spectra, the results being given in wave-lengths. The source of light for obtaining a continuous spectrum was the incandescent positive pole of an electric light, the electricity being generated by ah M. Gramme machine. The light was passed through tubes containing the fluid, and the absorption spectra photographed in the infra-red region.
