On Dispersion and Spectrum Series

IN reply to Mr. Campbell's letter of April 30, it must suffice to point out that my letter of March 5 was limited to infinite spectrum series and to luminous gases. This seemed to me at the time of writing obvious from the context, as well as from the express reference to the finiteness of the refractive index of luminous hydrogen. Apparently I was mistaken; anyhow, Mr. Campbell's suggestion that I confused the emission lines of luminous with the absorption bands of dark hydrogen rests on a misconception of my meaning.
