IN a recent letter to NATURE1, Dr. T. L. Page reports on an interpretation of the spectrum of hydrogen in the discharge tube and in the planetary nebulæ. The observed data consist of measures of the intensities, in emission, of various members of the Balmer series and of the continuum that lies beyond the Balmer limit. Page states: ``In the nebulæ and in the discharge it can be shown that the recombination of protons and electrons must account for almost the entire emission.'' He interprets the data on the basis of this assumption. All the quanta of Balmer α, for example, he regards as being produced by electrons that have arrived in quantum level 3 either by direct capture in that level or by cascade from higher levels after capture. He apparently neglects all other types of excitation, such as reabsorption of the Lyman line radiation or collision. Failing to find agreement between the number of captures calculated theoretically from Kramers' well-known absorption law and the number deduced from the observations, Page concludes that Kramers' law is in error. I should prefer another alternative, namely, that the nebular and discharge spectra are not entirely due to recombination.
