XIV. On the spectrum of the flame of hydrogen

Abstract

Messrs. Liveing and Dewar state, in a paper read before the Royal Society on June 10 ( ante p. 494 ), that they have obtained a photograph of the ultra-violet part of the spectrum of coal gas burning in oxygen, and in a note dated June 8 they add that they have reason to believe that this remarkable spectrum is not due to any carbon compound but to water. Under these circumstances I think that it is desirable that I should give an account of some experiments which I made on this subject some months since without waiting until the investigation is more complete.
