This paper is a continuation of the author's investigation into the spectra of mixed gases, and he finds that the same general laws hold good in the present case as before, namely, that the relative intensity of the spectrum of a gas present in a mixture is increased by increasing the relative amount present, that, other things being equal, in a steady discharge the spectrum of that component of a mixture having greater atomic weight will be brighter, and that in a disruptive or forced oscillatory discharge the effect due to atomic weight is less. The amount of electrode vapour present depends upon the current and electrode fall of potential. This electrode-fall is again a function of other variables; it is nearly proportional to the curren
