1. This paper deals with the continuation of our endeavour to arrange the lines of this spectrum in series by starting from a study of the lines which are selectively changed in intensity in electron discharges in hydrogen at a low pressure as compared with discharges in a Geissler tube of the type which is most usual in spectroscopic observations. The previous work has been described in two papers which we shall assume to be available in dealing with what follows. 2.A Second P, Q, R Combination .—We commence by considering the following lines which can be arranged as P, Q, and R series with the enumeration shown.
