In a former communication* an account was given of an investigation on the analysis of the Spark Spectra of Germanium (Ge II, Ge III, Ge IV) made by the writer in collaboration with Prof. A. L. Narayan. The present paper is an attempt at the elucidation of the arc spectrum of germanium. The investigation of this spectrum made up to 1912 are summarised in Kayser’s ‘Handbuch,’ vol. 5. With the aid of the existing measures and the recurring frequency differences pointed out by Paulson, McLennan and McLay have indicated a few combination arising from the deep terms of Ge I. Richter has measured the arc spectrum to λ 2417 with a 6-meter concave grating and arrived at some of the groups identified by McLennan and McLay. The most important contribution is that of Gartlein§ who has extended the spectrum to λ 1873 and classified most of these lines.
