PROF. A. FOWLER has recently shown that the spectrum of Si+ is similar in constitution to that of Al, that is, consists of doublets having 2p2, 2p1, as the highest terms. A number of lines, ascribed by Fowler to Si+, remain, however, well outside his scheme of classification, and some of these can be arranged in a group of quartets.
