In recent years the class of spectrum lines known generally as the enhanced lines has become of especial importance in connection with their bearing on modern views as to the constitution of the atom. These lines were first investigation by Sir J. N. Lockyer, whose classical researches in this field have shown that a high order of energy is required for their production, and that they are especially conspicuous in many stellar spectra. An important paper has recently been published by Fowler, who has shown that the enhanced lines of the elements of the alkaline earth group can be arranged in series similar to those obtained in are spectra, but that for these series Rydberg’s constant N has to be replaced by the value 4N.
