Abstract
THE first step towards my present views as to the evolutions of the various groups of cosmical bodies was taken when one day I was attempting to trace the origin of the absorption flutings in stars of Vogel's Class III.α. So far, no one had endeavoured to trace their origin, all the work having been confined to the absorption lines. It is true that both Dr. Huggins and Vogel, as well as others, had published maps of the spectra of these stars, showing the absorption flutings as well as the lines, but the origins of the former were not inquired into.
