An examination, some time since, of scattered notes on allusions to Cain in our literature showed that there was still room for a somewhat more thorough investigation of the subject. The results of such leisure as could be given from time to time are here presented. They cover, it is hoped, the main features of the Cain story, though not unlikely some allusions have been missed. Many more references might also be given to notes on various phases of the subject, but I have preferred not to overload the footnotes with comparatively unimportant ones. In general I have intended to give the more important, preferring earlier to later, and original to derived sources when possible. Lack of time to pursue the matter further at present is the excuse for publishing the paper in this form.
