Some years ago Dr. W. W. Greg in an article, “Bibliography—An Apologia”, ably presented the aims and scope of analytical bibliography. Among the phases of that science which he treated at some length was critical bibliography, the study of the transmission of texts. As a bibliographer he emphasized the value of the critical or bibliographical approach, “the humble collation of textual variations and reconstruction of scribal steps”, as contrasted to the metacritical, the intuitional and personal selection of the best or most authentic. Although Dr. Greg's concept applies to the transmission of all texts, I am limiting my study, for the sake of illustration, to a particular case.
