Vogels, in his new “Handbook to New Testament Criticism,” has started some interesting and important enquiries, by a consideration of the changes that can be marked in the copies and versions of the New Testament by an investigator who understands not only how to register various readings but also how to detect the causes of such differences.

The people who handle the text leave their finger-prints on the pages, and the trained detective can identify the criminal who made the marks.
