Until the recent discovery of the Codex Sinaiticus by Tischendorf, the first four and a half chapters were known only in an ancient Latin version. The whole Greek text is now happily recovered, though it is in many places very corrupt. We have compared its readings throughout, and noted the principal variations from the text represented in our version. We have also made frequent reference to the text adopted by Hilgenfeld in his recent edition of the Epistle (Lipsiae, T. O. Weigel, 1866).
