1. Text. It was proposed at first to make the translation from the text of Herding. This, and all editions, gave so little basis for scientific certainty in regard to various readings that a cursory examination of mss. was made. At the suggestion of Professor O. von Gebhardt of Berlin the examination was made as thorough and systematic as possible with definite reference to a new edition. The translator hoped to finish and publish the new text before the translation was needed for this series, but classification of the mss. proved unexpectedly intricate and the question of the Greek translation so difficult that publication has been delayed. The material has however been gathered, analyzed, sifted and arranged sufficiently to give reasonable certainty as to the body of the work and a tolerably reliable judgment on most of the important variations.
