of it will be sound and satisfactory only when the matter, motive, method of presentation, occasion, and surroundings are all clearly understood. In view of this fact it appears unnecessary to offer further justification for the brief discussion, given in the Introduction, of the oration as distinguished from other literary efforts, and of Cicero's life and character, as affecting his oratory; or for the attention paid, in both Introduction and Notes, to the circumstances of delivery and to the subject-matter.
Besides obligation of a more general nature to the critical editions of Cicero's complete works, and to several other of the editions and works mentioned on pp. 356-358, the editor takes pleasure in making acknowledgment of special indebtedness to the editions of the orations by Richter and Eberhard, Halm and Laubmann, and Reid's Pro Archia; and to those of the letters by Tyrrell, Boot, and Schütz. He is also under obligations to Professor John C. Rolfe and Dr. W. K. Clement for help on the proofs; and to Assistant Professor Carl W. Belser for assistance in preparing the Vocabulary.
