Last year, also, a translation into French appeared by M. le Pro- fesseur F. Nau, of the Catholic College in Paris, published seriatim in the Canoniste Contemporain, and now republished in a separate form. I have compared M. Nau's translation with my own, and in very few points indeed have I ventured to differ from him. His accuracy and penetration are beyond praise. I desire once more to thank him for his collation of Codex Borgia ; and my gratitude is due also to Monseigneur Graffm for the photographs of that MS.; to Dr Eberhard Nestle of Maulbronn, and to my sister, Mrs Lewis, for their assistance in the revision of my proofs ; and to the readers and printers of the University Press, for the care with which they have executed their troublesome work.
