The Translation of S. Ambrose’s Epistles was made in the early days of the Library of the Fathers by a friend, now with God, before the check which the Series received through various sorrowful losses. It has now been revised by an accomplished scholar, the Rev. H. Walford, M.A., one of the Masters at Hayleybury. Over-work prevented the writing of some introductory remarks. E. B. P.
