For valuable work in the British Museum Library extending over a considerable length of time I have to thank Mrs. Pearde Beaufort, Miss C. J. Hamilton, and Miss G. B. Ryan. For much tedious labour in the rearrangement of the matter contained in the earlier book, I am indebted to the Misses Chenevix Trench (who also supplied many notes), and to Mrs. O’Neill, of Dundalk. To Dr. Crone, whose readiness to help when any Irish literary enterprise is afoot is inexhaustible, I owe many corrections, suggestions, and additions, and the laborious task of revising my MS. and correcting my proofs. Mr. Edmund Downey, of Waterford, has kindly read part of the proofs. Many books have been read for me and notes supplied by Lady Gilbert; Mrs. Concannon, of Galway; Mrs. L. M. Stacpoole Kenny, of Limerick; Miss J. F. Walsh, of Derry; Miss R. Young, of Galgorm Castle, Co. Antrim; Mrs. Macken, of the National University; Fr. MacDwyer, of Killybegs; and, perhaps most of all, Fr. J. Rabbitte, S.J., of St. Ignatius College, Galway. Mr. D. J. O’Donoghue, Librarian of the National University, has given me many suggestions, as well as some useful notes on fiction in Irish periodicals. Mr. Frank Macdonagh also has been very helpful with notes and corrections. I owe likewise a debt of gratitude to the authorities and the staff of the National Library for their courtesy and helpfulness. Nor must I omit a word of thanks to the publishers (including all the Irish publishers, and Messrs. Flynn, of Boston), who, as on a former occasion, made my task much lighter by supplying me with review copies of their books. Lastly to all the others, and they are many, who have in various ways given me help my very sincere thanks are hereby tendered. For the matter contained in my notes on the Authors, I am much indebted to Mr. D. J. O’Donoghue’s _Poets of Ireland_, and to the pages of the IRISH BOOK LOVER. [2] Through an unfortunate oversight the earlier work contained no mention of much kind help rendered me by several students of St. Patrick’s College, Maynooth, notably by Rev. J. Henaghan and Rev. J. Pinkman, at present priests on the mission. I now gratefully acknowledge this help. SIGNS, ABBREVIATIONS, ETC.
