To those who, as already mentioned, have aided in the work by reading books, and supplying information about them, my sincerest thanks are hereby tendered. I should be glad, if it were possible, to express here my obligations to each individually, but I must, for obvious reasons, limit myself to this general acknowledgment. There are, however, some whom, on account of special obligations on my part, I shall have the pleasant task of thanking by name. To Mr. E. A. Baker, M.A., D.LITT., Librarian of the Woolwich Public Library, I am indebted both for kind permission to quote from his books and for constant advice and suggestion given with the greatest cordiality. To Dr. Conor Maguire, of Claremorris, I owe most of my notes of books on Irish Folk-lore, and to Mr. Edmund Downey, the well-known author and publisher, notes on Lever’s books, together with many useful suggestions. Mr. Francis J. Bigger, M.R.I.A., of Belfast, the always ready and enthusiastic helper of every Irish enterprise, has aided me with valuable advice and no less valuable encouragement. Mr. J. P. Whelan, Librarian of the Kevin Street Public Library, Dublin, has rendered me every assistance in his power. Dr. J. S. Crone of London, Editor of the _Irish Book Lover_, has on several occasions kindly opened to me the pages of his periodical. Lastly, I must acknowledge here, with sincere thanks, much help of various kinds given me by many members of my own Order, and notably, Rev. M. Russell, S.J.; Rev. M. Corbett, S.J.; Rev. P. J. Connolly, S.J., and the Rev. J. F. X. O’Brien, S.J.—the last of whom very kindly undertook the tedious labour of revising my proofs.[2] [_Additional (Present Work)._] My obligations to my various kind helpers in the present work are even greater than in the case of the former book, and I am at a loss for an adequate expression of them. My thanks have, of course, been privately conveyed, but there are some collaborators who have had so large a share in the making of this book that I cannot but place on record its indebtedness towards them.
