The Ecclesiastical Architecture of Ireland; comprising an Essay on the Origin and Uses of the Round Towers of Ireland. By George Petrie, R. H. A., V. P. R. I. A. Among these, I must not omit to mention that most invaluable work to the student of Irish Topography and History, "The General Alphabetical Index to the Townlands and Towns, the Parishes and Baronies of Ireland:" Census, 1861 which was ever in my hands during the progress of the book, and without the help of which, I scarcely know how I should have been able to write it. I have also consulted, and turned to good account, the

various publications of the Ossianic Society, which are full of information on the legends, traditions, and fairy mythology, of Ireland.

On the most ancient forms of the various Irish root-words

and on the corresponding or cognate words in other languages, I have derived my information chiefly from Professor Pictet's admirable work, "Les Origines IndoEuropéennes, ou les Aryas Primitifs:" Zeuss' masterly work, Grammatica Celtica, in which the author quotes in every case from manuscripts of the eighth, or the beginning of the ninth century: Ebel's Celtic Studies; translated by William K. Sullivan, Ph.D., M. R. I. A. : Irish Glosses; a Medieval Tract on Latin Declension; By Whitley Stokes, A. B.; and an Edition, with notes, of Three Ancient Irish Glossaries; By the same accomplished philologist.

Lectures on the Manners and Customs of the Ancient Irish. By Eugene O'Curry, M. R. I. A. Edited, with Introduction, Appendices, &c., by W. K. Sullivan,

Ph. D. Published in 1873.

S the first edition of this book went off very quickly-it was sold in six months-I have thought it right to issue a second edition with as little delay as possible.

I have considerably enlarged the book, partly by the expansion of some of the articles, which want of space obliged me to curtail in the first edition, and partly by the insertion of additional names.

For the favourable reception of the work by the Press, in England and Scotland as well as in Ireland, I here offer my thankful acknowledgments. It has been noticed in a great number of newspapers and magazines; and while most of the reviews are elaborate and critical, not one is unfavourable. Several of the writers take exception to some of my state

ments, but in the whole of their criticisms I cannot find one unfriendly or unkind remark.

I have examined with great care the objections of those who question the correctness of some of my conclusions. Many of them are palpably wrong; while others, carrying more weight, and requiring more investigation than I can now afford time for, are held over for further consideration. Although I adopted every available precaution to ensure correctness, yet where such a vast number of names and places were concerned, complete freedom from error was a thing scarcely to be hoped for; accordingly a few undoubted mistakes have been detected and pointed out, some publicly by the reviewers, and some privately by my literary friends. These I have corrected in the present edition.

Soon after the appearance of the book, I received communications from correspondents in various parts of Ireland, containing information, more or less valuable, on the topography of their respective localities. Among these I may mention specially Mr. John Fleming, of Rathgormuck in the county Waterford, who has brought his knowledge of Irish to bear in elucidating the topography of the Cummeragh mountains, and who has communicated to me without stint, the results of his investigations. Mr. O'Looney of the Catholic University also furnished me with a large quantity of valuable topographical notes taken

from the Irish Lives of several of our early saints. To these, and to all others who gave me their aid, I return my best thanks. At the same time I take this opportunity of soliciting further information from those who are able to give it, and who are anxious to assist in the advancement of Irish literature.

The head-pieces have been copied by permission— with some modifications in the arrangement-from the marginal illuminations in "The Cromlech of Howth," a work in which are faithfully reproduced the beautiful ornamental designs of the Book of Kells, and other very ancient Irish manuscripts. I have to thank the Council of the Irish Archæological Society for the use of four of their ornamental letters, which were likewise copied from the Book of Kells.
