PREFACE TO THE SECOND EDITION.
The FIRST EDITION of this work has been very favourably received both by the critics and by the public. It was exhausted nearly twelve months ago; but other engrossing occupations left the author little time to revise the text and prepare a new edition. In this SECOND EDITION many errors of the press have been corrected; several explanatory notes have been added, and some few inaccuracies have been rectified. Maps of the Aran Islands and Clonmacnoise have been inserted, and the Index has been greatly enlarged. It is hoped also, that the lower price of the present edition will bring it within the range of a wider circle of readers, and still further carry out the author's purpose of vindicating and enlarging the just renown of Ireland's ancient Saints and Scholars.
