Forrer (editor of _Antiqua_), and others, as well as a large number of the secretaries of Archæological Societies, have most cordially granted me permission to take extracts or copy such illustrations from their published works as I might think necessary. The instances in which I have availed myself of this privilege are acknowledged in the text and in the tabulated list of illustrations. (4) The following Societies have kindly allowed me to use electrotypes of a number of their woodcuts, all of which are duly specified in the list of illustrations:-- Ayr and Galloway Archæological Association. Society of Antiquaries of Scotland. Anthropological Society, London. Royal Archæological Institute of Great Britain and Ireland. Royal Irish Academy. Royal Historical and Archæological Association of Ireland. (5) The bibliography was to a large extent compiled at the British Museum Library, where I found greater facilities for such work than in any similar institution on the Continent. In addition to ready access to public libraries, I have to acknowledge the receipt of a number of valuable annotations and references in special libraries attached to museums or belonging to Societies. Among the archæologists who have thus aided me I have specially to mention MM. PIGORINI, VOSS, and REINACH (St. Germain). The Hon. H. A. Dillon, Secretary of the Society of Antiquaries, supplied me with the reference to the capture of an Irish crannog by the English, quoted at page 482. My learned friend Joseph Anderson, LL.D., greatly assisted me in revising the proof sheets. For all these varied and valuable contributions to this work, as well as for the many acts of kindness and good wishes received during our peregrinations, I now express my warmest thanks and gratitude. _Edinburgh, 15th May, 1890._ CONTENTS.
