The very great obligations I am under to Lieutenant F. W. L. Thomas, R.N., are repeatedly noticed in the following pages, though in no degree adequately to the generosity with which the knowledge acquired by him during his professional exploration of the Orkney Islands, while engaged in the Admiralty Survey, has been placed at my disposal. I have also to acknowledge the contribution of valuable information from my friend Professor Munch of Christiania, and from George Petrie, Esq. of Kirkwall; as well as kind services rendered me in various ways by Charles Roach Smith, Esq., J. C. Brown, Esq., William Nelson, Esq., by my indefatigable friend and correspondent, John Buchanan, Esq. of Glasgow, and others referred to in the course of the work. My special thanks are due to Robert Hunter, of Hunterston, Esq., for his courteous liberality in forwarding to me the valuable Scottish relic found on his estate--engraved as the frontispiece to this volume--after I had despaired of making anything of its remarkable Runic inscription from various copies obligingly furnished. Whatever opinion may be formed as to the value of the interpretation of its inscription offered here, the archæologist and philologist may both place the utmost reliance on the fidelity of the engraved fac-simile of this interesting monument of the palæography, and, as I believe also, of the language of our ancestors. Besides putting into the engraver's hands a carefully executed drawing, he had the advantage of having the brooch itself before him while engraving it; after which I went over the copy in his presence, comparing it letter by letter, and checking the minutest deviations from the original. It is justly remarked in the "Guide to Northern Archæology," that "in copying Runic inscriptions great accuracy is required; for a point, a small, scarcely perceptible line, changes the value of the letter, or occasionally adds a letter, which may easily escape notice." When, however, it is added that "one of the best helps in copying Runic, and indeed all other inscriptions, is a knowledge of the language in which they are written," I am inclined to question its strict justice. Most authors, I believe, who have had any experience of the matter, would much prefer a compositor entirely ignorant of the language for setting up Latin, or any foreign tongue, at least to one short of being a perfect master of it. Where there is the total absence of knowledge of it, the imagination is entirely at rest; and the patient copying of letter after letter ensures the accuracy which often surprises the young author when revising his first proofs. Even so I would, in most cases, place more faith in the version of an inscription by an engraver accustomed to accurate copying, though entirely ignorant of the language, than in that of the ablest philologist, with his head full of speculations as to its meaning. A direct example in point is found
