Having arranged as to the examples of tartan to appear in the volume, it became necessary to decide on the form of illustration. Hitherto the modes adopted in works of this description have been admittedly unsatisfactory, it being impossible, by the highest exercise of skill in colour printing, to render the shades correctly, particularly in those portions of the setts where the colours are crossed. Solid colours are generally rendered adequately by lithography, but when the most important and intricate portion of the design—viz., the representation of the interweaving of different shades—is in question, none of the processes of colour printing yet invented does justice to the great beauty of the actual fabric. The method adopted in the present work has been to weave the tartan to be represented in its proper colours in fine silk. The shades required for each specimen having been dyed, the weaving was executed by the hand-loom in exact proportion to the original. To ensure permanency the mounting was arranged so that no portion of the silk forming the illustration should come into contact with the adhesive. The second object kept in view in the preparation of the work was to examine and present, in something like chronological order, the references in old writers to tartan and the Highland dress. The only attempt of the kind hitherto made was that by Donald Gregory and W. F. Skene, included in the _Transactions of the Iona Club_. Since that valuable work was published a great deal of interesting and original material has been discovered. But what may be termed the literature of the subject is so widely diffused, and contained in works so difficult of access to the general reader—many of them being in MS., and others rare and costly—that it seemed to be of importance to present these notices in a form which would render easy comparison between different ages and authors. Something of this kind the Editor has endeavoured to carry out in the Introduction. Particular attention has been paid to the accuracy of the extracts, which have been carefully verified by comparison with the authorities. One result has been the discovery of serious errors in quotations by previous writers, and the more important of these are pointed out. The Editor trusts that, considering the importance of the objects he had in view, the length to which several of the extracts have unavoidably run will be pardoned by his readers. He has omitted many references which he regarded as of minor consequence, while several of much importance are given for the first time. There remains the pleasant duty of thanking those by whose aid the Editor has been enabled to produce the work.
