This MS., came into the possession of the Rev. John Jamieson, D.D., probably long before the publication of his Etymological Dictionary in 1808, where he mentions his having two MSS. of Knox's History, (this, and the one marked No. VIII.) in his list of authorities; but neither of them was known, and consequently had never been examined by Dr. M'Crie. At the sale of Dr. Jamieson's library in 1839, both MSS. were purchased by the Editor. In the firm persuasion that this MS. must have been written not only during the Reformer's life, but under his immediate inspection, and that all the existing copies were derived from it, more or less directly, I should have held it a most unprofitable labour to have collated the other MSS., for no other purpose than to notice the endless variations, omissions, and mistakes of later transcribers. The reader may think I have paid too much regard in this respect to the various readings or errors in Vautrollier's suppressed edition, and in the Glasgow Manuscript; but these copies being the only ones referable to the sixteenth century, are deserving of greater attention than those of a more recent age, while the variations pointed out frequently serve to account for the mistakes in the later transcripts. But before explaining the manner in which this edition has been printed, it may be proper to enumerate the other Manuscripts which are known to be preserved; and I may take this opportunity of expressing to the several Proprietors my grateful acknowledgments for the free use of the copies specified. II.--VAUTR. EDIT.--PRINTED AT LONDON IN 1586 OR 1587. This edition, described at page xxxix, is here introduced as representing an intermediate MS., from which some of the existing copies were apparently derived. Thomas Vautrollier the printer, a native of France, came to England in the beginning of Queen Elizabeth's reign. He retired to Scotland in the year 1584, and printed several works at Edinburgh in that and the following year. In 1586, he returned to London, carrying with him a manuscript copy of Knox's History, which he put to press; but all the copies were seized before the work was completed. The manuscript copy which he had obtained is not known to be preserved; but there is no reason to doubt that it was taken directly from the MS. of 1566. This appears from the marginal notes and a variety of minute coincidences, perceptible on collating the printed portion. We may likewise conclude, that from it several of the later transcripts were taken of the introductory portion, and the Fourth Book, to complete the text of the unfinished printed volume. III. MS. G.--IN THE UNIVERSITY LIBRARY, GLASGOW. In folio, containing 242 leaves, written before the end of the sixteenth century. This MS. was long considered to be the earliest and most authentic copy of the History, and consequently no small degree of importance was attached to it.
