Mr. Chalmers lays stress on the influence of Queen Margaret’s marriage to James IV. as probably having produced some of the imitations of English perpendicular work found at Melrose and Linlithgow, and this may possibly have been the case. In a review of Vol. II. in the _Glasgow Herald_ attention was drawn to an error in the description of St. Andrews Cathedral (p. 31), where the restored illustration (Fig. 453) shows a single central shaft in the windows of the chapter house, instead of two coupled shafts. The shafts are gone, but the two bases are still traceable. * * * * * We have to thank the numerous clergymen, proprietors, custodians, and others, to whom it has been necessary to apply for permission to visit the various churches, for their assistance, which was always freely given. Our acknowledgments are also due to those gentlemen who have kindly continued their contributions to our work in the form of drawings and descriptions of churches, especially to Mr. T. S. Robertson, Dundee, and Mr. William Galloway, Whithorn. Mr. R. Weir Schultz, London; Mr. John W. Small, Stirling; Mr. F. R. Coles, Edinburgh, and others have also been good enough to furnish us with several drawings and descriptions for this Volume, as is noted in the text. To the Librarians of the Advocates’ Library and the University Library of Edinburgh, and the Keeper of the National Museum of the Antiquaries of Scotland, we are greatly indebted for their valuable assistance. We desire, further, to express our obligation to Mr. Alexander Ross, architect, Inverness, and Mr. R. Bruce Armstrong, for permission to use illustrations from their published works; and to Mr. W. Rae Macdonald, Edinburgh, and Mr. R. C. Walker, Dundee, for their aid in connection with the heraldry of the buildings and monuments. EDINBURGH, _October 1897_. CONTENTS. PAGE
