By the courtesy of the Corporation of Nottingham I am reproducing a clock in their collection, and similarly by the courtesy of the Bristol Corporation I am including an example in their possession. The Corporation of Glasgow have afforded me permission to include a remarkable example of Scottish work, and the authorities of the Metropolitan Museum, New York, have accorded me a similar privilege in illustrating specimens in their collection. Among those who have generously augmented my researches and come to my aid in regard to local makers, I desire to express my obligation to George H. Hewitt, Esq., J.P., of Liverpool, who arranged the clocks in the exhibit at the Liverpool Tercentenary Exhibition in 1907, and to E. Rimbault Dibdin, Esq., of the Walker Art Gallery, Liverpool. To Basil Anderton, Esq., of the Public Libraries, Newcastle-upon-Tyne, and to T. Leo Reid, Esq., of Newcastle-upon-Tyne, I am especially grateful for solid help in regard to North Country makers. To H. Tapley-Soper, Esq., City Librarian, Exeter, I am indebted for names of West-Country makers, and to A. Bromley Sanders, Esq., of Exeter, I am obliged for information relating to local clocks coming under his purview for many years. James Davies, Esq., of Chester, and S. H. Hamer, Esq., of Halifax, have enlarged my horizon in regard to local makers. H. Wingent, Esq., of Rochester, an enthusiastic collector and connoisseur of old clocks, has kindly enabled me to reproduce one of his examples. To Herbert Bolton, Esq., of the Bristol Museum and Art Gallery, I am indebted for the inclusion of a fine specimen in that collection. I desire especially to record the generous aid I have had from Percy Webster, Esq., of Great Portland Street, London, who is well known as a connoisseur of old clocks, and from his son, Malcolm R. Webster, Esq., who have given me practical assistance in regard to verifying facts from actual examples. To Thomas Rennie, Esq., of the Glasgow Art Galleries and Museums, I desire to record thanks. To Edward Campbell, Esq., of Glasgow, who has enriched my volume with examples of Scottish work in his collection, I am indebted for information regarding Scottish makers embodied in this volume. I am, by the kindness of John Smith, Esq., of Edinburgh, author of _Old Scottish Clockmakers_, and of his publisher, William J. Hay, Esq., John Knox's House, Edinburgh, enabled to produce names and dates of certain Scottish makers not recorded elsewhere. In this connection my friend William R. Miller, Esq., of Leith, has spared no time to help me to do justice to Scottish makers, and I am especially grateful to him for his kindly enthusiasm. He was there at the "chap o' the knok" when I asked his help.
