Although increased leisure, gained more than two years ago, by release from the public duties of the Edinburgh lecture-room, may have hardly compensated for abatement of strength in the evening of life, I have gladly devoted a portion of that strength to this labour of love in connexion with Locke; in succession to the development of the philosophy of Berkeley in which I was before engaged. In each undertaking I have been encouraged by the countenance of the illustrious University, associated with the historic memories of many centuries, which has not forgotten that Oxford was the academic home of Locke, and the chosen retreat of the old age of Berkeley. I desire in particular to thank the Delegates, the Secretaries, and the other officials of the Clarendon Press for their kindness, in the course of those critical reconstructions of Berkeley and Locke, during the last twenty-five years. I am indebted to Professor Andrew Seth, my distinguished successor in the University of Edinburgh, for reading the proofs of the greater part of the present work, and for valuable suggestions. In the preparation of the Index I have had the able assistance of Mr. Henry Barker. GORTON HOUSE, Hawthornden, Mid-LothIAN : February 9, 1894. A. C. F. (B.) CRITICAL. XIV.
