For one who has learnt the best of what he knows within Christ Church walls it has been very pleasant to gather these notes of the Cathedral's history and architecture. Moreover, I am less remorseful than I might be at adding to the world's overcrowded library, because certain recent discoveries in the Cathedral have thrown the best of the old books out of date, and made it necessary for some one to weave together the older and the later knowledge. My indebtedness, therefore, is not only to former labourers in this field, but especially to the author of these discoveries, Mr J. Park Harrison, who roused my enthusiasm in the old days, and now has most generously helped me with his advice, and allowed me to incorporate in these chapters the substance of his own papers. To these pamphlets I would refer any who wish to go to the fountainhead for the account of the investigations, and especially I may mention two: "The Pre-Norman Date of the Choir and some of the Stone-work of Oxford Cathedral," and the "Account of the Discovery of the Remains of three Apses at Oxford Cathedral" (Oxford: Frowde, 24 and 23 pp.). I must also express my thanks for the kindness and help of Professor York Powell, and of Mr W. Francis, the senior verger, and to Messrs Carl Norman & Co. of Tunbridge Wells, Mr W. Giles, Mr Park Harrison, and Mr R. PhenÉ Spiers, F.R.I.B.A., for the loan of and permission to reproduce various drawings and photographs.

PERCY DEARMER.
