British Museum, but has read the proofs of Chapter V. Mr. H. Yule-Oldham in Chapter XVIII. on the Voyage of Cadamosto, and Mr. Prestage in Chapters VIII. and IX. on Prince Henry's capture of Ceuta and settlement at Sagres, have been most kind in offering suggestions. For several hints useful in Chapter I.—the early Christian pilgrims—I have also to thank Professor Sanday; and for revision of a great part of the proof-sheets of the entire book, Mr. G.N. Richardson and the Rev. W.H. Hutton.

As to the illustrations, of portraits and monuments, etc., I am especially obliged to the Vice-Chancellor of Oxford University (Dr. Boyd), who has allowed his water-colour paintings of Portuguese subjects to be reproduced; and to the Rev. R. Livingstone of Pembroke, and Sir John Hawkins of Oriel, for their loan of photographs.[Pg xxviii]
