My larger debt, however, is to my valued collaborator, Capt. B. M. Ward, who has written an introduction to this book, and. From whose Life of Me Earl of Oxford I have, with his consent, and with that of Messrs. John Murray, his publishers — to whom also I express my indebtedness — taken substantially all the facts, extracts from correspondence, and so forth, which make up the biographical basis of this work. For reasons of space and economy, I have not inserted, in the following pages, the usual page-references to Capt. Ward's volume, which my own does not supersede; since I have, in the main, used extracts only, from the letters and other documents quoted, which, with much other information, can be read.
