PREFACE.
The text of this edition is a reprint (page for page and line for line) of a copy of the 1820 edition in the British Museum. For convenience of reference line-numbers have been added; but this is the only change, beyond the correction of one or two misprints.
The books to which I am most indebted for the material used in the Introduction and Notes are The Poems of John Keats with an Introduction and Notes by E. de Sélincourt, Life of Keats (English Men of Letters Series) by Sidney Colvin, and Letters of John Keats edited by Sidney Colvin. As a pupil of Dr. de Sélincourt I also owe him special gratitude for his inspiration and direction of my study of Keats, as well as for the constant help which I have received from him in the preparation of this edition.
