and has replied with great minuteness to several questions of mine relating to different works of Blake. My thanks are also due to Miss Isabelle Linnell and Mr. William Linnell.
I owe to the kindness of Mr. C. Fairfax Murray the loan of the autograph MS. known as An Island in the Moon, since presented by him to the Fitzwilliam Museum, as well as extracts from original letters of Flaxman throwing light upon the cause of Blake's estranged attitude towards his former friend. A hitherto unprinted poem (see p. 218) courteously sent me by Mr. A. G. B. Russell illustrates the earlier and happier relationship between the two artists.

I am obliged to Mr. Bernard Quaritch for lending me the MS. of Tiriel. To Signora Helen Rossetti Angeli I tender my thanks for her kindness in sending me from Italy the early and curious Blake MS. containing 'The Passions' and another piece.
I have to acknowledge the courtesy of the various owners of copies of the Songs of Innocence and the Songs of Experience enumerated in my Bibliographical Preface (pp. 72-77), for collations and details of the several impressions.
Mr. W. M. Rossetti kindly furnished me with his recollection of the lost book, the French Revolution, and also of the Pickering MS. which has since come to light. Mr. John Pearson in several communications has given me the benefit of his expert knowledge of original issues and reprints of works of Blake, and Mr. John Lawler has been good enough to supply me with information as to Blake originals sold by auction. Mr. Frederick Macmillan has taken great pains to clear up the question of the process by which the plates of the Songs were reproduced in Gilchrist's Life.
I am indebted to Mrs. Beach for research work in the British Museum in the early stages of this book. I am grateful to Mr. Cowley of the Bodleian Library for a courteous response to questions submitted by me, in the first place, to Mr. Madan; to Mr. Fortescue of the British
