Museum for personal replies to like inquiries; and to Mr. Peter Cowell of the Liverpool Public Library for obtaining for me the loan of certain rare books. To Mr. Wilberforce Eames I owe information regarding the unique example of Blake's Milton in the Astor-Lenox Library.
I have pleasure in acknowledging the help of Mr. T. Harkness Graham, assistant in the University Library, in the reading and correction of the proofs, and the aid in various ways given me by Miss May Allen, Librarian to the Biological Library. The help rendered by the members of my class in bibliography, especially by Miss M. E. Lyster and Miss D. E. Yates, has contributed greatly to the accuracy of this edition.
Professor John Macdonald Mackay has been good enough to read certain of my proofs and prefaces.
In concluding this long list of obligations I desire to add that it was at the suggestion of the late Professor York Powell that I undertook, in a somewhat light-hearted mood, the preparation of a small edition of Blake's Lyrical Poems for the Clarendon Press. A cursory comparison of existing texts showed me the impossibility of giving a reliable version of Blake, even in the form of selections, without preliminary collation of the original engraved and manuscript sources. This view was accepted by the Delegates of the Press, and the present critical edition undertaken besides the smaller work at first proposed. I wish to thank the authorities of the Press, and especially Mr. H. S. Milford, for the care and patience with which they have carried out the 'minute particulars' of this book. The untimely death of Professor York Powell deprived me of advantages of advice and encouragement, given by him so generously at the outset of my task, and robs me now of much of the pleasure with which I bring to completion this edition of one of his favourite poets, which, imperfect though it be, I am fain to dedicate to his memory.
