I wish to thank Mr. Robert Ross, Wilde's literary executor, Who has helped me in every possible way, allowed me to read many of the letters that Wilde addressed to him, and given much time out of a very busy life to the verification, from documents in his possession, of the biographical facts included in my book. I wish to thank Mr. Walter Ledger for much interesting information, and for the sight of many rare editions of Wilde's books that made possible the correction of several bibliographical errors into which I had fallen. I wish to thank Mr. Martin Seeker for putting at my disposal his collection of late nineteenth-century literature. I wish to thank an anonymous author for lend ing me the proof-sheets of a forthcoming book, which will contain a full and accurate account of the legal proceedings for and against Wilde. Many of those who knew Wilde have helped me, by letter or in conversation, with valu able reminiscence. I would thank, particularly.
