The solution to the Shakespeare problem, which it is the purpose of the following pages to unfold, was worked out whilst the Great European War was in progress; and my wish was to give the matter full publicity immediately upon the cessation of hostilities. As this was found to be impracticable, steps had to be taken, both to ensure that the results achieved should not be lost, and also to safeguard what I believed to be my priority of discovery. With these objects, an announcement of the mere fact of the discovery, omitting all details, was made in November 1918 to Sir Frederick Kenyon, Librarian of the British Museum, and he very readily undertook to receive, unofficially, a sealed envelope containing a statement on the subject. As more than a year has passed since the deposition was made, and as no one else has come forward with the same solution, the question of priority is not likely now to arise, and therefore, with the publi cation of the present work, the purpose of the deposited document naturally lapses. My first duty, then, must be to express my deep sense of indebtedness to Sir Frederick Kenyon for the freedom from anxiety that I have enjoyed whilst further developing the argument and carrying through its publication.
