IT has been my intention from the first to take this opportunity of stating that, if I am indebted to any previous work for the central idea of a stolen manuscript, such obligation should be ascribed to a short tale, published some time ago in one of the Christmas numbers—the only story upon the subject which I have read at present.

It was the story of a German student who, having found in the library of his university an old scientific manuscript, by a writer long since dead and forgotten, produced it as his own; and it is so probable that the recollection of this incident became quite unconsciously the germ of the present book that, although the matter is not of general importance, I feel it only fair to mention it here.

I trust, nevertheless, that it is not necessary to insist upon any claim to the average degree of originality; for if the book does not bear the traces of honest and independent work, that is a defect which is scarcely likely to be removed by the most eloquent and argumentative of prefaces.
