The curious legend connected with the birth of this Adopted Son, and the facts relating to his extraordinary career in after life, are derived from the Records of the French Police of the period. In this instance, and in the instances of those other papers in the present collection which deal with foreign incidents and characters, while the facts of each narrative exist in print, the form in which the narrative is cast is of my own devising. If these facts had been readily accessible to readers in general, the papers in question would not have been reprinted. But the scarce and curious books from which my materials are derived, have been long since out of print, and are, in all human probability, never likely to be published again.
