PREFACE.

TWENTY-ONE years have passed since William Penn, an Historical Biography,' came out. The book obtained some favour, not in England only, but in Germany and America. Yet it has long been out of print; awaiting that revision which an author who respects his public likes to give his final work. In one-and-twenty years, much light has come to us from public offices, both home and foreign; and in dealing with a mass of new materials I have been led to write my book afresh. The change of title hardly corresponds to the material change. It would be no misuse of words to say that William Penn: Founder of Pennsylvania,' is substantially a new book.
