It is with sincere satisfaction that the author is at length enabled to present to the public the following memoir. Had the long delay which has occurred in its appearance resulted from his own negligence, the pain which he has suffered in consequence would have been a severe, if not a sufficient punishment. But of such a charge he is perfectly guiltless. For his own relief, and for the success of his undertaking, he was most anxious that the volume should have been completed at a much earlier period; but as he was far more solicitous that it should not be published in an unfinished state, he was induced to await, in the first instance, the arrival of documents from the South Sea Islands, and subsequently, the return of Mrs. Williams to this country; and the issue has satisfied him, that in resisting the strong temptation to go to press, he did well. Thus he has been enabled to enrich some parts of his volume, to complete others, and accurately to trace his admirable friend through almost every interesting scene of his diversified and instructive history.
