Preface to the First Edition.
A narrative of this voyage was prepared for the ‘Congregationalist’ at the request of the editors, and appeared in successive numbers of that paper. On application of the present publisher for leave to issue it in a volume, it has assumed the form in which it now appears, revised and enlarged. The manner in which it originated explains its miscellaneous and somewhat desultory character.
Preface to the Second Edition.
So much interest in this narrative has been expressed that the author has been led to insert in a new edition things which it would have contained in the first, had the design been to give more than a brief sketch of the voyage.
