I could not find an actual copy for sale, but the
Library of Congress does have it. Not sure if that link will work or not. If it does, scroll down to the bottom for
viewing options. (I've never tried this, so I do not know how it works and unfortunately I am pressed for time at the moment and cannot try it.)
If all else fails, stop by the Historical Society in Concord. I guess they haven't scanned this book.
Good luck! Let us know how you make out!
