"The importance of the question, Where are the Ten Tribes of Israel? the speedy sale of the first edition of this work; and the obtaining considerable additional evidence relative to the origin of the American Indians; have led the way to the publishing of a second edition of this View. Additional evidences are adduced from various sources; especially from Hunter"s Narrative - Baron Humboldt on the Kingdom of New Spain - and the American Archaeology. These authors, without particular design, have furnished what is deemed material evidence upon this subject." - Ethan Smith, from the 1825 edition.
