The Mormons have found a new book called the Book of Abraham. It purports to have been written by that patriarch, and is said to have been found in the Catacombs of Egypt by an English traveller who brought it away with eleven mummies. Jo Smith is engaged in translating this book for the Nauvoo 'Times and Seasons.' The first chapter appears in the last number that has reached us. We presume the faithful will have no doubt of its authenticity. The Mormon paper also contains a fac simile engraving from the same manuscript, which adds very little to Abraham's fame, as far as drawing is concerned; it represents Abraham bound upon an altar, and the idolatrous priest of Elkenah attempting to sacrifice him to his gods, the images which surround the altar.
