New-York Daily Tribune 1, no. 306 (April 2, 1842): [2]
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.
