ANOTHER MORMON HUMBUG.—The Mormons pretend to have found another inspired work 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. This book 'brings fresh grist to the Mormon mill.' The most unqualified chaff scattered on the winds is sure to bring some foolish birds down to pick at it.
