JO. SMITH'S MUMMIES.—About a year since, Mr. Wyman of the museum, purchased two mummies, one of each sex, from a gentleman who had purchased them directly from the widow of Jo. Smith. They were part of the four which Smith pretended to have found with ancient manuscripts, edited by the old patriarchs. While the mother of Smith lived, these mummies, with the hyeroglyphics upon papyrus which accompanied them, could not be obtained, but not long after her death they were purchased, as stated, from the prophet's widow. Some of the brethren have had the hardness to deny that these were the patriarchal manuscripts and relics. But an unanswerable confirmation of the fact has lately occurred; certain plates issued by the elders as fac similies of the original having fallen into Mr. Wyman's hands, which plates are fac similies of the hyeroglyphics in the museum. Let, then, all of Mormon faith go to the museum, and contemplate the veritable handwriting of the patriarch Abraham. Who knows that the patriarch himself, "and Sarai his wife," are not in the museum?
