Apostle Orson Hyde arrives in Nauvoo. However he later gives elaborate personal reminiscences of a "transfiguration" he could not possibly have witnessed. Hyde reports, in 1869 that when Brigham Young began to speak to the Saints on Aug 8, 1844, "his words went through me like electricity." This is my testimony, Hyde added for special emphasis, "it was not only the voice of Joseph Smith but there were the features, the gestures and even the stature of Joseph before us in the person of Brigham." In 1877 Hyde declares in general conference, "I heard the voice of Joseph through him, and it was as familiar to me as the voice of my wife, the voice of my child, or the voice of my father. And not only the voice of Joseph did I distinctly and unmistakably hear, but I saw the very gestures of his person, the very features of his countenance, and if I mistake not, the very size of his person appeared on the stand. And it went through me with the thrill of conviction that Brigham was the man to lead this people."
