[Apostle Wilford Woodruff]
During the evening in company with Brother Cannon I Attended one of Le Roy Sunderland Lectures upon Patheism. He had some 10 persons in a state of Clarvoyance And About a dozen asleep And many affected in the first degree. He classes his Mesmerism under 3 degrees 1 2 3 But it is evident in a great measure that his operation are a money making scheme. Those in the third degree are trained subjects And I could free-quently see the Cloven foot manifest.
