Phineas Parkhurst Quimby, The Quimby Manuscripts (1921)
“ Mr. Quimby's manner of operating with his subject was to sit opposite to him, holding both his hands in his, and looking him intently in the eye for a short time, when the subject would go into the state known as the mesmeric sleep, which was more properly a peculiar condition of mind and body, in which the natural senses would, or would not, operate at the will of Mr. Quimby. When conducting his experiments, all communications of Mr. Quimby with Lucius were mentally given, the subject replying as if spoken to aloud. ”
