We have been told of a lady, who, in a magnetized state, sits at a table and writes down information that is imparted to her, as is said, from the world of spirits. Her hand and pen glide over the paper with astonishing speed and velocity, far more rapid than the most expert penman in a normal state. And what astonishes many is, that she cannot stop writing when she wishes to, and sometimes becomes so exceedingly fatigued as to beg of the spirit or spirits to grant her a little repose from the wearisome task. But the whole matter is easily accounted for, without referring it to the supposed agency of spirits. The lady's arm is first paralyzed--deprived of motion by the will of the medium or operator, so that her own mind or will has not the least control over it. She thus becomes a mere machine, under the will and control of another, whose will directs the movements of the arm and pen, and dictates what is written in answer to inquiries made of things appertaining to the spirit world, just as Miss Martineau declares, in her letters on magnetism, that "the volitions of the mesmerist may actuate the movements of the patient's limbs, and suggest the material of his ideas." Many singular effects are produced upon the minds and feelings of subjects in a sleep-waking state, by Professor Williams, Dr. Cutter, and others, such as being made drunk with water, eating cayenne as sugar, exercising complete control over their mental as well as physical condition. We have been assured by a pathetist, who is a thorough adept in the profession, that he _can_ and often _has_ put persons in communication _apparently_ with a deceased father, mother, brother, sister, or friend. The individual is first _pathetized_ (another name for mesmerism) by him in a wakeful state, though unconscious, it may be, that he is under such an influence. His mind being in the possession and under the control of the operator, a person is now either actually or mentally (for it makes no difference) presented before him, and he is told of the fact, and asked, _Do you not see your father?_ The idea of _father_ is so presented to the mind, through the organ of _form_, that the organ can take cognizance of none other than the father. The _person_, if an actual person is employed for the occasion, is then shifted or changed for another person; yet the subject perceives no difference, even if changed successively for a dozen others; it is all the same; it is _father_, and no one else, through the whole exhibition. The father speaks, the son recognizes his voice, and they converse together. The subject can be willed to hear any sound, as that of music, artillery, thunder, and the like, though no sounds whatever are in reality made. A niece of ours was operated on in this way, and she was told to look abroad and behold the majestic waves of the ocean, the pageantry of a military procession; and she saw and was delighted with the scenes that were _willed_ to pass before her.
