The subject of this letter is to be the magnetoscope. The pamphlet by Mr. Rutter shall be sent you. Since its publication new discoveries have been made and amply tested, and of these I will try to give you some account. One objection received as conclusive against the reality of the magnetic influence from the operator was that the motions of the pendulum suspended from the instrument were produced solely by unconscious muscular movement on the part of the operator. Although to engineers and persons acquainted with the laws of motion this rotation of the pendulum in the instrument appeared to be a strange new mechanical power, yet the Royal College of Physicians and the ‘Lancet’ decreed that it should be explained by involuntary muscular movement, and one M.D. of eminence wrote a letter to me implying that believers in the magnetoscope were to be classed with Mormons. It has since been proved beyond a doubt by Mr. Rutter that the touch of the poles of a magnet or crystal to the spot before touched by the hand will be followed by movements exactly similar, the rotation being from east to west or from west to east, according as the north or south pole of the crystal is directed to the spot. After _contact_ it occurred to Mr. R. to try _pointing only_ with the poles of the crystal _held in his hand_. The same effect ensued. What becomes of the muscular impulse theory? Another objection is now considered as fatal—that when the eyes are closed all motion is stopped if the operator is either holding the thread or touching the magnetoscope. Ergo, they say, it is all imposture. But is there not another light thrown by this on the power of the eyes—on their ‘electric glance’? It is stated in Carpenter’s ‘Animal Physiology’ that a woman whose left arm was palsied could hold up a child with it _as long as she looked at it_. When she closed her eyes the arm dropped. A Mr. John Dimson, well known now in Brighton, has a paralytic affection of his feet, and cannot walk unless _he fixes his eyes upon them_. To this fact Mr. and Mrs. Bracebridge (Florence’s friends) and Lady Easthope have recently given me their attestation as eye-witnesses, and I understand that the fact is observed at German baths for lame patients.
