A gentleman, about thirty years of age, when the mesmeriser held his outstretched hands pointed to his head, experienced no disposition to sleep; but in two or three minutes he began to shake his head and twist his features about; at last, his head was jerked from side to side, and forwards and backwards, with a violence that looked alarming. But he said, when it was over, that the motion had not been unpleasant; that he had moved in a sort voluntarily—although he could not refrain from it. If the hands of the operator were pointed to his arm instead of his head, the same violent jerks ensued, and gradually extended to the whole body. I asked him to try to resist the influence, by holding his arm out in strong muscular tension. This had the effect of retarding the attack of the jerks, but, when it came on, it was more violent than usual. I have lately seen another similar case. The seizure is evidently a form of St. Veitz’s dance brought out by the operation of the Od force. In neither of these two cases could trance be induced. A servant of mine, aged about twenty-five, was mesmerized by Lafontaine, for a full half-hour, and, no effect appearing to be produced, I told him he might rise from the chair and leave us. On getting up he looked uneasy, and said his arms were numb. They were perfectly paralyzed from the elbows downwards, and numb to the shoulders. This was the more satisfactory, that neither the man himself, nor Lafontaine, nor the four or five spectators, expected this result. The operator triumphantly drew a pin and stuck it into the man’s hand, which bled, but had no feeling. Then heedlessly, to show it gave pain, Lafontaine stuck the pin into the man’s thigh, whose flashing eye, and half suppressed growl, denoted that the aggression would certainly have been returned by another, had the arm which should have done it not been really powerless. However, M. Lafontaine made peace with the man, by restoring him the use and feeling of his arms. This was done by dusting them, as it were, by quick transverse motions of his extended hands. In five minutes nothing remained of the palsy but a slight stiffness, which gradually wore off in the course of the evening. Occasionally partial tonic spasm (improperly termed catalepsy, for it is of the nature of catochus, and the rigidity attending it is absolute) supervenes as the only consequence of mesmerising a limb. This result, which is not less alarming to the patient who has not been led to expect it than the preceding, may be got rid of in the same way. If you point with your fingers to the rigid muscles, or again, as it were, dust the limb with brisk transverse passes, or breathe upon it, the stiffness is thawed and disappears. Trance is seldom induced by mesmeric passes without more or less partial muscular rigidity of this kind supervening; it always yields to the means which have been mentioned.
