Under this interesting disposition for magnetic union, the eyes of the maiden being fixed on the magnetizer intensely, _his_ hands were passed before her body, his fingers thus forming natural conductors, by which the magnetic fluid was conveyed from the positive to the negative magnetic body. Then came the wonders of this influence. The patient was warmed by the benevolence of the magnetizer, who felt an _aura_ or tingling in the part corresponding to any painful part of the patient’s body which was relieved or cured. Indeed, Bertrand assures us that many told him they saw a _blue fluid streaming from his fingers_ when he magnetized them. The secret of this is closely analogous to the effect of brooding over sorrow: the mind of the patient is _concentrated_ on the spot to which the passes are directed; and, as we know that _disease_ can be excited thus by imagination (especially in the hypochondriac), so it is a truth that this concentration may _remove_ disease and pain, especially by the superaddition of faith.

She went back again, and that trembling left me. She seated herself under the canopy and said, ‘Will not the gentleman sit down?’ Hereupon Mr. Professor Hensler said to her, she should see me. So as she drew nigh to me, within two or three steps, I was still more unwell than before, and I felt pains in all my limbs. Mr. Professor Hensler told her that I was the man who had been wounded (that is, by the attempt which had been made to assassinate him); at the same time she noticed my scar, and pointed towards it; then came the air strong upon my forehead, and I felt pain in it, also my left foot began to tremble greatly. The sick person seated herself under the canopy, and said that she was ill; and I also said that I was so unwell that I must sit down. I sat down in the other room: now the other foot began to twitter. Although Mr. Von Gutter held my knees, I could not keep them still. Now a violent beating of my heart came on me, and there was a heat in all my body: that beating of the heart left me
