He came round to that as the concluding exhibition in his performance. “I have shown you,” he said, “that a mesmerised subject is entirely dominated by the will of the mesmeriser. He loses all power of volition, and his very thoughts are such as are suggested to him by the master-mind. The same end may be attained without any preliminary process. A strong will can, simply by virtue of its strength, take possession of a weaker one, even at a distance, and can regulate the impulses and the actions of the owner of it. If there was one man in the world who had a very much more highly-developed will than any of the rest of the human family, there is no reason why he should not be able to rule over them all, and to reduce his fellow-creatures to the condition of automatons. Happily there is such a dead level of mental power, or rather of mental weakness, among us that such a catastrophe is not likely to occur; but still within our small compass there are variations which produce surprising effects. I shall now single out one of the audience, and endeavour ‘by the mere power of will’ to compel him to come upon the platform, and do and say what I wish. Let me assure you that there is no collusion, and that the subject whom I may select is at perfect liberty to resent to the uttermost any impulse which I may communicate to him.” With these words the lecturer came to the front of the platform, and glanced over the first few rows of the stalls. No doubt Cowles’ dark skin and bright eyes marked him out as a man of a highly nervous temperament, for the mesmerist picked him out in a moment, and fixed his eyes upon him. I saw my friend give a start of surprise, and then settle down in his chair, as if to express his determination not to yield to the influence of the operator. Messinger was not a man whose head denoted any great brain-power, but his gaze was singularly intense and penetrating. Under the influence of it Cowles made one or two spasmodic motions of his hands, as if to grasp the sides of his seat, and then half rose, but only to sink down again, though with an evident effort. I was watching the scene with intense interest, when I happened to catch a glimpse of Miss Northcott’s face. She was sitting with her eyes fixed intently upon the mesmerist, and with such an expression of concentrated power upon her features as I have never seen on any other human countenance. Her jaw was firmly set, her lips compressed, and her face as hard as if it were a beautiful sculpture cut out of the whitest marble. Her eyebrows were drawn down, however, and from beneath them her grey eyes seemed to sparkle and gleam with a cold light.
