“Then she shall be yours,” the physiologist said with decision, “for you are a good-hearted young man, and one of the best neurotic subjects that I have ever known--that is when you are not under the influence of alcohol. My experiment is to be performed upon the fourth of next month. You will attend at the physiological laboratory at twelve o’clock. It will be a great occasion, Fritz. Von Gruben is coming from Jena, and Hinterstein from Basle. The chief men of science of all South Germany will be there. “I shall be punctual,” the student said briefly; and so the two parted. The Professor plodded homeward, thinking of the great coming event, while the young man staggered along after his noisy companions, with his mind full of the blue-eyed Elise, and of the bargain which he had concluded with her father. The Professor did not exaggerate when he spoke of the widespread interest excited by his novel psychophysiological experiment. Long before the hour had arrived the room was filled by a galaxy of talent. Besides the celebrities whom he had mentioned, there had come from London the great Professor Lurcher, who had just established his reputation by a remarkable treatise upon cerebral centres. Several great lights of the Spiritualistic body had also come a long distance to be present, as had a Swedenborgian minister, who considered that the proceedings might throw some light upon the doctrines of the Rosy Cross. There was considerable applause from this eminent assembly upon the appearance of Professor von Baumgarten and his subject upon the platform. The lecturer, in a few well-chosen words, explained what his views were, and how he proposed to test them. “I hold,” he said, “that when a person is under the influence of mesmerism, his spirit is for the time released from his body, and I challenge any one to put forward any other hypothesis which will account for the fact of clairvoyance. I therefore hope that upon mesmerising my young friend here, and then putting myself into a trance, our spirits may be able to commune together, though our bodies lie still and inert. After a time nature will resume her sway, our spirits will return into our respective bodies, and all will be as before. With your kind permission, we shall now proceed to attempt the experiment.” The applause was renewed at this speech, and the audience settled down in expectant silence. With a few rapid passes the Professor mesmerised the young man, who sank back in his chair, pale and rigid. He then took a bright globe of glass from his pocket, and by concentrating his gaze upon it and making a strong mental effort, he succeeded in throwing himself into the same condition. It was a strange and impressive sight to see the old man and the young sitting together in the same cataleptic condition. Whither, then, had their souls fled? That was the question which presented itself to each and every one of the spectators.
