Under this title Mr. Crookes cites facts that cannot be classed otherwise by reason of their complex character. As an example, he reports two cases: one being an experiment in typtology between himself, Miss Fox, and another lady. He proved that a bell that belonged in his business office was brought to the table, as a proof announced by the intellectual force, that communicated with him, _of its strength_. The chamber in which this was done was separated from the office by a door which he previously securely locked with a key, and he was absolutely positive that the bell in question was in his office. “The second case I desire to report,” says Mr. Crookes, “took place one Saturday night under a full glare of light, Mr. Home and my family being the only persons present. “My wife and I, having passed the day in the country, had brought home flowers with us that I had gathered; on arriving at home we had given them to a servant to put in water. Mr. Home came shortly after and we went into the dining room. At the instant we seated ourselves, the domestic brought the flowers, arranged in a vase; I placed them in the center of the table, which was not covered by a cloth. It was the first time Mr. Home had seen these flowers. “Immediately a message came, given by the rap alphabet, which said, ‘It is impossible for matter to pass through matter, but we will show you that we can do it.’ We waited in silence, and soon a luminous apparition was seen floating over the bouquet of flowers, and then, in full view of all my family at the table, a branch of China grass, fifteen inches in length, which ornamented the middle of the bouquet, slowly rose from the bunch of flowers, descended from the vase and moved across the table, and my wife saw a hand stretched out from under the table and seize the flower; at the same moment she was struck three times on the left shoulder and the noise made by the slaps was so loud we all heard it; then the luminous hand dropped the China grass to the floor and disappeared. Only two persons of my family saw the hand, but every one at the table noticed the different movements of the plant stalk, as I have before described them. “During the time that this phenomena lasted we all saw Mr. Home’s hands on the table, where they rested motionless, and they were at least eighteen inches from where the plant stalk disappeared. “It was a dining-room table that opened in folds, it did not lengthen,” etc.
