Of the many experiments described in this report we will quote here but one:

"On one occasion, when eleven members of your sub-committee had been sitting around one of the dining-tables above described for forty minutes, and various sounds and motions had occurred, they, by way of test, turned the backs of their chairs to the table, at about nine inches from it. They all then knelt upon their chairs, placing their arms upon the backs thereof. In this position their feet were of course turned away from the table, and by no possibility could be placed under it or touch the floor. The hands of each person were extended over the table, at about four inches from the surface. Contact, therefore, with any part of the table could not take place without detection. In less than a minute the table, untouched, moved four times,—at first about four inches to one side, then about twelve to the other side, and then, in like manner, four and six inches respectively."

The committee further remarks that after this experiment "the table was carefully examined, turned upside down, and taken to pieces, but nothing was discovered to account for the phenomenon. Delusion was out of the question. The movements were in various directions, and were witnessed simultaneously by all present. They were matters of measurement, and not of opinion or fancy. Your sub-committee have not collectively obtained any evidence as to the nature and source of this force, but simply as to the fact of its existence."

Mr. Sergeant Cox, a member of this sub-committee and a prominent member of the English bar, relates that he experimented elsewhere in the same manner as that above described, and with similar results, a heavy dining-table being employed. Afterward, when all the party stood in a circle round the table, holding hands, at first two and then three feet distant, the table lurched four times, once more than two feet and with great force, and moved to such an extent as to become completely turned round. After the party had broken up, and were standing in groups about the room, the table, which was about two feet from its original position, swung violently back to its proper place and set itself exactly square with the room, with such force as literally to knock down a lady who was standing in the way putting on her shawl for departure.

Mr. Cox, after a close examination of these phenomena, offered a theory in explanation somewhat differing from that already mentioned. He believes that they are due to the action of some psychic force, originating in the nervous system and analogous in character to magnetic attraction. He relates several instances of heavy bodies moving toward the mediums, as if attracted, and remarks, "In another experiment in my own lighted drawing-room, as the psychic [the medium] was entering the room with myself, no other person being there, an easy-chair of great weight that was standing fourteen feet from us was suddenly lifted from the floor and drawn to him with great rapidity, precisely as a heavy magnet will attract a mass of iron."

Another phase of these phenomena, as observed by the committee, was the sudden and considerable change of weight in the table, it becoming light or heavy as desired. To prove this scientifically, a weighing-machine was attached, and the change of weight clearly proved. "One instance will suffice. Weighed by the machine, the normal weight of a table raised from the floor eighteen inches on one side was eight pounds. Desired to be light, the index fell to five pounds; desired to be heavy, it advanced to eighty-two pounds. And these changes were instantaneous and repeated many times."

The most remarkable evidence adduced by scientific observers is that presented by Professor Crooks. He is a chemist of high reputation, the editor of the "Chemical News" and for many years of the "Quarterly Journal of Science," the discoverer of the metallic element thallium, and of recent years noted for his remarkable discoveries in the conditions of matter in highly-exhausted vacuum-tubes. In 1870 he undertook the investigation of Spiritualism, with the full expectation of exposing it as a compound of trickery on the one side and of credulity and self-deception on the other. In January, 1874, he published, in the "Quarterly Journal of Science," a brief compend of the notes of his investigations during the four years preceding. Some of the phenomena here recorded are so extraordinary that they would not be worthy an instant's attention but for the attestation of a witness of such standing, and one accustomed to the employment of the severest scientific tests.

The phenomena recorded, as he declares, with few exceptions, all took place in his own house and in full light, at times appointed by himself, "and under conditions that absolutely precluded the employment of the very simplest instrumental aid." In all cases only private friends were present besides the medium. The mediums employed were the noted D. D. Home and Miss Kate Fox, of Rochester-rappings notoriety. Of the simpler phenomena observed were the movement of heavy bodies with contact, but without mechanism or exertion, percussive and other sounds, etc. He remarks,—

"I have had these sounds proceeding from the floor, walls, etc., when the medium's hands and feet were held, when she was standing on a chair, when she was suspended in a swing from the ceiling, when she was enclosed in a wire cage, and when she had fallen fainting on a sofa. I have had them on a glass harmonicon. I have felt them on my own shoulder and under my own hands. I have heard them on a sheet of paper held between the fingers by a piece of thread passed through one corner. I have tested them in every way that I could devise; and there has been no escape from the conviction that they were true objective occurrences, not produced by trickery or mechanical means." Intelligence is manifested by these sounds, "sometimes of such a character as to lead to the belief that it does not emanate from any person present."

He records numerous instances of the movement of heavy bodies when not touched: "My own chair has been twisted partly round while my feet were off the floor. A chair was seen by all present to move slowly up to the table from a far corner when all were watching it; on another occasion an arm-chair moved to where we were sitting, and then moved slowly back again (a distance of about three feet) at my request."
