“Being firmly convinced that there could be no manifestation of one form of force without the corresponding expenditure of some other form of force, I for a long time searched in vain for evidence of any force or power being used up in the production of these results.
“Now, however, having seen more of Mr. Home, I think I perceive what it is that this psychic force uses up for its development. In employing the terms vital force or nervous energy, I am aware that I am employing words which convey very different significations to many investigators; but after witnessing the painful state of nervous and bodily prostration in which some of these experiments have left Mr. Home—after seeing him lying in an almost fainting condition on the floor, pale and speechless—I could scarcely doubt that the evolution of psychic force is accompanied by a corresponding drain on vital force.”
Sergeant Cox in speaking of the tests says, “The results appear to me conclusively to establish the important fact, that there is a force proceeding from the nerve-system capable of imparting motion and weight to solid bodies within the sphere of its influence.”
One of the medium’s defenders has written:
“Home’s mysterious power, whatever it may have been, was very uncertain. Sometimes he could exercise it, and at others not, and these fluctuations were not seldom the source of embarrassment to him. He would often arrive at a place in obedience to an engagement, and, as he imagined, ready to perform, when he would discover himself absolutely helpless. After a séance his exhaustion appeared to be complete.
“There is no more striking proof of the fact that Home really possessed occult gifts of some sort—psychic force or whatever else the power may be termed—than he gave such amazing exhibitions in the early part of his history and was able to do so little toward the end. If it had been juggling he would, like other conjurors, have improved on his tricks by experience, or at all events, while his memory held out he would not have deteriorated.”
Dr. Hammond’s Experiments.
Dr. William A. Hammond, the eminent neurologist, of Washington, D. C., took up the cudgels against Prof. Crookes’ “Psychic Force” theory, and assigned the experiments to the domain of animal electricity. He wrote as follows:[2] “Place an egg in an egg-cup and balance a long lath upon the egg. Though the lath be almost a plank it will obediently follow a rod of glass, gutta percha or sealing-wax, which has been previously well dried and rubbed, the former with a piece of silk, and the two latter with woolen cloth. Now, in dry weather, many persons within my knowledge, have only to walk with a shuffling gait over the carpet, and then approaching the lath hold out the finger instead of the glass, sealing wax or gutta percha, and instantly the end of the lath at L rises to meet it, and the end at L is depressed. Applying these principles, I arranged an apparatus exactly like that of Prof. Crookes, except that the spring balance was such as is used for weighing letters and was therefore very delicate, indicating quarter ounces with exactness, and that the board was thin and narrow.
