“It is noteworthy that when I carried out the same test about eighteen months previously, I obtained the same result within a pound or two. (See ‘Reality of Psychic Phenomena,’ Experiment 63, p. 142.) “_Experiment 2._--I asked the operators to put the matter they said they abstracted in Experiment 1, not on the floor but on the drawing-board under the medium’s chair (the drawing-board was resting on the platform of the weighing-machine). They gave three raps when the operation was complete. RESULT: “The medium’s weight showed no difference from her normal of 9 st. 12½ lbs. “This, of course, is as it should be, as any actual matter taken from her body and placed on the drawing-board would still be accounted for by the weighing-machine, provided that such matter was acted upon by gravity in the normal way.” Here, as is obvious, was a laboratory experiment of the simplest nature and not open to any doubt or cavil. It was a mere weighing operation to determine whether any loss of weight took place in the material objects on the platform of the machine. The medium, as a person, did not enter into the problem at all. It was not a question of her good faith any more than it was the question of the good faith of the chair or the drawing-board. Nor was it the case of a phenomenon occurring in darkness or under conditions that rendered close observation difficult; while, as for Dr. Crawford himself, it will not be contended that he was incompetent to read the indications of the machine or to report them correctly. Yet his spoken instructions to something invisible and intangible were followed by results that indicated intelligent hearing and careful obedience. To deny that this was strict scientific proof of the presence in Dr. Crawford’s laboratory of some kind of consciousness, perception and will--_i.e._ of some “soul”--that was separate and distinct from any soul in normal association with a human body would be to speak as perversely as though one were to deny that two and two make four. So much for the physical category of the observations that have been made in the scientific world respecting survival after death. We can now turn to the psychical category.
