not forget the possibility that telepathy was an element necessary to be eliminated. The possibility that she might read what was in his own mind must, therefore, be provided against. To that end he wrapped a large number of specimens in packages as nearly alike as possible, and mixed them together so that it was impossible for him to know them apart. One specimen after another would then be handed her, and each one would be described with the same accuracy as before. This was considered the supreme test, and the doctrine that "things," in common with men, have "souls," was thought to be demonstrated. The Orientalists would say that he had demonstrated that the history of all things is "recorded in the astral light," whatever that may be. The spiritist would say that the spirits of dead men had given her the information. The true explanation is obvious to those who are acquainted with the facts of telepathy. The professor was an eminent geologist and a classical scholar. In his subjective mind was the history of every geological specimen in his possession, pictured clearly and vividly, according to the theories of the best geologists of his generation. His imagination carried him back to the time when chaos reigned supreme. He followed the fragment of rock down through all the changes which took place in the earth's structure, until it became a part of the solid mass of rock from which it was taken. In the ever-changing environment of that fragment, since the time when it was a part of a vast mass of molten matter, there was material for pictures of the sublimest scenes incident to the formation of a world. Those pictures, to the imagination of every geologist worthy of the title, are ever present and intensely vivid. A fragment of rock to him is an open book, in which are recorded the history of the sublimest works of Omnipotence, and his imagination supplies the panoramic illustrations. In experiments such as have been described, these pictures are necessarily presented to the subjective mind of the percipient in a form so clear and vivid that she would be insensate indeed if she failed to describe them in appropriate terms. And when we consider the fact that the percipients employed in these experiments were exceptionally cultivated women, especially interested in the subjects of the professor's research, it will be seen that successful telepathic experiments were to them exceptionally easy.
