Now, in point of fact, the evidence bearing out the claim that she saw and talked with the dead is practically confined to the account written by the mourning Kerner, whom no one would for a moment call an unprejudiced witness. Already deeply immersed in the study of the marvelous, his mind absorbed in the weird phenomena of the recently discovered science of animal magnetism, she came to him both as a patient and as a living embodiment of the mysteries that held for him a boundless fascination, and once he found reason to believe in her alleged supernormal powers, there was nothing too fantastic or extravagant to which he would not give ready credence and assent. His lengthy record of "facts" includes not only what he himself saw or thought he saw, but every tale and anecdote related to him by the seeress and her friends, and also includes so many incidents of supernaturalism on the part of others that it would well seem that half the peasant population of Wuertemberg were ghost seers. Besides this, detailed as his narrative is, it is lacking in precisely those details which would give it evidential value; so lacking, indeed, that even such a spiritistic advocate as the late F. W. H. Myers pronounced it "quite inadequate" for citation in support of the spiritistic theory. Nevertheless, taking his extraordinary document for what it is worth, careful consideration of it leads to the conclusion that it contains the story not so much of a great fraud as of a great tragedy. It is obvious that there was frequent and barefaced trickery, particularly on the part of Frederica's sister and the ubiquitous servant girl; but it is equally certain that Frederica herself was a wholly abnormal creature, firmly self-deluded, one might say self-hypnotized, into the belief that the dead consorted with her. And it is hardly less certain that in her singular state of body and mind she gave evidence not indeed of supernatural but of telepathic and clairvoyant powers on which she and those about her, in that unenlightened age, could not but put a supernatural interpretation.
