The writer in the _Quarterly Review_, to whom I have before referred, shall give us the next example from his own experience (vol. 131, p. 331). He owns that, on one occasion, he was "strongly impressed" by a spiritualistic manifestation. "He (the medium, Mr. Foster) answered, in a variety of modes, the questions we put to him respecting the time and cause of the death of several of our departed friends and relatives, whose names we had written down on slips of paper, which had been folded up and crumpled into pellets before being placed in his hands. But he brought out names and dates correctly, in large red letters on his bare arms, the redness being produced by the turgescence of the minute vessels of the skin, and passing away after a few minutes like a blush. We must own to have been strongly impressed at the time by this performance; but, on subsequently thinking it over, we thought we could see that Mr. Foster's divining power was partly derived from his having the faculty of interpreting the movements of the top of pen or pencil, though the point and what was written by it was hid from his sight; and partly from a very keen observation of the indications unconsciously given by ourselves of the answer we expected." Indubitably in the case of two accomplices, a preconcerted system of movements of the top of the pencil might be made to indicate what was written; but, considering the enormous variety of ways of writing, that any one can acquire the art of so reading chance writing is incredible. At best this explanation only applies to the questions. The answers, which were given "correctly," in the shape of dates and causes of death, etc., in red letters on the medium's arm, must have been read in the reviewer's unconscious contortions. The force of the reviewer's admission of the accuracy of these communications is not affected by the fact that when _another_ way of answering questions was adopted--viz., the questioner pointing successively to the letters of the alphabet, until interrupted by the rap--there were indications of his manner being read by the medium. Again, it is little to the purpose that "the trick by which the red letters were produced was discovered by the inquiries of one of our medical friends"--a most curiously vague statement, by the bye--for the mystery to be explained is not the red letters, but the correctness of the information they conveyed. There is nothing in the necessity of some sort of _rapport_ existing between the medium and his questioner inconsistent with the spirit hypothesis; there is nothing in the subsequent experiments of the reviewer even tending to a natural explanation of what had so strongly impressed him; and yet he is able to shake off the strong impression triumphantly. One begins to appreciate the eloquent words of Professor Tyndall:[50] "The logical feebleness of science is not sufficiently borne in mind. It keeps down the weed of superstition not by logic, but by slowly rendering the
