suggest that the same process as that of dreaming gives rise to the ghosts themselves. Great is the Sub-Consciousness! Who shall say what it does not contain, either _in esse_ or _in posse!_ Till we have exhausted the Sub-Consciousness let us not talk of spooks. Two things alone remain to be considered. One is how the Planchette or the table is able to read cards placed face downwards upon it; the second is, is telepathy or thought-transference a possibility? As to the first point I have never yet been able to satisfy myself whether the results are more than Chance would account for; for Chance has strange vagaries--themselves part of the doctrine of Chances--and in order to decide, one would have to make a far more extended induction than I have had time for. But if the mathematical probabilities are really exceeded, one would be driven to the suspicion that there resides in the Sub-Consciousness a sense of which we are unaware, perhaps an extra way of perceiving by the tips of the fingers, which may be either a new embryonic sense, not yet developed by the struggle for existence, or the rudimentary survival of an old sense eliminated in the struggle, perhaps a relic from those primeval homogeneous organisms in which every part of the body did every kind of work. After all, the senses are all developments of the sense of touch. This suspicion is strengthened by the fact that the correct card is often given at the first trial, and not after, as if this unused sense were soon exhausted. By the way, though the "spirits" mostly failed to tell a card placed face down, and unknown to any one in the room, they were invariably successful when it was placed face up: a sufficient proof--is it not?--that there could be nothing in the replies which was not already in some one's mind.
