220 THE LAW OF PSYCHIC PHENOMENA.
Of clairvoyance little will be said, for the reason that it is still an open question among scientists who have been, and are still, investigating the subject, whether independent clairvoyance exists as a power of the human mind. Sufficient evidence has not been brought to my attention to demonstrate its existence. Certainly the great bulk of phenomena which are popularly regarded as evincing clairvoyant power must now be referred to telepathy. It must be said, however, that many phenomena have been produced which cannot at present be accounted for on any other hypothesis than that of independent clairvoyance. Yet it is not impossible that, when the laws of telepathy are better understood, all so-called clairvoyant phenomena may be referred to that agency. For the purposes of our argument, however, it is not specially important that the distinction should be clearly drawn between the two, inasmuch as telepathy, which is an undoubted power of the subjective mind, sufficiently explains all the so-called spiritistic phenomena involving the perception by the medium of facts not within his own experience or his previous knowledge. I will therefore first treat of those phenomena the mysteries of which are directly and primarily referable to telepathy.
A very simple experiment will enable almost any one to demonstrate telepathic power. Let a person be securely blindfolded, by taking a pair of kid gloves, folding them into pads, placing them over his eyes, and binding them on by means of a handkerchief. Then let a circle be formed by a few persons, with their hands joined, the percipient forming one of the circle. Let a card be selected at random from a pack, taking care that no one sees any other card of the pack, even for an instant, until the experiment is over. Th*en place the card in plain sight of all but the percipient, and let them fix their minds and gaze upon the card, and in silence await the result. In the mean time the percipient should be and remain in a perfectly passive and tranquil frame of mind, and simply watch for visions. He will soon begin to see indistinct objects floating in the darkness, and
