242 THE LAW OF PSYCHIC PHENOMENA.
meant to imply that there is any doubt of the existence of a power which is generally known as clairvoyance, but that its limitations are as yet undecided. That is to say, the boundary line between clairvoyance and telepathy- is not at present clearly drawn. The field of clairvoyance is constantly narrowing its boundaries. Thus, a few years ago every perception of a fact not cognizable by the senses was attributed either to clairvoyance or to spirits. Sceptics on the latter subject were wont to explain certain phenomena by attributing them to the former. The phenomena which could not thus be explained were relegated to the domain of fraud and legerdemain. When the phenomena of telepathy became better understood, the field of clairvoyance was greatly narrowed, as it was found that most of the phenomena before explained by clairvoyance were really due to telepathic communion. But the powers and limitations of telepathy are not yet clearly marked; and it is found that every step in advance in the knowledge of its principles by just so much narrows the field of clairvoyance. No better illustration of this fact could be given than the phenomena of psychometry, which we have just been considering. The power to read the history of a geological specimen with a plausible show of accuracy was first attributed to clairvoyance. As telepathic powers began to be understood, it was thought that possibly the percipient simply related what was read in the mind of the agent. Many experiments were made throughout the country which demonstrated that fact, and the recognized field of clairvoyance was thereby curtailed. But Professor Denton determined to eliminate the element of telepathy by so disposing of his relics as to divest himself of all knowledge of the particular one .under examination. When the percipient exhibited the same powers of discernment under those circumstances it was thought that the element of telepathy was eliminated, and that the power of clairvoyance was demonstrated. But as the knowledge of telepathy is increased, and when it is understood that telepathy is the communion of subjective minds, and that the subjective mind is endowed
