CLASSIFICATION ACCORDING TO METHODS. The classification of Clairvoyant Phenomena according to methods employed, proceeds as follows: (1) PSYCHOMETRY, in which the clairvoyant becomes en rapport through the medium of some physical object connected with the person or scene which is the object of the en rapport connection; (2) CRYSTAL GAZING, etc., in which the en rapport connection is established by means of a crystal, magic mirror, etc., into which the clairvoyant gazes; (3) DIRECT CLAIRVOYANCE, in which the clairvoyant directly establishes the en rapport connection by means of raising his or her psychic vibrations so as to become "in tune" with the finer vibrations of Nature, without the aid of physical objects. Classification According to General Distinctions. The classification of Clairvoyant Phenomena according to general distinctions, proceeds as follows: (1) PRESENT CLAIRVOYANCE, in which the objects perceived by the clairvoyant are present in Space and Time, although invisible to normal sight; (2) SPACE CLAIRVOYANCE, in which the clairvoyant vision includes objects and scenes removed in space from the immediate normal perception of the clairvoyant; (3) TIME CLAIRVOYANCE, in which the clairvoyant perceives objects or scenes removed from him in past time, or future time. In order that the student may obtain a comprehensive understanding of the phenomena of Clairvoyance, we have thought it well to give you a brief, general outline of the particular phenomena fitting into these several classes, and to give you, also, a general idea of the principal methods employed to obtain the phenomenal manifestations in question. We begin by calling your attention to the three general classes of method employed to obtain the manifestation of clairvoyant phenomena, namely: Psychometry, Crystal Gazing, and Clairvoyant Psychic States, respectively. Psychometry. In Psychometry, the clairvoyant establishes the en rapport connection with objects, persons or scenes, removed in space or in time, by means of some physical object associated with the distant object, person or scene; for instance, the physical objects may be a piece of clothing, a bit of stone, a coin, a bit of jewelry, etc., which has been closely associated with that which the clairvoyant desires to sense psychically. The distinctive feature of this class of clairvoyant phenomena is this CONNECTING LINK of physical objects. A writer has cleverly compared this connecting link with the bit of clothing which the keen-scented bloodhound is given to sniff in order that he may then discover by scent the person sought, the latter having previously worn the bit of clothing presented to the dog's sense of smell. The "Psychic Scent."
