was noted, and supernormal information frequently given.

      Now, it seems plausible to suppose that, by way of analogy, the medium trance would represent a trance state induced by hypnotism from the "other side." We know that telepathic hypnotism is a fact—the numerous cases recorded by Myers and Janet being good proof of this. Further, we know that dreams may be induced experimentally, by means of telepathic suggestion. (See Ermacora's paper, Proceedings, xi. 235–308.) Might we not assume, then, that the medium-trance represents a certain condition induced by influence from deceased minds—which would fully account for the supernormal information given (for the medium would be en rapport with these minds), and for the fact that the medium is not usually susceptible to suggestion, pain-tests, &c., on this side. The deeper the trance, the more the medium is in touch with the other world, the less with this; and vice versa. The medium-trance is, therefore, probably a hypnotic or mesmeric trance, induced telepathically by operators out of the body.

      10. When the trance has been induced, however, how does the "spirit" succeed in imparting information to the medium's brain and organism? Inasmuch as the phenomena are usually of the motor type—speech or writing—the motor centres in the brain must somehow be employed; how they are employed, and whether other centres in addition to these are used is a question calling for solution—but one which will take probably years of patient research to solve.

      As we know, Dr. Hodgson was of the opinion that the ordinary centres were not used in the production of the automatic writing, for he said (Proceedings, xiii. pp. 398–9): "What the precise relation is between this consciousness and the movements of the hand I do not know. I do not know whether or not the motor centres of the brain ordinarily concerned in the movements of hand and arm are in operation or not. I incline to think not—certainly not in the ordinary way. … " The statement of the "controls" is that they use the "empty corners" of Mrs. Piper's brain—which probably means that certain unused areas are pressed into service, as far as possible, in the production of the phenomena. Still, this is not very definite information! Another theory offered by the communicators is that they get into contact with the "light," think their thoughts, and these thoughts are then registered or expressed in motor phenomena—speech or writing. What the "light" may be, we have not the slightest means of knowing, but it is a very significant fact that a "light" of this nature is nearly always associated with spiritual phenomena. We hear of the "interior illumination" of the saints and martyrs, and of those who have experienced an influx of "cosmic consciousness"; of the "halo" which surrounds the heads of holy persons; of the "internal light" experienced by many who have had a special conversion or illumination; of the "aura" surrounding the bodies of certain individuals—always perceptible to clairvoyants, and lately (it is asserted) to any one who observes the subject through specially prepared chemical screens;[3] of the "light" diffusing itself over the region of the forehead, which certain mesmeric subjects have inwardly perceived,[4] and of the "aura" which may be produced experimentally by means of high-tension electric currents. We must not forget, also, that Christ Himself is called "the light of the world," and that He once made the very significant remark: "If thine eye be single, thy whole body shall be full of light." Lastly, it is somewhat significant, it seems to me, that Andrew Jackson Davis used to see the nervous system of the person he was studying, while in the "superior condition," as light—as though it were illuminated by some interior glow, or was more or less phosphorescent. (And we know that phosphorus is certainly connected with the activities of the nervous system—even though it be not so intimately as before supposed.) This string of coincidences is at least remarkable; and it will be observed that the "light" is usually associated with nervous centres and nervous activity—for the head, e.g., is certainly the part most highly illumined, as a rule; while it is certainly the seat of the most active self-consciousness.

      11. These facts throw an interesting side-light, also, upon another oft-observed phenomenon in psychical research. I refer to the fact that apparitions ("ghosts") are nearly always seen to be clear and distinct as to the head and upper portions of the body, while they taper off to vapour and "filmy nothingness" in the lower limbs, so that often the feet are not visible at all. While this may be due in part to the fact that the observer's attention is not directed to the lower limbs, but more or less centred upon the head and face, it appears to me that there may be another interpretation of the facts, more in accordance with the phenomena above mentioned, which is this:

      During life we are conscious of our body in varying degrees—of the head most of all, then of the arms and upper portions of the body; and finally, of the lower limbs and feet, we are, a large part of the time, hardly conscious at all. Now, if the light accompanies nervous activity, and is present in proportion to it, it is obvious that those portions of the organism would have most "light" which were most active mentally—i.e., the brain and those portions of the nervous system controlling the hands, face, and upper portions of the body—while those portions which had become entirely automatic and unconscious in their activity would have least light—being physiological to the point almost of being mechanical. If this "light" corresponded in any way to visibility, therefore, it would only be natural to suppose that the face and upper portions of the phantasmal figure should be more or less distinctly visible, to one at all sensitive to such impressions, while the lower portions of the figure would fade into practical invisibility—owing to lack of "light." This explanation would certainly be in accord with the facts, as we know them, regarding phantasmal figures.

      12. We are still far from the answer to our question, however: How does spirit act upon matter, and in what way does the spirit manipulate the nervous mechanism of the medium, during the process of communication? Let us now consider this question further.

      Andrew Jackson Davis, in his Great Harmonia, vol. i. pp. 55–65, discussed this problem, and stated that "spirit acts upon the bodily organism anatomically, physiologically, mechanically, chemically, electrically, magnetically, and spiritually." The trouble with such a statement is that it explains nothing (even as elaborated by him), and that it is far easier to believe, e.g., that one part of the body acts chemically and mechanically, etc., upon another part than to suppose that "spirit" has anything to do with the affair whatever. To postulate its activity would be merely to multiply causes without necessity.

      Just here, it might be interesting to inquire what the modern conception is as to the relation of mind and brain—of soul and body; and particularly the question of the "seat" of the soul—that central point which was, until late years, always considered necessary as a fulcrum or point of contact upon which the soul might act.

      The older psychologists and philosophers always took such a "seat" for granted—Descartes, as we know, imagining that the pineal gland occupied that important function. But as the science of psychology progressed, this notion was more and more given up, until the prevailing opinion of late years seems to be that the whole of the cortex is equally the seat of consciousness, and that its total functioning is responsible for the psychical activities which we know under the head of personality or individuality or ego.

      It is interesting to note, however, that Dr. Frederick Peterson, of Columbia University, New York, has lately put forward the theory that there is, or may be, a seat of consciousness, after all! In a striking article in the Journal of Abnormal Psychology (vol. iii. No. 5), he says:—

      "I will say at once that the 'seat' of that power which produces the manifestations of consciousness is in the basal ganglia (probably the corpora striata), and that consciousness is a peculiar summation of energy at that point, capable of being directed, like the rays of a searchlight, into this or that portion of the brain."

      Dr. Peterson then goes on to give some facts which seem to him to support this view. Among these are the phenomena of sleep (the reasons being too long to detail here); the fact that, although every individual brain is stored full of experiences, only a small area is illuminated by consciousness at any one moment; and the phenomena of epilepsy—concerning which Dr. Peterson speaks in the following terms:

      "The one disorder which has led me to think much of this subject is epilepsy, in which disease, loss of consciousness is the most extraordinary and often the only symptom. I allude chiefly to such remarkable conditions as the tic de salaam and the other forms of
