PREFACE. 43 capital M and inverted commas, to denote the body which remains at home, and which is apparently fully conscious, normal, and in no way entranced.” The phenomenon of mental-body-travelling is familiar to many; but I do not remember ever having seen the process explained so clearly as in the following passage :— “In the mental-body-travelling the ‘1’ appears to leave the ‘ Me,’ and to fly through space at a velocity that renders the view of the country passed over very indistinct and blurred. The ‘I’ appears to be about two miles above the earth, and can only barely distinguish water from land, or forest from city ; and only then, if the tracts perceived be fairly large in area. Small rivers or villages would not be distinguishable.” Mr. Turvey is able to produce actual physical effects with his mental body, but only when he is able to draw energy from some physical body in the room. He says— “When, besides hearing—or seeing—with the ‘mental’ body—‘ I’ also moves matter, then ‘I’ makes use of a medium’s ‘psychic force,’ which ‘I’ appears to draw from the medium's wrists or knees as a sort of red sticky matter (a part of his ‘energy’ or ‘vitality’ body ?).
