when reduced to an invisible thread of vapour, it seems just as competent to control and to retrieve the wandering phantom. That would seem to be the most remarkable achievement in the whole business. Mr. Muldoon describes the thickness of the cable, when the etheric and physical bodies are side by side, as having the diameter of a silver dollar, though, owing to the surrounding aura, it gives the impression of being about six inches through. He calls the distance between the physical body and the point at which the cord reaches its minimum thickness the range of cord activity", an interval which may vary from eight to fifteen feet. Beyond this it seems capable of indefinite extension, and the h rojector ceases to be conscious of it unless something untoward appens, or he thoughtlessly yields to an emotional impulse. Also any shock or surprise will bring the Etheric back into "coincidence", and when this is violent the physical body receives a blow, especially if the distance travelled is great and the return precipitate. Again, a common cause of bodily repercussion is the awakening to consciousness following unconscious projection in sleep. The consciousness returns, or seems to return, before the Etheric is re-established in the physical. "When thrust back into coincidence in this manner," says Mr. Muldoon, "the entire physical mechanism is jolted throughout—as though every muscle in the body contracted at the same moment—and the body gives a spasmodic jerk, more noticeable in the limbs than elsewhere." Most people have experienced this jerk, on a small scale,
