the minutest account of what his father was doing. Mr. Erskine took down what he said, and for three hours the boy, in his trance condition, followed his father through the London streets, and described the various calls he was making on his way. Neither the father nor his son knew anything of Mr.
Erskine's experiment, which was entirely unpremeditated; and the boy, when awakened, knew nothing of the answers he had given.
At this point Mr. Erskine got in touch with the father, and asked him to come round to see him. This is how he describes the interview: "I saw him privately," he says, "and he had rather a shock when at my first question I asked him if he had felt the invisible eye of his son following him. He had not. I showed him what I had written down. He was staggered. For a few moments he did not speak, then he asked for an explanation. I gave it to him. He could not believe it. Then he admitted that his son's account of his movements, of the people he had spoken to, and the scenes described were accurate. Every note I had made was correct to the minutest detail.
"Two promises he asked — and these I readily gave — one that I would never divulge what I had written, the other that I would never send his son's spirit floating after him again.
'Try it with someone else,' he laughed." "Floating after him again"! Is any other deduction possible? To those of us who are acquainted with the Etheric Double, it is not only possible but obvious. The only difficulties for us are —the channel of communication between the boy's spirit and his body, and the picking up of his father's "scent". However, what a bloodhound can do with his nose, the human spirit ought to be able to accomplish with the far more delicate implements at its disposal!
