something that leaves them--a shadow-self. This self can be sent out of
the room--even to a long distance. This self leaves us entirely after
death on the first, second or third day, or so I believe. This is the
force which you would employ to come back to earth--the astral envelope.

PETER. Yes, but what proof have you, Doctor, that I've got an--an astral
envelope.

DR. MACPHERSON. [_Easily_.] De Rochas has actually photographed it by
radio-photography.

PETER. Ha! Ha! Ha! Ho! Ho!

DR. MACPHERSON. Mind you--they couldn't _see_ it when they photographed
it.

PETER. I imagine not. See it? Ho! Ho!

DR. MACPHERSON. It stood a few feet away from the sleeper, and was located
by striking at the air and watching for the corresponding portion of the
sleeper's body to recoil. By pricking a certain part of this shadow-self
with a pin, the cheek of the patient could be made to bleed. The camera
was focussed on this part of the shadow-self for fifteen minutes. The
result was the profile of a head.

PETER. [_After a pause_.] ... You believe that?

DR. MACPHERSON. The experiment has been repeated again and again. Nobody
acquainted with the subject denies it now.
