rge it I had to take it outside the room. I asked the
'operators' (intelligences 'directing things,' apparently, in the
seance-room) if there was any 'power' in the seance-room so far
away from the medium, and they answered in raps that there was. By
'power' I understand them to mean particles of matter taken from
the medium...."

Again, in his _Reality of Psychic Phenomena_, he says:

"I took the electroscope to the table in the corner; then placed it
in the circle near the medium. I asked the operators to touch the
disc of the instrument very gently. They did this almost at once,
the 'touching' consisting of a metallic scraping upon the brass
disc, quite audible, similar in type to the imitation of the floor
being rubbed with sand paper, a phenomenon I quite often observed.

"Result:--On examination, the electroscope was found to be
completely _discharged_!

"I took the electroscope to the table in the corner of the room and
tried to recharge it, but found I was unable to do so even after
repeated trials. Accordingly I asked the 'operators' to put back
into the body of the medium the matter they had taken out (for the
production of the sledge-hammer blows) and to give a few raps when
they had done so. In a minute or two some _very light raps_ were
given, and when I asked if the process was complete I received _no
raps in reply at all_, which seemed to indicate to me that all the
matter used for rapping had been returned to the medium. At any
rate, I found that I could now charge the electroscope; which done,
I placed it on the floor as before within the circle, and asked
that the disc should be touched lightly. After a little time, there
was the metallic scraping as before, and on examination the
electroscope was found to be completely _discharged_."

It will be at once apparent to the reader that two problems confront the
investigator, when once he is called upon to solve such problems as the
above: (1) the _physical miracle_ itself; and (2) the nature of the
_intelligence_, lying behind and directing or controlling the
manifestations. This latter is purely a _psychological_ question, which,
immensely important as it is intrinsically, does not enter into the
_physical_ problem. It need only be said that this is _the_ baffling
question in psychical investigation, and the most puzzl
