instruments, which have been
employed in novel ways

Tor this purpose, connected with p Wheat
stone bridge and connected to the medium, bv
TWO electrodes, covered with sponges which
nave been molstened with salt and water
n galvanometer is an instrument which reg
listers slight changes in electric current1 IF
any emotion is aroused in the subject this will
cause the resistance offered by the body to the
electric current to vary, and more current will
pass through the subjects body as the emo
ton is aroused. This variation of current is
shown in the galvanometer. A small mirror
swings to the right left as the current
varies, and this be observed through
slit, through which the observer looks or it
can be caused to reflect beam of light on the
opposite wall, which will travel over scale
drawn upon the wall. so that a very slight
movement of the mirror will cause large
variation the scale at distance.
This has been employed in the past to test
emotions, and has been applied in criminal in
vestigations to test the emotional reactions
Of the subject when asked certain questions
in court.
1t can be applied in psychic investigation in
this way. A list Of words is read to the
medium when in the normal state. Emotional
reactions will be noted to certain words, which
reported
Now, when the medium goes into trance
and spirit claims to be talking through
her, the question is: Is this a real spirit or
only part of the sub-conscious mind of the
medium? Hitherto it has been impossible to
prove this by any objective test.
The instrument however, shows it in the
following manner:
If the trance personality, claiming to be
spirit reacts en1otonally to the same words
as those to which the medium reacted, we have
proof that we are dealing with the same mind
that is, the medium. If, on the contrary, we
obtain emotional reactions to different words,
we have proof that we are dealing with diff
ferent mind-either "spirit" (as the intelll-
gence claims to be} absolutely water
tight compartment in the mediums sub-con-
scious mind which reacts to different words
than the mediums normal mind. Hitherto in
vestigations have failed to show the existence
of any such water-tight compartment, in cases
Of hypnotis1n multiple personality, etc.. which
show emotional reactions of totally different
kind from those exhibited from the normal
personality Of the medium. Experiments in
this direction are now being undertaken, and
it seems fairly clear that, If successful, they
would prove the reality of some alien mind
different from that of the medium herself
