e actual experiments were begun,"both
ere briefed concerning-the various ppssi ilities
p'resentecfin the use of telephone administered SI� control. The
discussion also involved the essential work of attempting to Obtain
"normal" appearance for operation activity. After considerable
discussion, the following tests were run off:
ermine basically whether or no
could be placed in the state of d�SI.and then con-
itioned t ctt in "normal" maxmer.,both girls were sent to the
M2tensio room of Each girl' in turn was called
on the e ephone and placed in adeep trance state with instructions
to maintain "normal" appearance. In each case, the other girl acted
as an observer, sitting opposite the girl receiving the telephone
call. Each girl was then called on the telephone and placed in a
deep trance state and instucted to maintain "norraal'sappearance,
each was instructed to return to the Operations Room, bringing the
other girl with them. Both girls complied precisely and based upon
nearly "normal". and the writer listening on the tele-
phone own observa � their manner and appearance was very
phone during the Inductions and wei.-e able to detect only a very-
slight loss of volume in the voice of the subject during the pro-
ceedings; otherwise, there was no apparent change in� the� conver-
sation. This test was regarded as successful.
The second test involved a more complex method as follows:
Each girl was placed in a deep SI state in the Operations Room.
While under this control, they were told that after they were

and from there they would receiv e ep one call from an individual
who would be a friend of theirs (fictitious names, of course, were
used at this point). This individual would carry on a normal con-
versation with the girl and introduce a code word during the con-
versation. At this point, the subject wOuld then pass from an "awake"
state to a state of deep SI without CHanging expression and appearing
at all times perfectly "normal". ,Thereafter, the girls were instructed
to return to the Operations Room and upon seating themselves on the
sofa, to immediately go into a complete sleep state. -Again, in-each-----
case, each girl acted as an-Observer for the other .girl. This test
was completely successful The girls were called on the telephone
by the fictitious person and carried on a conversation. During the
conversation, the code wordwas nentioned and, in each case, the
girl receiving the telephone call, passed from an "awake" state to
.a complete deep trance state, imintaining their eyes open and ap-
pearing "normal" throughout the conversation. Each girl reported
that the transition was completely perfect and w.ould certainly de-
ceive anyone unless that person was specifically observing the
r minute changes as the trance state was induced. Both
and the writer again detected a minute change in the
volume of the voice of the subject receiving the call, but no in-
terruption whatsoever to the general conversation was noticed.
The girls were watched as they moved 4 froM. oom to the 411111F Operations Room and, for a matter of record, the r w ng,
expression, etc. was perfectly normal. Each girl, in turn, upon
completion of the test and returning the the Operations Room, im-
mediately passed into a deep state of sleep. The test has consider-
able operational value since anyone using the code word or code
-could take control of a thoroughly SI conditioned subject. Fur-
thermore, to the casual observer or individuallabout'the subject','-.
being so induced, it would be impossible to note that a transition
had taken place.
In connection with the above, and to lay, groundwork for the
�evenin ssary to ascertain whether
or not der completeSI control,
could m morige a safe combination, go to a safe, open same, and
return to Operations Room under SI ontrol. This test was then
tried with each subject. who has had considerable -
experience in opening our Iuree_waymales, opened the safe.with-
ut anvnrohl m and completed the experiment without difficulty.
owever, only being instructed a few days pre-
NUCUS y and o y.having opened a safe-two or three times before,

that, if trained to open the safe, she could have easily opened
it without difficulty.

SI control would have been impossible to detect by an one. In- ,. -
' dition, it should be remembered that some ,tdalle ago,
