gravity of the human BODY when

center fell or not. and, if it rose or
fell, to estimate how great an amount
of blood was sent to any given portion

mental exercise, by muscular labor or
thought.
| In trying to solve these problems
DR.. Adams has placed more than $50
| undergraduates on his musclebed. The
subject is placed PROSTATE on table,
/ balanced by compensating weights.
The man, lying PROSTATE, can be rolled
in any direction by a large or fine
adjustment Levels, graduated scales,
and an indicator for use in making
records form part of the apparatus.
The bed rests on very Acknowledgements

| DIR. Anderson places on the table a
subject, balances him exactly, and
then tells him to answer some ques-
ton which requires considerable
thought Although the student does
not move muscle, the rush of blood
to his head, caused by his mental
labor in thinking, causes the center of
gravity to change. The subject is no
longer balanced. His center of gravity
has risen owing to the presence OF the
greater amount of blood. To show the
extent to which the center of gravity
will rise in cases of this kind, DIR.
Anderson says that he examined sew
eral students before and then after
they had taken their annual examina-
| tons in their studies. He found that
under the stress of such conditions the
center of gravity had risen from to
| 16 millimeters, or from one-sixteenth
| to 21a inches. Little wonder that
apopleXy or brain disease of some kind
follows continued mental strain when
such an amount of extra blood Is
forced to the brain. as is proved to be
done in such cases as these.
DR.. Anderson has carried out his
| experiments by working from the OPP
posite side of the question. He tried
physical experiments to show that by
exercise the blood supply is called
| from the brain and taken to the lower
, extremities. The tests were uniformly
successful, the center of gravity being
tremendously lowered by the exercises
taken. A unique feature introduced by
Dr. Anderson into this line of expert
mentation was for his subject to
think out" the gymnastic exercises.
instead of actually going through
them. Although the athlete did not
move a muscle, the effect proved to be
much the same, the blood rushing
away from the head to the lower ex-
tremities. When the deductions made
from these experiments are applied to
medical problems affecting brain dis
orders, discoveries OF revolutionary
nature are expected. squad of ath-
letes were examined who tried phys
ical exercises in a mechanical manner
and another who were given exercises
which they took special delight in
doing. Without exception the tests
showed that the center of gravity
changed slowly when the exercises
were performed listlessly, while in the
case of the others the blood eupply to
the legs and arms was rapidly in
creased and the center of gravity
changed several inches. Another set
of athletes was set at work perform
ing exercises while seated and made
to carry out the same set while stand
ing.
In the cases of every man who exer-
cised the center of gravity arose
higher while he was sitting than
standing. Another test was taken of
number of gymnasts who exercised be-
fore a lookingglass and then did the
same set of exercises away from the
glass 1t was clearly demonstrated
that the center of gravity arose more
rapidly In cases where the exercises
were taken in front of the glass than
those when they were not.
