over and over again, without the least
emotional reaction.
A particularly vicious form OF ab-
dominA cancer induced in rats for
mixing In their food daily over a
period OF two months OF wheat germ
oil, the most common source Of vita
min E, which is in wide use as
preventative OF sterility, was shown
physicians here today by L. 9. Rown-
tree, John Lansbury and Arthur Stein
berg OF the Philadelphia General
Hospital.
For some years Dr. Rowntree and
his associates have experimental with
the remarkable growth induced in
rats by feeding extracts Of the thymus
gland at the base of the neck. There
was reason to believe that some of
the vitimins might be concerned in
this growth, which is progressively
accelerated from generation to GEN
GRAFTON until rats attain their full
growth In three or four DAYS.
Appearance Of Cancer Unexpected.
The appearance Of the cancer with
the vitamin E preparation was entirely
unexpected. The abnormal growths
could be removed transplanted into
other rats, and keep on growing.
They are among the worst forms OF
cancer known to science. The Phila-
delphia doctors warned that their re-
suits are entirely in rats and there is
no reason to believe, from present
evidence. that overdoses of wheat germ
on may have the same effects in
human beings. The cancers were pro-
duced, they stress, with unrefned
wheat germ oil. They have been un-
able to duplicate the results with re-
nned products obtained from pharma-
ceutlcal houses. The significant re-
suit, they say. IS the evidence that a
vegetable product contains something
which will produce cancer. Hitherto
1t has been possible to produce artifi-
clal cancers only with certain tar
derivatives.
Location of the brain site of a sixth
sense. that Of location in space, WAS
reported in an exhibit arranged by
Drs. E. A. Spiegel and Mona Spiegel-
Adolph OF Temple University, Phila-
delphia, and DR.. Norman P. Scala of
Georgetown University Medical School.
May Relieve Seasickness.
The experiments in which the Wash
lngton doctor participated not only
throw new light on the physiology OF
the brain and autonomic nervous sys-
tenn but may lead to practical meas
ures for relief OF seasickness. dizziness
on a merry-go-round, etc. The sense
organ OF this sixth sense" it was ex
planned, is the labyrinth Of the inner
ear. When this Is stimulated, either
by rotary or rocking motion, or by
an electric current or cold water. a
feeling OF vertigo results. BY special
instruments the experimenters have
found just what happens. First there
Is connection between the labyrinth
and center in the medulla oblonRata
at the base OF the brain. This center
k inhibited. causing = relaxation of
blood vessels throughout the body and
lowering Of blood pressure. At the
same time the center of the vapus
nerve In the medulla is stimulated
resulting IN increased movements of
the stomach. This Is responsible for
the upset stomachs so common in sea-
sickness. With the causes known, DR..
spiegel said, various drugs can be
administered to stimulate the yaso-
motor and inhibit the vasus center.
The best system, he believes, il to
lay nat on ones back In a boat, thus
assuring good blood supply to the
brain.
The brain center Of this sixth sense
long has been In dispute among physi-
ologists. DR.. Spiegel and his asso-
ciates studied large number of cases
Of perpetual sesSickness" due to
tumors OF the brain. They found
that the most common site Of these
was in the temporal lobe, Just over
the ears, In which also Ii located the
center Of hearing. The most active
point for the production Of vertigo
seems to be about At the junction of
the temporal and parietal lobes.
Represented in Cerebral Cortex.
They find further proof that this
sixth sense 10 represented in the cere-
bral cortex Of the brain in the fact that
conditioned refiexes can be estab-
lished in dogs held in various posi-
tions on fitting table and that the
now familiar brain waves, known to
be entirely confined to the cortex. can
be extinguished by stimulating the
ear labarynth.
Discovery of . new hormone in the
pancreas, lack Of which apparently is
responsible for fatty infiltration Of
the liver WAS reported by Drs. Lester
r. Dragstedt and John Van Prohaska
of the University Of Chicago.
1t long has been know that animals
from which the pancreas Is removed
could not live, but this was supposed
to be due to the other hormone Sc
cretsd from this organ, the WELL
known insulin. It was found, how
ever, that even with plentiful injec-
tions Of insulin the animals died and
that the curious liver condition, which
sometimes is found in human beings,
was . constant phenomenon.
An extract Of the pancreas has been
prepared which prevents this. Known
