Neurosis Production in Dogs
Is Reported to Psychologists
CANNES Conditioned by Means of Bell
Tones, Society Told by Johns
Hopkins Scientist.

was to fall asleep thus Wiping the
conflict out of the mind.
Extreme Reached in One Case.
This has reached a remarkable ex-
treme, they reported, in one animal.
1t is now six years since he was first
conditioned" Nothing has been
done to reinforce the conditioning.
Yet from seven to nine seconds, with
clocklike regularity, after the bell
originally used as an inhibitory stimu-
lus is sounded the animal is always
fast asleep.
Cats appear to have much more
stable nervous systems than dogs,
| according to similar experiments re-
ported by Dr. Simon DWorking of
McGill University, Montreal. He
placed both animals under similar
conditions producing nervous stress.
Inhibition was easily enough produced
in the cat. he reported. but disap-
peared sooner. The cat proved Curl
ously indifferent to everything out
side the direct problem with which
it was faced. 1t soon escaped by
responding to both positive and hither-
to negative stimuli.
DR.. DWorking found, however, that
| short nervous breakdown could be
| produced in cats through conditioning
to sound stimuli too close together to
| be Disseminated. In several animals
| these breakdowns lasted for three
weeks
Dancing Drug Reported.
| A drug. enthusiastically small guam
/ titles Of which cause mice to dance
so much SO that their dancing can
/ be used as a fine chemical test-was
/ reported by DR.. S. Loewe of Cornell
/ University. The drug is benzedrine,
| commonly used in nose infections.
1t is mixed wit hone of the barbit-
urates, often used in sleeping powders,
and injected into the animals. If
/ there is any benzedrine at all in the
mixture the dancing response is spec
tacular.
| A new instrument for testing the
effect of drugs on blood circulation
| in the brain was demonstrated by
| Drs. James P. Hendrix and Carl F.
Schmidt of the University of Penn
| sylvania. 1t is known as "thermo-
strohmuhr." BY means OF heat re-
actions it measures any increase of
blood in different parts Of the brain.
| The pancreas secretes a hitherto
unknown hormone necessary for pre-
vention of fatty degeneration of
| the liver, it was reported by Drs.
Charles J. Connor and I. L. Chaikoff
of the University of California. They
| found that this condition developed
when the pancreas was removed re-
gardless of how much insulin. the
known pancreatic secretion, was ad-
ministered.
Relief for Angina Pectoris.
Octyl nitrate. drug which re-
lieves the pain of angina pectoris,
was reported by Drs. j. c. Krantz,
jr.; c. Jelleff Carr and Sylvin For
man Of Johns Hopkins University.
1t is used as an inhalant, produces
long relaxation of the blood vessels
Of the heart and is less poisonous in
the blood than other compounds
previously used for the same purpose
DR.. Stephen Karady of McGill Uni
versity reported he had been able tc
prevent surgical shock in animals by
administration daily for week or
more before operation of the very
substance which causes it! This ma
terial is histamine. which is released
from the tissues in large quantities
in serious operations. 1t cuts down
the circulation of the blood. Re-
peated injections accustom the sys-
tenn to its action.
