the sympathetic nervous system were
Of no value to them. If they had to
fend for themselves, he pointed out,
they probably would be at a great dis
advantage. This experiment, it was
pointed out In the discussion following
the paper, may deal a death blow to
the famous James-Lange theory of the
emotions which has long held sway in
psychology.
This theory holds that a man or an
imal facing danger is afraid not because
of the danger, but because of the ad-
justments Of the body to meet the
danger-that Is, that he is afraid be-
cause he runs, and does not run be-
cause he is afraid. With the adjusting
mechanism removed, DR.. Cannon show
ed. the animal Is afraid Just the same.
The operation was performed on mon
keys to find what effect 1t would have
on animals standing erect, such as men,
but the result was the same as with
cats and dogs. .zr+
Study Relation to Fever.
Another important line of study
opened up by this operation, 1t was
pointed out, is on the mechanism of
fever, which has been considered one
OF the protective functions of the SYM
pathetic nervous system -.
In his experiments with Memertian
worms DR.. Coe cut the creatures into
minute pieces, some almost microscopic.
put instead Of dying each bit began to
develop new organs after a few days
ana developed into perfect individual.
Inc only exceptions were with bits cut

the brain, or with bits SO small that
they did not have enough cells to form
nucleus. Some Of these developed into
creatures similar to the young of these
worms, but they did not develop into
adults but soon died.
In each case, DR.. Coe explained, the
fragments preserved perfect polarity In
developing a new animal-that is. the
end OF the fragment which had been
nearest the head Of the original ami
NAL developed the new head. certain
skin cells forming a nucleus of organi-
cation. By cuts which did not COM
pletely sever the body, both lengthwise
and crosswise, he was able to produce
weird creatures with two or three heads
on one body or two or three bodies on
one head.
Found on Atlantic Coast.
The particular animal with which
these operations were performed, DR..
Coe said, abounds along the Atlantic
Coast and Is probably the most remark
able example of the regenerative power
Of living cells in the entire animal
kingdom.
Discovery of a "fatty" acid which
may have far-reaching effect in sci
ence's search for q tuberculosis cure
was reported today.
The acid, chemical substance which
is almost q solid at certain tempera-
lures, induces the growth Of tubercles
when injected into normal animals. II
may be the root Of tuberculosis and a
study Of its formation in human cells
and its activity may provide in a new
angle Of attack against the disease.
The finding is the result of research
in Rockefeller Institute by DR.. Florence
r. Sabin, only woman member of the
academy; DR.. C. A. Doan and DR.. G.
F. Forkner. It was described as one
extensive study of the disease under
taken by the National tuberculosis
Association.
May Find Remedy.
The work centers around the hope
that means Of curing the disease may
be found by studying the chemistry OF
the bacillus which acts as a parasite OF
one Of the cells Of the body.
One part of the study Is to tear apart
the component elements of the cell;
another Is to produce these fractions
in large quantities, and the third is
to show the effect Of each in influencing
the growth of the tubercle bacillus.
The chemical work In connection
with the cooperative study Is being
done in Sterling Laboratory, Yale Uni
versity, by Prof. T. B. johnson and
DR.. r. j. Anderson.
They have investigated the chemical
substances making up the cells. These
have been separated and methods
developed to produce them In large
quantities SO that each may be studied
by itself.
The work of DR.. Sabin and her CO.
workers has been to find the effect OF
the separated substances. One, the
hitherto unknown fatty acid, is OF
such power that doses introduced into
the tissues Of q rabbit easily produce
reactions similar to tuberculosis.
Power Of New Acid.
The newly found acid has the power
of causing rapid multiplication Of one
strain of blood and tissue cells In the
body to the exclusion of all the other
cells of which the hodV In made NO.
