it alive in considerable quantities.
This leads to the possibility of eventual
vaccination against colds. Such vac
cinations already seem to have proved
effective with chimpanzees, DR.. Dochez
said. but this far have failed to have
any certain effect with human beings.
In the past colds have been sup
posedly due to one or more Of the
numerous forms of bacteria found in
the upper respiratory tracts. and these
have been the basis of the various
anti-cold innoculations which have
proved indifferently successful. 1t is
probable that these bacteria have some
thing to do with a cold DR.. Dochez
said, but his experiments indicate that
they cannot produce one until they
have been activated by the newly found
virus.
Diseases of the heart arteries usually
attack the male sex in early life, ac-
cording to report by Drs Paul D.
White and R. Earle Glendy of Boston.
AS possible influence in development
of this condition, which takes heavy
toll of life every year, they suggested
the stresses Of life in cities, the excess
sive use Of tobacco by boys and faulty
diet.
DR.. John P Peters Of New Haven
told the physicians that the acute
conditions known as toxemias of
pregnancy are not distinct diseases.
but special manifestations Of diseases
of the kidneys and blood vessels.
Women who have these infections sell
dom escape irreparable damage, DR..
Peters concluded after study of 200
cases.. and should not undertake to
bear children.
New Measurement Of Deafness.
DR.. Edmund P. Fowler Of New York
advanced new concept in the
measurement of degrees of deafness.
1t has been customary to measure this
by the ability OF the ear to detect
sounds of the faintest audible in
tensity. 1t was taken for granted
that the ear which could not hear
these was proportionately deficient
for loud sounds. This is not true
DR.. Fowler said, in the condition
known as nerve deafness" Faint
sounds stimulate only few Of the
nerve f1bers which carry impulses to
the central nervous system. When
the stimulus is weak the impulses are
weak and slow. Loud noises increase
the stimulus with the result that both
the number Of fibers acting and the
frequency of the impulses are in
creased
A peculiarly malignant tumor that
occurs in the urinary tract of chill
dren was described by Dr. Meredith F.
Campbell of New York. The only
hope OF lessening the extremely high
mortality in these cases, he said, is to
find and remove the tumors early,
with X-ray treatement before and
after the operation.
Drs. William j. Erickson and Jacob
B. Feldman of Philadelphia reported
study Of the relation of kidney
stones to lack Of vitamin A in the
diet. Deficiency in this diet is known
to produce exaggerated sensitivity to
light. They found the same sensitivity
in persons with stones. Treatment by
adding the vitamin into the diet had
no effect, however, and the investi-
gators concluded that the stones may
not be due to lack of the vitamin,
but to inability Of the body to as
simulate it.
Drs. James T. Priestly and William
F. Braasch of Rochester Mimi, de-
scribed silent kidney stones" which
may exist for years without showing
any symptoms.
New Concept Of Shock.
A new concept Of the mechanism
OF shock, which is supposedly re-
sponsible for at least q quarter Of the
deaths following surgical operations,
was presented in on exhibit by Dr.
Norman F. Freeman Of the University
Of Pennsylvania.
The most notable result Of loss Of
blood or shock from severe pain. cold
