among 100000 troops. During the
Worlds War, there were zig deaths
among 100000 troops, but one
death to every 1906 cases, whereas
had the same ratio obtained as during
the Spanish-American War, there
would have been 51,133 deaths, as
against 213, the actual number.
Taking our serum plant test for
determining the viruleney of the hog
cholera virus, and the potency of the
hog cholera serum: 8 pigs are used
2 of them receive virus (the causa-
tive agent of hog cholera) alone, ali
the others receive 2 C. c. of virus
and each pig receives varying
amounts of serum (the protective
AGENT, the hogs that have been re-
ceiving virus alone must sicken, show
visible LESSONS of cholera and die
within certain number of days and
on autopsy show typical cholera
LESSONS. This establishes the viru-
lency of the virus. The hogs that
receive the virus in combination with
the varying amounts of serum, must
all live in order to prove the potency
OF the serum against the virus, the
in fictitious agent. In case that the
hcgs receiving the lesser amount of
serum should sicken. and show visible
LESSONS, it would sbe proof that that
amount of serum was not sufficient,
IN other words the dosage was not
properly balanced. | think that this
experiment is one of the most convinc-
ing to people who are inclined to
doubt the ACCESSIBILITY of the use Of
serums or vaccines. However, tuber-
culin is simply used as a diagnostic
agent in cattle and we are so familiar
with the reaction ATTAINED, or what
DR.. White chooses to call the "sys-
tenn rebelling," that we base cur dag
nosis on this reaction.
90. Every cow is injured more or
less by the injection of tuberculin.
a. A sensitively organized COW is
irreparably damaged by the injection
of tuberculin.
IS. A well animal will react to the
tuberculin test as often as a sick
animal.
"6. Cows fed just enough to keep
them in good condition will very
rarely react to the tuberculin test, but
an over-fed COW will nearly always
react to it.
~ A full-bred COW is more liable
to react to the tuberculin test than
a scrub" cow.
"8. A well animal will always re-
act to an overdose of the serum.
80. The tester can make any COW
react or not, to the tuberculin test.
40. The immunity of an animal is
lessened by the injection of tubercu-
lin.
al. An animal is much more liable
to contract tuberculosis or any Other
disease after having been given Tx
tuberculin test.
IA. If tuberculin itself does mo-
cause tuberculosis, it is at least ar
important factor in causing it.
"15. In direct ratio with the tuber
culin-testing of cows will be the in
crease of tuberculous cows. The in
crease of tuberculous cows in many
states bears out this assertion.
"27. Tuberculin injected into an
animal is very potent factor in
causing the animal to become the
natural habitat for tubercle bacilli.
"34. believe the actual milk-p pro
ducing period of a cow is shortened
at least 50fo by having the COW
tuberculin- tested"
In answering the foregoing pro-
positions, whereas the answer will be
of a general character, | believe it
will be as satisfactory as though each
one were taken specifically: healthy
animals are not injured by the injec-
ton of tuberculin, even temporarily.
therefore COW could not be "irrepar-
ably injured" by the injection of
tuberculin. Animals not suffering
from tuberculosis will not react to
tuberculin. The feeding of animals
has absolutely no bearing on the re-
action that an animal gives to tuber-
culin. We all realize that over-indul.
Gence in food in the human is visited
by bad results and no doubt the same
would apply in the case of animals
The fact that COW is pure-bred
or scrub" does not increase or de-
crease the animals chances of re-
spending to tuberculin, only insofar
as the incidence of tuberculosis is
greater in herds, wherein a large
amount of exchange has been carried
on without regard to the tuberculin
