6. Failure to react after the first injec-
ton may indicate either recovery or an a.

and fail to react under certain conditions.

the animals remained excellent throughout
the experiment. There was no loss Of con-
dition in any case, and In several decided

Indifferent care which was purposely given.
8. Tuberculin may have distinctly cura-
tive effect in cases of recent infection and
where the LESSONS are limited In extent and
may increase the tendency toward recovery
in other cases. The cases, Rose and "L No.
q made two evident recoverfes out of a
total Of eleven treated and two, Fancy Sec
ond and Polly showed evidence of recent
repair in diseased tissues.
Here then, were two recoveries, and pos
sibly third. out of eleven cases treated
during the whole period, and treated under
such ether circumstances of food and care as
preclude the probability of the recoveries be-
ing favored by the conditions under which
the animals were kept.
1t is interesting to note In the summary
OF this experiment that two animals recovered
during the course of treatment, and two 9TH
ers were evidently benefited by the treatment
In spite of the intentionally imposed unfayor-
able conditions of feed ad care.
DR.. Reynolds takes the ground IN this bull
letin that sanitarians should not be too hasty
or radical; that sweeping measures may be
more nearly the ideal thing, but are not apt
under present conditions, to be practical, and
illustrates by actual figures how impractical
would be any sweeping plan that would aim
toward discriminating tuberculosis from the
United States, or even from a single state
by any universal process or testing and kill
ing. 1t would require very large number
and would require such an enor-
nous amount of tubercunn that enough
could not be obtained for the work; that the
expense for testing would pc enormous and
not to be thought of in the present condition
Of financial depression.
The plan outlined In this bulletin for
dealing with this matter suggests that the
city diaries, and all diaries that supply milk
for consumption, should be tested first, and
urges that every animal tested should be
tagged, or permanently marked sound
or "tuburculous," that all inspection should
be done by the men having especial training
for this kind of work, and not by politicians;
that the inspection should include an estimate
OF air spec per COW; raridity of ventilation
changes, light with especial regard for sun
shine, disposal Of manure and 1other refuse
kind and quality of food and, water and a
study Of how the milk is handled.
DR.. Reynolds argues vigorously in this bull
letin that the plan of keeping cows in stables
so continuously as done By many dairymen
is not in accordance with the plain teachings
of animal physiology and the, evident results
OF such practice clearly emphasize the great
law Of animal life-that use begets strength
and idleness begets disease.
No animal can long remain healthy with
out a reasonable amount of exercise sun
shine and air. When lions. Gti9ers and mon
Keys are shut up in cages they become tu-
Derculous' and when dairy .'eows are shut up
In stables in violation Of this principle, they
become tuberculous, and they also become
susceptible to other diseases that impair their
usefulness as human food 'givers.
1t is one of natures laws that organs which
are not used. or are used less than nature
INTENDED they should be, lose strength; lose
sorbed or diseased. and a cows lungs can
not reasonably be expected to prove an ex-
ception. Generation after generation they
must lose in size. in expansion power and
in tissue nutrition why should thew not be-
come tuberculous?
Certainly the COW can produce the quarts
OF milk and pounds of butter with the few
est cents Of cost when she stands still be-
cause so little Of the food consumed is used
for food OF support and so large proportion
appears as food of production; but the break
see how this will affect the vitality and
breeding energy of the offspring generations
hence. 1859
After the city dairyman DR.. Reynolds would
begin with the breeders and try to show
them that their own interests are in the way
OF eradication: that natures laws are I'M
changeable; that the great laws of physiology
and heredityv will never be varied that
breeders may acquire for their, cattle fancy
muzzles or belts Of color around the body
and the man who is founding a herd should
be very sure he is not founding a herd on
tuberculous stock. r.
DR.. Reynolds suggests that 1t is not nee
essary to kin all animals that react on tuber-
culin test, and that under certain circum-
stances some may be valuable for breeding
purposes. t@ ~
A large percentage Of cows that react are
plainly in vigorous general health and the
tuDercuhr LESSONS are plainly local.
The present discussion concerning the TYNE
OF tuberculosis form. and general appear
ance is mere nonsense for the great major
1ty OF all cows that have been condemned as
tuoereulous by the test, and have been
proven TO be so on post-mortem have
been such as no man would ordinarily have
selected as being so diseased.
