NINTH ANNUAL YEAR BOOK— PART X 477 
All tuberculous animals should be slaughtered in abattoirs having 
federal inspection, and the money obtatined from carcasses which are 
inspected and passed for food, and from the hide and offal of those car- 
casses condemned as unfit for food, should be applied as part payment on 
the indemnity for their respective owners. The payment of indemnity for 
their respective owners. The payment of indemnity for tuberculous ani- 
mals is a good business policy and would do more toward making the 
tuberculin test popular with cattle owners than any other possible action. 
And as a corollary of the latter more testing would be performed, and 
more tuberculous cattle would be discovered at the start, but the gradual 
suppression of the disease would soon be manifest, as has been noted in 
Pennsylvania and Denmark. Furthermore, as Stiles has mentioned, if 
tuberculosis can be eradicated from dairy herds with but slight loss to 
the owner, the increase in the price of milk would naturally be inhibited, 
and the children of poor families would consequently be in less danger 
of having this very important article of their diet decreased. 
From the investigations and observations that have been mentioned it 
may be safely concluded: 
1. That the tuberculin test is a wonderfully accurate method of de- 
termining v\^hether an animal is affected with tuberculosis. 
2. That by the use of tuberculin the animals diseased with tubercu- 
losis may be detected and removed from the herd, thereby eradicating the 
disease. 
3. That tuberculin has no injurious effect upon healthy cattle. 
4. That the comparatively small number of cattle which have aborted, 
suffered in health, or fallen off in condition after the tuberculin test 
were either diseased before the test was made or were affected by some 
cause other than the tuberculin. 
SUMMAEY OF DIRECTIONS FOR MAKING THE TUBERCULIN TEST. 
1. Stable cattle under usual conditions and among usual surround- 
ings, feed and v/ater in the customary manner. 
2. Make a physical examination of each animal, and give to each one 
some designation by which the animal will be known throughout the test. 
3. Take each animal's temperature at least three times at two or three 
hour intervals on the day of injection; for instance, at 2, 5, and 8 P. M. 
4. At 8 or 10 P. M. inject a dose of tuberculin under the skin in the 
region of the shoulder, using a sterile hypodermic syringe after disin- 
fecting the skin at the seat of injection with a 5 per cent solution of 
carbolic acid or a similar antiseptic solution. 
5. Tuberculin is not always concentrated to the same degree and there- 
fore the dose, which should always appear on the label, varies consid- 
erably. The dose of imported tuberculin is 0.2.5 c. c. for an adult cow, 
and before injection is diluted with sterile water to 2 c. c. The tubercu- 
lin made by the Bureau of Animal Industry is prepared so that it will 
not be necessary to dilute it, and the dose is 2 c. c. for an adult animal.
