DISEASES AND TREATMENT OF CATTLE 431 
If affecting the brain or spinal cord it causes paralysis, 
and death soon follows. If any of the other parts or organs 
of the body are affected it causes symptoms peculiar to that 
organ, and the animal slowly pines away and dies. 
To find out whether cattle are affected with tuberculosis 
use the tuberculine test. 
The Tuberculine Test. — A day previous to applying the 
test take the temperature. If normal this should be from 99° 
to 101°. Keep those to be tested in a shed or stable free from 
drafts, feed regularly and do not allow large drinks of cold 
water at a time. Fifty minims of tuberculine is a dose for 
an ordinary sized cow ; this, however, must be regulated to 
the size of the animal. See that the tuberculine is fresh and 
kept in a cool place. 
Choose a point on the neck. Wash the skin at this point 
perfectly clean with warm water and soap. With a hypo 
dermic syringe — thoroughly cleaned and disinfected — inject 
fifty minims (drops) of tuberculine under the skin. Follow- 
ing the injection take the temperature three times — at the 
end of the ninth, the twelfth, and the fifteenth hours. 
Should the temperature gradually rise to 104° or higher 
it may be concluded that the animal is suffering from tuber- 
culosis. 
Should the temperature rise only to a point less than 103'' 
the conclusion is that the animal is not tuberculous. 
On the other hand, if the temperature rises to a point 
between 103° and 104** the case is considered doubtful and 
the test should be repeated. 
As soon as it is known that the disease exists the animal 
should be destroyed in order to prevent others from becom- 
ing affected. Not only this, but the disease may be com- 
municated from cattle to man through the milk or by eating 
the meat. 
When opening cattle the organ that is affected will be 
found to be eaten away with the disease, and its place is 
taken by a lot of small lumps inclosed in a membrane. If 
you cut into them they are found to be full of other little 
cheesy lumps about the size of a pea. In very bad cases 
tumors will sometimes form and be full of yellow matter.

This disease originates spontaneously in dog^ and cats 
attid can be communicated to other animals or man by the
