6. The next day, at 6 A. M., commence taking temperatures, and con- 
tinue every two or three hours until the twentieth hour after injection, 
at which time if there is no tendency for ihe temperature to rise the 
test may cease. 
7. A rise of two or more degrees Fahrenheit ahove the maximum tem- 
perature observed on the previous day, providing this temperature ex- 
ceeds 103.8° P., should be regarded as an indication of tuberculosis. 
Those cases which approximate but do not reach this standard should 
be considered as suspicious and held for a retest six weeks later, giving 
double the original dose. 
TREATMENT OF TUBEKCULOSIS. 
Treatment of the disease is not seriously considered by any authori- 
ties at the present time. 
The measures to be adopted to prevent the spreading of the disease 
must, take into consideration not only the tubercle bacillus, but likewise 
all those circumstances which make cattle more susceptible to the disease 
which have already been dwelt upon. It would be useless to repeat here 
all that has been said above on the transmission of tubercle bacilli from 
one animal to another, and on the dangers of certain debilitating influ- 
ences. A careful study of these will show how tuberculosis may, at least 
in some cases, be prevented. Great care should be bestowed upon the 
breeding, the surroundings, and the food of the animal, so that the latter 
may be put into a condition to resist infection even when exposed to it. 
A tuberculin test should be applied to all strange cattle before they are 
introduced into the herd, and those which show a reaction should be re- 
fused. 
A rigid exclusion of tuberculous animals is all that is. necessary to pre- 
vent the appearance of the disease, provided cattle are not infected by 
consumptive persons and animals, though it is probably unusual, be- 
cause the bacilli from man are, in the majority of cases, attenuated and 
harmless for cattle. 
Tuberculosis in cattle must also be considered as bearing upon tuber- 
culosis of other domesticated animals, particularly hogs. In Europe 
and the United States this disease is not so uncommon among hogs, and 
appears to be on the increase. The reason for its existence may be 
looked for in the feeding of pigs with skim milk, buttermilk, and whey 
in dairies, with the offal of the abattoirs, behind tuberculous cattle, and 
the household refuse generally. If tuberculosis is common among cattle 
it is likely to be transmitted to hogs kept in this v/ay. 
The carcasses of animals which have died of tuberculosis should be 
buried deeply so that they can not be eaten by other animals. This 
is likewise true of all organs or tissues of slaughtered animals con- 
taining tubercles. These should never be fed to other animals, such as 
licgs, dogs, and cats, and should either be destroyed by fire or deeply 
buried. 
When any of the animals in a herd of cattle show evident symptoms 
of tuberculosis, or when they are proved to be affected with this disease 
by the tuberculin test, the best method of procedure in most cases is to
