At the present time there are many different brands of tuberculin (each 
of which possesses its own particular properties) obtainable from various com- 
mercial agents in each of the colonies; but it is specially recommended that, in 
order to obtain uniform results, only that tuberculin should be used which is 
prepared and supplied by the Stock Institute: precisely on the same lines that 
in Germany only Koch’s tuberculin is used; while in Denmark the Government 
will only allow that to be used which is prepared under the direction of Pro- 
fessor Bang, at Copenhagen ; and in the United States the Government 
specially recommend that prepared in the Laboratory of the Agricultural 
Department. 
The overwhelming evidence collected in different countries throughout the 
world has shown that the use of tuberculin as an aid to the diagnosis of 
tuberculosis in cattle is one of the most brilliant discoveries of the nineteenth 
century, and, as time passes, its real value and significance will be more and 
more appreciated by the masses of mankind. 
Now that this test has proved itself to be almost infallible, it should be 
the desire of every person interested in cattle to commence at once in a. 
judicious and systematic manner and eliminate from his herd, with the least 
ossible loss, every tuberculous animal, not forgetting the obligations to the 
public both in the exchange and sale of live stock and products, both of which 
should be guaranteed free from tubercular taint. At the same time special 
attention should be directed to the preservation of certain strains of well- 
known and productive blood, which have taken many years of intelligent 
thought and careful study by the most observant minds to bring up to their 
present high standard of perfection. 
The following is the method, based on the practical experience of such 
keen observers and eminent scientists as Professor Bang, of Copenhagen, Pro- 
fessor McFadyean, of London, and Dr. Salmon, of Washington, I have 
adopted for the eradication by tuberculosis from the dairy herd at the island of 
St. Helena :— 3 
T. All animals showing outward signs of disease should be immediately 
killed and the carcasses destroyed by fire. 
_ II. The remainder of the herd tested with tuberculin every six months. 
TIT. All animals of little value, such as old cows or bulls and very young 
calves that have shown evident reaction to the test are carefully 
slaughtered and examined, and the whole carcass thoroughly boiled 
down as food for the pigs.
