pending further investigations." He qualifies that somewhat in 

 another sentence by saying that under pecuhar circumstances 

 there may be cases where it would be wise for men to have their 

 animals vaccinated, l)ut his general advice is that it is a little 

 premature at the present time. We are not quite sure enorgh of 

 our ground to advocate the general use of vaccines as a prevent- 

 ive of tuberculosis. 



I want to say in regard to getting rid of tuberculosis that we 

 first have to know that we have it, and a word in regard to the 

 tuberculin test might not be out of place here. The tuberculin 

 test is performed by a great many different individuals under 

 different conditions, and the method of performing it is not 

 entirely uniform, but after all there is a right way to do it and 

 there are probably quite a good many wrong ways. It is well 

 for us to have in mind something near what the right way is. 

 An approved method of performing the test is something like 

 this : In the evening, from 8 to lo o'clock, the temperature of 

 the animals to be tested is taken. If their temperatures are 

 normal or practically so, the tuberculin is injected at that time. 

 For a mature animal weighing about looo pounds, we would 

 inject, of the tuberculin made in this country ready for use, two 

 cubic centimeters ; of the Koch tuberculin, the same amount of 

 the ten per cent solution. For a calf ten days old, about five 

 drops. The dose would vary somewhat with different animals, 

 according to their size. Eight or nine hours after the injection 

 is made, the temperatures of these animals should be taken again, 

 and they should be taken at intervals not exceeding three hours 

 until four temperatures have been taken. Now Dr. Law, Dean 

 of the Veterinary School at Cornell, says the temperature should 

 be taken at intervals of two hours during the day succeeding 

 the injection. Dr. Salmon, Chief of the Bureau of Animal 

 Industry, said that the temperature should be taken from early 

 morning until late at night at intervals of two hours, the day 

 after the injection. Certainly the taking of four temperatures 

 at intervals of three hours is not any too careful work. The 

 objection to the frequent taking of the temperatures, in practice, 

 is that it costs monev. It costs somethinsr to have animals 

 tested anyway, and the cost is sometimes a stumbling block in 

 the way of having the test made at all, and the least trouble
