TENTATIVE CONCLUSIONS. 



1. Tuberculin is the best diagnostic known for tuberculosis. 



2. Tuberculin itself may be infallible, but its application and interpre- 

 tation are not. 



.'?. An arbitrary point of condemnation is unwarranted. 



4. To succeed in eradicating tuberculosis from a herd, the tuberculin 

 test must be applied persistently at intervals for as yet an undetermined 

 time. 



5. The slaughtering of animals reacting to tuberculin is not justified, 

 unless the physical condition of the animal confirms the tuberculin test 

 and makes it a wise precaution. [Reacting animals should be isolated.] 

 Should a second test diagnose tuberculosis, slaughter is possibly made 

 justifiable unless the animal is sufficiently valuable to isolate for her off- 

 spring or in hopes of recovery. 



I wish to acknowledge my great indebtedness to Prof. E. A. A. Grange 

 for the most important part he has occupied in this bulletin and for his 

 timely suggestions.
