6. That even by the use of strong disinfecting fluids it is very 

 difficult if not impossible to rid an old stable of the germs of 

 tuberculosis. 



7. That the diagnosis in most cases of this disease by physical 

 examination is impossible. 



8. That in tuberculin we have an exceedingly delicate and re- 

 liable test for tuberculosis. 



9. That tuberculin indicates the existence of tuberculosis in 

 the lungs and other parts of the body when objective symptoms 

 are absent, and when no germs can be discovered by microscopical 

 examination of the mucus from the nostrils. 



10. That its use is not followed by any ill effects of a serious 

 or permanent nature. 



11. That in some instances the injection of tuberculin produces 

 a marked rise of the internal temperature when no tuberculosis 

 exists. 



12. That in some cases when tubercles are present in the body 

 its injection is not followed by a well-defined reaction. 



13. That the reaction following the use of tuberculin bears no 

 relation to the extent or development of the disease. 



14. That it is impossible to formulate a rule by which we can 

 say that certain variations of the temperature may or may not 

 indicate the presence of tubercles. 



15 That in tuberculin we have the only means by which we 

 can eradicate tuberculosis from among our cattle. 



16. That our old-style and unsanitary stables, thoroughly 

 infected with the germs of tuberculosis, make the complete eradi- 

 cation and suppression of this disease well-nigh impossible.
