lyS TUBERCULIN TEST 



June 11. Inoculated male guinea-pig (No. 19) with 4 cubic centi- 

 metres of milk from Pilot's Lily. Sample used from morning's 

 milk. 



June 15. Inoculated female guinea-pig (No. 20) with 4 cubic cen- 

 timetres of milk from Pilot's Lily. Sample used from morning's 

 milk. 



After a sufficient length of time had elasped for the disease 

 to develop, the inoculated pigs were examined ; the autopsy 

 failed to show any case of tuberculosis. 



Two calves were fed for about three months with the milk 

 of the condemned cows. When subsequently tested with tu- 

 berculin, they showed no evidence of the disease. 



Nunierous samples of the milk of the condemned cows were 

 examined microscopically but no bacilli were found. 



SUMMARY 



Eight animals, 14^ per cent, of the herd of fifty-five, were, 

 by the tuberculin test, pronounced tuberculous. 



Four months later two new cases were found ; nine months 

 later still another case was found. This shows the advisability 

 of testing a herd at least once a year. 



All of the animals whose final test showed a reaction were 

 at the autopsy found to have the disease. 



One condemned animal apparently recovered. 



No evidence of the presence of the bacilli in the milk of 

 the tuberculous cows was found. 



Closi7ig Word 



In the very active campaign against tuberculosis, of a few 

 years ago, excessive and unwise measures may have been rec- 

 ommended and used ; and it may be that too great indiffer- 

 ence has followed. The fact should not be lost sight of, 

 however, that tuberculosis is a very serious disease, causing 

 great loss among domestic cattle, and to a certain extent en- 

 dangering human life. Continuous, united, and intelligently 

 directed effort should be made to check its ravages.
