 amplifying as far as possible the fund 

 of well-grounded information gathered 

 to elate, respecting the pathology and 

 prophylaxis of the disease, keeping well 

 in view the principal object of our ini- 

 ciative, which consists in determining 

 by the check of «Tuberculine», applied 

 to the greatest number of catle, at grass, 

 or housed in dairies, the percentage of 

 tuberculosis existent in this country. 



The existence of the disease being 

 suspected or known, through the diag-

 according to the classical system of 

 hypodermic injections; and in some ca- 

 ses by the new proceding called «Oph-

 was slaughtered for anatomical investi- 

 gation, which should confirm the results 

 obtained through «Tuberculine» . 



In this way was obtained the corro- 

 boration of the theory, that the initial 

 lesion most often found in organisms
