 efl'ective step toward rational treatment. 



The greater part of the energy and resources of the laboratory 

 have been devoted during tlie past year, to the study of immuniza- 

 tion of cattle against tuberculosis. This work was started some 

 years ago, and has been reported upon in part by Dr. S. H. Gilli-

 Our work has been amplified and, as will be shown in another part 

 of this report, it has been placed on such a basis as to be tested 

 under practical farm conditions.

Section L*. If it shall be found that the animal, from which the 

 carcass or meat came, was infected with tuberculosis, or other 

 infectious disease, and to a degree that renders the flesh unfit for

 demned, and shall be disposed of by the use of any method that
