No. 7. — The picture of the bull was taken nearly four years after he was 

 known to be tuberculous and three years after it was known that 

 he was passing tuberculosis germs from his body. 

 Directly after his picture was taken he was killed, and in addition 

 to numerous nodules of tuberculosis in his lungs it was found, when 

 his body was opened, that nearly all the lymph glands connected with 

 his bowels and liver were diseased. At the time of his death the 

 bull weighed 1,850 lbs., and his apparent condition Is excellent for 

 an animal that was fed only rough forage and no grain In any form. 

 The presence of tuberculosis In his body would never have been 

 suspected before his death without the help of the tuberculin test
