Necropsy: Weight 643 pounds; fair condition. The lesions of tuber- 

 culosis found in this animal were as follows: At the lower border 

 of the middle lobe of the right lung was a slightly depressed area 

 about one-half inch in diameter containing a collection of thick yel- 

 low pus filling a cavity the size of a large pea. The walls of this 

 cavity are on-eighth of an inch thick, white, and of firm, dense text- 

 ure. In one of the left peribronchial glands there is a caseocal- 

 careous nodule about the size of a pea and having the appearance 

 of a wholly closed process. Guinea-pigs inoculated from the lesion 

 in the lung became tuberculosis.
