thin white connective-tissue capsule. Otherwise the udder 

 showed no lesions. 



The cheesy foci showed fine acid- fast rods (tubercle 

 bacilli). 



3. Tuberculosis of the left posterior quarter with ulcera- 

 tion through the skin and complication with gangrene. Ad- 

 vanced tuberculosis with softening of the caseous foci. 



The left posterior quarter was greatly swollen and hard. 

 Posterior to and on either side of the teat there were two 

 fistulous openings about the size of a pencil containing a 

 yellow, stinking fluid. 



The corresponding lymph-gland was greatly swollen.

 and the severely diseased area a yellowish-gray, irregular, 

 granular line of demarcation was visible. A few yellow,
