Axitopsy made October 24, 1892. 



Just underneath the skin of the patella region there was found a 

 small abscess containing creamy pus. About the articulation there 

 was a large amount of fibrous tissue, in the center of which there 

 appeared a nodular growth about the size of a hen's egg, this con- 

 tained in its center caseous material. The synovial membrane was 

 roughened and in many places covered with small diffuse growths. 

 The articular surface of the bone was normal. In some parts of the 

 abdominal cavity small single tubercular nodules were found. The 

 lungs contained many tubercles varying in size from a small shot to 

 a large orange. The inferior portion of the surface of the lungs and 

 walls of the thorax were thickly studded wilh new growths. 



Case No. 2 was th.it of a pure blood Ayrshire cow, nine to ten 

 years old. She had been owned and kept in the college barn for 

 years, and had stood in the stall nearest the doors at the southeast 

 corner of the stable. This animal at the time of the test was dry and 

 fat, ready for the butcher and so far as known perfectl}' free from 

 tuberculosis. 



Autopsy, Nov. 22, 1892. 

 No evidence of disease found in any part of the bod}' except eight 

 or ten very small tubercles in the lungs, none of which were larger 

 than a small pea. These were well distributed throughout the lung 

 tissue and were below the surface, none being found directly beneath 

 the pleura pulmonalis.
