AGRICULTURAL EXPERIMENT STATION. 61 



Station Council, and then she was killed. In the mean time her 

 appetite was irregular and she continually lost flesh and became 

 weaker. Her temperature was taken frequently and varied from 

 101° to 105°. 



When killed, her left lung was found adherent over a large part 

 of its area and contained a large abscess with a capacity of nearly 

 two quarts. Attached to the surface, and particularly within the 

 substance of this lung, were many tubercles, varying from the size 

 of a pea to that of a large goose egg. The right lung had a few 

 small tubercles in its substance, but no abscesses. Attached to 

 its inferior and posterior borders, also to the walls of the thorax 

 and the right side, were many tubercles, most of them small. In 

 the right thoraric cavity attached to the diaphragm was a mass of 

 tubercles weighing over a pound. Many of the thoraric lymphatic 

 glands were enlarged, and one of them contained an abscess of 

 considerable size. The liver contained a number of small absces- 

 ses and had a few tubercules attached to its surface. 



When this heifer was found to have tuberculosis, her dam Sard 

 4th was carefully examined and although up to this time she was 

 considered perfectly sound and was in apparently fine condition, 

 the examination revealed a little trouble in the left lung. When 

 the heifer was killed and her condition ascertained, the Cattle 

 Commissioners were notified as required by law, and two of the 

 commissioners, Dr. Bailey and Mr. Beal, came here. At this 

 visit they only examined Sard 4th, and they pronounced her 

 diseased. November 10th, they came again to examine the rest 

 of the herd. 



At this second visit they examined Sard 4th again, after she 

 had been exercised a little, but there was no apparent change for 

 the worse. Indeed after taking her temperature, which was 

 slightly below the normal, and carefully examining both lungs, Dr. 

 Bailey said, ,4 I should not be able to condemn her from what I 

 have seen of her to day." 



Sard 4th was killed and the right lung appeared sound. The 

 anterior lobe of the left lung was slightly adherent, contained a 

 small tuberculous abscess, and adhering to its surface and within 

 its substance were a number of small tubercles. The diseased 

 portion of the lung was so far forward that the difficulty in detect- 

 ing the extent of the disease in the living animal was accounted 

 for. An examination of the rest of the heid failed to reveal any 

 more diseased animals, although one heifer was regarded with
