410 BOAKD OF AGRICULTURE. [Jan. 



old heifer that stood beside the cow that died, had a bad 

 cough, disease of the lungs, and enlargement of the external 

 lymphatics, and death was recommended. Another cow, 

 where the sjrmptoms of the disease were very marked, was 

 killed, and the post-mortem showed a similar condition of 

 the internal organs as the one that died. Among the lot 

 was a fine-looking cow, in good flesh, that was heavy with 

 calf, and soon after calving she died from milk fever, and an 

 examination of the lungs found them diseased and broken 

 down in places. The rest of the herd, with one exception, 

 were coughing with more or less lung disease, and the 

 owner was advised to fatten them, and if inspection, after 

 slaughter, showed them free from disease, to be sold. 



Soon after this he was called to another farm to see a cow 

 that had been ailing for some time, and she presented well- 

 marked symptoms of tuberculosis, which an examination 

 after death sustained, having general tuberculosis and phthisis. 

 In about six weeks from this time another cow which had 

 been gradually failing died, and the post-mortem showed 

 similar lesions of tuberculosis as the first cow which was 

 killed, only to a greater extent. A third one was soon killed 

 for the same trouble, and in the barn where these three had 

 been kept nearly all were coughing, although they had the 

 general appearance of health. 



Another case of interest is of a gentleman in Worcester 

 who kept a cow or two to supply his own family with milk, 

 and also some of his neighbors. He had been supplying 

 himself and neighbors for a year or so when he called the 

 veterinarian to one of these cows. The doctor found a 

 mature animal, thin in flesh, temperature 104 degrees F., 

 unmistakable lung lesions, coughing, hurried respiration, 

 but with a good appetite, and giving a good quantity of milk. 

 Death was recommended, and autopsy showed tubercles in all 

 stages of development in the lungs. In about one year was 

 again called to the same barn to see a cow which was showing 

 similar symptoms, and she was a daughter to the one alluded 

 to above. She was killed, and autopsy showed similar con- 

 ditions as the dam. A year or two more passed away and 

 the doctor was sent for again, and another was found with 

 the same symptoms as the two preceding ones ; this one a
