twelve, many presented more or less extensive old adhesions 

 of the lungs to the ribs and diaphragm. None had serum in 

 the chest. In the lungs were yellow, friable, caseous nodules 

 of various sizes, the smallest being perhaps a line, the largest 

 four or five inches in diameter. The central portions of some 

 of these being soft, were apparently surrounded by thick, whitish 

 membrane ; but this, from the irregularity of its inner surface, 

 was prol)ably only a portion of the original mass, which had not 

 been broken down. In some, marked calcareous degeneration 

 had taken place. The bronchial glands in a number of cases 

 were much enlarged and similarly diseased. In one instance 

 like formations existed in the liver ; and in another, two cysts 

 were found external to the lung, one about six inches in diame- 

 ter, the other not more than three. Tlieso botli contained a 

 yellow fibrinous material and calcareous matter. 



On microscopic examination nothing was seen but pulmo- 

 nary tissue, small irregular granular cupuscles, with granular 

 and fatty matter. None of these were characteristic of any 

 particular disease, and appeared to be the result of some degen- 

 erative process. 



We have not thought it necessary to give in detail the differ- 

 ent examinations, as tlie appearances were in all the same. No 

 disease was supposed to exist in a majority of the animals 

 slaughtered. 



Quite a number of animals were found in this herd with 

 diseased lungs, and a healthy pleura, but not one with disease 

 of the pleura without disease of the lungs. Several of the 

 diseased animals that were killed, it was said, had never 

 appeared ill. 



There have been tliree animals killed at East Lexington 

 showing no disease save a slight adhesion of the ])ericardiuni to 

 the heart, no larger than the finger nail, which is of no conse- 

 quence. 



One animal was killed at Princeton belonging to Justin Eames, 

 of Milford. The neighborhood being alarmed, the animal was 

 sacrificed to appease their fright, and found sound. 



One cow was killed belonging to John T. Abbott, of ITolden, 

 for a like cause, with a like result. More of this Abbott cow 

 hereafter.
