Tubercles may be developed in any part of the body, as 

 the lungs, their serous covering, the membrane supporting 

 the bowels, the coats of the intestines, the throat, the spleen, 

 the liver, the pancreas, the ovaries, the kidneys, the bones, 

 especially the ends of long bones, and in I'are cases, the 

 muscles and connective tissue. 



Synvptoms vary according to the seat of the deposit, yet 

 there is a constitutional condition common to all, and the 

 lungs are almost always involved in the later stages, giving 

 rise to a great similarity of symptoms. The disease may be 

 acute but is usually chronic. The onset is insidious and 

 easily overlooked, tubercles being often found in animals 

 killed in prime condition, and I have seen thera in parturi- 

 tion fever, which is always attributed to plethora. There is 

 some dulness, loss of vivacity, tenderness of the withers, 

 back, and loins, and of the walls of the chest, occasional dry- 

 ness of the nose, heat of the horns and ears, want of pliancy 

 in the skin, slightly increased temperature (102°), weak, 

 accelerated pulse, mawkish breath, stiffness of the limbs, 

 wandering perhaps from one to another, slight, infrequent, 

 dry cough, and blue, watery milk, often abimdant but with 

 cheesy matter, fat, and sugar decreased and soda and potassa 

 in excess. The lymphatic glands about the throat are often 

 manifestly enlarged. Swellings of the joints may appear, 

 or a murmur harsher than natural may be heard over the 

 lower end of the windpipe or in the chest. With deposits 

 in the abdomen and especially in or near the ovaries of 

 cows the desire for the male is often constant (bullers), though 

 conception and the completion of gestation are usually im- 

 possible. Working oxen are easily overdone and become 

 visibly emaciated from day to day. As the disease advances 

 the eyes sink in their sockets and lose all animation, the 

 skin is hidebound, harsh, dry, and scurfy, the hair dull, dry- 

 and erect, the membranes of the eyes, nose, and mouth of a 

 pale, yellow, bloodless aspect, though often streaked with
