Contagious and lipizootic Diseases. 49 



Avunt of pliancy in tlie skin, slightly increased tempera- 

 ture (102°), weak, accelerated pulse, mawkish breath, stiff- 

 ness of the limbs, wandering perhaps from one to another, 

 shght, infrequent, dry cough, and blue, watery milk, often 

 abundant but with cheesy matter, fat and sugar decreased 

 and soda and potassa in excess. The lymphatic glanda 

 about the throat are often manifestly enlarged. SweUiugs 

 of the joints may appear, or a murmur harsher than natu- 

 ral 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 fbuUers) though conception and the completion 

 of gestation are usually impossible. Working oxen are 

 easily overdone and become visibly emaciated fi'om 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 pink vessels, 

 a whitish discharge often takes place from the nose, 

 and with it an increased repulsiveness and often distinct 

 foetor of the breath ; if the bowels are involved scouring is 

 common, and if the bones, swelling and lameness inci-ease. 

 Exhaustion with profuse perspiration and labored breath - 

 ing occur on the slightest exertion, the appetite fails, tym- 

 pany follows each meal, and the milk is at once poorer 

 and lessened in quantity. The cough increases, becomes 

 ratthng, the discharge profuse, foetid, mixed with cheesy- 

 like or chalky particles, crepitating, wheezing, gui-gling 

 and other abnormal noises are heard in the chest, and 

 percussion shows dullness in particular parts with winc- 

 ing. All of the symptoms become steadily aggravated 

 and the animal usually perishes from the difficulty of re- 

 spiration or the profuse foetid diarrhoea. In cases affect- 

 ing the bones, the patient may be unable to stand and 

 the bony prominences may make their way through the 

 skin or even crumble under the pressure thrown upon
