Rot. 



The rot generally appears in the autumn of wet 

 summers, and then continues during winter and 

 spring. The progress of the disease is slow and 

 symptoms as follows : 



The animal often remains behind the rest of 

 the flock, and allows itself to be seized with- 

 out resistance ; it walks with a slow gait, with 

 shaking head and depressed ears ; the loins yie'd 

 to pressure; the eye is dull and watery; the eye- 

 lids are swollen ; the lips, gums, and palate have 

 a pale tint ; the skin is yellowish, white, and ap- 

 pears puffed, and pits on pressure; the wool changes 

 color, loses its brightness, and easily comes off in 

 large flocks, often taking the skin with it ; the dung 

 is soft, urine scanty, of deep red color. Gradually 

 there forms on the upper region of the neck, and on 

 the lower jaw, a soft, indolent tumor, which often 

 appears larger on returning from grazing ; some- 

 times disappears at night, but always returns again 

 by day, antl gradually increases in size. By degrees 

 the animal loses appetite, but there is increased 

 thirst; rumination ceases; lachrymation becomes 

 more and more abundant, and the nose is full of 

 viscid mucus. Then the abdomen swells, with 

 dropsy ; the animal becomes extremely weak, and 

 wastes daily ; remains lying down ; pulse is quick 

 and soft ; and death takes place with convulsions in 

 the midst of diarrhea and progressive coldness of 

 the extremities. Jn opening the body fluke-worms
