SWINE AND THEIR DISEASES. 



The Erysipelatous Form. — This is probably the most com- 

 mon form of the disease. The animal seems dull, loses appetite, 

 hangs his head, is unwilling to move, and sometimes tries to vomit. 

 The bowels are usually constipated, the excrement hard and dark 

 colored, while the urine is of a dark color and passed with difficulty.

 the form of dark-red or purple blotches, which pass into a bluish 

 black color. These appear usually on the ears, throat, neck, and 

 breast, and inside the fore legs. The discoloration is very apparent, 

 and the blotches whenlonce seen will not be mistaken,. A dark- 

 purple fluid sometimes discharges from the nose, the breathing soon 

 becomes difficult, the hind quarters are paralyzed, and the animal 

 reels along with head and hind legs drooping to the ground. A 

 watery arid fetid diarrhea sets in, and the animal dies in from one to 

 three days.

 on the throat, gradually changing to a dark-purple hue. The local- 

 ization of the morbid process in the throat obstructs the operations 

 of breathing and swallowing. This produces a train of characteris- 

 tic symptoms peculiar to this form. The animal tries to vomit ; 

 there is from the outset difficulty in swallowing ; the breathing is
