940 SWINE AND THEIR DISEASES. 



parts present at first a red or crimson, afterward a reddish lead- 

 gray, and finally a purple color. The fever is fisually very high, the 

 animal breathes with increasing difficulty, and either lies down or 

 sits on its haunches like a dog. The mucous membrane of the 

 v mouth changes from a red-brown to a lead-gray color, the tempera- 

 ture of the body falls below the normal height, and the patient dies 

 within one or two days, either of suffocation or in consequence of 

 the spreading gangrene. Sometimes, when the morbid process has 

 concentrated itself in the larynx, the patient dies from suffocation 

 within an hour after the appearance of the symptoms. Malignant 

 angina, as well as other forms of disease that are apparently allied 

 to anthrax, have, it seems certain,. a parasitic origin, brought about 

 by eating the meat, bipod, or other means of inoculation or infection, 

 furnished by animals that actually have or have died from the mala- 

 dies ; or else these, germs come from the debris or leavings of the 

 same.

This, sometimes called St. Anthony's" Fire or Wild Fire, is in 

 some countries a frequent disease of swine. It seems to be of cryp- 

 tbgamic origin. The. symptoms are more or less pain, though often 

 unobserved. Shortly before the outbreak the animal appears dull 

 and weak, refuses its food, has an unsteady gait, lies down a great 

 deal, and roots in its bedding, or buries its head in the straw. The 

 temperature of the .'body is variable, cold shiverings and feverish 

 heat alternating in quick succession; pulse and respiration are ac- 

 celerated.. The skin of the head, neck, and back becomes colored, 

 and. covered with blisters, allowing a serous fluid to escape. The
