CONTAGIOUS AND EPIZOOTIC DISEASES. 37 



finest of the flock, and the bodies of its victims are found dead 

 in- the field. There is first halting on a limb, then a red or 

 violet swelling beginning inside the leg and rapidly extending 

 over the body. The feeling, appearance, and course of the- 

 swelling agree with those of black-quarter, and death occurs in; 

 a few hours, or in exceptional cases in two days. 



(D) In Swine. — These suffer from Anthrax of the Mouth, 

 comparable to black-tongue, carbimcular erysipelas, like that of 

 the sheep, pharyngeal anthrax and tumours about the throat, 

 Avhich sometimes at least have the anthrax characters. 



(i) The Carbuncular Erysipelas has been constantly con- 

 founded in systematic veterinary works with intestinal fever ; but 

 it is a distinct disease, being derivable from other anthrax 

 patients and communicable to other genera of animals and to 

 man, whereas hog-cholera is absolutely confined to swine. 



(2) Malignant Sore-throat. — Pharyngeal Atithrax, — This is 

 perhaps the most frequent form of the disease in swine, often 

 appearing to arise from eating the carcasses or excretions of 

 other anthrax animals. There is active fever with redness and 

 swelling of the throat, neck, breast, and even the fore limbs. 

 This is at first hard, elastic, warm, and tender, but becomes 

 purple, cool, insensible, and pits on pressure. There is loss of 

 appetite, retching, vomiting, purple patches, and black spots on 

 the eyes, snout, and skin, difficult breathing through the mouth, 

 livid tongue, decreasing temperature, great weakness, and death 

 in one or two days. 



(3) In the guttural tumours the swelling is circumscribed to 

 the size of a kidney-bean or egg, on one or both sides of the 

 throat, extending to the throat generally, causing vomiting, 

 difficult breathing and swallowing, the general symptoms of 

 anthrax, and death from suffocation often under twenty-four 

 hours. It attacks pigs of five or six months. 



(E) Dogs and Cats. — These suffer when they have eaten 

 Uie carcasses of anthrax victims. The disease usually localizes
