310 ANTHRAX IN THE PIG. 



attack. It may live on to the seventh, eighth, or ninth day. 

 The cadaveric lesions are similar to those of other forms of 

 anthrax. 



4. Apoplexy in Pigs. This disease often occurs under 

 circumstances when it is quite easy to determine that the 

 malady is not of the nature of anthrax ; but there are differ- 

 ences of opinion as to other forms. 



Thus, I was called the year before last to look at a number 

 of pigs kept by a miller in the suburbs of Edinburgh. Three 

 had died very suddenly and in rapid succession ; others 

 were ill, and some still healthy. 



The pigs had been fed for a day or two on much richer 

 food than they had had previously. They were accustomed 

 to get the mill sweepings, with some bran and kitchen refuse ;

 beautiful condition, died. They suddenly left off eating, 

 appeared restless, had peculiarly prominent bloodshot eyes, 

 foamed at the mouth, and fell over dead. We stopped the 

 food, administered emetics, and the disease disappeared.

 lished in the Medical Times and Gazette for the 29th of 

 November, 1862. 



5. The Hog Cholera. Many names have been applied to 

 this disease. It is known in Ireland as the " blue disease," 

 " blue sickness," " distemper in pigs," " red soldier," and the 

 " hog cholera." The latter names have been also employed 

 for it in America. Continental authors have theorized on 

 the nature of the disease, and named it, in accordance with 

 their respective opinions, typhus, erysipelas carbunculosum, 

 g astro-enteritis, anthrax, &c. 



It is a malady which first affects the digestive organs, and 

 then the blood undergoes changes favourable to transuda-
