AiVTHBAX AND CHOLERA. 



945 



We give the classification of these diseases adopted by the latest 

 authorities, a detailed description of the symptoms of each type or 

 variety, as observed in different localities, together with such meth- 

 ods of treatment as have been thoroughly tested. 



The term " Cholera" is made, to include three well-defined forms 

 of disease : anthrax, contagious pleuro-enteritis, and epizootic ca- 

 tarrh. Anthrax has already been described at length. (P. 294.) ',

CONTAGIOUS PEEURO-EMTERITIS. } 



, This is a specific inflammation of the lungs and bowels, accom- 

 panied w^ith red or purple blotches on the skin. These ^blotches 

 have given it the local name of " The Purples," or " The Blue Dis- 

 ease." This is. the most common and dangerous of the epidemic 

 diseases known under the designation of cholera. When it once 

 enters a herd, it attacks every age, sex, and condition, and there is 

 little hope of cure. The investigations of Dr. Klein have proved 

 that pneumo-enteritis, like anthrax, is caused by a bacillus, found in 

 the serous fluids and tissues, but not, as in anthrax, in the blood. 



The symptoms vary with the malignancy of the attack and the 

 part of the animal affected. This fact should be carefully noted, 

 otherwise the varying features of the complaint will be apt to con- 

 fuse the observer. It appears in two form>s— the erysipelatous form, 



and that of malignant sore throat.
