 microbe of swite plague, chicken cholera, and rabbit septicaemia Patho- 

 genic to deer, buSalo, cattle, horses, swine, rabbits, rats, mice, goats, and 

 sheep. Variability. Vitality : great in soil, dies in 6 to 20 days when dried 

 and quickly in antiseptics, resistant to heat. Accessory causes : rise of soil 

 water in winter or in spring, drying of marshes in summer, wet, rich, 

 swampy, mucky soils ; youth, gregariousness, carnivorous habit, insects, 

 vermin, wild animals and birds, epizoa, entozoa, wire f^ces, wounds of all 

 kinds, hard, woody provender; inoculations in wounds the most fatal. 

 Symptoms : superficial with hyperthermia, functional disorder ; muscular 

 tremors ; violet mucosse ; segregation ; swelling in intermaxillary space, 

 tongue, throat, neck, dewlap, or elsewhere, not pitting on pressure. Pe- 

 techiae. Death in six hours to four days ; thoracic form kills in four to 

 eight days ; abdominal form with colics, and bloody often frothy foetid 

 faeces. Chronic forms usually pulmonary. Lesions : straw colored exuda-

 isolate and kill affected ; destroy or disinfect carcasses and infected things 

 and places, feeding and drinking troughs and manure. Close and drain in- 

 fected fields. Immunization, by three inoculations with cultures made at a 

 high temperature (86° to 90°) in free air ; or with virus that has been grown 

 in pigeon. In case of deer, drive a few days into a non-infecting enclosure, 

 and then on to a sound range. Treatment.

Definition. An acute bacteridian disease of domestic and wild 

 herbivora and swine, characterized by sudden onset, rapid and 

 fatal course, marked hyperthermia, accelerated breathing and 

 pulse, and extensive gelatinoid or sanguineous extravasation in 

 the intermaxillary space, tongue, skin, subcutaneous or intermus- 

 cular connective tissue, lungs, pleura, pericardium or intestine. 



Historic Notes. It is almost certain that in earlier times this 

 affection was often mistaken for gloss-anthrax, blackquarter, or
