ANAEROBIC BACTERIA 187 



sema of the wound and a thin offensive discharge and fatal 

 outcome. After death the bacillus develops rapidly and 

 through the blood-vessels brings on general emphysema, with 

 large accumulation of hydrogen gas in all the organs and 

 subcutaneous tissue. Various foreign observers have de- 

 scribed organisms having similar properties, and have given 

 them such names as Bacillus perfringens, B. enteritidis sporo- 

 genes, Granulobacillus immobilis, B. saccharobutyricus,

but they were probably dealing with the Bacillus aerogenes 

 capsulatus. 



Bacillus Enteritidis Sporogenes (Klein, 1895). Re- 

 garded as identical with B. aerogenes capsulatus (q. v.). 



Bacillus Chauvei. Synonyms. Bacillus of Symptomatic 

 Anthrax (Bellinger and Feser) ; Rauschbrand (German) ; Char- 

 bon symptomatique (Arloing, Cornevin, and Thomas). 



Origin. This bacillus, described in 1879, has been isolated, 

 and by animal inoculation shown to be the cause of the 

 "black-leg" or "quarter-evil" disease of cattle.
