THE study of the pathogenic anaerobic micro-organisms has until recently 

 been much neglected, but thanks to the work of Veillon and his pupils, interest 

 in this branch of bacteriology has now been aroused. A rich bacterial flora 

 has been found in gangrene and in gangrenous suppurations and it is desirable 

 that the principal species isolated should be shortly described here. 



I. BACILLUS PERFRINGENS. 



THE Bacillus perfringens is an anaerobic organism discovered in 1898 by 

 Veillon and Zuber in conditions of gangrene. Certain organisms which were 

 previously known and to which various names were given are now believed 

 to be identical with the Bacillus perfringens : the following must be regarded 

 as coming within this category : 



1. The bacillus discovered by Achalme in 1891 in acute articular 

 rheumatism ; 



2. The Bacillus aerogenes capsulatus of Welch, which was found in the 

 tissues of a dead body ; 



3. The Bacillus phlegmonis emphysematosce isolated by Frsenkel from a 

 phlegmonous inflammation. 



The Bacillus perfringens is exceedingly wide- spread. Achalme found it in the 

 blood of persons suffering from rheumatism and in the myocardium of two individuals 

 who had died of acute articular rheumatism ; Veillon and Zuber in gangrenous 

 suppurations (appendicitis, etc.) ; Guyon, Albarran, Jungano, in urinary abscesses ; 

 Frsenkel in an inflammatory swelling ; Guillemot in a case of gaseous gangrene ; 

 Jungano in cases of chronic urethritis ; Chaillous and Benedetti in ocular infections.
