BACILLI WHICH PRODUCE SEPTICAMIA. 499 
more are known to us from experiments made in pathological labora- 
tories, in testing by inoculations into animals bacteria obtained from 
various sources, with reference to their pathogenic power. We in- 
clude in this group only those bacilli which induce fatal septicemia 
‘in susceptible animals when injected into the circulation or sub- 
cutaneously in a comparatively small quantity—e.g., less than half 
a cubic centimetre of a bouillon culture. 
BACILLUS SEPTICHMIA HAMORRHAGICA, 
Synonyms.—Bacillus of fowl cholera; Microbe du choléra des 
poules (Pasteur); Bacillus cholere gallinarum (Fligge); Bacillus der 
Hiihnercholera ; Bacillus of rabbit septicemia; Bacillus cuniculi- 
cida (Fliigge) ; Bacillus der Kaninchenseptikimie (Koch) ; Bacillus 
der Rinderseuche (Kitt) ; Bacillus der Schweineseuche (Léffler and 
Schiitz) ; Bacillus der Wildseuche (Hueppe) ; Bacillus der Biiffel- 
seuche (Oreste-Armanni) ; (Bacterium of Davaine’s septiczemia ?) 
It is now generally admitted by bacteriologists that Koch’s ba- 
cillus of rabbit septicemia (1881) is identical with the bacillus 
(‘‘micrococcus”) of fowl cholera previously described by Pasteur 
(1880). The similar bacilli found in the blood of animals dead from 
the infectious diseases known in Germany as Wildseuche (Hueppe), 
Rinderseuche (Kitt), Schweineseuche (Schtitz), and Biiffelseuche 
(Oreste-Armanni) appear also to be identical with the bacillus of 
rabbit septicemia and fowl cholera. This view is sustained by 
Hueppe and by Baumgarten, and by the comparative researches of 
Caneva (1891) and of Bunzl-Federn (1891).

With reference to the American swine plague ee ea 
described by Salmon and Smith, we are informed by (aumgarten.) 
Smith, in his most recent publication upon the subject 
(Zeitschrift fiir Hygvene, Band x., page 493), that cultures of the 
German Schweineseuche bacillus, received from the Berlin Hygienic 
Institute, compared with his cultures from infected swine in this 
country, agreed in all particulars, except that the former were de- 
cidedly more pathogenic for swine and for rabbits. 
It appears extremely probable that the form of septicemia studied
