CLASSIFICATION OF THE BACTERIA. 75 
SECTION (B): Micrococcus ZyYMOGENES. 
Globular bacteria producing fermentations of 
diverse nature. 
M. crepusculum, Cohn (Monas crepusculum, Ehrb.). 
Globular cells, colorless, developing in all in- 
fusions of animal and vegetable matter under- 
going decomposition. 
M. urez, Cohn. 
Oval cells, isolated, diameter 1.5 p (Pasteur), 
1.2 to 2 w (Cohn) or united by 2, 4, to 8 (to- 
rula), in a line, straight, curved, zigzag, or even 
in cross form. In urine of which it transforms 
the urea into carbonate of ammonia (Pasteur). 
A Torula which appears identical with the 
preceding Jficrococcus, produces the decomposi- 
tion of hippuric acid into benzoic acid and gly- 
collamine (Van Tieghem). 
M. of stringy wine, etc. 
Globular cells of 2 mw diameter, in chaplets, 
found in stringy wine, perhaps identical with 
the preceding (Pasteur). 
A Torulacez quite similar is found in certain 
fermentations of tartrate of ammonia and of 
beer yeast, with or without the addition of car- 
bonate of potash (Pasteur). 
SecTIOoN (c): Mrcrococcus PaTHOGENES. 
Spherical bacteria found in affections of a con- 
tagious nature.
