CLASSIFICATION OF THE BACTERIA. 75 



SECTION (B): MICROCOCCUS ZYMOGENES. 



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. ureae, Cohn. 



Oval cells, isolated, diameter 1.5 \L (Pasteur), 

 1.2 to 2 p, (Cohn) or united by 2, 4, to 8 (to- 

 ruld), 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 Micrococcus, produces the decomposi- 

 tion of hippuric acid into benzoic acid and gly- 

 collamine (Van Tieghem). 



M. of -stringy wine, etc. 



Globular cells of 2 ^ diameter, in chaplets, 

 found in stringy wine, perhaps identical with 

 the preceding (Pasteur). 



A Torulacese 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). 



SECTION (c): MICROCOCCUS PATHOGENES. 



Spherical bacteria found in affections of a con- 

 tagious nature.
