TABLE VIII. — Miquel, 189 r. 
Miquel first separates the aerobian from the anaerobian forms, sub- 
dividing according to the temperatures, as follows : — 
I. 
Aerobian , growing 
at 20 0 C. . . = Section A 
only above 20° C. = „ B 
only above 40° C. = „ C 
II. 
Anaerobian , growing 
at 20 0 C. . . = Section D 
only above 20 0 C. = ,, E 
only above 40° C. = „ F 
He then proposes to break up the ‘ Sections ’ into ‘ T ribes,' as 
follows : — 
Section A — i. e. Aerobian species which grow at 
20° C.

The following tabular statement shows how Miquel then proceeds 
to further subdivide each ‘Tribe' of each ‘Section' into ‘Groups,’ 
according as the forms will or will not grow on nutrient gelatine, the 
colour and other peculiarities of the colonies, and so on.
