T ribes II, III, &c. to XII are then broken up in the same way, and 
then each group — i to 31 — is subdivided according to its microscopic 
characters as follows. I have put it into tabular form. 
I. Aerobian forms. 
Section A, growing at 2 o° Centigrade. 
(a) The organism is a coccus. 
Tribe I. Pathogenous forms. 
* Capable of growth on ordinary nutritive gelatine. 
+ Colonies white or grey. 
§ Liquefying the medium.

And so on with each of the other groups.
