Most of the microbes of which we have now to speak 

 may be assigned to one or other of the genera given in 

 this scientific enumeration, and sometimes, on account 

 of their polymorphism, to several of these genera. 



Before making a more detailed study of some of 

 them, it may be interesting to glance at them as a 

 whole, following the order of classification given above. 

 The genus Aficrococcus (Hallier) includes the 

 spherical microbes, which are the most common and 

 the most widely diffused, probably because the spores 

 ^ and early stages of all the other forms 



. V*!P>"*. have this spherical shape before be- 

 coming elongated and assuming their 

 adult form (Fig. 50). 



This genus is divided into two 

 (,S, sections: the first includes Micro- 

 coccus ckromogenis, i.e. fabricators of 

 colouring matter an extremely interesting group, on
