THE BEGINNINGS OF LIFE. 



with him in this view, my own observations do 

 pretty closely accord with his, as to the future fate 

 of these so-called 'micrococci/ When introduced into 

 a fluid capable of undergoing alcoholic fermenta- 

 tion, they develop, according to Hallier, into bodies 

 resembling ordinary yeast cells or ToruU (named by 

 him <^ cryptococci'), whereas in an acid fluid, or one 

 which becomes acid by the establishment of a new 

 kind of fermentation, they assume an elongated form, 

 and constitute one variety of what are ordinarily termed

Bacteria (or ^ arthrococci ^ in the nomenclature of 

 Hallier). Micrococci and arthrococci are said to mul- 

 tiply by fission^ whilst cryptococci increase by a process 

 of gemmation. By an elongating growth^ accompanied 

 by the formation of septa at intervals^ arthrococci are 

 said to be capable of developing into distinct fungi 

 of the O'ldtum type. Thus^ according to the nature 

 of the fluids^ ^ micrococci ' develop either at once into
