Achlya, the latter behaving much like a true parasite when 

 inoculated under these conditions.

 portion, Achlya shows little power of protecting itself against 

 an infection introduced within the filament. 



VI. An infection with cholera may be delayed, or, when not 

 too far advanced, entirely arrested by the application of weakly 

 acid media outside the filaments. 



VII. Agglutinins of both cholera and Bacillus pyocyaneus in 

 specific serums apparently fail to penetrate in the slightest degree 

 the cellulose wall of the fungus.
