Group II 



Culture 2, as of the type B. acidi-lactici (Hueppe). 

 Cultures 9 and 15, as of the type B. aerogenes (Escherich). 

 Culture i 7, as of the type B. coli (Escherich). 

 Culture 18, as of the type B. communior. 



Group III 



Cultures 8 and 24, as of the Para-Gaertner group (Savage). 



4. Experimental swelled cans of sardines have been produced 

 by inoculation with cultures 5, 17 and 18 respectively, and the "Postu- 

 lates of Koch" have been satisfied.
