The results showed no correspondence among the separate strains and hence 

 prove them to be nonidentical, a fact which confirms the cultural differences 

 observed in the same organisms. Fox failed to obtain fixation with the serum 

 of a patient and a strain isolated from the glands.

AGGLUTININ ABSORPTION TO DIFFERENTIATE TYPE DIPHTHEROIDS 



The literature on diphtheroids, to my knowledge, does not contain 

 any reference to agglutinin absorption as a method for showing rela- 

 tionships which might exist among overlapping, dosely-related types. 

 In view of the fact that the differences which characterize the accepted
