Upon examining the results of the agglutination tests tabulated above, 
we see that in all cases we apparently find a distinction between the 
strains which ferment mannite and those which do not. This is the 
reason why most authors have agreed to Lentz’s and Martini’s proposal 
to distinguish between the acid and non-acid types according to their 
powers of fermenting mannite. While in some instances my results are in 
accord with those of Lentz—i. e., in those sera which were gained by 
the immunization of rabbits, goats, and even horses, against strains “ D,” 
“q,” “H,” “I,” “L,” and “0,” some of which are described in the 
above tables (Tables IV, V, and VI), in most instances my results are 
opposed to his views; particularly is this true with the sera which I 
have obtained by the immunization of animals against the other types 
of the bacilli, as the following table shows:
