is distinguished from B. coli by being smaller and more delicate. Its 

 motility is very marked. Coagulation of milk is delayed, and the litmus 

 present is completely reduced. It forms no gas in lactose-litmus, and 

 grows freely therein. Indol reaction is negative. Thus culturally and 

 morphologically B. "S" resembled in some ways B. dysenterm, in others 

 B. coli and B. typhosus. 



The specific agglutinins developed in animals from this bacillus did 

 not react with B. dysenterm, B. coli, and B. typhosus. Serum from one 

 patient agglutinated the bacillus isolated from this patient, but did not 

 react with other organisms from the same source. The author claims 

 that this bacillus, B. "#," has not hitherto been described, and was the 

 cause of the epidemic alluded to.
