BACTERIAL ANTIGENS AND SPECIFICITY 367 



specific antigenic structure in the different types. Ivanovies and 

 Bruckner (1937) (1938) and Tomcsik and Ivanovies (1938) have 

 described a new type of hapten which they have isolated from the 

 capsular substance of two aerobic spore producers, B. anihracis 

 and B. mesentcrkus. It is a polypeptide of liigli molecular weight 

 containing only one amino acid.
