 differences in the behavior of such sera exist, and that the sera from 

 certain animals only will serve to activate others. 



These interrelations (worked out for hemolytic amboceptors on 

 the one hand and bacteriolytic amboceptors on the other, both 

 normal and immune) are shown in the following table:
