THE BACTERICIDAL SUBSTANCES OF THE BLOOD 



to use as complement the blood of a certain animal rather than that 

 of another; but it is essential to remember that considerable differ- 

 ences 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:
