THE BACTERTCIDAL SUBSTANCES OF THE BLOOD 



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 :

Origin of Bacteriolytic Amboceptors. Regarding the origin of the 

 bacteriolytic amboceptors, our knowledge is as yet very meager. 

 The researches of Pfeiffer and some of his pupils suggest that the 

 spleen is possibly more actively concerned in their production than
