Ingestion of Carbon bacteria (B. anthracis) by phagocytes of 



THE Blood. 



1. Some bacteria have been introduced into the blood (elongated rods in the center of the photograph); a 

 leucocyte arrives (at the top) among the red globules (dark disks); 2, twenty-two minutes later, the 

 leucocyte has ingested the bacteria; another appears at the top; 3, an hour later, other leucocytes are 

 grouped about the first phagocyte.
