PLATE III. 



FIG. 4. Zone of injection 4 days after experiment. A great number of 

 phagocytes have completed the digestion of the ingested edestin ; others con- 

 tain still either small groups or even single particles of edestin. Three 

 granular leucocytes with edestin in their cytoplasm are seen to have been 

 ingested by the lymphoid phagocytes. The phagocytes become much less 

 numerous than in the preceding stage. 



FIG. 5. Zone of injection 7 days after experiment. A thin scar remains 

 after completion of digestion of the injected edestin. It consists of mesen- 

 chymal cells, scarce histiotopic wandering cells (lymphoid phagocytes) and a 

 few vessels traversing the zone.
