Fig. 12. — Three small parasites in a small blood corpuscle from the spleen. 



Fig. 13. — Six iutra-corpuscular parasites iuside a corpuscle from the 

 spleen. 



Fig. 14. — Six "amoeboid " parasites from the spleen. 



Fig. 15. — Pear-shaped trophozoite, with somewhat pointed apex at the 

 broader end, and two chromatin bodies, from tail blood. 



Fig. 16. — Gregariniform trophozoite with rod-like, drawn out chromatin 

 body, perhaps preparing for division. 



Fig. 17. — Rather large, somewhat spherical trophozoite, with chromatin 

 body lying in clear zone of protoplasm. From spleen blood. 



Fig. is. — "Amoeboid" trophozoite, with a single pseudopodium iu which 

 lies a chromatin dot. From spleen blood. 



Fig. 19. — Pyriform parasite with chromatic appendage still protruding 

 from the erythrocyte. Probably a "flagellate" form, but no bulb or bead 

 seen on the appendage. Tiiis may be a somewhat abnormal form of parasite, 

 as no other similar one was observed, though it was quite distinct. 



Fig. 20. — Bigeminate pair of free parasites from tail blood. 



Fig. 21. — Group of free parasites in the blood plasma. 



Fig. 22. — Leucocyte probably containing the remains of degenerate, in- 

 fected blood-corpuscles, or remains of free parasites. Only the red chromatin 

 masses of the parasites are left. 



Fig. 23. — Portion of section of liver of infected white rat, showing dilated 

 capillary containing many infected red blood-corpuscles and several (three) 

 leucocytes, with large nuclei. X 1000 approx., somewhat diagrammatic.
