Fig. 9. — The daughter-plates separating. 
Fig. 10. — The daughter-plates widely separated ; reconstitution of 
the daughter-nuclei beginning. 
Fig. 11. — End of nuclear division ; one daughter-nucleus is completely 
reconstituted, the other shows remains of the spindle. Division of the 
cell-body beginning. 
Fig. 12. — Encysted amoeba, about to escape from the cyst. 
Fig. 13. — Empty cyst with rough wall. 
PLATE 17. 
Large type of amoeba from liver-abscess. Figs. 11—16 are counter- 
stained with Lichtgriin-picric after iron-hsematoxylin; figs. 17-20 are 
stained with Twort’s combination of neutral red and Lichtgriin. 
Figs. 14 and 15. — Amoebae with ingested bacteria; in fig. 14 the 
karyosome appears to be breaking up. 
Figs. 16-21. — Amoebae showing endogenous bud-formation. 
Fig. 16. — Amoeba with two buds, one very small, in the earliest stage 
of formation, the other full-sized, with the chromidia beginning to form 
the nucleus. 
Fig. 17. — Amoeba with full-sized bud, which contains only scattered 
chromidia. 
V 
Fig. 18. — Similar stage, the nucleus of the bud beginning to be 
differentiated. 
Fig. 19.— Amoeba with three buds, two in a very early stage of forma- 
tion, the third full-grown, with nucleus completely differentiated. 
Fig. 20. — Amoeba containing fully-formed bud. 
Fig. 21. — Young amoeba, not full-grown, containing a bud which is 
full-sized and has the nucleus in an advanced stage of differentiation. 
PLATE 18. 
Figs. 22-24. — Small type of amoebae from the liver-abscess, showing 
stages of the division of the nucleus. Stained with Delafield’s 
hsematoxylin. 
Figs. 25-29. — Amoeba from dysenteric stools. Figs. 28 and 29 show 
early stages of nuclear division. Iron-hsematoxylin. 
Fig. 30. — Amoeba isolated from Bombay tapwater. Iron-hsema- 
toxylin. 
Figs. 31 and 32. — Amoebae from the rectum of a monkey. In fig. 27 
the nucleus has recently divided. Iron-hsematoxylin.
