Figs. Nos. 7 to 9, inclusive, photographs of amoeba “11524.” A description of 
this ameeba will be found in our first report. It was grown from the stool of a 
dysenteric patient. 
No. 7. Old, eneysted culture, showing distinction between endo- and ecto-plasm 
and absence of nucleus. 
No. 8. Transplant from No. 7, showing two cystic and three vegetative forms. 
No. 9. Transplant from No. 8, showing full grown vegetative form. The 
spinous pseudopodia formation, which was distinct in the specimen 
viewed under the microscope, is barely visible in the photograph. 
The nucleus which was very distinct is slightly out of foes. 
In this connection attention is invited to figs. 7 to 11, inclusive, 
of our first report, which are also reproductions of this same ameeba. 
Fig. No. 10. Twenty-four-hour-old transplant from growing culture of an amoeba 
from a dysenteric stool. Amplification about 1,200. Showing very prominent 
nucleus with heavy nuclear membrane and nucleolus situated eccentrically. 
The distinction between ecto- and endo-plasm is usually very sharp in this 
ameeba, and its motility is as a rule very sluggish.
