Two-month-old macrocysts incubated continuously at 20° C. and removed from an agar plate immediately before being photographed; note the single macrocyst at upper right which still contains endocytes.

Macrocysts similar to the preceding, but removed from agar and incubated in distilled water at 20° C. for 10 days prior to photography; note that little evident change has taken place

FIGURE 41. Macrocysts like the preceding, but incubated for 10 days at 10° C. just prior to being photographed; note the empty cyst cases and the mass of free myxamoebae which have escaped from these. X 300. FIGURE 42. Photomicrograph showing a second field from the same preparation shown in Figure 41 ; note the broken walls of the empty cyst cases, also that a few myxamoebae still remain within the germinating cyst at top center.
