Oi the three species of Amctbce found in these cultures, 

 Amceha protcus was sometimes the pioneer, and was the only one 

 to assume even subdominance. Amoeha Umax occupied the inter- 

 mediate period for development, while Amwha gutivJa was the 

 last to appear. 



The thecamoeba, EuglypJta sp., appeared early. Euglypha 

 alveolata was much less common and appeared late in culture, 

 as did the other representative of the group, Diffiugia globnlosa. 



The composite sample, Liesbeek 13, in addition to contain- 

 ing representatives of practically all the commoner Protozoa 

 observed, appears to have shown development of them relatively 

 early, and in some cases, for example, Cyclidhini glaucoma, 

 Pcrancma trichopJiorum, Holophrya ovum, Actinophrys sol, the 

 Protozoa were observed in the culture of the composite sample 

 l)efore thev were seen in the cultures of the individual soil lavers.
