Feulgen staining of cul- tures after six hours indicated that the crescent stage of micronuclear division was prominent in all of the conjugating pairs. Prezygotic, meiotic divisions occurred between six and nine hours. At this relatively low population density, however, Counts per minute per 10,000 animals 60. 10 - FIGURE 2.
