Observations on Coprozoic Flagellates: Together with a Suggestion as to the Significance of the Kinetonucleus in the Binucleata . st couple ofhours the movement is extremely rapid, but afterwards slows down somewhat. Tofollow such a pair for some hours is the most difficult experience I have ever hadwith a mechanical stage. As the fusion progresses, the united portion of the zygotebecomes larger and larger (figs. F 2 and 3), the free ends of the original spiralsbecoming smaller and smaller, and resembling two short, curved tails. (The flagellaare not indicated, because I could never see them in active Sjnromonas-mdividirals,except with the dark-ground illumination, and that is not feasible in the case ofobservation-preparations.) At length, after 6 or 8 hours, the zygote appears as infig. F 6, only two small protuberances remaining to show the ends of the is now very sluggish, no longer displacing itself, but only rotating now and have not actually followed it to the next stage, because, as mentioned, I wasobliged to break off the observation at this point. But when I left off, there were 2 3 4.
