genesis and at most only cell division can occur in their absence;
lithium salts have specific effects on morphogenesis; and combinations
between alien cytoplasm and nuclei, often somewhat effective at first,
are eventually overwhelmed by cumulative disharmony.
Because many of these morphogenetic processes in Stentor have been
correlated with the cortical cell pattern, it seems possible that the principles governing them will turn out to be functions of a cytoplasmic
pattern. For morphogenesis this would have the advantage that form
need not be derived from the self-organization of free molecules, but
would arise by elaboration of pre-existing form. It remains to be seen
whether such morphogenetic actions as induction and specific inhibition
can, in ciliates, be explained satisfactorily in terms of patterns, and
thereupon, what bearing this could have on our approach to these problems in multicellular forms.
