Text Appearing Before Image:
92 KAYO OKAZAKI AND KATSUMA DAM (3) Half-larvae of the 16-cell stage: Meridional halves: equi- and toti-potcnt with respect to metamorphosis. Of 45 pairs of half-larvae obtained by meridional section of the 16-cell stage, 6 pairs and 13 singles completed metamorphosis. Early half-imagos resulting from this operation are indistinguishable from those derived from the 2-cell stage. Equatorial halves: animal half fails to metamorphose; vegetal half slwivs zvcak capacity for metamorphosis, always followed by immediate death.
Text Appearing After Image:
FIGURE 6. Quartettes derived from single blastomeres of the four-cell stage, 4 days after metamorphosis. A, C, oral view. B, D, aboral view. Their developmental condition is very poor as compared with half-imagos, and further, there is a lack of uniformity in their respective rates of growth. X 160.
