Fig. 126. Degenerated cell from embryo No. 336 (18 cm but near the point of hatching). The cell is glassy in appearance and there is no chromatin in the nucleus. Magnif. as before.

Fig. 127. Degenerating cells from embryo No. 282 (over 10 cm). The nuclei are faint and the cells have sharp outlines.

Magnif. 525. Fig. 128. Much degenerated cells from embryo No. 323 (19 cm). Nucleoli absent. One cell vacuolated and fissured. Haematoxylin and eosin stain. Magnif. as before.

Fig. 129 (a-d). A series of degenerated cells from embryo No. 322 (19 cm). Magnif. a-c 225, d 525.

Fig. 130. Very much degenerated cells from embryo No. 336 (18 cm, see Fig. 126). Magnif. (SEIBERT, 4 mm) 225.

Fig. 131 (a-d). Four similar cells from various sections of a newly hatched skate (No. 375, over 19 mm). Magnif. as before.
