59 An intact abnormal 5-cell morula showing variation in the size and shape of the blastomeres each of which contains a number of small rounded nuclear fragments. Note intact zona closely applied to the blastomeres, an artifact of fixation. Carnegie 8630, Sequence 7. X 500.
60 A section of the ovum shown in figure 59 to show the variation of nuclear form. The blastomere at the left contains numerous small rounded nuclei or nuclear fragments. The middle blastomere contains a large indistinct nucleolus and the one on the right contains three pairs of chromatin masses that strongly suggest, a disintegrating mitotic figure of triaster type. Note two polar bodies below and artifactitiously ruptured zona. Carnegie 8630, Section 9. X 500.
