| RECORD NUMBER | HOURS AFTER BEGINNING OF INSEMINATION | NUMBER OF OVA | STAGE OF DEVELOPMENT |
| 60 | 1 day, 18 hours | 7 | 2-cell stage |
| 59 | 2 days | 8 | 2-cell stage |
| 58 | 2 days, 17 hours | 8 | 7, 2-cell stages; |
| 61 | 2 days, 18 hours | 8 | |
| 62 | 2 days, 22 hours | 11 |
| 1, 3-cell stage | 2-cell stage | 10, 2-cell stages; | 1, 3-cell stage
Thus in all 40 ova after the completion of the first segmentation division and 2 ova in the 3-cell stage, in each of which the
undivided blastomere presents a nucleus in mitosis.
