Plate 1
FIG. 1. Ovarian egg obtained by puncture of a follicle from the ovary of an unmated rabbit.
FIG. 2. Ovarian egg obtained by puncture of a follicle from the ovary of a doe mated 2 hours previously. The chromatin material condenses to tetrads. The vesicular membrane is still present.
FIG. 5. Ovarian egg from a doe mated 6 hours previously. The first polar spindle begins to form.
FIG. 6. Ovarian egg from a doe mated 8 hours previously. The first polar body has been given off.
FIG. 9. Ovarian egg from a doe which had received 2 cc. thyroxin intravenously. Tetrads have formed in a vesicular nucleus.
FIG. 10. Ovarian egg from unmated doe, inseminated with normal sperm in vitro. Sperm penetration has occurred. Note sperm head at lower right periphery.
