N2  - Records were kept of 7284 rat eggs, 1120 mouse eggs, and 221 rabbit eggs. Amongst these were 22 rat eggs, 21 mouse eggs, and 1 rabbit egg that were unusual: "giant" eggs of about twice the normal volume, primary oocytes recovered from the fallopian tubes, probable instances of gynogenesis and parthenogenesis, eggs showing abnormalities of fertilization such as the presence of a single pronucleus or of a male and two female pronuclei, and 2-cell eggs with a binucleate blastomere. These anomalies are discussed and attempts are made to explain their occurrence.
