This monograph is an exhaustive microscopic study of an ovum from a young woman who committed suicide by taking phosphorus. After the organs had been hardened in formalin and alcohol, repeated and careful examinations of the endometrium were made with a magnifying glass. At first nothing was detected, but finally a small spot was found, lighter than the surrounding tissue, situated on the posterior wall of the corpus uteri. This spot was carefully excised, hardened and cut into a continuous series of sections. Examination showed that the middle 160 sections comprised a very small ovum, measuring 1.4 mm. long, 0.9 mm. deep and 0.8 mm. wide. No positive information could be obtained regarding the exact age of the ovum. The results of careful and exhaustive study of the 160 sections are embodied in the monograph, illustrated by 16 lithographed plates, comprising 28 figures beautifully printed in colors.
