The first cross-sectional anatomy of the pelvic anatomy during the puerperium, the period of about six weeks after childbirth during which the mother's reproductive organs return to their original non-pregnant condition. Webster reproduces in color cross-sectional anatomies of women who died of diseases on the 1st, 2nd, 3rd, 4th, 6th, and 15th days of the puerperium. The final chapter describes and illustrates with cross-sectional images "the femal pelvis in the beginning of the fifth month of pregnancy." Digital facsimile from the Internet Archive at this link.
