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.

“Baldy–Webster operation”. Webster’s method of treating retrodisplacement of the uterus was later modified by J. M. Baldy, Amer. J. Obstet. Dis. Wom., 1902, 45, 650-54, and N.Y. med. J., 1903, 78, 167-69.
