William Hunter's casts of the gravid uterus at the University of Glasgow.

The Hunterian Collection at the University of Glasgow possesses 11 plaster casts showing the pregnant uterus. Three correspond to Plates I, IV, and VI of Hunter's The Anatomy of the Gravid Uterus Exhibited in Figures (1774), progressive stages of dissection of the same specimen. A further three casts show consecutive stages of dissection of a uterus containing a fetus presenting by the breech. The other specimens show a normal pregnancy at about 6 months, a normal full-term uterus with the fetal head becoming engaged, a breech presentation with placenta previa and the umbilical cord around the fetal neck, and an obstructed labor with distended bladder and colon. The 10 on display show realistic coloring and are mounted on black wooden stands. An 11th specimen, amateurishly painted, is not on display. The casts differ in their style; some show only the abdomen, pelvis, perineum, and thighs, others show the full torso. They also differ in the amount of detail shown. The first three casts show the cut femur and muscles at the transected ends of the thighs, also shown in some of the plates in the Gravid Uterus. Although these features enhance the artistic impact of both the engravings and the casts, the authors are unconvinced that Hunter deliberately used them to achieve this, as has been claimed.
