Obstetric tables was published as a training aid at a time when it was becoming difficult for medical students to gain clinical experience. It contains a large number of layered illustrations that can be lifted to provide ‘dissected’ views of the female body in pregnancy. Some of the plates contain as many as four or five layers, showing for example the different stages of pregnancy, the position of a baby during birth, and use of forceps in an assisted delivery.
