The birth of twins counted among high-risks deliveries in Madame Du Coudray’s time, as caesarean sections were not performed in those days.
The twin foetuses are more rudimentary models, so their fingers and toes are not individualised. This accessory was designed to be observed, rather than handled, during the study of twin pregnancies. Each doll measures 25 cm, which corresponds to a five-month pregnancy. Each foetus has its own circulation, but both are linked by their umbilical cord to a single placenta with a diameter of 10 cm, divided in two by a membrane of cotton voile. The maternal side of the placenta consists of two half-sponges.
