The manikin’s flaps correspond to lecture topics such as the circulatory system, the brain and nervous system, the skeleton and muscles, venereal disease and the physiology of reproduction (male and female), first aid, and the dangers of corseting (visible in the far right). D r. Franke’s Phantom (1891), a deluxe edition of White’s Physiological Manikin, also contains flaps showing the stages of gestation and possible positions of fetuses and twins—a pregnant hermaphrodite. The German “Dr. Franke” is probably a corruption of “Dr. Frank Hamilton,” whose endorsement was featured in American versions and who wrote an accompanying booklet.
