Anomalies of the Feet.--Hatte has seen a woman who bore a child that had three feet. Bull gives a description of a female infant with the left foot double or cloven. There was only one heel, but the anterior portion consisted of an anterior and a posterior part. The anterior foot presented a great toe and four smaller ones, but deformed like an example of talipes equinovarus. Continuous with the outer edge of the anterior part and curving beneath it was a posterior part, looking not unlike a second foot, containing six well-formed toes situated directly beneath the other five. The eleven toes were all perfect and none of them were webbed. There is a class of monsters called "Sirens" on account of their resemblance to the fabulous creatures of mythology of that name. Under the influence of compression exercised in the uterus during the early period of gestation fusion of the inferior extremities is effected. The accompanying illustration shows the appearance of these monsters, which are thought to resemble the enchantresses celebrated by Homer. Anomalies of the Hand.--Blumenbach speaks of an officer who, having lost his right hand, was subsequently presented by his wife with infants of both sexes showing the same deformity. Murray cites the instance of a woman of thirty-eight, well developed, healthy, and the mother of normal children, who had a double hand. The left arm was abnormal, the flexion of the elbow imperfect, and the forearm terminated in a double hand with only rudimentary thumbs. In working as a charwoman she leaned on the back of the flexed carpus. The double hand could grasp firmly, though the maximum power was not so great as that of the right hand. Sensation was equally acute in all three of the hands. The middle and ring fingers of the supernumerary hand were webbed as far as the proximal joints, and the movements of this hand were stiff and imperfect. No single finger of the two hands could be extended while the other seven were flexed. Giraldes saw an infant in 1864 with somewhat the same deformity, but in which the disposition of the muscles and tendons permitted the ordinary movements. Absence of Digits.--Maygrier describes a woman of twenty-four who instead of having a hand on each arm had only one finger, and each foot had but two toes. She was delivered of two female children in 1827 and one in 1829, each having exactly the same deformities. Her mother was perfectly formed, but the father had but one toe on his foot and one finger on his left hand. Kohler gives photographs of quite a remarkable case of suppression and deformity of the digits of both the fingers and toes. Figure 123 shows a man who was recently exhibited in Philadelphia. He had but two fingers on each hand and two toes on each foot, and resembles Kohler's case in the anomalous digital conformation. Figure 124 represents an exhibitionist with congenital suppression of four digits on each hand.
