m 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.

Tubby has seen a boy of three in whom the first, second, and third toes
of each foot were suppressed, the great toe and the little toe being so
overgrown that they could be opposed. In this family for four
generations 15 individuals out of 22 presented this defect of the lower
extremity. The patient's brothers and a sister had exactly the same
deformity, which has been called "lobster-claw foot."

Falla of Jedburgh speaks of an infant who was born without forearms or
hands; at the elbow there was a single finger attached by a thin string
of tissue. This was the sixth child, and it presented no other
deformity. Falla also says that instances of intrauterine digital
amputation are occasionally seen.

According to Annandale, supernumerary digits may be classified as
follows:--

(1) A deficient organ, loosely attached by a narrow pedicle to the hand
or foot (or to another digit).

(2) A more o
