Figure 112 represents a boy with congenital deficiency of the lower extremities who was exhibited a few years ago in Philadelphia.

In Figure 113, which represents a similar case in a girl whose photograph is deposited in the Mutter Museum of the College of Physicians, Philadelphia, we see how cleverly the congenital defect may be remedied by mechanical contrivance.
