12. The leg consists of two bones, of which the one is much more slender than the other at one part, but not much more slender at another. These are connected together at the foot, and form a common epiphysis, but they are not united together along the line of the leg;and at the thigh they are united together and form an epiphysis, and this epiphysis has a diaphysis; but the other bone in a line with the little toe is a little longer. Such is the nature of the bones of the leg.
