influenced demands all our energies to prove ourselves worthy of it. EXPLANATION OF WOOD-CUTS. THE HUMAN FOOT. Fig. page 1 9 Bones of foot, with the lower ends of the two leg-bones. 2 11 Bones of the hind foot of a seal, with lower ends of leg-bones. 3 11 The same of the hind foot of a lizard. 4 14 Side view of the pelvis and lower limb of man. A, the _haunch-bone_. B, the _ischium_, or part upon which we sit. C, the _thigh-bone_. D, the _knee-pan_. E, the _tibia_, or larger leg-bone, with the _fibula_, or smaller leg-bone, alongside it. F, the _heel-bone_. G, the _metatarsal_ bones. H, I, K, the _phalanges_, or bones of the toes. 5 14 Similar view of the pelvis and hind limb of a horse. The letters refer to the same parts as in the preceding figure. 6 18 Represents a section through the lower end of the tibia and through the _heel-bone_, the _astragalus_, _navicular_ bone, inner _cuneiform_ bone, and the bones of the _great toe_. It shows the arrangement of these bones in the arch of the foot and the disposition of the plates of which these bones are composed. 7 25 The same bones as in preceding, with two connecting ligaments. A, the _plantar ligament_. B, ligament passing from the heel-bone F to the scaphoid bone E. D the _Astragalus_. C, one of two small bones, called _sesamoid_ bones, usually found at the ball of the great toe. 8 29 A foot, in an aggravated condition of “flat-foot.” The sole is convex, and so is the inner margin of the foot. It represents also another common deformity, inasmuch as the great toe runs athwart the second toe, which is pressed almost out of sight. 9 38 Front view of the right _tibia_, or larger leg-bone. 10 38 Right _tibia_ lying on a board. The inner, as well as the outer edge, of the upper end rests upon the board; but the inner edge of the lower end is turned away from the board. In other words, the bone is so twisted that, though the upper end lies flat upon the board, the lower end touches it only by its outer edge. 11 40 Figure sitting upon the heel to draw the bow. It is one of a beautiful series of statues in the Glyptothek at Munich. They adorned the pediments of a temple in Ægina, and are supposed to represent the noble actions of the Æacidæ.
