The outer, or fibular, side, shown best in figure 4, is short along the line of the foot, being encroached upon by the articular face for the calcaneum on the proximal end, and one for the fifth metatai'sal on the distal end. The plantar aspect of the bone (figure 3) presents a single, or bifid, tubercle, and, on the inuer face (figure 2), is an elongate articular surface for union with the navicular. This surface is confluent with the face for articulation witli the astragalus, and thus serves to distinguish the proximal from the distal end of the bone, which often closely resemble each other. The proximal surface (figure 5) is covered by two articular facets. The inner one, large and sub-triangular, concave in both directions, and nearly perpendicular to the axis of the bone, moved, during life, upon the outer distal face of the astragalus. This face is, in the specimen figured on the Plate, widely confluent with a smaller oval face for the calcaneum. In figure 146, below, the face for the calcaneum (c) is much less widely confluent with that for the astragalus, being nearly separated from it. In both specimens, the calcaneal face is slightly convex transversely, and somewhat inclined to the axis of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marsh, Othniel Charles, 1831-1899.
