A small accessory bone, the navicular bone, liescrosswise in the foot behind the coffin joint, enlarging the jointsurface. The short pastern projects about 13^ inches abovethe hoof and extends about an equal distance into it. Tendons and ligaments.—The extensor tendon of the toepasses down the front of the pastern and to the top andfront of the coffin bone. The outer branch of the suspensoryligament attaches to the tendon a short distance above thispoint. The flexor tendon of the foot passes down between the. Fig. 115.

The bones ofthe foot are held together by powerful short ligaments. Lateral cartilages and plantar cushion.—The elastic tis-sues of the foot include the lateral cartilages and the plantarcushion. The lateral cartilages are two plates of gristle, one oneither side of the foot, extending from the wings of the coffinbone backward to the heels and upward to a distance of an inchor more above the edge of the hair, where they may be felt bythe
