The inner surface presents a. finely pitted appearance,which is most marked at the toe and round its part immediately related to the frog shows feAV pits,and we shall find that the whole surface corresponds tothe sensitive parts to which it is attached. The structure of the sole is, like the wall, fibrous;but the fibres are smaller. They run downwards andforwards in the same direction as those of the v/all. Theouter layers are the hardest and protect the deeper Fig, 6.—The Frog, detached from the Sole. The Frog is the smallest division of the hoof, andis a triangular shaped body filling up the space left be-tween the bars. (Fig. G.) Its broad base is rounded andprominent, and is continued laterally by a thin layerwhich binds tocrether the heels and envelopes the back of FORM AND ACTION OF THE FOOT. 11 tke foot. This thin layer is contimious, with a hornyLand extending round the iipper part of the wall at with the hair, and sometimes prolonged down-wards on the surface of the wall. (Fig. 7.) It appears to
