SHOEING.

another. It is this pad which .secretes the wall of the hoof. Be- 

 low the pad the integumental membrane presents itself under the 

 form of rosy leaves pressed one against another, and so disposed 

 as to facilitate the gliding of the horn which i.s continually pass- 

 ing over it. This leafy 

 tissue is called leaves of 

 flesh or podophyllous tis- 

 sue. The podophyllous 

 tissue is continued under 

 the foot by a velvety tis- 

 sue similar to that of the 

 pad, and which secretes 

 the sole and the frog. 



B. The external parts 

 of the foot, to the num- 

 ber of four : the Wall, 

 the Sole, the Frog, and 

 the Periople, forming- 

 together a horny box. 

 The Jtoof, the interior 

 cavity of which is exact-

 face of the sub-mural

 working one within the 

 othei", thus completing 

 the general structure of 

 the foot by furnishing to 

 it': sensitive parts an 

 envelope thick, hard, i-e- 

 sisting, yet elastic, incor- 

 porated with them and 

 protecting them against the violence of bodies with which the 

 foot, by the very nature of its functions, is required to )je inces- 

 santly in contact. See Figs. 376, 377, and others further on. 



The wall is that pai't of the horny case which forms its front 

 and sides, but it does not end, as many may suppose, at the heels ; 

 it is folded back and prolonged to a point toward the extremity 

 of the frog. These prolongations of the wall arc termed the bars,
