and the angles which they 

 form at the heels, the deft. 

 The external surface of the 

 wall is glossy, as though var- 

 nished ; its internal surfac/ 

 is striated throughout, except 

 at the hollowed bevel at its 

 upper edge; the striae of the 

 external face of the wall 

 (horny laminae, keraphyllous 

 tissue) are designed to work 

 into the fleshy laminae or po- 

 dophyllous tissue. The bevel 

 at the upper edge of the in- 

 ternal face of the wall, hol- 

 lowed like a groove, is de- 

 signed to receive the pad, and 

 is pierced with a number of 

 small openings, into which 

 penetrate the filaments of the 

 pad, which are true hair-cells.

A. The outside nerve, or that part of it 

 where the branch H communicates; E. 

 The suspensorj' ligament ; C. The great lig- 

 ament of the back sinew ; D. The two 

 back sinews, or flexor tendons ; E. E. The 

 extensor tendon ; F. The cannon or shank 

 bone ; G. The splintbone, which is placed 

 on each side, rather posteriorly, ofthe shank 

 bone, beginning immediately under the 

 knee,and extending tapering downward, 

 and terminating at fig. 1 in a sort of bulb ; 

 H. The back sinews and their great sus- 

 pensory ligament, apparently joined to- 

 gether. This, however, is not the case ; it 

 incorporates only with the perforans ten- 

 don, marked fig. 2, and so intimately, that 

 they form one and the same substance, at 

 the part marked by the small letter '. 

 The perforatus, marked fig. 3, forms a 

 sheath for the perforans, as already de- 

 scribed in the article Strains. 4. The knee 

 joint. 5. The fetlock -joint.
