and is called the har portion of the coronary hand. It is also 

 covered with villi, which are directly continuous with those of 

 the fleshy frog. The coronary band secretes the principal part 

 (middle layer) of the horny w^all of the hoof, including the 

 bar portion (bars) of the wall. 



3. The fleshy wall, or podophyllous tissue (Figs. 27, 28, d, 

 and 29, a), is all that portion of the pododerm on which there 

 are fleshy leaves. This leafy tissue covers the anterior surface 

 of the OS pedis and the lower por- 

 tion of the external surface of the 

 lateral cartilages. At the bulbs of 

 the heels it turns inward at a sharp 

 angle and extends forward and in- 

 ward, between the bar portion of 

 the coronary band and the poste- 

 rior part of the velvety tissue of 

 the sole, nearly to the middle of 

 the solar surface of the foot, to 

 form the lamince of the bars (Fig. 

 29, a). The fleshy wall and fleshy 

 bars are not covered with villi, but

the lower border of the os pedis. 

 Between the fleshy leaves are deep furrows in which, in a 

 foot which has not been deprived of its homy capsule, lie the 

 homy or insensitive leaves of the wall. The fleshy leaves (podo- 

 phyllous laminee) are related to one another somewhat as the 

 leaves of a book ; their posterior borders are attached to the body 

 or basement membrane of the fleshy wall, while their anterior 

 borders and sides are free. At their upper ends immediately 

 below the coronary band the leaves are quite narrow, but they
