THE FOOT IN ITS RELATION TO THE ENTIIIE LIMB. 



In the fore foot the height of the toe usually equals |- the 

 length of the sole, and in the hind -j^. The length of the sole 

 varies little in the fore and hind feet of the same animal, the 

 apparent difference depending on the narrower shape of the 

 hind- foot. 



Compared with that of the plantar margin, the length of the 

 coronary margin in fore-feet is as 9:10; in hind-feet a little 

 more. 



Viewed from below, the foot is almost as broad as long. In

contour it resembles the segment of an oval. The sole is thick 

 and arched. The degree of concavity depends on the size of 

 the foot. The frog is strong, firm, and resistant to the pressure 

 of the thumb. AVhen the foot is lifted, it should stand higher

than the level of the wall, and therefore, during movement, 

 should meet the ground before the quarters and heels. 



The bars, which participate in bearing weight, should be 

 strong and prominent, and should be on the same level as the 

 plantar margin of the wall, at least up to a point opposite the 

 middle of the frog. In some feet the weight-bearing surface 

 includes the lower surface of the frog, all of the sole, and the 

 lower margin of the wall ; in others only those portions of the 

 sole bordering; on the wall are included in it.
