THE HOOF. 239 



PI. 53 with PI. 50), as compared to the width of the hind 

 fetlock ; the easier will the eye of the observer run down the 

 hind leof. 



Cannon and Fetlock. — Concerning these parts, I have 

 nothing to add to what I have already written in this chapter 

 and in the preceding one, beyond saying that if the leg is 

 of good width immediately below the hock, its shape will be 

 all right down to the fetlock. 



Pastern and Hoof. — As the hind limb is concerned more 

 in propulsion than in resisting the evil effects of concussion ; 

 its pastern should be more upright, than what would be 

 required in that of the fore leg. The hoof should more 

 nearly approach the perpendicular, than the fore one ; Its 

 slope, when viewed in profile, being, in unshod horses, about 

 60°. It is, as compared to its length, narrower ; the ground 

 surfaces of its quarters are straighter ; and their respective 

 curvatures differ less from each other, than those of the fore 

 extremity. The horn at the toe is not so thick ; the sole is 

 more concave ; the frog is narrower and less developed ; and 

 the heels are higfher and closer top'ether.
