 position of the fetlock, though the leg above is too far back of the 

 perpendicular line. 



(6) A hind leg viewed from behind is said to be regular or 

 straight (Fig. 48) when a perpendicular line dropped from the 

 tuberosity of the ischium (see Fig. 1, 9") divides the entire limb 

 into inner and outer halves of equal width and touches the 



ground opposite the 

 median lacuna of the 

 frog. Seen from the 

 side, this line just 

 touches the point of 

 the hock and, passing 

 down at some dis- 

 tance from the flexor 

 tendons, meets the 

 ground considerably 

 back of the heels. A 

 perpendicular line 

 dropped from the 

 hip-joint should pass 

 through the foot, 

 meeting the ground 

 half-way between the 

 point of the toe and 

 the heel (Fig. 42). There are base-wide, base-narrow, toe- 

 wide, and toe-narrow deviations in the hind limbs as in the 

 fore-limbs. 



The hind limbs are base-wide when they, either as a whole or 

 in part, deviate outward from the normal. The " cow-hocJced" 

 position (Fig. 49) is an example of the base-wide ; in this case 

 the points of the hocks are too close and turn towards each other, 

 while the feet are widely separated and the toes turned outward. 

 Base-narrow (Fig. 50) is that position of the hind legs in which 

 the hocks are too far apart (bandy-legged).
