348 THE EXTERIOR OF THE HORSE. . 



The width of the head, qr, below the inferior eyelids. 



The lateral width of the forearm, vh (Fig. 125, A), taken from its origin in front to the point 

 of the elbow. 



9th. Two-ninths of the head give : 



The vertical elevation of the point of the elbow above the sternum, hx. 

 The depression of the back, IV , in relation to the summit of the withers. 

 The lateral width of the legs, vw', close to the hocks. 



The opening, g (Fig. 125, B), or rather the distance between the forearms, from one axilla to the 

 other. 



10th. One-sixth of the head equals : 



The thickness of the forearm, h (Fig. 125, B), seen in front, at its origin, from the axilla to its 

 external contour horizontally. 



The width of the coronet of the anterior feet, h (same figure), either from one side to the other 

 or from before to behind. 



The width of the coronet of the posterior feet, h (Fig. 125, C), from one side to the other only. 



The width of the posterior fetlocks, k (Fig. 125, A), from in front to behind. 



The width of the knee, h (Fig. 125, B), seen in front (measure a little large). 



The thickness of the hocks, h (Fig. 125, C) (measure a little small). 



llth. One-twelfth of the head gives: 



The thickness of the anterior canon, n' (Fig. 125, B) ; the posterior, n" (Fig. 125, C), is a little 

 thicker. 



12th. One-ninth of the head equals : 



The thickness of the forearm in its narrowest part, m' (Fig. 125, B). 



The thickness of the posterior pasterns, m', seen laterally (Fig. 125, A). 



13th. The height of the elbow from the fold of the knee (Fig. 

 125, A, below) is the same as: 



The height of this same fold to the ground, o'n' (Fig. 125, .4). 

 The height of the patella above the fold of the hock, qw. 

 The distance from the fold of the hock to the coronet, wd'. 



14th. One-sixth of the preceding measure (13th) gives: 



The width of the canon of the forefoot, a' (Fig. 125, A), viewed laterally in the middle of its 

 length. 



The width of the anterior fetlock viewed in front, a" (Fig. 125, B). 



15th. One-third of the same measure (13th) is almost equal to : 

 The width of the hock from the fold to the point, r (Fig. 125, A). 



16th. One-quarter of the same measure (13th) gives: 



The width of the knee seen laterally, cf (Fig. 125, A). 

 The length of the knee, c" (Fig. 125, A). 



17th. The space between the eyes from one angle to the other, s 



(Fig. 125, B\ equals: 



The width of the leg or tibial region seen laterally at the level of the fold of the buttock, r'r' 

 (Fig. 125. A). 



18th. One-half of this interval between the eyes gives : 



The width of the posterior canon seen laterally, v (Fig. 125, A). 

 The width of the anterior fetlock seen laterally, v' (Fig. 125, A). 



Finally, the difference of the height of the croup in relation to the summit of the withers, py (Fig. 

 125, A).
