THE EXTERIOR OF THE HORSE. 



ulars, and observing if the point b (centre of the foot) is midway be- 

 tween / and h or s and u, it suffices to fix the point k, middle of the 

 humerus, or the point v, middle of the distance comprised between the 

 points of the shoulder and of the elbow, and then draw a vertical line 

 which should fall upon the same foot. 



Now that we have established the rational principles which indicate 

 the location of the axes of the anterior members, we can formulate 

 from them practical rules in the following manner. Our lines differ 

 somewhat from those of other authors, but in principle they are 

 equally as simple, and have, besides, the advantage of being based 

 upon positive facts. 



1st. A vertical line, ab (Fig. 149 [1]), lowered from the middle, k, 

 of the arm, should pass, above, through the centre of anterior suspension, 



a, intersect, below, the middle of the hoof, b, and be located equidistant 

 from the verticals ef, gh, coming from the point of the shoulder and the 

 summit of the elbow. 



If this line falls in front of the hoof, the horse is said to be under 

 himself in front (Fig. 149 [2]).
