 A plumb-line dropped from the point of the shoulder (middle of 

 the scapulo-hnmeral articulation) should pass down the middle 

 line of the limb, dividing it into inner and outer halves of 

 equal width, and meeting the ground at the middle of the toe. 

 In the base-wide standing position (Fig. 45) the plumb-line 

 falls to the inner side of the limb; the limb extends obliquely 

 downward and outward. To this class belong also the hiee-

narrow (knock-kneed) position, in which the knees are too close 

 together, while the feet stand wide apart, and the toe-wide 

 position (splay-footed, Fig. 46) in which the toes point ob- 

 liquely forward and outward. In base-wide positions either 

 the entire limb extends downward and outward or the foot alone 

 is turned outward. 



The base narrow position is frequently obsei'\''ed in horses 

 with veiy wide breasts. The limbs run do\vnward and inward,

 the outer side of the leg and foot. A special form of the base-
