_A front hoof of the regular standing position_ (Fig. 79). The inner and outer walls differ but little in direction and thickness. The outer wall is a little thicker and somewhat more slanting than the inner (see Figs. 61 and 62), and its outer circumference describes a larger arc of a circle,—that is, is more curved, as can be seen both at its plantar border and at the coronet. The length of the quarter in relation to the length or height of the side wall and toe is about as 1: 2: 3. The toe forms an angle with the ground of forty-five to fifty degrees (see Fig. 68). The direction of the wall at the toe, viewed from the side, should be parallel with the direction of the long pastern. [Illustration: FIG. 79. Right fore-hoof of the regular position: _a_, side wall; _b_, quarter; _c_, beginning of the bar; _d_, buttress; _e_, middle of the bar; _f_, body of the sole; _f′_, branches of sole; _g_, white line; _g′_, apparent end of the bar; _h_, body of the frog; _i_, branch of the frog; _k_, bulbs (glomes) of the heel; _l_, middle cleft of frog; _m_, lateral cleft of frog.] _A hoof of the base-wide position_ (Fig. 80) _is always awry_, because the outer wall is naturally somewhat longer and decidedly more slanting then the inner (see Figs. 63 and 64). The plantar border of the outer wall describes a large arc, whose sharpest curvature is where the side wall passes into the quarter. The plantar border of the inner wall is straighter (less curved); the outer half of the ground-surface (sole) of the hoof is, therefore, wider than the inner. So long as the hoof is healthy, both branches of the frog are equally developed. The wryness of the hoof depends upon the direction of the limb; therefore, a base-wide hoof should be regarded as a _normally wry hoof_, to distinguish it from hoofs which are wry from disease. _A hoof of the toe-wide position_ (Fig. 81) is distinguished from the preceding by the bending or curvature of the plantar border of the outer toe and inner quarter being often decidedly less pronounced than on the inner toe and outer quarter; therefore, two short curves and two long curves lie opposite each other; in other words, the inner toe and outer quarter, lying opposite each other, are sharply curved, while the outer toe and inner quarter, lying opposite each other, are much less sharply bent or curved. The toes are turned out. The feet are not set down flat upon the ground, but meet it with the outer toe. [Illustration: FIG. 80. Right fore-hoof of the base-wide position.] [Illustration: FIG. 81.
