. Special report on diseases of the horse . Horses. 570 DISEASES OF THE HOESE. At rest, the observer should stand in front and note the slant of the long pasterns. Do they drop perpejidicularly, or slant downward and outward (base-wide foot), or downward and inward (base-nar- row foot) ? Whatever be the direction to the long pastern, an im- aginary line passing through its long axis, when prolonged to the ground, should apparently pass through the middle of the toe. But if such line cuts through the inner toe the foot-axis is not straight, as it should be, but is broken inward at the coronet, an indication that either the outer wall of the hoof is too long (high) or that the inner wall is too short (low). On the contrary, if the center line of the long pastern falls through the outer toe the foot-axis is broken outward at the coronet, an indication that either the inner wall is too long or the outer wall too short. The observer should now place himself at one side, two or three paces distant, in order to view the limb and hoof in profile. Note the size of the hoof in relation to the height and weight of the animal,. Fio. 6.—a. Side view of foot with tlie foot-axis broken backward as a result of too long a toe. The amount of liorn to be removed from the toe in order to straighten the foot- axis is denoted by ii dotted line; 6j side view of a properly balanced foot, with a straight foot-axis of desirable slant; c, side view of stumpy foot with foot-axis broken forward, as a result of overgrowth of the quarters. The amount of horn to be removed in order to straighten the foot-axis is shown by a dotted line. and the obliquity of the hoof. Is the foot-axis straight—that is, does the long pastern have the same slant as the toe, or does the toe of the hoof stand steeper than the long pastern (fig. 6e) ? In which case the foot-axis is broken forward at the coronet, an indication, usually, that the quarters are either too high or that the toe is too short. If the long pa
