 previous neglect. Let the foot always 

 be pared level, and the shoe properly 

 adjusted to the wall, and corns will 

 find no abiding place in feet possessed 

 of these conditions. 



To determine where the seat of 

 lameness is, take my foot testers (Fig. 

 195), and clasp around the union of sole 

 and wall. If the horse does not flinch 

 or yield, grasp the foot at point of 

 frog. If he yields to the pressure, thin 

 the sole at that point. On close ex-

Hard corns are protuberances growing upon the inner sole, 

 at its junction with the horny laminae, and lie beneath, as well 

 as at the side and rear of the foot bone. They consist of a 

 hardened excrescence of the skin, which crowds in upon the 

 sensitive surfaces, and thus become the source of much trouble 

 and pain. The corn may be generated by severe contusions upon 

 the inner sole, but it generally arises from a lateral compression 

 of the horny hoof inward upon the sensitive parts. 



The vertical pressure of the horse's weight upon the foot 

 bone is oftentimes so severe, and its winged extremities are 

 pressed down upon the underlying tissues of the sensitive sole
