=Cutting or Brushing= is caused by a foot striking the opposite fetlock or cannon bone. It may occur before or behind; usually behind. It arises from defective structure of the legs, or from wasting of the legs in horses badly fed, so that they are brought abnormally near to each other. =Speedy-Cut.=—The inside of one or both feet usually strikes the fetlock joint of the opposite foot in passing it; but sometimes the cannon bone is struck just below the knee; the bruise thus caused is called “Speedy-cut.” It occurs during fast action, generally in horses with badly shaped legs. It is more dangerous than common cutting, because the pain is more severe and the shock to the system greater, so much so that sometimes the horse falls as if he were shot. Examination may discover a small bare place, partially concealed by adjacent hair, or a contusion, or an abrasion of the skin, or a scab on the inside of the cannon bone. In bad cases the periosteum may be swollen and the bone itself enlarged. TREATMENT.—This should be the same as for common cutting; but in all probability the only effectual remedy will be the construction of a speedy-cut boot, with a pad on the inside of the leg reaching from the knee to the fetlock, kept in position by buckles, and resting on the fetlock joint. =Treads and Over-Reaches.=—These are names given to a wound between hair and hoof, inflicted either on the fore coronary substance by the shoe of the hind foot, or on the hind leg by another horse treading on it. Cart horses may inflict the injury on themselves with the calk of the shoe. These wounds are sometimes difficult to heal in consequence of the difference in organization of the parts injured, the exterior being highly vascular, but the interior cartilaginous. TREATMENT.—Every portion of detached _horn_, _hair_ or _skin_ must be removed and the wound cleansed and dressed with the VETERINARY OIL placed on soft tow and bound up with broad tape. On the third and every subsequent day the dressing may be removed, but warm applications and poultices must be avoided. In cases of neglect or ill-treatment the suppurative process may have become established, and the warm applications may be necessary. If neglected the disease may end in Quittor. In all cases of INJURIES or BRUISES, give A.A., and B.B. in alternation, two doses of each per day. Broken Knee This is a very vague term and may imply simply to a bruise, an abrasion of the skin, or a division of the tendons or of the capsule of the joints. CAUSES.—Mechanical, such as falling or striking the knee against some hard and sharp substance.
