If both the horn and core have been broken off, bleeding is usually severe and should be checked by astringents, such as alum, or by pressure. After the hemorrhage has ceased the exposed portion of the fracture should be covered with pine tar, with or without a bandage. An imperfect growth of horn will in due time cover the exposed bone. FRACTURES OF THE BONES OF THE FACE.--These occasionally occur, and when over the cavities of the nose produce depression, disfigurement, and impeded respiration, owing to the lessening of the caliber of the nasal passages. When such accident occurs, the depressed bone should be gently forced back to place by introducing the finger in the nostril, or if the fracture is too far up for this, a probe may be passed and the parts retained by placing immediately over it a plaster of thin leather or strong canvas smeared with tar, extending out to the sound surroundings, taking care to embed the hair over the fractured portion in the tar of the plaster, so that it will be firmly held and prevented from again becoming depressed. If only one nostril is involved, the depressed portion may be held in position by packing that nostril with absorbent cotton. This practice, however, has the objection of giving the animal great discomfort and in some cases a disposition to aggravate the injury. FRACTURE OF THE SKULL (CRANIUM).--Fractures of the bones forming the cavity in which the brain is situated are, owing to their strength, comparatively rare among cattle. Such an accident can only be the result of external violence, and it is hardly possible that it could occur without some fragment of the broken bone pressing upon the brain so as to cause coma or other severe nervous derangement, or even death. If the animal survives the first shock, the efforts should be directed toward relieving the pressure, which may be done by making an opening in the bone (trephining), and with a hook drawing the depressed part outward. Interference is not so liable to be attended with good results as to be warranted in all cases. The effects of a very severe shock which may not have produced a fracture, although the symptoms were alarming, will in many cases pass off, leaving the animal in a better condition than if an operation had been performed. FRACTURE OF THE LOWER JAW.--This occasionally occurs, and is more liable to result from the kick of a horse than from any other cause. The front part of the jaw may be split or shattered in any direction in which the force may have been applied. Bloody discharges from the mouth and failure to eat or ruminate are symptoms most likely to attract attention.
