INJURIES TO THE JAW.
Causes.—Pulling the snaffle; abuse of the bit; too tight a curb-chain.
Symptoms.—Discoloration before or behind the tush; bruise under the tongue or upon the roof of the mouth; tumor and bony growth upon the margin of the lower jaw.
Treatment.—Cut upon the discoloration till the knife reaches the bone; if fetor is present, inject the chloride of zinc lotion; keep the wounds open, that the injured bone may come away.
LACERATED EYELID.
Causes.—Nails in the gangway, or the horses playfully snapping at each other.
Treatment.—Bathe with cold water till the bleeding ceases; allow the separated parts to remain until the divided edges are sticky; bring together with sutures; place the horse in the pillar-reins till the healing is perfected.
LACERATED TONGUE.
Causes.—Sticking to a horse when giving physic; making a "chaw" of the halter-rope.
Treatment.—Insert no sutures; if the arteries are excised, cut off the hanging portion of the tongue; should the vessels have escaped, allow all to remain; feed on gruel and soft food; after every meal wash out the mouth with the solution ordered for aphtha, or with the chloride of zinc lotion.
