But as the wound begins to heal it is apt to itch, and the horse will often rub the eye violently to ease the irritation. To prevent this, fasten the animal to the pillar-reins of its stall, and let it remain there till the wound has healed; the injury will in a short time close, but the sutures should be watched. When the holes begin to enlarge, the thread can be snipped. If the punctures be dry, let the divided sutures remain till nature shall remove them. If they are moist, and the wound appears united, you may try each thread with a pair of forceps; should any appear loose, then withdraw it, for after division it can be of no use, and may provoke irritation; however, should it be retained, employ no force; have patience, and it will come forth without man's interference. [Illustration: THE LID, WHEN DIVIDED BY THE TEETH, BROUGHT TOGETHER BY MEANS OF SUTURES. ] Feed liberally, regulate the bowels by mashes and green meat; smear the wound with oil of tar to dispel the flies; for should the accident happen during the warmer months, these pests biting and blowing upon so delicate a part as the eye may occasion more harm than our best efforts can rectify. When the lid is bitten through, the operation is precisely similar; the divided edges are to be brought together by sutures. To prevent needless repetition, an engraving of the bitten lid, after the operation has been performed, is here presented. IMPEDIMENT IN THE LACHRYMAL DUCT. The =lachrymal duct= in the horse is a small canal leading from the eye to the nostril; it commences by two very minute openings near the terminations of the upper and lower lids, at the inner corner of the eye; it emerges upon the dark skin which lines the commencement of the horse's nostril, being on the inner side of the internal membrane. Its use is to carry off the superflux of tears; hence, with human beings, who have a like structure, "much weeping at the theaters provokes loud blowing of noses." The channel being so minute, any substance getting into it soon becomes swollen with the moisture and closes the passage. The tears cannot escape, and being secreted, flow upon the cheek. The perpetual stream pouring over a part not designed for such uses, causes the hair to fall off, and thus forms gutters, along which the fluid continues to run. The flesh at length excoriates, and numerous sores are established; the lids swell and become raw at the margins; the conjunctiva reddens, and the transparency of the cornea is greatly lessened by the spread of inflammation. [Illustration: A HORSE'S HEAD, DISPLAYING OBSTRUCTION OF THE LACHRYMAL GLAND.] The wretched animal in this condition presents a very sentimental appearance to a person ignorant of the facts of the case. The swollen lid, because of its weight, is permitted to close over the eye, while the tears, flowing fast upon the cheek, with the general dejection, gives the creature an aspect of weeping over some heavy affliction.
