The following engraving illustrates some of the accidents which attend upon injured sight in the horse. The eyes are probably more important to the safety and pleasure of the master than any other portion of the quadruped's frame. Let the smallest impediment exist, and there is no telling in what way it may operate. Certain horses are most affected by near objects; others exhibit alarm only when bodies are approaching them; another class of creatures will look upon most forward sights with indifference, but will invariably be horror-struck whenever the view is extensive; while a fourth group will shy violently without mortal vision being able to recognize any cause for terror. In every case, the dread excited overmasters all other feelings. The presence of extreme fear releases the horse from the dominion of its proprietor; its movements are sudden, jerking, and eccentric; the animal has lost all self-control, and there is no saying in what direction it may move or what it may attempt to do. It is regardless of its own life, therefore it is careless about the welfare of others, and he is very fortunate who possesses such a servant and escapes without accident. There is no cure for a disposition depending upon a change of structure; but there may be a preventive. Would all horse-owners preserve their tempers and forbear from slashing a horse over the head, they would be vast gainers in a pecuniary sense, and would certainly escape very many of those ills now commonly attendant upon equestrian exercises. Whoever has a shying horse had better discard the creature from all private uses. Send the animal to some work in which the habit will be accompanied with less danger, or never allow the quadruped to quit the stable without having the sight securely blinded. Such things are necessary; but the feeling man, when he considers how much the exercise of the senses sweeten mere animal existence, will sigh over the order which compels him to deprive a horse of that which the common sense of the English has denominated "precious sight." =Simple ophthalmia= is inflammation of the fine membrane which covers the horse's eye; it reaches no deeper, it does not affect the internal structures of the organ, and it is not so much to be dreaded in its immediate as in its after consequences. It is caused by accident and by the violence of man.
