The frog should be carefully pared down and all loose, ragged portions removed in order to prevent the accumulation of matter and dirt. The discharge wiped off by means of a tow pressed down into the cleft with a thin piece of wood. Then smear the frog and cleft with a mixture composed of half an ounce of _sulphate of copper_ (blue vitriol) and six ounces of tar made into a paste or the VETERINARY OIL. A small piece of tow dipped in this mixture should also be placed in the cleft, or in whatever part of the frog a sinus, hole or cleft exists. In bad cases, repeat the dressing daily; in others, once in two or three days is sufficient. If the dressing is properly applied it will not fall out or admit the entrance of dirt. Should the frog be extensively diseased, a bar-shoe may be necessary, and the dressing will then be kept in place by the cross bar of iron, or a leather sole may be used under the shoe. Throughout the treatment give fifteen drops of I.I., each morning and fifteen drops of J.K., every night, for the growth of healthy hoof. CHAPTER IV.—PART I. DISEASES OF THE EYES Albugo, or Spot in the Eye, Opacity of the Cornea In consequence of a blow, stroke of a whip, or similar injury, an inflammatory action is set up in the eye, the result of which is an effusion of serum between the lamina of the outer coating of the eye, which renders the cornea or clear part of the eye, whitish or opaque in spots, interfering materially with the sight and usefulness of the organ. But little can be done to remove those of long standing, but recent cases, or those where inflammation is just subsiding and the opacity only forming, will be dispelled by frequently bathing the eye with HUMPHREYS’ MARVEL WITCH HAZEL, and giving fifteen drops of A.A., three times per day. In many cases of opacity a portion of soft honey, the size of a small pea, put in the eye daily, has been known to have a wonderful effect in removing such opacities. Amaurosis, Gutta Serena This disease consists in entire or partial loss of vision in consequence of paralysis of the optic nerve, or interruption of its communication with the brain. Injuries of the head, or ball of the eye, or some disease of the brain, are the usual causes. The horse walks cautiously, head elevated, and ears move quickly backward and forward, the eye has a peculiar glassy appearance, and the pupil does not dilate and contract when light is brought near or removed from the eye. But little can be done for these cases. In the earlier stages a dose of A.A., may possibly arrest its progress, but generally it is incurable in man or beast. Cataract
