CAUSE.—Is due to deep seated inflammation of the eye produced by an injury or weakened condition of the optic nerve. SYMPTOMS.—If the pupil of one of the eyes appears larger than the other it is well to make a careful examination, as this is the first sign of Cataract. If such a condition is neglected, partial or complete blindness will follow and a white, pearly deposit can be seen on the lens of the eye. TREATMENT.—Very unsatisfactory unless treated carefully when the first signs are noticed. Place the animal in a darkened stable. Feed clean, sloppy food and it may be necessary to give a physic consisting of two drams of Aloin, two drams of Pulv. Ginger, placed in a capsule and given with capsule gun. The following ointment: Yellow Oxide of Mercury, four grains; Lanolin, one ounce, should be mixed well and applied to the eye two or three times a day. CATARRH. CAUSE.—Ill ventilated stables, inhalations of irritating gases or sudden exposure to cold, wet weather, after being accustomed to warm stables. Most commonly seen in the Spring or Fall. SYMPTOMS.—Chilling and temperature elevated one or two degrees, pulse not much affected, breathing hurried to some extent, sneezing, coughing, dullness and the appetite is slightly impaired. In the first stages the nostrils are very dry and considerably inflamed, but in the course of a few days the fever subsides and a profuse discharge from the nose is observed. TREATMENT.—Place the animal in dry, well ventilated stall, blanket well and supply a good quality and quantity of bedding. Give inhalations from steam and hot water and Pine Tar. If the animal is constipated, give rectal injections of Soap and Warm Water two or three times a day. Also administer Potassium Nitrate, Pulv. Nux Vomica, each four ounces; Capsicum, two ounces, and Pulv. Ginger two ounces. Make into twenty-four capsules and give one capsule three or four times a day. This should not be neglected, as neglected Catarrh is liable to be followed by Laryngitis, Bronchitis, Pneumonia, Pleurisy or other diseases of the organs of breathing, which are very serious and sometimes cause the death of the animal. CHAPPED TEATS. CAUSE.—Anything that tends to irritate them. A sudden chilling of the teat in cold weather after the calf has just let it go, or after the operation of milking with wet hands or from an animal wading through deep water or tall wet grass. Also filth or irritants coming in contact with teats when lying down. TREATMENT.—Remove the cause if possible and dry the teats well after each milking and apply Zinc Oxide ointment. Feed laxative food that is easily digested, as it has a very good effect on the blood, consequently it promotes the healing of wounds. CHOKING. (_Obstruction of the Esophagus_)
