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.
