Cause.—Generally follows congestion of the lungs. It may be due to parasitic organisms or exposure to cold, drafts when warm after being driven, etc. Drenching perhaps is the most common cause as it is very difficult for a cow to swallow when the head is elevated; inhaling smoke, gases, etc., also tend to produce pneumonia.

Symptoms.—Chilling or shivering, temperature elevated to 105° or 106° F., nose hot and dry, horns and legs cold. Pulse rapid though strong, breathing fast and the appetite very good in some cases. The animal urinates small quantities of urine but often, of a dark amber color. A discharge from the nose follows, also a cough. If the ear is placed back of the fore leg, a dry crackling sound can be heard something on the order of rubbing hair between the fingers.

Treatment.—Place the animal in a dry, well lighted and ventilated stable, but avoid drafts. Give Pulv. Iodide of Ammonia, one ounce; Pulv. Potassium Nitrate, four ounces; Pulv. Nux Vomica, four ounces; Pulv. Capsicum, one ounce; Quinine, one ounce. Mix well and make into thirty-two powders. Place one powder in gelatin capsule and administer every three or four hours with capsule gun. Supply the animal with fresh water at all times. Feed laxative food as hot wheat bran mashes or steamed rolled oats. Also feed vegetables, such as potatoes, apples, carrots and kale. It is also advisable to apply the following over the region of the lungs just back of the fore legs: Aqua Ammonia Fort., four ounces; Oil or Turpentine, four ounces; Raw Linseed Oil, six ounces. Mix and shake well and apply two or three times daily. It is also advisable to hand rub the legs and bandage them with woolen cloths.

If the above treatment is properly carried out, the animal will make a complete recovery in a week or ten days.
