For broken wind, prevention is far more easy than cure; in fact, the utmost which science can at present accomplish is to relieve the distress. To effect this, water should be given only at stated times, and never immediately before work. Four half pails may be allowed each four and twenty hours; one the first thing in the morning, another the last thing at night, and the other two at convenient times during the day. Into every drink of water it is likewise well to mingle half an ounce of dilute phosphoric acid, or half a drachm of dilute sulphuric acid. Besides this allow oats and beans, five feeds each day, with only five pounds of hay; two pounds in the morning, when being dressed, and the remainder in the rack at night. Crush the oats and beans; thoroughly damp all the food before it is presented to the horse, and also scald the corn. Remove all bed by day, and muzzle when littered down for the night. Place a lump of rock-salt at one end of the manger, and at the other put a block of chalk. Such is the little science can propose for the alleviation of an incapacitating disorder. All other recommendations rather concern the owner than the stable. A horse thus afflicted should never be pushed hard or called upon for any extraordinary exertion. Fatigue, when severe, is apt to provoke alarming spasm; a spectacle which the author once witnessed, of an animal which had journeyed far, pulling a heavy load, is represented at the head of this article. The horse had only paused while the carter took his beer, and had received nothing but hay upon the road. It had traveled all night, and it was still in the chains when the writer beheld it on the afternoon of the succeeding day. After death, the body which has suffered from the disease declares the ravage of the malady. The lungs are larger than usual, and always pallid; small bladders containing gas are upon their surface, and when taken from their cavity the organs do not collapse as do the healthy lungs, nor can the air by compression be entirely driven forth. The hand being forced upon the surface elicits crepitation, or provokes a crackling sound, induced by the vapor passing out of one cell into another; for broken wind causes the terminations of the bronchial tubes to give way or to freely communicate one with another. Now, it is within these air-cells that the blood absorbs the oxygen from the inhaled atmosphere, and purifies itself by yielding up carbonic acid. How much must the destruction of their integrity, therefore, affect the entire body! Impure blood cannot nourish a healthy life; and the reader, after the above explanation, will easily account for the ragged and dejected aspect of the horse with broken wind.
