LIST OP SPECIFICS AND REMEDIES. 39 



the lungs rarely or never remains so, but event- 

 ually involves the pleura more or less, and so an 

 inflammation of the pleura always involves, more 

 or less extensively, the pulmonary substance. 

 The best name, and more common type of the 

 disease, is Pleuro-Pneumonia. 



CAUSES. Catarrh, influenza, cold or bronchial 

 irritation may either of them terminate in this 

 disease if neglected, or from fresh exposure. A 

 sudden transition from heat to cold ; change from 

 a warm stable to a colder one ; neglect of the 

 usual blanketing, or even of other comforts ; hard 

 and long ridding against a cold wind in snowy 

 weather, loitering in an exposed, bleak place, 

 when the horse is fatigued and warm, without 

 covering. It sometimes occurs when horses are 

 suddenly turned out to grass, or when they have 

 been taken up and turned into a very warm 

 stable. Injuries, contusion, rupture, or great vio- 

 lence done to the chest, is quite sure to be followed 

 by pleurisy or Pleuro-Pneumonia. 



SYMPTOMS. For convenience sake, we will in- 

 dicate the symptoms of these two branches of 

 the disease separately. Pleurisy invariable com- 

 mences with shaking all over, followed by a hot, 

 dry mouth, white-coated tongue, red nose and eyes, 

 low spirits, want of appetite, anxious look, and 

 hard, quick, wiry pulse. The act of drawing the 

 air into the lungs is short, and stops, or is cut off 

 at a certain point, at which time the pain is felt ; 

 the act of forcing the air from the lungs, is full 

 and slow. The pain is increased by coughing and 

 taking a full breath, which the horse will do if 

 suddenly moved or frightened. If the inflamed 

 side is pressed upon, he gives forth a sound like a 

 grunt ; the cough is short ; the horse remains 

 standing ; the skin on the inflamed side is thrown
