I'LEUEISY. ei!" 



Cause. — This disease has its origin from the same causes 

 as inflammation of the lungs, viz., sudden transitions from 

 heat to cold, &c. 



Remedies. — Immediate and cojdIuus bleeding is the first 

 thiug to be resorted to ; and afterwards sedative medicines, 

 administered in the form of gentle purgatives, which may be 

 given Avith more safety than in inflammation of the lungs 

 and ordinary inflammatory cases. 



If pleurisy is violent, it frequently induces dropsy in the 

 chest, as in this complaint a fluid is thrown out from the 

 vessels of the pleura, which, having no means of escaping, 

 lodges in the cavity of the chest. When this is the case 

 little good is to be expected from the animal, and it seldom 

 happens that a complete cure is effected. Sometimes the 

 chest is punctured for it, which may carry off the fluid ; 

 but it too frequently proves an ineffectual remedy. "When- 

 ever it is suspected that w^ater is formed, puncturing should 

 be had recourse to, the opening to be made by the instru- 

 ment called the trochar. The locality where it is inserted 

 is the intercostal membrane, between the seventh and eighth 

 ribs, and as close to the cartilages as possible. Diuretic 

 medicines, in combination with tonics, should be given. The 

 following will be found the best : — 



Turpentine . . . -^ ounce, 



Ginger . . . . -^ drachm, 



Lintseed meal . . • -2 ounce ; 

 made into a ball with common syrup or treacle. 

 Some persons consider the following better : — 



Powdered resin . ^ ounce, 



Ginger . . . \ drachm, 



Lintseed meal . 2 drachma ; 



made into a ball with palm-oil.
