PLEURI& 
65 
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 copious bleeding is the first 
thing to be resorted to ; and afterwards sedative medicines, 
administered in the form of gentle purgatives, which may be 
given with 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 water 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 • • • i 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 drachms; 
made into a ball with palm-oil.
