76 THE MODERN HORSE DOCTOR. 



PLEURISY. — (Plmritis.) 



The internal cavity of the chest and the outer surface of the 

 lung are lined and covered with a highly-organized membrane 

 termed the pleura : here the disease locates itself. In the early 

 stage, the disease is termed acute, and in the latter, chronic. The 

 disease sometimes terminates in suppuration ; so that, on examin- 

 ing a case after death, shreds and flakes of matter will be found 

 adhering to the pleural membranes. Now and then, the disease 

 terminates in mortification. 



" In 1830, a four-year-old horse was discovered at 7 o'clock 

 in the morning, in his stall, sweating profusely ; heaving hard and 

 quick at the flanks, and puffing at an equal rate at the nostrils ; 

 pulse but very indistinctly to be felt; mouth hot and clammy; 

 legs intensely cold ; head hung down, and countenance betraying 

 serious malady ; eyes and nose reddened, and the latter moist 

 with yellowish-bloody matter; breath fetid as well as mouth. 

 When pressed upon the side, he flinched and turned his head, and 

 evinced much soreness. As soon as he was got dry and warm 

 from the cold sweat he was in, he was bled ; scarcely, however, 

 had two quarts of dark thick blood flowed before he began to reel. 

 The treatment afterwards was such as is ordinarily pursued; 

 but to no purpose. The pain he manifested was extreme. He 

 would rub his nose against the rail across the doorway of the box, 

 thrusting his lips violently against it ; his eyes sinking with suf- 

 fering. He -was twice seen to lie down, but immediately rose 

 again. Towards the conclusion, a bloody issue appeared at the 

 nose. Before death, he became delirious, and expired in dreadful 

 agony. Water within both sides of the chest — from six to eight 

 quarts ; pleura intensely inflamed ; costal portion every where 

 most minutely and thickly injected ; pulmonary portion, covering 

 the lungs, likewise injected, but it had also become gangrenous — 

 it exhibited a green hue; lungs partly tuberculated ; otherwise, 

 and particularly in the interim, they were sound." — Hippo- 

 pathology. 



From the tuberculated state of the lungs, there was, probably 

 some previous indisposition, which accounts for the rapid course
