liquor acetate of ammonia in 2 ounce doses three or four times a

The best veterinary surgeons now all agree that bleeding is 

 not only unnecessary but injurious in treating pneumonia and 

 pleurisy. 



PLEURISY. 



As before stated, pleurisy is inflammation of the pleura. 



Symptoms. It may be sudden or gradual in its attack, the 



horse showing indispo- 

 sition, sometimes for 

 days previous. He will 

 be dull and heavy in ac- 

 tion for a day or two, 

 unwilling to lie down,

in ; breathing at flanks a little accelerated, countenance is anxious, 

 the head is sometimes turned toward the side, does not lie down. 

 As the disease advances, the symptoms become more marked. 

 The ears and legs become cold ; the pulse, from being a little 

 accelerated, grows quicker, hard, and full ; the head is hung for- 

 ward ; stands up persistently ; breathing hurried ; the membrane 

 of the nose and eyes red. 



Turning the horse round, or hitting against the chest, back of 

 the shoulder, will cause a kind of grunt. 



The ear applied to the chest will detect a rough, rasping noise, 

 and there is generally present a short, painful, suppressed cough, 

 easily excited by pressure on the larynx. 



Causes. Are similar to those of pneumonia, such as variations 

 in temperature, exposure to cold while warm, standing in draught 

 of cold air, impure air, etc. Pleurisy occurs as an independent 

 disease, or, as before stated, may be accompanied by inflammation 

 of the lungs. If neglected or not treated properly, is a very dan- 

 gerous disease.
