Fig. 1000.— Acute Pleurisy. - sharp, cutting pain causes 



the animal to turn his 

 head toward the side. (See Fig. 1000.) Percussion on the ribs elicits 

 clear and resonant sounds, but auscultation detects the friction 

 sound, like two pieces of leather rubbed together, in addition to 

 the usual respiratory murmur. Resolution frequently follows proper 

 treatment, and the deposits are re-absorbed. A sudden subsid- 

 ence of the acute symptoms denotes effusion into the pleural sac, 

 or hydrothorax. In this stage, the pulse becomes soft, the breathing 

 is labored, with prolonged expiration, less pain is manifested on 

 pressure of the sides, and the animal feeds freely. The extent of the 

 effusion may be observed by auscultation and percussion. The lat- 

 ter test gives a dull sound as high as the fluid has risen in the 

 chest ; the former an absence of all sound below the same line. 



Treatment. — Bleeding is not called for. Laxatives may be 

 freely administered, for there, is no such tendency to diarrhea as is 

 sometimes seen in pneumonia. If the pain seems to be very acute, 

 the following may be administered, and repeated in a few hours if 

 relief is not obtained : — 



Tincture of opium (laudanum) } to 1 oz. 



Linseed oil 1 pt. 



External stimulation must be resorted to, in the form of mus- 

 tard applications to the sides, or prolonged fomentations with hot 

 water. . It is essential to keep the animal quiet, and warmly clothed. 

 Give good food, and plenty of water to drink, adding an ounce of 

 saltpeter to a bucketful of water. After the acute symptoms have 

 subsided, a half ounce of tincture of muriate of iron, in a bucket of 

 water, will be found useful. To hasten the absorption of the effused 

 fluid, give the following as a ball or drench twice a day : — 



Iodide of potassium. 1 dr. 



Carbonate of ammonia , 1 " 



.Gentian (powdered) 1 oz
