362 THE STOCK owner's ADVISER. 



Sick. Anything the animal will take should be given in small 

 quantities. If given in large quantities and allowed to remain in 

 the trough it will only disgust the patient. The mustard applica- 

 tions may be repeated three or four times, and should be used 

 alternately with poultices. If the fever be high, tincture of aco- 

 nite, twenty drops; nitrate of potash, three drachms, should be 

 given at interyals of four hours. AVhen the circulation is weak, 

 stimulants should be given, as liqua acetate of ammonia, in two- 

 ounce doses every four hours. An ounce of sweet spirits of nitre 

 is useful. Three-drachm doses of potassium iodid may be given 

 twice a day during convalescence. It is safer, as a general thing, 

 to make a judicious use of stimulants from the beginning; nitrous 

 aether, one ounce; sal. acetate of ammonia, one ounce, diluted in 

 one pint of water, is the best and should be given every four 

 hours. 



PLEURISY. 



This consists of an inflammation of the pleura. When the 

 pleura and the lung substance itself are inflamed, we call it 

 pleuro-pneumonia. The pleura is the serous membrane that lines 

 the thoracic cavity and covers the viscera of the thorax. 



The causes are similar to those of pneumonia. Nearly a" 

 cases of pleurisy terminate in effusion of serum, constituting lir. 

 ited hydrothorax. 



Pleurisy may be double or single, but generally it is single, and 

 confined to the right side. 



Sy.mptoms. — It is characterized by a chill at the beginning. 

 There is coldness of the body, a wiry pulse, and a painful cough. 

 The animal becomes stiff and sore, and if approached or turned 

 around suddenly he will groan. During the act of respiration, 

 the ribs are fixed, a hollow line extends along the inferior border 

 of the false ribs. The muscles over the affected part quiver, and 

 great soreness will be observed. On auscultation, a crepitating 

 sound can be heard, caused by the pleural membranes moving 

 over each other. The cough accompanying pleurisy is of sup- 

 pressed character.
