110 SHEEP DISEASES. 



as fifteen hundred sheep have succumbed within 

 a few days, during a season of wet or cold weather. 



Treatment: In no disease are hygienic measures 

 more important, and when these cannot be given, 

 attempts at medical treatment are useless. Cam- 

 phor and creosote, such as has been suggested for 

 nasal catarrh, or spartein sulphate, given in five- 

 grain doses, hypodermatically, may be given. 



6. Pleurisy. 



Inflammation of the pleura; pleuritis. 



This affection is a common sequela of pneu- 

 monia, 



Symptoms: The manifestations are quite char- 

 acteristic. The animal grunts as it breathes, and 

 the flanks are more used than the chest. There is' 

 a loss of appetite and suspension of rumination. 

 On percussion, dull sounds are heard on the lower 

 edge of the chest. 



Treatment: When this disease has become 

 established, therapeutic measures are more or less 

 useless. In valuable animals, fifteen grain doses 

 of potassium iodid may be given three times a day. 

 The prognosis is grave.
