288 BLOOD DISEASES. 



by the deposition of porcelaineous deposits between the heads of 

 the bones constituting the joint, in which event the lameness be- 

 comes permanent. 



In sheep the neck and loins are frequently attacked, making 

 the animal stiff and weak in its back; if the trouble locates in 

 the neck, it will be carried bent to one side, or the disease may 

 suddenly leave the neck or other parts and locate in a limb, the 

 ability to leave one part of the body only to at once re-appear in 

 another being termed metastasis. 



Affected sheep generally assume the recumbent position. 

 The acute form of rheumatism may terminate fatally. In 

 such an event, a metastasis to the heart is generally the cause. 

 This is not frequent, however, as the disease has a tendency to 

 become chronic, the animal remaining stiff, with a liability to 

 relapse to the acute condition during cold weather. 



Crcatmcnt. 



Acute cases of rheumatism require good hygienic surround- 

 ings if a cure is to be expected. The affected sheep should have 

 warm, dry quarters and nourishing food. Internally salicylate 

 of soda in fifteen grain doses should be administered twice daily, 

 or potassium iodide can also be given with good results. Ex- 

 ternally to the inflamed parts a stimulating liniment should be 

 applied, such as 



Strong water of ammonia 2 ounces 



Spirits of turpentine 2 ounces 



Linseed oil 8 ounces 



Chronic rheumatism incapacitates a sheep for further use- 

 fulness in the flock. Animals so affected should be destroyed, 

 or, if in good condition, should be sold to the butcher.
