 to sleep in will be found necessary to effect improvement. Par- 

 ticular attention should be given to the pastures, to be certain 

 that no causes exist there which are responsible for the trouble. 



Rheumattstn

 three forms — acute, sub-acute, and chronic. The mature sheep 

 are easily affected with this condition; it seems, however, to fre- 

 quently attack lambs, generally in the acute form. The predis- 

 position for this disease has always been looked upon as heredi- 

 tary, and in every case where mal-nutrition of the body is present 

 rheumatism is frequently observed. As it occurs in mature ani- 

 mals it is supposed to follow, some debilitating disease. The ex- 

 citing cause in sheep and lambs, in most cases, seems to be expos-

Symptoms. 



First notice lameness. The animal is feverish; the affected 

 joint or part feels hot to the touch and frequently commences to 

 swell; the pulse is hard and rapid; the swelling feels firm and
