Synonym. — Nejohritis.

 diuretic medicines, as turpentine, the resins, or cantharides; or, more

 upon the loins. Sometimes it is induced by the absorption of the active 

 princijile of cantharides from large blisters. 



Symptoms. — There is fever and colicky pains. The horse is restless 

 and uneasy, breathes short and rapidly, and perspires more or less freely. 

 He lies down cautiously and rises up again, as if suffering from colic; 

 but the abdomen, instead of being hard and distended as in that disease, 

 is tucked up. He sometimes stands with his legs wide apart, arches his 

 back, and straddles in his gait, though these are not to be considered as 

 peculiar symptoms of nephritis. Tendernes and wincing are evinced on 

 the application of pressure to the loins. The most sure evidence is total
