RUNNING THRUSH. 



A RUNNING frush, or thrush, is an ulcer in 

 the frogs of horses' feet, from the cleft of which 

 it discharges a corrosive fetid matter. Horses 

 subject to this disease have fleshy heels, ragged, 

 or rotten, frogs, which are incapable of giving 

 protection to the more sensible parts of the feet, 

 whence arises that tenderness in the foot we so 

 frequently see. 



The method of cure must j^r^^ be to pare away 

 the putrid, ragged, or rotten part of the frog ; tlien 

 rub the part with the astringent wash (No. 146, 

 p. 195) ; after which lay on a small pledget of 

 tow, dipped in egyptiacum, upon the thrush, and 

 a pledget dipped in tar, over the whole ; splinter 

 it fast down under the shoe. Repeat the dressings 

 once a day until cured : the astringent wash must 

 be continued for some time after, by way of hard- 

 ening the part. If this method fail, the following 

 must be used.
