only retreat from the skin to infest some more vital 

 internal organ : but we always consider that such 

 an evanescent attack had subsided through its own 

 weakness, for nothing ever came of it after thus 

 retreating spontaneously. Like surfeit in man, 

 these tumours are attended with a pricking pain, 

 the animal appearing restless, flinching from the 

 touch, and looking round sharp at his legs and 

 sides, as if he were spurred trivially. Whenever he 

 can bring the parts to bear against the stall, the 

 bail, or the wall, the animal will rub violently, 

 until the hair comes off, and the skin is raw. In- 

 stead of tumours that emit a sharp, acrid, and 

 stinking humour, like grease, a dry scurf appears, 

 resembling scabs, and this is mange in some ani- 

 mals ; whilst other subjects exhibit no eruption 

 whatever, though every hair is affected in a small 

 degree, the skin becomes dry, and he is then hide- 

 bound . 



Cure. — Surfeit is easily removed by a cooling 

 purgative ; but if the pulse be high, he should be 

 bled also. Promote perspiration by means of the 

 diaphoretic ball recommended at page 395, with 

 the same precautions as are there set down. If 

 the animal be fat, he must be reduced ; give bran 

 mashes, sodden oats, and good exercise ; and should 

 moisture be found to discharge from the skin, wash 

 it with the 



Surfeit Wash.
