170 THE DISEASES OP THE HOUSE. 



Greasiness of the Skin. — Percivall describes the case 

 of a horse, recently returned from grass, which, while 

 shedding its coat in September, showed an exceedingly 

 greasy condition of the skin. It was washed with soft 

 soap, but in three days became greasy again. A week 

 afterward, after giving a fourth dose of physic, the ani- 

 mal was washed in water in which an alkali had been 

 dissolved.
