518 THE IMPROVED ART OF FARRIERY. 



CATHARTICS. 



Whatever excites the intestines to a more early, a 

 more frequent, and a more copious discharge of their 

 contents, may be termed a cathartic or purge. If this 

 effect be intended to be produced in a slight degree 

 only, the article effecting it is termed a laxative. The 

 principal cathartic in veterinary practice, is aloes. 



Castor oil, calomel, and neutral salts, may be con- 

 sidered as laxatives. 



CERATES. 



Are ointments of a dry healing nature ; the principal 

 of which is calamine or Turner's cerate. 



Burgundy Pitch, 



Differs but little from resin, and will be found un- 

 der that head. 



ALOES. 



There are two kinds used in horse practice, the Bai - 

 badoes and the Cape. The Socotrine preferred by the 

 human surgeon are very uncertain in their effect on 

 the horse. Of the Barbadoes and the Cape, the first 

 are much to be preferred.
