514 PHARMACOPCEIA. 



CARDIACS. (See Cordials,) 

 CAUSTICS. Substances which burn or 

 destroy any part of the body to which they 

 are applied. They are of great use in ve- 

 terinary practice, for destroying unnatural 

 excrescences, cleansing foul ulcers and si- 

 nuses, so as to bring them to a healthy state, 

 and curable by more simple applications. 

 Caustics may be divided into liquid and so- 

 lid, strong and mild. The mild caustics are 

 called also escharotics, and are more useful 

 than the stronger caustics, which are too 

 violent in their action in many cases, and 

 often require to be diluted with water, spi- 

 rit, or unctuous substances, according to 

 the nature of the case.
