CASTOR OIL — CERUSS. 65 



Tiiirous acid. If a solid caustic is wanted, 

 nothino: is more convenient than tlie lunar 

 caustic (nitrated sil-vcr.) The milder caus- 

 tics are more frequently useful than those 

 we have mentioned, such as blue vitriol 

 fvitriolattd coppei^) red precipitate (red 

 nitrated quicksilver,) burnt alum, verdi- 

 gris, &c. 



The strong caustics are employed to des- 

 troy unhealthy or diseased parts ; but those 

 of the milder kind are very useful for the 

 purpose of bringing obstinate ulcers inta a 

 Irealing state, without any apparent destruc- 

 tion of parts. {S^e Caustics, Pharm.) 



CAYENNE PEPPER. (See Capsicum.) 



CENTAURY. This herb is a weak bitter, 

 and of no use in veterinary practice. 



CERATE. Aterm given to certain oint- 

 ments or salves, in which wa.v is an ingre- 

 dient- 



CERUSS, or White Lead. This is some- 

 times used in ulceration of the heels, when 

 the discharge is thin and acrimonious. 



It is generally made into an ointment with 

 hog's lard and oil ; but perhaps would b^ 

 found more useful if merely sprinkled on 

 the part in fine powder.
