AND PHARJIACOPCEIA. 457 



Place them in a large gallipot, or open phial, and take care to 

 avoid the noxious fumes -which arise. When the quicksilver is 

 perfectly dissolved, and the mixture cold, it may be put into a 

 small phial and corked. 



Remark. — This is a strong and efficacious caustic; it is a 

 certain remedy for the foot-rot in sheep, and often effectual in 

 canker of the horse's foot, provided these complaints are properly 

 managed in other respects. It is sometimes mixed with melted 

 hog's lard to form a strong detergent ointment, or diluted with 

 water. 



No. 3. Nitrous acid 1 oz. 



Verdigris ^ oz. — Mix. 



This caustic is very little, if at all, inferior to the former, and 

 applicable to the same purposes. 



No. 4. Muriate of antimony, or butter of antimony. 



No. 5. Muriate of quicksilver, or sublimate... 1 dr. 

 Muriatic acid 2 drs. 



Remark. — This is a very powerful caustic, and always re- 

 quires dilution. Yellow arsenic, mixed with lime and grease, 

 or egyptiacum, or hog's lai'd, is sometimes used as a caustic to 

 destroy warts, or cure fistula or poll-evil. 



MILD CAUSTICS, LIQUID. 



No. 1. Solution of blue vitriol.

CAYENNE PEPPER. See Capsicum. 



CERATE. — Ceratum. A term given to certain ointments 

 or salves, in which icax is an ingredient. It is necessary that 

 the oils or fat with which they are composed be perfectly fresh, 

 and preserved in this state. 



CERUSE. — Plumbi Subcarhonas. This is a carbonate, or 

 white oxide of lead, and is commonly called white lead. It is 

 a very st'-ong astringent, and is sometimes 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 be found more useful if used in the form of 

 a fine powder. (See Lead.) 



CETACEUM. Spermaceti. This is demulcent and emol- 

 lient, but is not used internally in veterinary practice. Its chief 

 use is in the formation of ointments.
