but in 1.0 other case should they obtain a place in the stable, or

Corrosive Sublimate. — See under Hydrargyrum. 



Cream of Tartar. — See under Potash. 



Creasote, — has very lately been introduced into veterinary 

 practice, and is much valued on account of its antiseptic proper- 

 ties. It is obtained by the destructive distillation of various sub- 

 tances, as pyroligneous acid, tar, wood, smoke, &c. Pure crea- 

 sote is colorless and transparent ; its odor is that of smoked meat, 

 and its taste is caustic and burning. It coagulates the albumen 

 of the blood, and hence has been lately employed in stopping haer- 

 morrhages. It acts very powerfully on the general system, and 

 :iuickly destroys small animals.. Professor Morton gives a very 

 interesting and faithful account of it. It is, according to him, 

 both a stimulant and a tonic. In an undiluted state it acts as a 

 caustic. When diluted it is a general excitant and an antisep- 

 tic. In the form of a lotion, a liniment, or an ointment, it has 

 been useful in farcy and glanders, also in foot-rot, canker, and 

 thrush, — mange, carries excessive suppuration, and the oppression 

 of fungous granulations. As a caustic it acts as a powerful stim- 

 ulant, and is an antiseptic. 



Creta Preparata, — is principally used in combination with 

 catechu and opium in cases of super-purgation. All adventitious 

 matters are removed by washing, and the prepared or pulverized 

 chalk remains in the form of an impalpable powder. It is usu- 

 ally administered in doses of two or three ounces. It is externally 

 applied over ulcers that discharge a thin and ichorous matter. 



Croton Seeds. — The croton-nut has not been long introduced 

 into veterinary practice, although it has been used from time im- 

 memorial by the inhabitants of India as a powerful purgative. 

 An oil has been extracted from it, and used by the surgeon ; the 

 meal is adopted by the veterinarian. It is given in doses from a 

 scruple to half a drachm, and from its acrid nature, in the form 

 of a ball, with an ounce of linseed meal. When it does operate 

 the effect is generally observed in six or eight hours, the stools 

 being profuse and watery, and the patient frequently griped. On 

 account of its speedy operation, it may be given in locked-jaw 

 and staggers : and also in dropsy of the chest or belly, from the 

 watery and profuse stools which it produces ; but it is often un- 

 certain in its operation, and its griping, and the debility which 

 it occasions, are serious objections to it as common physic. 

 When placed on the tongue of the horse in quantities varying 

 from twenty to forty drops, it produces purging, but the mem- 

 brane of the mouth frequently becomes violently inflamed. This 

 likewise happens, but not to so great a degree, when it is given 

 in the form of a drink, or in a mash.
