MEDICINES. 4t)() 



ao not act so quickly or so extensively ; therefore they should 

 not be used in acute inflammation of the lungs or bowels, or any 

 vital part. When the inflammation, however, although not in- 

 tense, has long coutinued, rowels will be serviceable by produ- 

 cing an irritation and discharge that can be better kept up than 

 by a blister. As promoting a permanent, although not very con- 

 siderable discharge, and some inflammation, rowels in the thighs 

 are useful in swelled legs and obstinate grease. If fluid is thrown 

 out under the skin in any other part, the rowel acts as a per- 

 manent drain. "When the sprain of the joint or the muscles 

 oi the shoulders is suspected, a rowel in the chest will be ser- 

 viceable. The wound caused by a rowel will readily heal, and 

 With little blemish, unless the useless leather of the farrier has 

 i»een inserted. 



Sal Ammoniac, — See Chloride of Ammonia. 



Salt, common, see Sodh Chloridum. 



Secale cornutum. Ergot of Kye. — This is well known to be 

 an excitant in assisting parturition in cattle, sheep, and dogs. It has 

 been used with success in the mare by Mr. Richardson, of Lin- 

 cuin. It should only be applied in difficult cases, and the dose 

 siiould be two drachms, combined with some carminative, and 

 gj ven every hour. 



Sedatives, — are medicines that subdue irritation, repress spas 

 modic action, or deaden pain. We will not inquire whether they 

 ace first as stimulants : if they do, their effect is exceedingly tran- 

 sient, and is quickly followed by depression and diminished action. 

 Digitalis, hellebore, opium, turpentine, are medicines of this 

 kind. Their effect in different diseases or stages of disease, and 

 the circumstances which indicate the use of any one of them in 

 preference to the rest, are considered under their respective titles.* 



Soda. — The Carbonate of Soda is a useful antacid, and prob- 

 ably a diuretic, but it is not much used in veterinary practice. 

 The Chloride of Soda is not so efficacious for the removal of un- 

 pleasant smells and all infection as the chloride of lime ; but it is 

 exceedingly useful in changing malignant and corroding and de- 

 structive sores into the state of simple ulcers, and, in ulcers that 

 are not malignant, it much hastens the cure. Poll-evil and fis- 

 tulous withers are much benefited by it, and all farcy ulcers. It 

 is used in the proportion of one part of the solution to twenty-four 

 of water. 



SoDii Chloridum, Common Salt, — is very extensively em- 

 ployed in veterinary practice. It forms an efficacious aperient 



* Note hy Mr. Spooner. — Sedatives. — To the list enumera^€:d in the text' 

 may be added the extract of belladonna, or the deadly nightshade, which is 

 Ejiven in doses of two drachms.
