SWELLITfG OF THE SHEATH. 447 



having minute vessels passing towards it lohich present a venous 

 character conjested with blood having a venous appearance, and 

 which bleed upon the slightest irritation. 



Teeatment. — Having satisfactorily determined the disease 

 to be Glanders, the best course to pursue is to destroy the 

 animal affected forthwith. The liability of the malady to spread 

 to other horses, and the great danger of its being communi- 

 cated to human beings, renders the destruction of the patient 

 imperative. 



In conclusion, I may observe, that in my opinion hundreds 

 of cases of Ozena have been mistaken for Glanders, and the 

 animals destrbyed in consequence. See Article " Ozena," 

 pag6 238. 



SWELLING OF THE SHEATH. 

 Horses are sometimes affected with swelling of the sheath. 

 It is a condition of the parts which frequently arises from 

 debility, and also as a result of the animal being confined for 

 some time to the stable, either in consequence of sickness ; or 

 from the want of work. The most common cause, however, is 

 uncleanness of the sheath. 



Teeatmeistt. — Examine the organ, and if its interior be in 

 a dirty condition, cleanse it thoroughly with warm water and 

 soap. Should the affection arise from debility, or confinement 

 of the horse to the stable from any other cause, cleanse out the 

 sheath, and exercise the animal daily. Attend also to the diet 

 of the horse. 



Por further particulars as to the diet of convalescent 

 patients, see Section YI., page 108.
