238 THE PRACTICE OF VETERINARY MEDICINE. 



hair nicely from the parts, use fomentations, etc., freely. 

 If there is a small opening, probe it, and if deep, cut it right 

 out, and be particular after it is cut out to have the horse's 

 head kej^t elevated, as it will assist materially in treatment. 

 This condition is not as simple a condition as it appears to 

 be. AVhite lotion may be used with great benefit ; plumbi 

 acetas, in solution ; to which, if desired, a small quantity of 

 tannin may be added. If it is necessary to work the 

 animal the collar should be well padded, and should be 

 thoroughly cleansed and dried every night. A solution of 

 plumbi acet. is better than the common one of sodium 

 chlorid, which, however, is of considerable benefit. 



Hair Sinuses. — We sometimes meet with a well-marked 

 sinus extending into the neck, or about the region of the 

 shoulder, and which is lined with hair throughout its whole 

 extent. They are readily discoverable, as they are easily 

 seen. 



Treatment. — The treatment consists in removal by means 

 of the knife, carefully dissecting them out, after which 

 treat as an ordinary wound. 



Saddle Galls. — These are the same as collar galls, and are 

 treated in the same way. 



Sitfasts are caused by badly-fitting saddles, collars, etc. 

 It may be the cause of a troublesome little sore that will not 

 readily heal, but breaks out on working the animal. 



Treatment. — Do not waste time with poultices, caustics, 

 etc., but dissect the dead skin out, and afterwards use 

 poultices, caustics, astringents, etc., to allay irritation. 



FISTULOUS WITHERS. 



A fistula is characterized by having two openings, but 

 fistula of the withers has only one opening, hence is said 

 to be an incomplete fistula, as the other end is a blind 

 pouch.
