Setons. 



Setons are similar in their action to rowels, and are used for 

 much the same purposes. They are usually made of broad white 

 tape. In inserting a seton, the skin is cut with the rowelling 

 scissors as above. A seton needle, which should be large and well 

 polished, is passed in and pushed under the skin as far as is neces- 

 sary ; another cut is then made in the skin, through which it is 

 passed out; the needle in its course should separate the skin on 

 each side from its cellular attachments. The lower opening 

 should always be so placed that the matter will have a dependent 

 outlet. The ends of the seton should be tied to circular j)ieces of 

 leather, so as to prevent its being pulled through. It is necessary 

 to wash it frequently with warm water, and pull it up and down 

 often, to keep it open, dressing it occasionally with digestive oint- 

 ment to keep up the discharge. 



The Rowel. 



Rowels are used as counter-irritants in treating deep-seated 

 inflammations ; and whenever any morbid disease is to be stopped, 

 as in grease and in thrushes, they have long been favorite reme- 

 dies among horsemen. 



In applying a rowel, the skin is to be taken up between the 

 finger and thumb, and a cut is made in the skin with the rowel- 

 ling scissors, and with the hook on the handle of the scissors it is 

 separated from its cellular connections for about two inches, and 

 a dossil of tow, or a circular piece of leather, with a hole in it, pre- 

 viously dipped in digestive ointment, is inserted, which must be
