usually selected for the operation. The vein .being raised, and the 

 hair smoothed down by the moistened finger, the star of the fleam 

 is placed in line 

 with the course of 

 the vein, with, one 

 smart tap of the 

 blood-stick the 

 skin and cbats of 

 the vein are punct- 

 ured, and the 

 blood will flow. 

 When sufficient 

 has been ab- 

 stracted, the 

 edges of the 

 wound should be 

 carefully taken to- 

 gether, and hairs 

 and clot carefully 

 wiped away; a small pin jis passed through them, and a little tow 

 wound round it, and the point of the pin cut off. The head should 

 be tied up for a few hours to prevent his rubbing the pin off. 



SETOlfrS. 



Setohs 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 roweling 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 y 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 pieces 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 ointment to keep up the 

 discharge.
