 to a slight extent the duration of healing may be mate- 

 rially lessened.

Interrujpted. — Stitches passed at intervals through the 

 edges of the wound, and each tied separately. 



Uninterrupted. — Suture material passed successively and 

 continuously several times through the edges of the 

 wound alternately.

 their flat surfaces against the edges of the wound, which 

 they keep level and prevent from tearing. They are 

 retained by the thread sutures.
