Wounds of the lips call for no special noticcTTurthcr^tharTlTinl 

 tliey are to be treated upon the conservative method ; that is 

 to say, an endeavour must always be made to bring, about the 

 umon of the divided parts. It is a very common practice,* when 

 a lip is partly cut, with the divided portions haiigingi^loosely,'to 

 remove them with a sharp pair of scissors or knife,- instead of 

 bringing them together with sutures, and retaining I thcm'inTap* 

 position till they are united. I want to impress upon tlic young 

 practitioner the impoiiance of never removing any. portion of 

 injured lips until he sees that their reunion is an impossibility; 

 and ratlier than cut them off, he should allow them to be separ- 

 ated by the process of sloughing ; for a lip mutilated by meddling 

 surgery remains a permanent blemish, leaving the teeth exposed 

 and the powers of prehension greatly interfered with.
