 (ESOPHAGUS, ETC. 



Wounds of the lips call for no special notice, further than that 

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

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

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

 a lip is partly cut, with the divided portions hanging loosely, to 

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

 bringing them together with sutures, and retaining them in ap- 

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

 practitioner the importance of never removing any portion of 

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

 and rather 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. 



tumour of THE LIP. 



A tumour sometimes forms on the lips; at first firm and 

 solid to tlie touch, of a variable size, occurring either spon- 

 taneously or as the result of a sting, and which in a day or 

 two suppurates and bursts. It requires little treatment except 

 fomentations.
