Wounds] 336 [Wounds

 bone called the zygomatic ridge, resulting in the 

 formation of an abscess which will not heal 

 until the large molar tooth (which is situated 

 underneath the fistula) is removed, and then it

 situated in the neck ; as the result, a large 

 abscess often forms, and until the foreign body 

 has come away the wound, the result of the 

 bursting or lancing of the abscess, will not heal. 

 These cases are often very troublesome, as the 

 foreign body causing the mischief may be buried 

 very deeply in the tissues, and when small is 

 difficult to find even with the assistance of the 

 X-rays.

 but sometimes if the bleeding is very severe it 

 may not be possible to do it thoroughly at once,

 is severe haemorrhage this must be stopped as 

 soon as possible. As a rule, a thick pad of
