Carefully remove the skin and expose (2) the layer of subcutaneous fat and fibrous tissue, in which 

 will be found the superficial nerves and vessels. To remove the skin, make a median incision from the 

 root of the nose to the external occipital protuberance, and a transverse incision from the lower end of 

 the mastoicl process on one side, over the vertex to the corresponding point on the opposite side. Con- 

 nect the ends of these incisions by horizontal incisions on each side, as follows : Beginning in front at 

 the root of the nose, make an incision along the superior lx>rder of the orbit to the outer angle of the
