 them. 



On the side of the head, in front of the ear, the superficial tern- on the side 

 poral vessels and nerve are to be traced upwards ; and, above the 

 zygomatic arch, the branches of the facial nerve which join an offset 

 of the superior maxillary are to be sought. 



Behind the ear the posterior auricular vessels and nerve, and behind ear, 

 below it branches from the great auricular nerve to the tip and back 

 of the pinna are to be found ; one or more offsets of the last should 

 be followed to its junction with the posterior auricular nerve. 



At the back of the head the ramifications of the occipital vessels, at the back 

 and the large and small occipital nerves should be denuded ; the
