and posterior auricular lymphatic glands, and from thence join the cervical 

 glands. 



The Lymphatic Vessels of the Face are divided into two sets, superficial and 

 deep. 



The superficial lymphatic vessels of the face are more numerous than those of 

 the head, and commence over its entire surface. Those from the frontal region 

 accompany the frontal vessels ; they then pass obliquely across the face, running

with the facial vein, pass through the buccal glands on the surface of the Bucci- 

 nator muscle, and join the submaxillary lymphatic glands. The latter receive the 

 lymphatic vessels from the lips, and are often found enlarged in cases of malignant 

 disease of those parts. 



The deep lymphatic vessels of the face are derived from the pituitary membrane 

 of the nose, the mucous membrane of the mouth and pharynx, and the contents 

 of the temporal and orbital fossae ; they accompany the branches of the internal 

 maxillary artery, and terminate in the internal maxillary and cervical lymphatic 

 glands. 



The lymphatic vessels of the cranium consist of tAvo sets, the meningeal and 

 cerebral. The meningeal lymphatics accompany the meningeal vessels, escape 

 through foramina at the base of the skull, and join the deep cervical lymphatic 

 glands. The cerebral lymphatics are described by Eshmann as being situated 

 between the arachnoid and pia mater, as well as in the choroid plexuses of the
