LEPUS. 391 
A description of the nerves cannot be entered into 
here, but a few of the more important are to be seen in the 
neck. (Plate XIII.) In this region we have already noticed 
the carotid arteries, the internal and external jugular veins, 
the oesophagus, trachea and phrenic veins. Just internal to 
the phrenic nerve and close beside the carotid artery runs

the vagus (or tenth cranial). It has a slight ganglionic 
swelling, just opposite the larynx, and here gives off two 
branches—the anterior laryngeal, which runs into the larynx, 
and the depressor, which is a long delicate nerve running 
backwards to the heart dorsally to the carotid. The vagus 
is continued backwards into the thoracic cavity and along 
the cesophagus to the stomach. It gives off the recurrent
