THE GLOSSOPHARYNGEAL NERVE.

sense of taste, and also that those parts of the tongue to which the 

 glosso-pharyngeal is distributed present that sense in the most marked 

 manner. The inference which is usually drawn is that this nerve and the 

 lingual are both tactile and gustative, and this renders appropriate its 

 description in this place rather than among the nerves of special sense.
