Gustatory impulses from the anterior end and lateral edges of the tongue are conveyed by the lingual (gustatory) brajftch of this nerve.

The subject can not be regarded as quite settled. Tactile sensibility in the tongue is very pronounced, as we have all experi- enced when a tooth, etc., has for some reason presented on unusual surface quality, and become a source of con- stant offense to the tongue. The ganglia of the fifth nerve, so far as the functions of their cells are concerned, are enigmatical at present. They are doubtless in some sense tro- phic at least. With each of these are nerve connections (" roots " of the gan- glia), which seem to contam different kinds of fibers. These ganglia are connected vrith the main nerve-centers by both afferent and efferent nerves, »nd also with the sympathetic nerves themselves. Some r^ard the ganglia as the representatives of the sympa- thetic system within the cranium. I. The Ciliary (Ophthalmic, Len- ticular) Oanglion.—lta three roots are : 1. From the branch of the third nerve to the inferior oblique muscle (motor root). 2. From the nasal branch of the ophthalmic division of the fifth. 8.
