and internal recti, and inferior oblique) and the 

 levator muscle of the lid. 



4. The Pathetic Nerve (IV.) passes through the 

 sphenoidal fissure to another muscle (superior 

 oblique) of the eyeball. 



5. The Trigeminal Nerve (V.), soon after it 

 emerges from the brain, enlarges into the Gasse- 

 rian ganglion. It then separates into three divis- 

 ions : the ophthalmic, which passes through the 

 sphenoidal fissure and is distributed to the lachry- 

 mal gland, upper lid, and conjunctiva of the eye, 

 and the skin of the nose and forehead ; the max- 

 illary, which passes through the foramen rotun- 

 dum and supplies the lower eyelid, side of the 

 nose, upper teeth, and the roof of the mouth and 

 pharynx ; and the mandibular, which passes 

 through the foramen ovale and supplies the mus- 

 cles and skin of the side of the head, muscles of 

 mastication, lower lip, teeth, salivary glands, and 

 inside of the mouth. 



6. The Abducens Nerve (VI.) passes through the 

 sphenoidal fissure and supplies muscles of the eye- 

 ball. 



7. The Facial Nerve (VII.) passes through the 

 stylo-mastoid foramen and supplies the muscles of 

 the face and head. 



8. The Auditory Nerve (VIII.) enters the inter- 

 nal auditory meatus and is distributed to the in- 

 ternal ear. 



9. The Glosso-pharyngeal Nerve (IX.) emerges
