Illustration I is the left anterior quarter of the cerebral floor (from 142 NEW FACTOR IN TIC DOULOUREUX. Deavers Anatomy)—we note: (a) eyeball; (b) optic nerve; (c)chiasm; (d) posterior clinoid process, this with the sella-turcica form-ing the roof of the sphenoid sinus; (c. s.) cavernous sinus, forming thelateral wall of the sphenoid which contains (3rd) the 3rd or motoroculi, (4th) the 4th or trochlear, (5th) the 5th or trigeminus with(G G) the Gasserian ganglion at its decussation into its three branches:(o. n.) the ophthalmic, (s. m.) the superior maxillary and (i. m.) theinferior maxillary. Our idea of relation and proximity may be enhanced by illustrationII, a cross section of the cavernous sinus; in this drawing the nerves,

But in addition to the former isshown the carotid artery (c. a), the venous sinuses themselves (v. s.),the approximate side of the sphenoidal sinus (s. s.), and the pituitarybody (p. b.). The vidian nerve, the connecting branch between Meckels and thetympanic ganglia, traverses a canal very close to the lower side of thesphenoid and in a few anomalous cases this nerve has been found evenpassing through the sinus. A. WORRALL PALMER. 143 On account of the optic nerve—the chiasm—lying directly on theroof of the sphenoid, ophthalmologists find not infrequently that aneuritis of such nerve trunk and retinitis may be caused by diseaseof the sphenoid and posterior ethmoidal cells. In reasoning or investigating along similar lines Dr. Sluder, a rhinol-ogist, discovered and demonstrated that in like manner sphenoid andethmoid disease may affect the nerve fibers of the ophthalmic or firstand the superior maxil
