OPHTHALMIC.— The first branch of the Trigeminus passesthrough the Cavernous Sinus, and enters the orbit through thesphenoidal foramen. While in this foramen it divides intothree branches, called Nasal, Frontal, and Lachrymal. The Nasal branch of the Ophthalmic ascends towards the internalface of the orbit. It gives off a branch called Ramus Ciliaris,which joins the Lenticular Ganglion, which was referred toin the description

It gives off a branch called Ramus Ciliaris,which joins the Lenticular Ganglion, which was referred toin the description of the third pair. Afterwards it gives offa branch called Internal Nasal, which enters the cavity ofthe cranium through the anterior orbitary or ethmoidal fora-men, and then passes into the nose, through the most anteriorperforation of the cribriform plate, descending in a grooveupon the under surface of the nasal bone to the Schneiderianmembrane. The remainder of this nerve is spent upon themuscles, eye-lids, conjunctiva, &c. lA/eryfs Plate 3 f. Trigeminus Super/. PetrousDeep Petrous. HI. del r Puva!

It dividesinto filaments, one of which emerges from the orbit throughthe supra-orbitary foramen, and the other passes out near thetrochlea. It supplies the muscles and integuments of theforehead and scalp. T ll e L il ( ll r y HI a I traverses the external side of the orbit, and sup-plies the lachrymal gland. It sends some filaments also tothe surrounding structures. 2. SUPERIOR MAXILLARY . — This nerve leaves the Ganglion ofCaster, and, passing through the Foramen Kotundum of theSphenoid Bone, enters the pterygo-maxillary fossa. It dividesinto two large branches, called Infra-orbital and Pterygo-palatine. The Illfra-orbital passes forwards, and gives off a branch calledPosterior dental, which supplies three molar teeth, and a partof the antrum and the gums. The infra-orbital, in its cours
