    briform plate of the ethmoid bone ;—two frontal or pituitary sinuses within the bone, above the root of the nose; they are always separated by a thin bony partition, and open by two small holes into the nostrils, of which they form a part: -——two orbitar cavities, in which are two depressions for the situation of the lachrymal gland;—a notch in each superci- liary ridge for the trochlea of the superior oblique muscle ; —a superciliary foramen, through which passes a small ar tery from within the cranium, together with a branch of the fifth pair of nerves, to be distributed to the muscles and in- teguments of the forehead; often a notch only is seen, and sometimes there are two foramina on one side, and one on the other;—the anterior orbitar foramen, which gords a passage to a branch of the ophthalmic artery, and a small twig of the fifth pair of nerves into the nose; this foramen is sometimes formed by the junction of the ethmoid ‘bone with the frontal;—the posterior orbitar foramen, which is smaller than the former, and deeper in the orbit ;—a de- pression, behind the middle of the superciliary ridge, for the situation of the lachrymal gland;—the foramen cecum, situated below the beginning of the internal frontal spine; —slight furrows and ridges on the orbitar processes ecta- sioned by the convolutions of the brain. : _ Connexion. The frontal bone is connected with the two parietal, by means of the corona] suture; with the two ossa nasi, the two superior maxillary bones, and the two lachry- mal bones, by means of what is called the transverse suture; with the sphenoid bone by means of harmony, called har- monia sphenoidalis; with the ethmoid bone by harmonia eth- moidalis; and withthe os jugale by means of suture. The use of the frontal bone is to constitute the forehead pituitary sinuses, part of the orbit, and to contain and de- fend the anterior lobes of the brain,
