Chap. X. Of the Bones proper to the upper Jaw.

THe Bones proper to the upper Jaw, are eleven on each side five, and one without a fellow.

The first being in a manner triangular, doth make up the lower part of the socket of the Eye, the lesser Eye-cor∣ner▪ and part of the Os jugale and of the Cheek-bone.

The second makes the greater Eye-corner where there is an hole which passes into the Nostrils, by which a Ca∣runcle is placed.

Here those Imposthumes are made which they call aegi∣lopas, which if they be unskilfully or negligently hand∣led, they pierce to the Bone, and cause the Fistula Lachry∣malis.

This is a little Bone, and the least among the upper Jaw-bones, Thin, Transparent, Loosly, Adhereing, so that it is easily broken and lost: and therefore 'tis seldom found in Skuls dug out of the Earth.

The third is a very great one, by which are constituted the large region of the Palate, and the great lower socket

containing the Teeth. It hath large Cavities (and holes through which vessels pass) on both sides remarkable, both for to make it lighter, and that it might contain Marrow to nourish the Bones and the upper Teeth. Others say to help to frame the Voyce. In Children they are not hollowed til after some years, and they are then cover'd with a very thin Membrane.

The fourth with its companion, doth constitute the up∣per and more eminent boney part of the Nose.

It is thin, hard, solid and quadrangular.

And these two external bones of the Nose are divided with a Suture. Within they are rough, that the Gristles of the Nose, may be the better fastened.

There is another inner bone (which is the third of the Nose) cleaving to the process of the Os spongiosum, which is called Septum narium because it distinguishes the No∣strils.

The fift is seated at the end of the Palate, where the holes of the Nostrils go into the Throat or Fauces. They

are distinguished one from another by the middle Suture of the Palate, and make the hinder part of the Cavity of the Palate and Nostrils, they are thin, solid and broad.

To these ten Columbus ads the eleventh, like a Plough, the inmost and middlemost above the Palate, shutting the lower part of the Nostrils, like a partition wall.
