CHAP. X. Of the holes of the inner Basis of the Scull.
IN the first place are reckoned the holes of the bone Ethmoides; then those of the optick nerves; thirdly of the nerves moving the eyes. Fourthly of that portion, of the nerves, of the fourth conjugation which goe to the temporall muscles. Fifthly are reckoned, these holes scarse visible, scituate under the pituitary glandule, by which the spettle is evacuated. Sixthly that hole which is in the wedge bone made for the entrance of the internall sleepy Arteries, composing the wonderfull Net, and then passing into the braine by a great slit. That perforation which we reckon in the seventh place is commonly double, made for the entrance of one of the branches of the internall Iugular veine. The eight hole is some-what long, of an ovall figure, by which, part of the third conjugation and all the fourth conjugation passes forth. The ninth are the auditory passages. The tenth are very small holes, and give way to the veine and artery going to the auditory passage, above the for a men coecum. In the eleaventh place are reckoned the perforations which yeild pas∣sage forth to the sixth paire of nerves, to part of the sleepy Arteries, and of the inter∣nall jugular. In the twelvth those which yeild a way out to the seventh conjugation; The great hole of the Nowle bone through which the spinall marrow passes is rec∣koned the thirteenth. The fourtenth is that, which most commonly is behinde that great hole, by which the Cervicall veines and arteries enter in.
