CHAP. XIX. Of the Nerue of hearing, or of the fift Coniugation of the Braine.

THE fift Coniugation [Tab. 20, fig. 1, and 2, ^a Tab. 15, fig. 20. ^M] ariseth out of * 1.1 the Marrow of the Braine lengthened, where it ioyneth with the Cerebellum. [Table 25, figure 1, ⁱ] There his originall seemeth to be out of two Surcles or Nerues, the one softer the other harder, which together perforate the mem∣brane * 1.2 and passe to the stony bone.

This Nerue passeth through a notable writhen hole thrilled in the stony-bone, which * 1.3 they call the fift hole of the Temple bone, where it meeteth with that cauity which is com∣pared to a Conniborough and prepared for the Organ of hearing. Afterward the har∣der part falleth into the cauity called Tympanum or the Drum.

The softer part [Table 20, fig. 2, ^a] which is indeed Neruus auditorus the sinew of hea∣ring, * 1.4 accompanieth the former, and when it attaineth to the extremity of the aboue named cauity it is dilated like a membrane [Table 20, fig. 1, 2. Φ] and becommeth the speciall In∣strument of hearing, and in that place remaineth haply after the same manner that wee saide before the Organ of Smelling was extended.
