The Ninth Table. (Book 9)

Shews the beginnings of the fifth and sixth pair of Nerves, and the Roots of the Intercostal Nerve pro∣ceeding from them; moreover, the Origines and Branchings out of the same Intercostal Nerve and the wandring Pair, and of the accessory Nerve produced out of the Spine to the wandring Pair carri∣ed to the Region of the Ventricle. Besides, here are represented the beginnings and distributions of the seventh, ninth, tenth Pair of Nerves, and of the Nerve of the Diaphragma; also the beginnings of the Vertebral Nerves in their whole Tract from the Region of the Nerves inserted in the Praecordiae and Viscera are described, and their Communications with the former.
