The EXPLANATION of the Twelfth TABLE, In Folio 418.

This Table, delineated by Willis, shews the Originals of the Nerves of the Fifth and Sixth Pair (according as he num∣bers them) and the Roots of the Intercostal Nerve, pro∣ceeding from them: Also the Originals of the same Inter∣costal Nerve, and the Vagous Pair, and of the Nerve pro∣ceeding from the Spine to the Vagous Pair, carried along to the Region of the Ventricle. Moreover, it represents the Originals and Distributions of the Nerves of the Seventh, Ninth, and Tenth Pair, and of the Nerve of the Dia∣phragma. In the same also are described the Originals of the Vertebral Nerves, and their Communications with the Former, as they are to be found in Men. But it is to be observed, that Willis, in this Table, does not fol∣low the Ancient (which we observe in our Descripti∣on) but his own new Computation of the Number of the Nerves. VVhence it comes to pass, that what we in our Text call the Third, he calls the Fifth; what we the Fifth, he calls the Seventh; what we the Seventh, he calls the Eight Pair.
