Note (4) — BOOK I.

4. Vessels, in the original, vena; which is used by our author as a general term for arteries and veins. In this place it is evident he means arteries; for mentioning the same opinion again, page 16, he says, At si sanguis in arterias transfusus; and he often speaks of the motion of the veins, where, it is plain, he intends the pulsation of the arteries. Arteria he uses to signify the wind-pipe, and likewise the sanguiferous arteries, as in chap. 1. of book 4. Circa guttur venae grandes, quae sphagitides nominantur; item arteriæ, quas carotidas vocant.
