(Chapter 12) Footnote 72:

Vesalius cites the eleventh chapter of Book One of Aristotle's Historia animalium. See 492a19ff.: “There is no passage from [the ear] to the brain, but there is a passage to the roof of the mouth, and a blood-vessel passes to it from the brain” (Loeb tr. by A. L. Peck, who notes “this is the first recorded reference to the Eustachian tubes, rediscovered by Bartolomeo Eustachi (1520-1574), whose work was published in 1714.”)
