Note w — BOOK IV.

I do not confine the Labyrinth to the Canales Semicirculares, or any other Part, as the elder Anatomists seem to have done, who by their erroneous and blind Descriptions seem not well to have understood there Parts; but with those much more curious and accurate Anatomists, Monsieur de Vernay, and Dr. Valsalva; under the Labyrinth, I comprehend the Canales Semicirculares, and the Cochlea, together with the intermediate Cavity, called by them the Vestibulum.
