Note x — BOOK IV.
Reading edition
In the semicircular Canals, two Things deserve to be noted. 1. That the three Canals are of three different Sizes, Major, Minor, and Minimus. 2. Although in different Subjects, they are frequently different; yet in the same Subject they are constantly the same. The Reason of all which, together with their Uses, Valsalva ingeniously thinks is, that as a Part of the tender auditory Nerve is lodged in these Canals, so they are of three Sizes, the better to suit all the Variety of Tones; some of the Canals suiting some, and others, other Tones. And although there be some Difference as to the Length and Size of these Canals, in different Persons; yet, lest there should be any discord in the auditory Organs of one and the same Man, those Canals are always in exact Conformity to one another in one and the same Man.
