(Chapter 9) Footnote 19:

The last two sentences are omitted from the 1555 edition; the revised introduction runs as follows: “The second figure, representing the base of the skull and the palate, sets forth that surface of the bones of the upper maxilla which was not visible in the preceding figure. Though it is marked with many characters, we shall explain only those which have to do with the account of the bones of the upper maxilla.”
