Πάντων δὲ τῶν ζῴων κοινόν ἐστι τὸ περὶ τὴν κόρην ἐν τοῖς ὀφθαλμοῖς· ἔχουσι γὰρ τοῦτο τὸ μόριον στεατῶδες πάντα ὅσα ἔχουσι τὸ τοιοῦτον μόριον ἐν τοῖς ὀφθαλμοῖς καὶ μή εἰσι σκληρόφθαλμα. Ἔστι δ’ ἀγονώτερα τὰ πιμελώδη καὶ ἄρρενα καὶ θήλεα. Πιαίνεται δὲ πάντα πρεσβύτερα μᾶλλον ἢ νεώτερα ὄντα, μάλιστα δ’ ὅταν καὶ τὸ πλάτος καὶ τὸ μῆκος ἔχῃ τοῦ μεγέθους καὶ εἰς βάθος αὐξάνηται.
