12 οἱ δʼ ὄρνιθες τοὺς πόρους μόνον ἔχουσι διὰ τὴν τού δέρματος σκληρότητα, καὶ τὸ ἔχειν μὴ τρίχας ἀλλὰ πτερωτὰ εἶναι· οὐκ οὑν ἔχει τοιαύτην ὕλην ἐξ ἧς ἂν ἕπλασε τὰ ὡτα. ὁμοίως δὲ καὶ τῶν τετραπόδων τὰ ῴοτόκα καὶ φολιδωτά· ὁ γὰρ αύτὸς ἁρμόσει καὶ ἐπʼ ἐκείνων λόγος. ἔχει δὲ καὶ ἡ φύόκη τῶν ζῳοτόκων οὐκ ὖτα ἀλλὰ πόρους ἀκοῆς, διὰ τὸ πεπηρωμένον εἶναι τετράπουν.
