Δῆλον δ’ ἐκ τούτων καὶ διὰ τίν’ αἰτίαν τοῖς μὲν ἀναπνέουσι τῶν ζῴων ἀποπνίγεσθαι συμβαίνει ἐν τῷ ὑγρῷ, τοῖς δ’ ἰχθύσιν ἐν τῷ ἀέρι· τοῖς μὲν γὰρ διὰ τοῦ ὕδατος ἡ κατάψυξις γίνεται, τοῖς δὲ διὰ τοῦ ἀέρος, ὧν ἑκάτερα στερίσκεται μεταβάλλοντα τοὺς τόπους. Ἡ δ’ αἰτία τῆς κινήσεως τοῖς μὲν τῶν βραγχίων τοῖς δὲ τοῦ πνεύμονος, ὧν αἰρομένων καὶ συνιζόντων τὰ μὲν ἐκπνέουσι καὶ εἰσπνέουσι τὰ δὲ δέχονται τὸ ὑγρὸν καὶ ἐξιᾶσιν, ἔτι δ’ ἡ σύστασις τοῦ ὀργάνου, τόνδ’ ἔχει τὸν τρόπον.
