ὁμοίως δὲ ὅσων οἱ φλοιοὶ περιαιροῦνται καθάπερ ἀμπέλου κέδρου φιλύρας καὶ ὅλως τῶν φλοιορραγῶν. αὐτὴ γὰρ ἡ φύσις ἐνταῦθα ἔοικεν ἐπιδεικνύναι τὸ συμφέρον ἀφισταμένη καὶ ἀλλότριον ποιοῦσα· τὸ δ᾽ ἀλλότριον ἅπαν βλαβερὸν ὥσπερ καὶ τὸ αὖον. καὶ ἐπὶ τῶν ἄλλων δὲ τὸν αὐτὸν τρόπον ὅπου τις ἰδιότης οἰκεία πρὸς τὴν φύσιν. καὶ περὶ μὲν δένδρων ἐκ τούτων θεωρητέον.
