πνεῖ δὲ τὰ πνεύματα τὰ ἀποκαίοντα περί γε τοὺς κατὰ τὴν Ἑλλάδα τόπους ἀπὸ δυσμῶν ὥσπερ ὁ Ὀλυμπίας ὁ ποιῶν ἄλλοθί τε καὶ ἐν Χαλκίδι τὸν καλούμενον καυθμόν· ἐν Θετταλίᾳ γὰρ ἀμφοτέρωθεν πνέοντες ἐκπηγνύουσιν· ἡ δ᾽ ὥρα τῆς πνοῆς μάλιστά πως περὶ τροπὰς ὑπὸ τὰς τετταράκοντα· τότε γὰρ καὶ ὁ ἀὴρ ὅλως ψυχρότατος. τὰ μὲν οὖν γινόμενα ταῦτ᾽ ἐστὶν, ἡ δ᾽ αἰτία σχεδὸν ὡς καθόλου γε εἰπεῖν φανερά· τὸ γὰρ θερμὸν ἐξελαυνόμενον ὑπὸ τοῦ ψύχους συνεξάγει καὶ τὸ ὑγρὸν ὥστε διαπνεῖσθαι.
