περὶ δὲ τὸν Πόντον ὑπὸ τῶν πνευμάτων ἔκπηξις γίνεται, ὅταν αἰθρίας οὔσης (λεπίδες) καταφέρωνται· ταῦτα δέ ἐστι πλατέα ἄττα φερόμενα μὲν φανερὰ, πεσόντα δ' οὐ διαμένει· δῆλον δὲ ὅτι πῆξίς τις τῆς ὑγρότητος ἐν τῷ ἀέρι, καθάπερ τῆς πάχνης· ὅταν οὖν τοιοῦτος ὁ ἀὴρ προσπίπτων ὑπὸ τοῦ πνεύματος ᾖ καὶ ταῦτα συγκαταφέρηται, κατὰ λόγον ἡ ἔκπηξις γίνεται. Τὰ δὲ πνεύματα τοῖς μὲν ψυχροῖς φύσει τῶν τόπων, ὥσπερ ἐγχώρι' ἄττ' ἂν εἴη, καθάπερ ἐν τῷ Πόντῳ καὶ τῇ Θράκῃ, τοῖς δ' ἀλεεινοτέροις ἐκ τῶν ἔξωθεν ἡ ἐπιφορὰ, καθάπερ ἐν Εὐβοίᾳ· δηλοῖ δὲ καὶ ἡ φύσις, ὡς οὐκ αὐτόθεν καὶ οὐκ ἐκ στασίμου τινὸς καὶ ὅλου πνεύματος, ἀλλ' ᾗ ἂν τοῦτο τύχῃ, ῥυέν· οὐδὲ γὰρ ἂν ἦν ἀκέραια τὰ πλησίον· τῶν μὲν οὖν πνευμάτων καὶ αὕτη τις ἰδιότης.
