ἀντικειμένως δὲ τούτῳ διὰ τὴν αὐτὴν καὶ παρομοίαν αἰτίαν τὰ καιόμενα θᾶττον κατακαίεται χειμῶνος ἢ θέρους ἀσθενέστερον γὰρ ποιεῖ τὸ πῦρ τὸ θέρος ὥσπερ καὶ ὁ ἥλιος καὶ αὐτὸ τὸ πῦρ τὸ φῶς, ὁ δὲ χειμὼν καὶ τὸ τοῦ πέριξ ἀέρος ψυχρὸν ἀθροίζει, συνηθροισμένον δὲ πᾶν ἰσχυρόν· διὸ καὶ τὸ ἐν τοῖς λαμπτῆρσι φῶς ἐπὶ πλεῖον φαίνεται. ὅλως δὲ συνεστηκυῖα καὶ ἀθρόος ἡ δύναμις ἅπαντος ἰσχυροτέρα καθάπερ τοῦ βάρους· ὥσπερ γὰρ μεῖζον γίνεται.
