Διὰ τοῦτο καὶ τὰς ἐκ τούτων λαμβανομένας τῶν πυρετῶν διαφορὰς ἐπουσιώδεις εἶναί φαμεν καὶ οὐ κατ᾽οὐσίαν, κατ᾽οὐσίαν ὄυσης τῆς πρώτης διαφορᾶς ἢ διὰ τὸ μᾶλλὸν τε καὶ τὸ ἧττον τῆς παρὰ φύσιν θερμότητος λαμβάνεταί τε καὶ λέγεται, καθ’ ἣν μεγάλους καὶ μικρούς φαμεν πυρετούς, ὥσπερ εἴρηται· πάσας δὲ ταύτας τῶν πυρετῶν τὰς διαφορὰς τῶν πρὸ ἡμῶν τις ἀκριβῶς τε ἅμα καὶ σαφῶς ἐδήλωσε λέγων.
