1. Τῶν δ᾿ ἐπὶ χυμοῖς σηπομένοις ἀναπτομένων πυρετῶν οἱ πρῶτοι μὲν εἴρηνται σκοποὶ πρόσθεν ἡνίκα ἐδείκνυον ὅπως ἐγχωρεῖ καὶ δύο καὶ τρεῖς αὐτοὺς ποιῆσαι, κἂν εἰ βουληθείημεν ἕνα. νυνὶ δ᾿ ὥσπερ ἐπὶ τῶν ἄλλων πυρετῶν ἐκ τῆς τῶν πρώτων γενῶν τομῆς ἄχρι τῶν ἐσχάτων εἰδῶν ἀφικόμεθα τέμνοντες, οὕτω πρᾶξαι πειραθῶμεν κἀπὶ τῆς προκειμένης διαφορᾶς, ἐκεῖνο πρότερον ἀναμνήσαντες ὃ κἀν τοῖς περὶ διαφορᾶς τῶν σφυγμῶν ὑπομνήμασιν ἐδείξαμεν, ὡς εἴτε πρώτας διαφοράς, εἴτε γένη πρῶτα καλεῖν ἐθέλοι τις, | 735Kεἴτε γενικωτάτας ἰδέας, εἴθ᾿ ὁπωσοῦν ἄλλως φυλάττων ἀκριβῆ τοῦ πράγματος τὴν ἔννοιαν, οὐ διοίσει. τῶν μὲν δὴ πυρετῶν αὐτῶν τοὺς ἐφημέρους ὅπως χρὴ θεραπεύειν ἐν τῷ τῶνδε τῶν ὑπομνημάτων ὀγδόῳ διῆλθον· ὥσπερ γε καὶ ὅπως τοὺς συνόχους ἐν τῷ μετ᾿ αὐτό· καὶ τρίτους γε τοὺς ἑκτικοὺς ἐν τῷ μετ᾿ ἐκεῖνο τῆς ὅλης πραγματείας ὄντι δεκάτῳ, μετὰ τῶν ἰδίων ἑκάστῳ πλεῖστα καὶ τῶν κοινῶν ἐπελθών. νυνὶ δ᾿ ὅπως ἄν τις ἰῷτο μεθόδῳ τοὺς ἐπὶ σήψει χυμῶν συνισταμένους πρόκειται διελθεῖν.
1. The primary indicators of the fevers kindled by putrefying734K humors have been stated before when I showed how it is possible to make them two or three, or even one, if we wish. Now, when I make divisions as in the case of the other fevers, I proceed from the division of the primary classes as far as the ultimate kinds. So let me attempt to do this in the case of the differentiae before us, first calling to mind what I demonstrated in the treatise On the Differentiae of the Pulses:1 that whether someone might wish to call them primary differentiae, or primary classes, or the most735K generic kinds, or name them in whatever other way, it will make no difference as long as he accurately preserves the concept of the matter. I went through in detail how we should treat the ephemeral fevers in the eighth book of the present treatise, just as I did with the continuous fevers in the book after that, and the hectic fevers in the one after that, which was the tenth of the whole work, when I covered the majority of those things specific to each of them and those that are common [to them all]. I now propose to go through in detail how someone might cure by method the continuous fevers which arise due to putrefaction of humors.
