§2.84.1ἡ δὲ ἰητρικὴ κατὰ τάδε σφι δέδασται· μιῆς νούσου ἕκαστος ἰητρός ἐστι καὶ οὐ πλεόνων.
On the other hand, medicine is distributed among them as follows: each physician is a physician of one disease and not of more.
πάντα δʼ ἰητρῶν ἐστι πλέα· οἳ μὲν γὰρ ὀφθαλμῶν ἰητροὶ κατεστᾶσι, οἳ δὲ κεφαλῆς, οἳ δὲ ὀδόντων, οἳ δὲ τῶν κατὰ νηδύν, οἳ δὲ τῶν ἀφανέων νούσων.
And all places are full of physicians; for some are established as physicians of the eyes, others of the head, others of the teeth, others of the things of the belly, and others of obscure diseases.
