18. πόλεων κόσμοι—συναγωγοί. The phraseology no less than the rhythm is highly poetical.
19. τίνα οὖν τρόπον. For οὖν retained in the indirect the editors cite Symp. 219D ὥστε οὔθ᾽ ὅπως οὖν ὀργιζοίμην εἶχον οὔθ᾽ ὅπῃ προσαγαγοίμην αὐτὸν ηὐπόρουν. Cobet's δῶ for δοίη is attractive but unnecessary.
20. πότερον ὡς κτλ. ‘Eleganter omissum ἔφη, ut obliqua oratio statim in rectam transeat’ Heindorf, quoting (inter alia) Xen. Cyrop. I. 4. 28 ἐνταῦθα δὴ τὸν Κῦρον γελάσαι τε ἐκ τῶν ρπόσθεν δακπύων καὶ εἰρεῖν αὐτῷ ἀριόντα θαππεῖν ὅτι ραπέσται αὖθις ὀλίγου χρόνου: ὥστε ὁρᾶν σοι ἐξέσται κἂν βούλῃ ἀσκαρδαμυκτεί. Sauppe quotes an exact parallel in 338Bbelow εἶπον οὖν ἐγὼ ὅτι αἰσχρὸν εἴη βραβευτὴν ἑλέσθαι τῶν λόγων. ειτε γὰρ χείρων ἔσται κτλ.
22. εις ἔχων ἰατρικὴν—ἰδιώταις. This division of labour takes place as soon as men begin to unite in cities: cf. Rep. II. 369Eff.
