ὡς ἐκ τῶν ὑ.—as well as he could, with ἐθάρσυνε.
βοῇ τε χ κ.τ.λ—raising his voice louder and louder still as he went from one line to another. So the note in Jowett, taking ἔτι μᾶλλον with ἑκάστοις, which is much better than understanding a reference back to the previous speech c. 69.2, as there is not much point in saying that he spoke even louder than he had spoken two days before.
γίγνοιτο—why optative?
γεγωνίσκων—a poetical word for γέγωνα.
