Note 49 — Chapter VIII · PLATONIC COMPOSITIONS GENERALLY.

We may remark that Thrasyllus, though he enrols the Protagoras under the class Investigative, and the sub-class Agonistic, places it alone in a still lower class which he calls Ἐνδεικτικός. Now, if we turn to the Platonic dialogue Euthydêmus, p. 278 D, we shall see that Plato uses the words ἐνδείξομαι and ὑφηγήσομαι as exact equivalents: so that ἐνδεικτικὸς would have the same meaning as ὑφηγητικός.
