This work is probably the same as that mentioned in the beginning of chap. 5. (See chap. 5, note 1.) The work seems to have borne two titles ἡ πρεσβεία and περὶ ἀρετῶν. See Schürer, ibid. p. 859, who considers the δευτέρω here the addition of a copyist, who could not reconcile the two different titles given by Eusebius.
