I haven't mentioned even a fraction of the sins standing to their account: P. οὐδὲ πολλοστὸν μέρος εἴρηκα τῶν τούτοις ὑπαρχόντων κακῶν (Lys. 144).
you will live to wish that you might see even a fraction of it (our force sent to help you): P. ἔτι βουλήσεσθε καὶ πολλοστὸν μόριον αὐτῆς (τῆς ἐπικουρίας) ἰδεῖν (Thuc. 6, 86).
