She was hasty, but good-humoured; vain (she could not help it, when every glance in the glass showed her such a flush of loveliness), but not affected; liberal-handed; innocent of the pride of wealth; ingenuous; sufficiently intelligent; gay, lively, and unthinking: she was very charming, in short, even to a cool observer of her own sex like me; but she was not profoundly interesting or thoroughly impressive.
There are no more uses of "ingenuous" in the book.
