The private parts of a woman. Ham Carvel, a jealous old doctor, being in bed with his wife, dreamed that the Devil gave him a ring, which, so long as he had it on his finger, would prevent his being made a cuckold: waking he found he had got his finger the Lord knows where. See Rabelais, and Prior's versification of the story.
