Lady Dalrymple was full of him.

She told all about his family, his income, his habits, and his mode of life.

She mentioned, with much satisfaction, that he had made inquiries after Minnie, and that she had promised to introduce him to her the next time he called.
Upon which he had laughingly insisted on calling the next day.

All of which led Lady Dalrymple to conclude that he had seen Minnie somewhere, and had fallen in love with her.
This was the pleasing strain of conversation into which the ladies were led off by Lady Dalrymple.

When I say the ladies, I mean Lady Dalrymple and Minnie.
