LADY BRACKNELL. It certainly has changed its colour. From what cause I, of course, cannot say. [Algernon crosses and hands tea.] Thank you. I’ve quite a treat for you to-night, Algernon. I am going to send you down with Mary Farquhar. She is such a nice woman, and so attentive to her husband. It’s delightful to watch them.
