(SCENE. - DR. STOCKMANN'S sitting-room. It is evening. The room is plainly but neatly appointed and furnished. In the right-hand wall are two doors; the farther leads out to the hall, the nearer to the doctor's study. In the left-hand wall, opposite the door leading to the hall, is a door leading to the other rooms occupied by the family. In the middle of the same wall stands the stove, and, further forward, a couch with a looking-glass hanging over it and an oval table in front of it.
