The Ladies' Book of Etiquette, and Manual of Politeness

Avoid handling the play bills, as the printing ink will soil your gloves in a few minutes, making your hands appear very badly for the rest of the evening. You should be in your seat at the opera before the overture commences. Never converse during the performance. Even the lowest toned remark will disturb a real lover of music, and these will be near you on all sides. Exclamations of admiration, "Exquisite!" "Beautiful!" or "Lovely!" are in the worst taste. Show your appreciation by quiet attention to every note, and avoid every exclamation or gesture. In our new opera houses there are rooms for promenade, and between the acts your escort may invite you to walk there. You may accept the invitation with perfect propriety. He will leave the box first and then offer his hand to you. In the lobby take his arm, and keep it until you return to the box. If you have taken your cloak or shawl to your seat, leave them there during your promenade. Return to your seat when the gong sounds the recall, that you may not disturb others after the next act commences. In walking up and down in the promenading saloon, you may pass and repass friends. Bow the first time you meet them, but not again. If you meet your gentlemen friends there, bow, but do not stop to speak. They may join you for once round the room, then allow them to leave you. Your escort will feel justly offended if you allow any other gentlemen to engross your attention entirely when he has invited you to the entertainment.
