The Ladies' Book of Etiquette, and Manual of Politeness

Do not press those near you to take more or other things than are upon their plate. This is the duty of the hostess, or, if the company is large, the servants will attend to it. For you to do so is officious and ill-bred. When conversing let your knife and fork rest easily upon your plate, even if still in your hand. Avoid holding them upright. Keep your own knife, fork, and spoon solely for the articles upon your own plate. To use them for helping yourself to butter or salt, is rude in the extreme. When you do not use the salt-spoon, sugar tongs, and butter-knife, you may be sure that those around you will conclude that you have never seen the articles, and do not know their use. You need not fear to offend by refusing to take wine with a gentleman, even your host. If you decline gracefully, he will appreciate the delicacy which makes you refuse. If, however, you have no conscientious scruples, and are invited to take wine, bow, and merely raise the glass to your lips, then set it down again. You may thus acknowledge the courtesy, and yet avoid actually drinking the wine. No lady should drink wine at dinner. Even if her head is strong enough to bear it, she will find her cheeks, soon after the indulgence, flushed, hot, and uncomfortable; and if the room is warm, and the dinner a long one, she will probably pay the penalty of her folly, by having a headache all the evening.
