Anonymous, Beadle's Dime Book of Practical Etiquette for Ladies and Gentlemen
“ Before passing into the dining-room, each gentleman offers his left arm to a lady, and conducts her to table.Beware of arriving too early or too late: in either case there is an awkwardness—in the former you inconvenience your host; in the latter, his guests.Once at table, you should not lose sight of the plate or glass of your fair neighbor, showing yourself attentive, without affectation or over-officiousness.Meat should be cut only according as it is carried to the mouth. To cut up a plateful is the very height of greediness and ill-breeding. ”
