The Book of Household Management by Mrs. Beeton

35. DINNER BEING ANNOUNCED, the host offers his arm to, and places on

his right hand at the dinner-table, the lady to whom he desires to pay most respect, either on account of her age, position, or from her being the greatest stranger in the party. If this lady be married and her husband present, the latter takes the hostess to her place at table, and seats himself at her right hand. The rest of the company follow in couples, as specified by the master and mistress of the house, arranging the party according to their rank and other circumstances which may be known to the host and hostess. It will be found of great assistance to the placing of a party at the dinner-table, to have the names of the guests neatly (and correctly) written on small cards, and placed at that part of the table where it is desired they should sit. With respect to the number of guests, it has often been said, that a private dinner-party should consist of not less than the number of the Graces, or more than that of the Muses. A party of ten or twelve is, perhaps, in a general way, sufficient to enjoy themselves and be enjoyed. White kid gloves are worn by ladies at dinner-parties, but should be taken off before the business of dining commences.
