When the King rises from his noonday sleep, the woman whose duty it is to inform the King regarding the wife who is to spend the night with him should come to him accompanied by the female attendants of that wife whose turn may have arrived in the regular course, and of her who may have been accidentally passed over as her turn arrived, and of her who may have been unwell at the time of her turn. These attendants should place before the King the ointments and unguents sent by each of these wives, marked with the seal of her ring, and their names and their reasons for sending the ointments should be told to the King. After this the King accepts the ointment of one of them, who then is informed that her ointment has been accepted, and that her day has been settled.
