Etiquette for the Ladies-in-Waiting by Miss Delaney Burney

1. If you find a cough tickling your throat, you must arrest it from making any sound. If you find yourself choking with forbearance, you must choke but not cough. 
2. In the second place, you must not sneeze. If you have a vehement cold, you must take no notice of it. If your nose membranes feel a great irritation, you must hold your breath. If a sneeze still insists upon making its way, you must oppose it by keeping your teeth grinding together, if the violence of the repulse breaks a blood vessel, you must break the blood vessel but not sneeze.
3. In the third place, you must not upon any account stir either hand or foot. If by chance a black pin runs into your head, you must not take it out. If the pain is very great you must be sure to bear it without wincing.
4.  If it brings tears to your eyes, you must not wipe them off, if they give a tingling by running down your cheek, you must act as if nothing was the matter. If the blood should gush by any means of the black pin, you must let it gush.
5.  If you are uneasy of making such a blurred appearance, you must be uneasy but say nothing about it. If, however, the agony is very great you may privately bite the inside of your cheek or of your lips for a little relief; taking care meanwhile to do it so cautiously as to make no apparent dent outwardly. And with the precaution, if you even gnaw a piece out, it will not be minded only to be sure either to swallow it or commit it to a corner of the inside of your mouth till they are gone for you must not spit.
