   Customers wishing to purchase ale or beer, made the announcement by vibrating the ring up and down, or tirling at the door. The notification in question may be roughly represented by types in the annexed manner. I am not aware of any door-notificators of this description being now in existence in Glasgow. The last one that I saw was at the door of Mrs. Hunter, who kept the celebrated ale and beer house in the Trongate, in the through-gaun close opposite the Tontine Inn.
