The situation the Lord Mayor holds is the first officer of the first city in the world in point of commerce and riches, and everything that can constitute the magnificence of a city. He is a judicial officer, and a municipal officer too, and from these combined characters there are duties incumbent upon him, which by all the ties that can bind a man to the discharge of duty, he is bound to discharge. It stands at the head of his duties, next after protecting the religion which binds us to God, to govern that civil policy which binds government together, and prevents us from being a state of anarchy and confusion.
