How is a mercury barometer construct?

A mercury barometer consists of a tall glass tube filled with mercury inverted into a container of mercury. The mercury in the tube will fall until the weight of the mercury column is balanced by the atmospheric pressure pushing down on the surface of the mercury in the container. The measurement is then taken from the height of the mercury column in the tube.
