The Post Office clock is undoubtedly the standard clock of Melbonrne. It is provided with a splendid mercurial compensating pendulum 15ft feet long, and keeps excellent time. Every day after 1 o’clock an electric switch is burned in the central Telegraph Office, and the beats of the Post Office clock are registered on the observatory chronograph. Its error thus becomes known every day to the fraction of a second, i nd is published in the daily papers. Unless, as sometimes happens with all mechanism, an accident occurs to the machinery, this clock is seldom more than lOaec wrong. The range of its error since the beginning of this ye «r has only been from Bsec slow to 9sec fast. This shows it to be fully equal in its performance to Big Ben at Westminster.
