Vertical Pendulum Tilt Meter
"As a result of the successful tests with the Claustral Pendulum, Bidston acquired a Graf-Askania vertical pendulum of its own, and installed it after modification." [1]
"In 1900 Biddston obtained its own Milne-Seismograph. and tables of its observations were published from 1901." [2]
The Dock Board felt that "meteorological observations could be taken with equal accuracy elsewhere" and the Dock Board's "interest in th unfelt tremors of the earth was not immediate".[3]

Reading and changing the seismographic records was part of the daily routine in Bidston Observatory.[5]
"However, a new activity commenced in 1897 with the installation in the cellars of a seismograph. This was the first of a series of seismographs of different designs that followed. In 1910, observations were made using instruments designed by Sir George Darwin, Sir Horace Darwin and others to determine the yielding of the land to the load of tidal water, now called the ‘ocean loading effect’."[6]
