1930-1935

Milne-Shaw seismograph no.1, designed and constructed by John Johnson Shaw, 1914, based on an original design by John Milne. The instrument, which has a horizontal pendulum and electromagnetic damping, was tested at Bidston Observatory, near Liverpool, and in 1918 was transferred to the University Observatory at Oxford.
