| Title | Manuscript, 'Account of pendulum experiments undertaken in the Harton Colliery, for the purpose of determining the mean density of the earth' by G B [George Biddell] Airy |
| Date | [1855] |
| Description | An account of experiments conducted with a pendulum clock at Harton Colliery, a 1260 foot deep coal mine near South Shields in County Durham. The work was undertaken to determine the mean density of the earth by taking comparative measurements at the top and bottom of the mine and noting the influence of gravity on the timekeeping of each set of instruments. Airy and William Whewell conducted similar experiments at Dolcoath mine in Cornwall during the period 1826-1828.
