Description
Plan and elevation of the masonry pillar for a transit instrument and a diagram for a wooden plank to be fixed to the clock case used in John Goldingham’s temporary expedition observatory.
Figure nos.5-6 from Report of the length of the pendulum at the equator...made on an expedition...from the observatory at Madras..., by John Goldingham (Madras, 1824). Scale 1 inch: 2 feet and ¾ inch: 1 foot.
Original painting pasted onto a backing sheet. Not signed. Both papers watermarked: ‘C.Wilmot 1817’ and ‘J.Whatman 1817’.
This expedition to make gravity measurements by pendulum was led by John Goldingham of the Madras Observatory: “In order to compare and combine the Observations for the Length of the Pendulum taken in different Latitudes...it would be most desirable to have accurate Observations taken at the Equator...a part of the Island of Sumatra, which is under the influence of the Honorable [East India] Company’s Government, is crossed by the Equator, and offers a most eligible Station...”
John Goldingham (c.1766-1849) British astronomer was elected a Fellow of the Royal Society in 1808.
