TitleUnpublished manuscript, 'A method of deducing the longitude from the moon's right ascension' by Thos [Thomas] Kerigan
Date28 January 1832
DescriptionKerigan explains his method for finding the true meridian of the place of observation from the moon's right ascension. He provides examples of these calculations and states that when a chronometer with the mean time at Greenwich is also used, the longitude of any place can be determined.

The title was changed in ink from the original title, 'A new and correct method of finding the longitude'. John George Children's initials appear below the date received. Annotations and corrections appear throughout in ink and graphite. An ink inscription on the first page reads 'not to be printed'.

Subject: Geodesy / Astronomy

Written by Kerigan in Portsea [Porstmouth, England]. Communicated by Sir Edwd [Edward] Codrington. Received by the Royal Society from the President [Augustus Frederick] on 18 February 1832. Read 15 March 1832.

Whilst the Royal Society declined to publish this paper in full, an abstract of the paper was published in volume 3 of Abstracts of the Papers Printed in the Philosophical Transactions of the Royal Society of London [later Proceedings of the Royal Society] as 'A method of deducing the longitude from the moon’s right ascension'.
