Lunar tables, 1778
Lunar tables in longitude and latitude according to the Newtonian law of gravity, by Charles Mason, 1778. The volume includes a disapproval of Mason's fee from the Board of Longitude [RGO 4/86: 2]; an example of computing the Moon's longitude and latitude; annual equations of the Moon's anomaly and ascending node; and computed longitude and latitude compared with observed longitude and latitude, with corrections, 13 September 1750 - 2 November 1760 [RGO 4/86: 14r].

Miscellaneous correspondence, 1783 - 1828
Miscellaneous correspondence relating mainly to methods of finding longitude at sea.
Nautical astronomy, 1770 - 1810
A set of loose pages dealing with problems in ascertaining latitude and longitude at sea by observation of the stars, with descriptions, computations and formulae referred to apparent time. There are also sections on finding the Moon's longitude from the nautical ephemeris [RGO 4/196: 1r], the motion of the Sun's image in a Hadley quadrant [RGO 4/196: 2r], and the testing of other people's hypotheses.
