Letter concerning the longitudes of the stars from Johann Mayer's and Charles Mason's tables, 1787-07-16
The letters are primarily from Nevil Maskelyne but include three sent to Andrews by Margaret Maskelyne, following the death of her father.
A letter from Charles Mason, Tetbury, Gloucestershire, giving details of errors for the solar tables.
Lunar computations for Charles Mason's new tables of 1772, covering the period 13 September 1750 to 31 December 1759. For each year there are remarks on the accuracy of the observations and computations.
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].
An undated photocopy of 'Maskelyne Book 2' entitled 'Presents of my Observations, Papers in the Philosophical Transactions, &c', covering 1775-1803. The book includes the names of people to whom Nevil Maskelyne has arranged to give speeches, including Joseph de Lalande, Sir John Pringle, Charles Mason, Dr Lind and Jean Delambre.

The Moon's longitude deduced from Charles Mason's tables of 1776, and compared with observed longitude, 8 January 1750 - 31 December 1759. There are also tables of the Moon and Sun's positions, 13 September 1750 - 2 November 1760, and abstracts of errors of Mason's lunar tables, 1750-1752.
The Moon's observed right ascension, declination, longitude and latitude compared with Johann Mayer's tables, 8 January 1772 - 30 December 1776, and with Charles Mason's tables, 1 January 1777 - 30 December 1782.
Calculations and arguments for computing the Moon's tabular place, 13 September 1750 - 31 December 1759, with many calculations apparently on lunar equations. There are also tables on the longitude equations of the Moon, 29 September 1759 - 2 November 1760, and the latitude equations of the Moon, 1 January - 2 November 1760, calculated by Charles Mason.
