This series comprises four folders of letters sent by Lady Clive to her brother Nevil Maskelyne, her niece Margaret Maskelyne, and to other family members.

The series also includes a set of copies of family letters (including some written by Nevil Maskelyne), and notes by Theresa Story-Maskelyne on the letters of Lady Clive.
The letters are primarily from Nevil Maskelyne but include three sent to Andrews by Margaret Maskelyne, following the death of her father.
Various rough drafts of the solution of astronomical problems.
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.
It is not known if the papers are foliated in their original order.
