Rough notes on mathematical, optical and astronomical problems, largely in the period 1777-1783, including a table of errors for an eye-glass. There are a number of poems and epigrams penned by Maskelyne whilst at Cambridge during 1750-1757, written in English and Latin, with versions of the 18th, 23rd, 29th and 84th Psalms and a translation of Sophocles. There is also a bill for food from H. Storey, 1810, and an etching. Some pages of manuscript have been cut from the volume.

Loose papers concerned with poetry and mathematical problems. The poetry is comprised principally of notes on the Eumenides and classical Greek poets. There is a review of the Oedipus of Sophocles, a reference to the rules of Aristotle, fluxions, a map of Palestine, a synopsis of writing technique and style, and equations involving parabolas.

Undated loose papers on the poems on the Eumenides, including an etching depicting a classical war, possibly Achilles and Hector under the walls of Troy.
