An untitled book of calculations and tables relating to Saturn, Jupiter, Jupiter's satellites and other planets, and to lunar and stellar places, 186 folios. There is a copy of a letter to John Caswell about a geometrical theorem (80v), tables of refractions (185r), and a conversion table for the scale of an instrument (inside the back cover). The writing is mostly in Flamsteed's hand, but other hands also appear, including that of Abraham Sharp. The volume was begun on 16 December 1689. The items date principally from before 1693, but there are notes up to 25 May 1698.
