The volume consists of Bernard de Fontenelle, ‘The life of Sir Isaac Newton’ (folio 3); John Lawson, ‘A synopsis of all the data for the construction of triangles’ (folio 17); and John Landen, ‘Observations on converging series’ (folio 29).

The remaining material is in manuscript: 'An investigation of the theorem on which the foregoing operations [i.e. Landen's article] are grounded' (folio 45); 'Geometrical analysis' a general criticism of the work of Thomas Simpson (folio 63); and 'Extracts from [Jacques] Ozanam's Dictionnaire Mathématique' of 1691 (folio 100). These items are all apparently in Thomas White's hand, and the first two may be by him. The last item in the volume is “An abstract of M. [Jean Etienne] Montucla's Histoire des Mathématiques” of 1758.
