'Fixarum Culminationes et Meridiane a vertice distantiae (cum declinationibus inde deductis) e protocollo Observationum primum in libellum minorem collectae deinceps in hunc transcriptae' ('The culminations and meridional zenith distances of the fixed stars (with declinations deduced from thence) first collected from observing-notes into a smaller book and then transcribed into this'): data from observations of 1689 onwards, copied mainly in 1691, 1703 and later, 91 folios. There are later additions, running up to 1711, which also include instructions for constructing sundials (78v-80r) and correspondence with John Caswell, 1709 (63r, 64r). The writing is mainly in Flamsteed's hand. Francis Baily identified the volume as Flamsteed's 'liber niger' ('the black book').
