Scope and Contents A compilation of lunar observations, with star catalogues, mainly in Flamsteed's hand, 184 folios. The volume includes 'Lunae Observationes Britannicae Regiae' ('Lunar Observations of the British Realm') made between May 1675 and September 1689, with data from various sources and analytical notes (3r-94r); 'Claudii Ptolemei ... Fixarum Catalogus' (Ptolemy's catalogue of the fixed stars), translated into Latin and compared with other catalogues by Flamsteed, 1702 (105r-128r); calculations...

Scope and Contents

Copies of two catalogues:

1. Messier's catalogue of nebulae arranged in order of right ascension for 1840, with constants for reducing the apparent places. A note by Tupman records that he has been unable to discover anything relating to the history of the catalogue, and that is was purchased in Berlin in 1867.

2. Translation of Ptolemy's catalogue by M. Halma, dated by Tupman 1867.

Scope and Contents Lunar and some planetary calculations, 24 November 1705 - 5 July 1706, with a few notes up to June 1709, 374 folios. There are eight sections, marked volumes 9 to 16, now bound together, with a few inserted loose leaves. The writing is mostly in John Witty's hand, but Flamsteed's also features.9. Lunar places (1680-1681) and related calculations, including extracts on eclipses from Ptolemy and Albategnius (17v-28v, 41v).10. Lunar right ascensions and north polar...

Scope and Contents A copy of Porter's script for 'The Night Sky in August' on statistical methods in astronomy; the Plough and the movement of Arcturus over 1,800 years since the time of Ptolemy, which Edmond Halley called attention to in 1718; the proper motions of stars, including Arcturus, Sirius and Procyon, analysed statistically by William Herschel, giving similar results to modern measurements; stellar velocities determined by spectroscopic analysis, the velocities increasing towards the galactic...

Scope and Contents An annotated copy of Porter's script for 'The Night Sky in January' on Venus (now the morning star), Saturn visible at dawn, Jupiter (the most visible planet in the evening sky), Mars below the Square of Pegasus, Mercury becoming visible, and Jupiter near Castor and Pollux in Gemini; Orion and Sirius, Uranus near Jupiter, and the Moon full when near Jupiter; the variable brightness of Mars; errors in the prediction of the brightness of Uranus; the brightness of stars and correlation of size,...

Scope and Contents An annotated copy of Porter's script for 'The Night Sky in May' on the Plough overhead, Arcturus in the south, Leo in the west, and Jupiter below Arcturus near Spica in Virgo; the retrograde motion of the planets, the difficulty in observing this motion and the lack of perspective in the sky; the misleading impression of distance given if apparent brightness is relied on, the proper motion of stars, and the importance of their distribution in this galaxy and their movements; the difficulties...

Scope and Contents Two copies of Porter's script for 'The Night Sky in September' on Mercury, Venus and Mars as morning stars and Jupiter; Vega, the Southern stars, Cygnus, Altair and Aquila, Vulpecula and Saturn, Sagitta, Equuleus and Delphinus; the Revd T.W. Webb's solution to the mystery of the names Svalocin and Rotanev for Alpha and Beta Delphinus; the Milky Way, the proper motions of stars and the movement of Sirius, Aldabaran, Betelgeuse and Arcturus listed in Ptolemy's catalogue and noted by Halley;...

('Claudius Ptolemy's regular disposition of constellations or catalogue of fixed stars, translated from Greek into Latin, amended ... by comparison with an Oxford manuscript and with the versions of Trapezuntius, Gauricus, Copernicus and Clavius, and also with the catalogue of Ulug Beigh, of Tycho Brahe, and the heavens themselves. The work of John Flamsteed, M. R. With the additional Greek and Roman...

Scope and Contents Theories of the Sun, Moon and planets, including a circular from M. Montagne on solar parallax; notes on Montucla, Pliny, Ptolemy and Halley relating to the saros of solar eclipses; tables by S. Newcomb on the transformation of P.A.
