Scope and Contents From the Series: The first part of collection is comprised of papers concerning the internal affairs of the Board of Longitude, including the granting of awards, accounts, minutes, committee papers, petitions and memorials, the loan of instruments, publications and the payment of staff. These are followed by a wide range of papers relating to the Board's work, concerning clocks, chronometers and other instruments; longitude and latitude; magnetic variation; schemes and inventions; tables; pendulum...

Scope and Contents

Reductions by H. Breen of observations made by James Bradley at the Royal Observatory during 1743-1750. The volume includes computations of precessions in right ascension and computations of the correction to the right ascension arc of Bessel's 36 stars.

Scope and Contents

Right ascensions of 36 principal stars in sidereal time deduced from James Bradley's observations (1750-1758) and corrected up to 1758. There is also a comparison with the 'Nautical Catalogue' of 1805, apparently to determine values for proper motion.

Scope and Contents

Various star catalogues compiled by Maskelyne from James Bradley's observations, and computations of the proper motions of some stars.

Scope and Contents

A Latin star catalogue giving the longitudes and latitudes of the principal stars, 1760; extracts of dates of James Bradley's observations with the mural quadrant; observations of the eclipses of Jupiter's satellites, 1750-1755; and a letter from J. Williams, Mile End, London, 11 November 1801, requesting clarification of some ambiguous elements, with a calculation on the ellipse on the reverse.

Scope and Contents Various observations of stars. The volume has been bound incorrectly and the articles are out of sequence. It is chiefly a work on the right ascensions of stars as derived from observations of the star Eta Aquilae.1. Mural quadrant observations of Arcturus made by James Bradley, 5 May 1743, with other references to that star.2. A table on the motion of stars, 1750-1790.3. Right ascension of Pegasus, 1765-1766.4. Mean right ascensions of stars to...

Scope and Contents Various observations and calculations, primarily of the stars.1. Tables and equations for the Earth's perturbations by Venus and Jupiter and for the lunar equation.2. Catalogue of the stars for 1690 and 1760, with elements for their aberrations.3. Corrections for the tables of Dalembert, Halley, Mayer and Clairaut.4. To find the aberration in right ascension and declination.5. Comparisons with Nicholas Louis de Lacaille's star catalogue, 1750 and...

Scope and Contents A collection of tables, some computed by Halley but in the handwriting of James Bradley.1. Table of observations for the right ascension of the Moon, 13 January 1722 - 4 December 1725.2. Tables of the observed longitude of the Moon, 5 December 1725 - 11 April 1745.3. Table of the observed longitude and latitude of the Moon, 7 June 1737 - 23 March 1747.4. Right ascension, zenith distance, longitude and latitude of the Moon observed at Greenwich, 13 September...

Scope and Contents

Notes on how to observe the satellites and use the tables are included, together with copied pieces on Ole Rømer, 'Progressive Motion of Light in the Eclipses of Jupiter's Satellites', from 'Philosophical Transactions', Vol. 1, p. 409; Edmond Halley's hypothesis of Jupiter's satellites and his counter-arguments, from 'Philosophical Transactions', No. 214, November and December 1694; and James Bradley, 'Observations of Jupiter's Satellites'.

Scope and Contents

An undated text on James Bradley's work on a physical theory of the nutation of the Earth's axis, with three diagrams to illustrate the theories.

Scope and Contents

Copy of king's warrants of priory seal issuing payments to Dr James Bradley (15 Feb. 1752) and to Nathaniel Bliss (11 Aug. 1762) for their roles as Astronomer Royal.

Scope and Contents

Miscellaneous works on stars and comets, including:

1. Some results for the constellation Hercules and a table of corrections to the observations.

2. Observations and discovery of the 1723 comet, with an account of its position and path through the heavens; written by James Bradley.

3. Calculations made in 1746 to ascertain the 1744 comet's latitude.
