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...

Sun's declination, 2 May 1768 - 1 January 1769.2. Obliquity of the ecliptic, 1 August 1767 - 1 November 1769.3. Sun's declination from 1 August 1767 to 26 January 1769.4. Sun's longitude from computations of Johann Mayer's tables, 25 January 1768 - 12 May 1768. The computations are missing.5. Reductions of...

Scope and Contents

'Lunar theory in conjunction with the Newtonian system.' The work includes Johann Mayer's tables, preparation and reduction of the equations, workings in infinitesimal calculus, the solar parallaxes and the Moon's longitude.

Scope and Contents Part of the computations of Charles Mason's lunar tables of 1778, including comparisons of the tables of the Moon in longitude and latitude, with observations. The volume includes tables on the annual equation of the anomaly and ascending node of the Moon, details of the Moon's longitude, corrections and reductions. There are computations of the Moon's longitude and latitude as compared to Johann Mayer's tables, 1751-1760; computed longitude of the Moon compared with observed longitude,...
