Papers relating to the Royal Astronomical Society. There are papers by Airy on the eyepiece for correcting atmospheric dispersion; the lunar eclipse of 12 July 1870; the transmission of foreign post parcels; a special point in the determination of the elements of the Moon's orbit from meridional observations of the Moon; the proposed devotion of an observatory to observations of the phenomena of Jupiter's satellites; the rejection in the lunar theory of the term of longitude depending for argument on eight times the mean longitude of Venus minus thirteen times the mean longitude of the Earth, introduced by Professor P.A. Hansen, and the effect of that rejection upon the state of the lunar tables and upon the lunar calculations which serve as a basis for ancient chronology; and a proposed new method of treating the lunar theory. There is also a newspaper cutting on 'Solar Frictions'; a book by C.A. Freeman; correspondence and a newspaper article on state assistance for the physics branch of astronomy; and general correspondence regarding the Royal Astronomical Society.
