Letters from various British and international observatories on filling vacancies, requests for new instruments at Sydney, and covering letters to reports. Approximately half the correspondence is concerned with the possible closures and alternative uses of the Madras, Bombay and Colaba observatories; reports on the Madras and Colaba observatories and their history; and governmental recommendations for the Indian observatories. The correspondents on these matters include E.B. Eastwick, J.F.W. Herschel, Lord Cranborne, N.R. Pogson, J. Baxendell, H. Merivale and S.H. Northcote. The letters include briefer correspondence with J.R. Hind, C. Abbe, R.L.J. Ellery, Earl Rosse, U.J.J. Le Verrier, E.J. Routh, O. Struve and Lord Wrottesley. There are also two star charts; a drawing of the latitudes of various observatories; reports on the Berlin Observatory by W.J. Foerster and on Kingston Observatory, Canada, with a drawing; French accounts of Greenwich and French astronomical observations; a photograph, possibly of Lund Observatory; and two photographs of Moscow Observatory.
