The "beginning of modern astrometry". – (DSB)Erste Ausgabe. – Honeyman 311. Norman 226. DSB II, 102. Houzeau/Lancaster I, 10117: "L’auteur réduit un grand nombre d’observations de Bradley. En comparant ces observations à celles qu’il a faites à Königsberg, il détermine les coefficients des éléments de réduction, notamment de la précession, de la nutation, de l’aberration." – "This work also gives the proper motions of the stars, as derived from the observations of Bradley, of Piazzi, and of Bessel himself. It constitutes a milestone in the history of astronomical observations, for until then positions of stars could not be given with comparable accuracy: through Bessel’s work, Bradley’s observations were made to mark the beginning of modern astrometry" (DSB II, 99). – Titel mit getilgtem Stempel, hinterer Vorsatz wasserrandig, etw. fleckig, papierbedingt gebräunt.
