The first part of the volume deals with the minor planets, beginning with the Paris observations of asteroids between 1866 and 1872, chiefly in the form of correspondence with M. Loewy. There then follows pieces on the discovery of new planets by J.C. Watson, R. Luther and C.H.F. Peters, with their respective elements and ephemerides, and observations of known asteroids, with printed German ephemerides by T.E.V. Oppolzer of the small planets. The second part of the volume is devoted to comets, including Encke's, Brorsen's, Winnecke's, Tempel's and Tuttles', and a comet of 1683 with a 191 year periodic orbit. There are elements and ephemerides of these observations, with a printed German ephemeris by T.E.V. Oppolzer of Winnecke's Comet. There are also predicted paths for Halley's and Olbers' Comet and an article from 'Scientific Opinion' on comets and meteors.
