Excerpt from Results of Meridian Observations, Made at the Royal Observatory, Cape of Good Hope, During the Years 1866 to 1870 Details of the Meridian work of the Cape Observatory from 1 8 34 to 1 870 were given in the Introduction to the Meridian Observations, 1861 to 1 86 5. The present volume contains the results of Meridian Observations, 1866 to 1 870, and completes the publication of all observations made with the transit-circle under the direction of Sir Thomas Maclear. The Transit Circle was constructed upon Sir George Airy's plans by Messrs Ransomes 8: Sims, as engineers, and Messrs Troughton Simms, as opticians. It is similar in construction and power to the transit-circle of the Royal Observatory, Greenwich. An elaborate description, with plans, of the Greenwich instrument is given. In the volumes of Greenwich Observations, 1852 and 1867; this renders any detailed description of the Cape instrument unnecessary. The only points of difference are that the setting-circle and the handles for moving the instrument are removed from connection with the graduated circle to the opposite side of the instrument, and that the central cube is pierced to allow adjustment of the collimating telescopes upon each other, without obstruction, and with out the necessity for raising the Transit Circle.
