Excerpt from The American Ephemeris and Nautical Almanac, for the Year 1869 The preparation of the American Ephemeris and Nautical Almanac was begun in the latter part of the year 1849, in accordance with an act of Congress, approved on the 3d of March of that year. An account of this preparation and the values of the constants adopted will be found in the Preface and Appendix of the first volume, for the year 1855. In the volume for 1865 the Star Ephemeris was greatly enlarged; new places of the Stars adopted; the form for Moon Culminations and moon-culminating Stars changed so that less space was required; Mean Solar Time, instead of Sidereal Time, used in the dates of the Ephemeris for the Meridian Of Washington; bessel's notation in the formulae for star-reductions substituted for baily's; and several other changes of less importance were made.
