Hardback, [PU: Forgotten Books], Excerpt from The American Ephemeris and Nautical Almanac, 1870 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; bessnl's notation in the formulae for star-reductions substituted for baily's. Several other changes of less importance were made. In the volume for 1869 some slight changes were made in the epheme rides of Venus and Mars, and in the arrangement of the stars; and the explanations of the arrangement and use of the tables were revised so as to adapt them to the wants of operators at sea or in the field.
