Book Description
Excerpt from The American Ephemeris and Nautical Almanac, for the Year 1863 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, its details, the values of the constants adopted, and the means employed in various parts of the work to secure additional accuracy, or greater convenience, will be found in the Preface and Appendix of the first volume, for the year 1855. The contents of the volume for this year are the same, generally. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from The American Ephemeris and Nautical Almanac for the Year 1881 In the present volume ten fundamental time-stars have been added to the list, to fill gaps; the right ascensions of the time-stars have been corrected from a new investigation; and the declinations of the whole list are from a paper by Mr. Lewis Boss, now in press. No other important change has been made. Extensive changes are however to be made in the volume for the year 1882, including a considerable extension of the star list for the use of field observers. An account of the data employed in the preparation will be found in the Appendix. A supplement contains tables for finding the latitude of a place by altitudes of the pole-star.

Not illustrated. 1859 edition. Excerpt: ...multiplied by 3, gives 2'58o for the variation in 3 hours, and this being added (because the equation is increasing) to o, m 59" 10, the equation of time at apparent noon, the result w iom 68, to be added (according to the precept at the head of the column) to the given apparent time 6h, whence we obtain 6h iom i' 68 for the mean time required. At page I. of the month of April, we observe, at the head of the column subt'f'onii W'c signifies that a change of precept occurs in the course of the month; and between the equations opposite to the 15th and 16th days of the month, a black line, indicating that the change occurs between the apparent noons of those days. The upper precept applies to all the quantities above the black line; and the lower precept to all the quantities below it: that is, in the instance referred to, the equation of time is to be added to apparent time from the 1st of April to the instant at which the equation becomes om o', which happens between the noons of the 15th and 16th days of the month; but after that instant the equation is to be subtracted from apparent to obtain mean time. Page II. of each Month. The Sun's Apparent Sight Ascension and Declination at mean noon have been deduced from its apparent Longitude and Latitude given at page III., and the apparent obliquity of the ecliptic at page 242. They denote the apparent position of the true Sun with reference to the equator, and the true equinox, at the instant the Greenwich mean time clock, or chronometer, indicates oh om o, or when the hour angle of the true Sun is equal to the equation of time. To find the Right Ascension and Declination for any other mean time and place, as at 9h 20m A.M. March 2, 1863, in longitude 980, or 61' 32%...
