Not illustrated. 1877 edition. Excerpt: ...that is, with the planet's apparent altitude in either side column, and the horizontal parallax at the top, and is always additive to the auxiliary angle taken from Table XXX. Example. Required the correction of the auxiliary angle corresponding to the apparent altitude of a planet 65 and horizontal parallax 19'. Opposite the apparent altitude 65, and under the horizontal parallax 19', is the corresponding correction 10. TABLE LI. To reduce the Equation of Time to any Time at Greenwich. This table is to be entered with the daily change or variation of the equation of time (being the difference of the equations at the preceding and following noons, taken from Page I. or II. of the month in the Nautical Almanac, when they are both additive, or both subtractive, but their sum when one is subtractive, and the other additive, ) at the top, and the Greenwich time in the left side column; the corresponding correction is then to be applied to the equation at the preceding noon, by addition or subtraction, according as the equation is increasing or decreasing. But should the correction exceed the equation at the preceding noon, the latter is to be subtracted from the correction, and the remainder will be the reduced equation, to be applied in the same way us directed in the Nautical Almanac for the equation at the following noon. When the Greenwich time exceeds 12 hours, the correction must be taken out at twice, as in the third and fourth Examples. Example I. Required the equation of time, March let, 1874, at 3 hour6 XXmil.
