Excerpt from The Complete Mathematical and General Navigation Tables, Including Every Table Required With the Nautical Almanac in Finding the Latitude and Longitude, Vol. 1 of 2: With an Explanation of Their Construction, Use, and Application to Navigation and Nautical Astronomy, Trigonometry, Dialling, Gunnery, Etc. Etc Table XIX. Is fully adapted to the reduction of the true altitudes of the heavenly bodies, obtained by calculation, to their apparent central altitudes: the reductions of altitude may be very readily taken out to the decimal part of a second. This table will be found of considerable utility in deducing the longitude from the lunar observations, when the distance only has been observed. Table XX. Is new; and by its means the operation of reducing the apparent central distance between the moon and sun, a fixed star, or planet, to the true central distance, is very much abridged, as will appear evident by referring to Method I., vol. I., page 481, where the true central distance is found by the simple addition of five natural versed sines.
