For finding the Distance of Terrestrial Objects at Sea, in Statute miles.

Seek the nearest number to the reduced time in the top column, and the difference of parallax, proportional logarithm, or semi-diameter for 12 hours in the side column; under the former and opposite the latter, is the correction to be applied to the number, marked first in the Nautical Almanac, additive if increasing, subtractive if decreasing.
