The mariner's compass rectified: : containing tables, shewing the true hour of the day, the sun being upon any point of the compass: with the true time of the rising and setting of the sun and the stars, and the points of the compass upon which they rise and set: with tables of amplitudes. Which tables of sun-dials, semi-diurnal-arches, and amplitudes are calculated from the Equator to 60 degrees of latitutde, either north or south. : With the description and use of those instruments most in use in the art of navigation. : Also a table of the latitudes and longitudes of places. / By Andrew Wakely, mathematician.
