Together with tables of the sun and stars right ascension and declination, of the latitude and longitude of places, of meridional parts. Likewise a traverse-table, a perpetual almanack; and other things very useful in the art of navigation. And the logarithm sines and tangents, with the logarithms of natural numbers, from 1 to 10000, according to those exact tables formerly set forth.
