Catalogued as an important work outlining the applications of logarithms to trigonometry, it has also been described – for those more mathematically at ease than I, as “…a table of logarithmic sines and tangents for the hundredth part of every degree to 14 decimal places, a table of natural sines to 15 places and the tangents and secants for the same to 10 places”.
The work was completed by Henry Gellibrand for publication in Gouda, three years after Briggs’ death.
In rebacked and somewhat stained contemporary speckled calf with yapped edges, it showed some worming and spotting, but this is a rarely seen work.
