This important work formed the basis of Vega's Thesaurus {q. v. ante), where it is termed 'opus rarissimum', and

 quadrant, also Briggs's tables of the first 20,000 logarithms carried to ten places of figures, besides a description of the 

 tables and their applications, chiefly extracted from Briggs's Trigonometria Britannica, which was published in the same 

 year by the same publishers.
