All the sines and logarithms in Wright’s translation of 1616 are shorter by one figure than those originally published by Napier in 1614. For example, in Napier’s table the sine of 0◦45_ is 130896 but appears as 13090 in Wright’s table. Wright also used a decimal point on some pages of his table, so that the logarithm of the sine of 89◦15_, listed in Napier’s table as 857, is 85.7 in Wright’s table. In this volume Wright’s translation has been kept unchanged, including typos, but Napier’s 1614 table is reproduced here instead of Wright’s.
