As 10 to the power of 2 is equal to 100,there fore logarithm of 100 to the base 10 is equal 2.In the same analysis log 3 to the base 10 is 0.4771 as per log tables.Now how this figure of 0.4771 was discovered by Napier.Similarly,how the figures for log of other numbers were calculated/discovered by Napier.

I don't know, but you might want to check whether Taylor Series had been discovered in Napier's day.

Off the top of my head I would assume he used summations which are used for square roots, trigonometry functions (sine, cosine, etc.), etc. If your familiar with calculus this should be straight forward if you were to look up how to do it in a calculus textbook.
