The construction of the wonderful canon of logarithms

Remarks on Appendix. 63
the last quotient disturbs the ratio a little; but if we
assume the Logarithm of 10 to be 10,000,000,000,
and if 2 be multiplied by itself continuously until
the number of products is exceeded, by one only,
by the given Logarithm ; then the number of
places, less one, in the last product, will give the
Logarithm of 2 with sufficient accuracy, because
in large numbers the small fraction adhering to the
last quotient will have no effect in disturbing the
proportion.
THE
END.
