SOME REMARKS

BY THE LEARNED

HENRY BRIGGS

On the foregoing Appendix.

The relations of Logarithms and their natural
numbers to each other, when the Logarithm
of unity ts made 0.

T[A]Wo numbers with their Logarithms being given; of both Logarithms be divided by some common divisor, and if each of the given numbers be multiplied by itself continuously, until the number of multiplications ts exceeded, by unity only, by the quotient of the Logarithm of the other number, two equal numbers will be produced. And the Logarithm of the number produced will be the continued product of the quotients of the Logarithms and their common divisor.

Logarithms.
Let the given numbers be
