“Napier,” naˈpe-er, John. (1550-1617.) An English mathematician. “Logarithms” are numbers so related to natural numbers that the multiplication and division of the latter may be performed by addition and subtraction, and the raising to powers and the extraction of roots by the multiplication and division of the former. They are arranged in tables which can be readily understood and used, and they save enormous calculations and labor.
