The first advance consisted in substituting for the old Boethian arithmetic, inherited from the Romans, the more powerful algorism of the Arabs, introduced by way of the trade routes between England and Italy. In the hands of the English, however, arithmetic was soon transformed into the practical art demanded by their commerce and characteristic of their genius, the most notable addition being the invention of logarithms. So rapidly was this transformation effected that within a decade after the invention of logarithms they had come into general use.

With the growing mastery of man over nature the effect of environment in modifying history becomes somewhat less apparent. Sufficient has been said, however, to suggest the dynamic influence of geography upon culture, and indicate the new light thrown upon intellectual development when studied from the standpoint of physiography.
