The arts and sciences, in general, during the three or four last centuries, have had a regular course of progressive improvement. The inventions in mechanic arts, the discoveries in natural philosophy, navigation and commerce, and the advancement of civilization and humanity, have occasioned changes in the condition of the world and the human character which would have astonished the most refined nations of antiquity. A continuation of similar exertions is everyday rendering Europe more and more like one community, or single family.
