This article is intended as a contribution to the geography of eighteenth-century science. It analyses three cases of field science: Linnaeus's global travelling enterprise, the Danish Arabia expedition, and the early attempts in Britiain and Scandinavia to establish a North Atlantic, if not an Arctic, science. It points to the emergence of what we may wish to call domestic exteriors. Countries such as Denmark, Sweden and Great Britian carved out their respective shares and pockets of foreign lands where they specialised and established a more or less continuing presence. Enlightenment field science travelled globally, connected small nations with major powers, and built networks and patterns of influence and power that extended into new territories. Some of these territories were themselves northern, regions to which the study of Enlightenment science has hitherto rarely connected.
