A close reading of the 1948 American-Australian Scientific Expedition to Arnhem Land, in northern Australia, is contextualized by a set of broader observations concerning the history of expeditions and their significance to science, anthropology, and geographical exploration. The essay addresses the role of expeditions in distributing trade goods, paying special attention to the distribution of tobacco and its implications. The supply of drugs such as tobacco provides insight into the bio-chemical engagement with the human body that underlay the project of bringing science to an inhabited terrain.This work was supported by Australian Research Council [grant numbers DP1096897 and FT0992291].application/pdfen-AU© 2019 Martin (Edward) Thomas201910.1080/02757206.2019.16952012022-04-10
