This new survey of scientific endeavor within the British Empire is the most wide-ranging yet published, examining the interconnections between science, the British Empire, and the emergence of a globalized world. It identifies and analyzes the web of scientific networks crisscrossing the British Empire through which scientific knowledge and authority were produced, circulated and legitimated, critically engaging with new ways of thinking about networked connections across space. It offers a comparative perspective that surveys a variety of scientific initiatives and circuits, including networks of agronomists, anatomists, botanists, foresters, geologists, marine biologists, oceanographers and physicists. As they chart the evolving practices, strategies, theoretical ideas and agendas among research scientists, technical advisers, imperial administrators, and native peoples in Africa, Australia, Britain, India and elsewhere; each chapter combines rigorous research with theoretical reflection based on the latest literature, as well as serving as a useful introduction to that literature.
