The study of the history of science is widely understood to be undergoing a profound and much-needed transformation, from a subject focused on Europe to one encompassing the entire world. Yet the aims of the field have always been global. During the decades after the Second World War the inevitable progress of Western science was seen as the key to its role in world history. From the 1970s the rise of cultural history and laboratory ethnographies undermined this assumption. Indebted to colonial anthropology, these approaches revealed that the power of science was not inherent, but the result of local and contingent processes. Explanation needed to be symmetrical in analysing practices of all kinds wherever they were found, from economics and divination in West Africa to supernatural healing and particle physics in the American heartland. The geographical and conceptual broadening of the field is thus a long-delayed outcome of developments extending back many decades. It also means that references to the ‘global’ in history of science – even more than elsewhere in the humanities – continue to resonate with the universalizing aims of the natural and social sciences.

This essay examines the working relationship between Charles Darwin and the Edinburgh gardener John Scott that developed in the wake of the publishing of the Origin of Species (1859). As the essay shows, Darwin sought to utilize Scott’s horticultural knowledge and experimental expertise in order to provide some of the specialized botanical evidence that the Origin was not intended to provide. Scott, meanwhile, sought to use Darwin’s patronage and tutelage in order to overcome his modest status as a gardener while making contributions to scientific knowledge. And for an intense two-year period (1862–4), Darwin and Scott’s relationship was productive and mutually beneficial: not only did Scott’s work supplement Darwin’s ongoing botanical research on sexual development and fertility, but also his Primula experiments appeared to provide ‘physiological’ evidence of speciation via selective breeding. What the essay argues, however, is that there were limits to what Scott was able to achieve due in part to his social standing and perceived character that ultimately cast a shadow over his findings.

This article examines the scientific legacy of the first Glasgow Botanic Gardens and the part they played in the global circulation of botanical knowledge, from their creation in 1817 to their relocation to the West End of Glasgow in 1841. Located in a thriving industrial city with strong commercial ties to the British Caribbean, the gardens stood at an important crossroads of political and economic interests, scientific discovery, cultural innovation and imperial motives. They were managed by the talented English botanist William Jackson Hooker, who strove to transform them into a training ground for prospective botanists and a leading scientific institution. Yet, like many other botanical establishments of similar stature at the time, the gardens encountered many financial setbacks that hampered their success and threatened the scientific ambitions of Hooker and his peers. This article discusses the extent of the gardens’ scientific contribution within and beyond the borders of Britain and seeks to determine the degree to which science in these gardens was constrained by economic factors.

Sir Albert Howard helped popularize the idea of translating ‘Eastern’ practice into ‘Western’ science in the field of agriculture. His approach to composting has been foundational to organic farming and counterposed with the field of agricultural chemistry. This depiction of feuding ideologies – organic versus chemical – is based largely on Howard’s opposition to the fragmentation of scientific knowledge and its products, especially artificial fertilizer. One underexplored aspect of Howard’s contest with the agricultural research establishment is the role played by intellectual property. This article contributes to Howard’s historiography by examining three topics related to his life’s work that concern money and patents: (1) the financial support for the Institute of Plant Industry at Indore, (2) an artificial manure patented by employees at Rothamsted Experimental Station and (3) a rival method in British municipal composting. I argue that Howard’s ideological difference with agricultural chemists was not reducible to generating soil fertility with compost. Rather, the feud consisted of a larger debate about innovation, ownership and the societal benefits of scientific research.

The burgeoning nineteenth-century public-museum sector built a significant part of its natural-history specimen collections through extensive international trading. The early 2020s has seen an upsurge of scholarly interest in this largely overlooked trade. Exchange was a distinctive aspect of the natural-history trade that reveals much about the diverse practices and motives of the institutional collectors. Economic-geographic benefits included conserving the limited financial resources of museums and exploiting complementarities in the geographic distribution of specimens. Collection management, institutional reputation, social connection and international diplomacy were also part of a complex mix of value making that shaped this important international trade. We analyse the exchange practices of the three largest museums in the Australian colonies in the final three decades of the nineteenth century who exchanged Australia’s ‘rare and curious’ fauna with collectors across the globe. By deploying and analysing extensive, comparative data on a particular form of natural history, zoology, and a particular kind of trade, exchange trading, among three Australian museums, this paper extends and enriches recent scholarship on the mobility of natural-history specimens and how they were traded.

How water is perceived and represented has an impact on the relationships between a given society and its water infrastructure. Historians have identified a shift in the perception of water during the nineteenth century, which was connected to the development of chemistry. From an understanding based in Hippocratic medicine and natural history that treated it as an infinite variety of substances, water eventually became understood as a simple compound consisting of oxygen and hydrogen. This resulted in the abstraction of water from its social and environmental contexts, with consequences for the way water was managed. This article aims to demonstrate that such a view gives a mistaken intellectual coherence to a fragmented and conflicted process, which involved continuities, an adaptation of old frameworks to new social priorities, and fine changes in scientific thinking and practices. This paper examines the scientific and political debates concerning water infrastructure, surveys and analyses on water quality, medical reports and political measures in nineteenth-century Italy. Ultimately, the reduction of ‘waters’ to ‘water’ in Italy was more about determining who had the authority to assess water quality in the process of creating and stabilizing new power relations between the public and the private spheres than about the abstraction of water from its social and environmental contexts.

In 1820 two French scientists – Pierre Joseph Pelletier and Jean Bienaimé Caventou – discovered and named the active alkaloid substance extracted from cinchona bark: quinine. The bark from the ‘wondrous’ fever tree, and its antimalarial properties, however, had long been known to both colonial scientists and indigenous Peruvians. From the mid-seventeenth century, cinchona bark, taken from trees that grow on the eastern slopes of the Andes, was part of a global circulation of botanical knowledge, practice and profit. By the 1850s, Europeans eager to bypass South American trade routes to access cinchona plants established plantations across the global South in French Algeria, Dutch Java and British India. Wardian cases – plant terrariums named after British physician Nathaniel Bagshaw Ward – would fuel new imperial efforts to curb malaria, contemporaries argued. And yet cinchona trees proved difficult to transport over land and sea, and did not easily or universally thrive in new tropical climates. As a result of the growing demand and uncertainty around cinchona, as Pratik Chakrabarti has argued, from the late eighteenth century there was ‘a global scientific obsession’ with finding a ‘substitute’ for cinchona, particularly local alternatives in India and China.1
