This article engages the much-debated role of mathematics in Bacon's philosophy and inductive method at large. The many references to mathematics in Bacon's works are considered in the context of the humanist reform of the curriculum studiorum and, in particular, through a comparison with the kinds of natural and intellectual subtlety as they are defined by many sixteenth-century authors, including Cardano, Scaliger and Montaigne. Additionally, this article gives a nuanced background to the ‘subtlety’ commonly thought to have been eschewed by Bacon and by Bacon's self-proclaimed followers in the Royal Society of London. The aim of this article is ultimately to demonstrate that Bacon did not reject the use of mathematics in natural philosophy altogether. Instead, he hoped that following the Great Instauration a kind of non-abstract mathematics could be founded: a kind of mathematics which was to serve natural philosophy by enabling men to grasp the intrinsic subtlety of nature. Rather than mathematizing nature, it was mathematics that needed to be ‘naturalized’.

The Catalogue of Scientific Papers, published by the Royal Society of London beginning in 1867, projected back to the beginning of the nineteenth century a novel vision of the history of science in which knowledge was built up out of discrete papers each connected to an author. Its construction was an act of canon formation that helped naturalize the idea that scientific publishing consisted of special kinds of texts and authors that were set apart from the wider landscape of publishing. By recovering the decisions and struggles through which the Catalogue was assembled, this essay aims to contribute to current efforts to denaturalize the scientific paper as the dominant genre of scientific life. By privileging a specific representation of the course of a scientific life as a list of papers, the Catalogue helped shape underlying assumptions about the most valuable fruits of a scientific career. Its enumerated lists of authors’ periodical publications were quickly put to use as a means of measuring scientific productivity and reputation, as well as by writers of biography and history. Although it was first conceived as a search technology, this essay locates the Catalogue’s most consequential legacy in its uses as a technology of valuation.

Following the conquest of Algiers and its surrounding territory by the French army in 1830, officers noted an abundance of standing stones in this region of North Africa. Although they attracted considerably less attention among their cohort than more familiar Roman monuments such as triumphal arches and bridges, these prehistoric remains were similar to formations found in Brittany and other parts of France. The first effort to document these remains occurred in 1863, when Laurent-Charles Féraud, a French army interpreter, recorded thousands of dolmens and stone formations south-west of Constantine. Alleging that these constructions were Gallic, Féraud hypothesized the close affinity of the French, who claimed descent from the ancient Gauls, with the early inhabitants of North Africa. After Féraud's claims met with scepticism among many prehistorians, French scholars argued that these remains were constructed by the ancestors of the Berbers (Kabyles in contemporary parlance), whom they hypothesized had been dominated by a blond race of European origin. Using craniometric statistics of human remains found in the vicinity of the standing stones to propose a genealogy of the Kabyles, French administrators in Algeria thereafter suggested that their mixed origins allowed them to adapt more easily than the Arab population to French colonial governance. This case study at the intersection of prehistoric archaeology, ancient history and craniology exposes how genealogical (and racial) classification made signal contributions to French colonial ideology and policy between the 1860s and 1880s.

In 1946, the British biochemist Joseph Needham returned from a four-year stay in China. Needham scholars have considered this visit as a revelatory period that paved the way for his famous book series Science and Civilization in China (SCC). Surprisingly, however, Needham's actual time in China has remained largely unstudied over the last seventy years. As director of the Sino-British Scientific Cooperation Office, Needham travelled throughout Free China to promote cooperation between British and Chinese scientists to contain the Japanese invasion during the Second World War. By rediscovering Needham's peregrinations, this paper re-examines the origins of his fascination for China. First, it contests the widely held idea that this Chinese episode is quite separate and different from Needham's first half-life as a leftist scientist. Second, it demonstrates how the political and philosophical commitments he inherited from the social relations of science movement, and his biochemical research, shaped his interest in China's past. Finally, this paper recounts these forgotten years to reveal their implications for his later pursuits as historian of science and as director of the natural-science division of UNESCO. It highlights how, while in China, Needham co-constituted the philosophical tenets of his scientific programme at UNESCO and the conceptual foundations of his SCC.

This round table discussion takes the diversity of discourse and practice shaping modern knowledge about childhood as an opportunity to engage with recent historiographical approaches in the history of science. It draws attention to symmetries and references among scientific, material, literary and artistic cultures and their respective forms of knowledge. The five participating scholars come from various fields in the humanities and social sciences and allude to historiographical and methodological questions through a range of examples. Topics include the emergence of children's rooms in US consumer magazines, research on the unborn in nineteenth-century sciences of development, the framing of autism in nascent child psychiatry, German literary discourses about the child's initiation into writing, and the sociopolitics of racial identity in the photographic depiction of African American infant corpses in the early twentieth century. Throughout the course of the paper, childhood emerges as a topic particularly amenable to interdisciplinary perspectives that take the history of science as part of a broader history of knowledge.
