Recent studies have fruitfully examined the intersection between early modern science and visual culture by elucidating the functions of images in shaping and disseminating scientific knowledge. Given its rich archival sources, it is possible to extend this line of research in the case of the Royal Society to an examination of attitudes towards images as artifacts—manufactured objects worth commissioning, collecting, and studying. Drawing on existing scholarship and material from the Royal Society Archives, I discuss Fellows’ interests in prints, drawings, varnishes, (...) colorants, images made out of unusual materials, and methods of identifying the painter from a painting. Knowledge of production processes of images was important to members of the Royal Society, not only as connoisseurs and collectors, but also as those interested in a Baconian mastery of material processes, including a “history of trades.” Their antiquarian interests led to discussion of painters’ styles, and they gradually developed a visual memorial to an institution through portraits and other visual records.

The focus of this paper is a fascinating but hitherto unstudied 1742 manuscript treatise by Johannes Daniel Schlichting (1705–1765) titled “Sapientiæ Problema” that contains something extremely rare in the mid-eighteenth century: a full-blown speculative cosmogony. As this article reveals, Schlichting developed a distinctive vital liquid matter in an effort to account for the generation of all natural bodies and combat the stamina-based theories that were dominant in his day. He hoped that his treatise would be published in the Philosophical Transactions (...) of the Royal Society, but an accompanying abridgment by the FRS Henry Baker (1698–1774) strongly implies that Schlichting’s speculative bent and desire to divulge causal explanations were unacceptable to the Englishman and generally ill-suited to the intellectual climate of mid-century England.

Eighteenth century river hydraulics used both theory and measurement to address problems of flood safety, navigation and defense related to the rivers. In the late eighteenth century the Dutch overseer of the rivers, Christiaan Brunings, integrated hydraulic theory and meteorological practices, which enabled him to design a unique instrument for measuring river flow. The question is whether the unprecedented detail of measurements fits the putative empirical stance in the eighteenth century. The interactions between theory, instrument, measurement, and other knowledge practices (...) are here assessed using experiences in similar measurement practices. I argue that Brunings had theoretical and embodied understanding of hydrodynamics, as he knew how to design an instrument for flow measurement of sufficient accuracy for his purpose in the sociopolitical context of river management.

ABSTRACT In an unpublished anatomical treatise written around 1670, the English anatomist and fellow of the Royal Society of London Edmund King proposed that the human body was ultimately an assemblage of tubes and contained liquids. Without literally seeing every of its constituents to be tubular, how did King come to posit a tubular body? This article tackles the question by examining King’s inquiry about the pulse against his framing of the circulatory system into a universally tubular model. Asking how (...) King registered this model despite the limited visibility of vascularity in practice, I discuss the place of analogy in his anatomical observation. I argue that analogy constituted an essential strategy for extending what King had perceived to account for the hardly perceptible nuances of the human body. I concentrate on two of his analogies, in which the artery was compared to the cord and the ureter. These two analogies revealed remarkable epistemic potency in representing and reasoning the pulse as the inherent motion of the living artery. They suggest that in seventeenth-century observation accounts, analogy was not simply a rhetoric suspicious of violating the principle of scientific empiricism; rather, they opened up ways of seeing and imagining nature.
