The development and evolution of “cerebral thermometry”: Clinical applications of a nineteenth-century approach to cerebral localization and neurological diagnosis

ABSTRACT

Surface thermometers were developed in the latter half of the nineteenth century. In 1877, Broca, already famous for his contributions to the cerebral localization of nonfluent aphasia, presented his first clinical observations on cranial surface temperatures: In two cases, cranial surface temperatures were decreased over a middle cerebral artery infarction, and increased in surrounding areas, which Broca attributed to “compensatory hyperaemia.” As Broca made apparent in a later report in 1879, he had used a “thermometric crown,” an apparatus consisting of six to eight large-reservoir mercury thermometers strapped against the head. Following Broca’s report, American neurologists reported cases in which cranial surface temperatures were increased either locally over a superficial brain tumor or globally with a cerebral abscess. Despite promising anecdotal reports, contemporaries recognized that significant technical and practical problems limited its accuracy, reliability, and clinical utility. Advocates never demonstrated that this technology provided significant marginal benefit to the medical history and physical examination. The technique fell out of fashion before 1900, though some early advocates promoted it into the early twentieth century. It was ultimately replaced by more effective technologies for cerebral localization and neurological diagnosis.     

Passion,Parliament, and the Pen: Articulations of Female Citizenship in Britain,c.1790–1890

Among the plethora of political shifts that defined the Age of Reform, this article will uncover a female narrative of changing conceptions of citizenship, asserting that, despite their formal exclusion, women articulated a distinctly female understanding of citizenship through writing. Furthermore, it will explore the significance of parliament to women's experiences. The spaces in which citizenship was performed are integral to understanding its conception, and the significance of the franchise in 19th-century political culture made parliament a fundamental space for those pursuing citizenship rights. Women from a diverse range of backgrounds articulated their inherently female experiences in their writing as they engaged with the discourses of citizenship that surrounded them. A collection of central themes and issues characterised their writing: honour and legality; representation and the franchise; local and municipal politics; marriage; education; and professional and employment opportunities. These texts illuminate the emerging self-conception of female citizenship by women whose lived experiences were coloured by the historical shifts of reform. Consequently, the tapestry of these texts is formed of an intricately connected web of threads that both merge and deviate from one another around their individual focus, intention, or argument. However, collectively they suggest a resoundingly harmonious image, demonstrating that, although varying between individuals, a whole multitude of women from across society were experiencing this realisation of their right to equal citizenship.     

The laryngoscope and nineteenth-century British understanding of laryngeal movements

ABSTRACT

The source of the human voice is obscured from view. The development of the laryngoscope in the late 1850s provided the potential to see the action of the vocal folds during speaking for the first time. This new instrument materially contributed to the understanding of vocal fold neuroanatomy, neurophysiology, and neuropathology. The laryngoscope led to elaborated understanding of disorders that previously were determined by changes in sound. The objective of this paper is to detail the consequences of this novel visualization of the larynx, and to trace how it aided in the development of understanding of the movements of the vocal folds. This is demonstrated through an examination of the activities and practices of a group of London clinicians in the second half of the nineteenth century.     

‘High Politics’ and its Intellectual Contexts*

Recent interest in the historiography of ‘high politics’ has centred mainly on historians writing in the 1960s and 1970s, above all Maurice Cowling. Less attention has been paid to the modified agendas pursued by the next generation of scholars. This essay explores some pioneering attempts to make sense of the structural relationships between 19th‐century British ‘high politics’ and its ‘intellectual’ contexts, focusing on a cluster of seminal 1980s studies by the historians Michael Bentley, Richard Brent, Boyd Hilton, and Jonathan Parry. Together, these works demanded a fundamental rethinking of how Victorian politics operated.     

Recognizing synesthesia on the international stage: The first scientific symposium on synesthesia (at The International Conference of Physiological Psychology,Paris, 1889)

ABSTRACT

At the first ever worldwide international conference of psychology in Paris, 1889, one symposium included a round-table event devoted entirely to the neurodevelopmental condition of synesthesia. Details of this seminal gathering on synesthesia and its international reception have been lost to historical obscurity. A synesthesia study committee emerged from this meeting, as well as a new research tool. Moreover, the scientific findings discussed during this symposium would be echoed over a hundred years later, when a new wave of synesthesia research in the late-twentieth century arose. This article sheds new light on this seminal gathering and aims to answer the following historical questions: Why was synesthesia included in this conference? What science was discussed? Who were the members of the committee and how did they come to be involved? What were their contributions to synesthesia research before, during, and after the conference? What has history shown us about the impact of this symposium on the science of synesthesia?     

The Painted Chamber at Westminster and the Openings of Parliament, 1399–1484*

The aim of this article is to investigate the use of the Painted Chamber in the Palace of Westminster as a parliamentary space in the 15th century, focusing on 41 openings of parliament held there between 1399 and 1484. It will examine the history and images of the Painted Chamber and the procedures of the opening of parliament through a combination of historical, art historical, and archaeological sources, scholarship and methodologies. It will argue that the Painted Chamber and the openings of parliament therein were tools used by the crown to establish a dynamic between itself and the Commons in which the crown claimed its right to authority but also encouraged a political dialogue. Furthermore, it will argue that this need for dialogue was a response to the growing political influence of the Commons.     

Ruling from afar: government and information management in late medieval Sicily

In 1412 Sicily lost its independence and became part of the Crown of Aragon. To rule the island, the new monarchs developed a system of long-distance government, through the action of local viceroys. But how did this system work in practice? This article engages with the lively historiographical debate about late medieval Sicily and more generally the Aragonese conglomerate by examining the series of libri quictacionum (‘books of quittances’) produced by the financial office, the Conservatoria regii patrimonii. It shows that the management of information – by means of a new genre of documents, an innovative record-keeping system and an apparatus of marginal annotations – became crucial in establishing effective government at a distance and in strengthening royal control over Sicilian institutions and officers. Moreover, these books and the documents they encompass highlight the social dynamics of the island and the emergence of an urban class: the Aragonese promoted the inclusion of the principal members of the latter into central government by granting them offices.     

Parliamentary Divorce, 1700–1857

Divorce by parliament in the 18th and early 19th centuries was long considered to be the preserve of the wealthy and the upper ranks of society. But while social standing has guided historians' analysis of those who obtained divorce, the standing of those who failed to obtain divorce has been largely overlooked. If rank or status is to serve true analytical purpose, the successful must be set against the failed. Juxtaposing the successes and failures by group across the period reveals that the upper echelons of society were by no means preferred. Even distinctive cases – for instance of multiple failure – were not decided on rank. Status is ultimately shown to be of limited significance. Although the sources are not at all explicit, from the analysis of certain specific cases, it would appear that moral and legal judgments (for example, on collusion) far outweighed any social prejudices.
