Spirometry, measurement, and race in the nineteenth century

Race correction is a common practice in contemporary pulmonary medicine that involves mathematical adjustment of lung capacity measurements in populations designated as "black" using standards derived largely from populations designated as "white." This article traces the history of the racialization and gendering of spirometry through an examination of the ideas and practices related to lung capacity measurements that circulated between Britain and the United States in the nineteenth century. Lung capacity was first conceptualized as a discrete entity of potential use in the diagnosis of pulmonary disease and monitoring of the vitality of the armed forces and other public servants in spirometric studies conducted in mid-nineteenth-century Britain. The spirometer was then imported to the United States and used to measure the capacity of the lungs in a large study of black and white soldiers in the Union Army sponsored by the U.S. Sanitary Commission at the end of the Civil War. Despite contrary findings and contestation by leading black intellectuals, the notion of mean differences between racial groups in the capacity of the lungs became deeply entrenched in the popular and scientific imagination in the nineteenth century, leaving unexamined both the racial categories deployed to organize data and the conditions of life that shape lung function.     

Comments on economic change and the prehistoric fur trade in Northern Sweden

In this study, we used stable isotope analysis and radiocarbon dating to study diet, mobility and chronology in two late medieval/historical coastal populations in northern Norway. We have shown that the individuals buried at Kirkegårdsøya date between 1331 and 1953 cal AD and had a homogenous marine diet, whereas the individuals buried at Gullholmen had a more heterogeneous diet, consisting of both terrestrial and marine proteins and date between 1661 and 1953 cal AD. We have demonstrated that reindeer protein was not an important part of their diet, and also discussed the importance of correcting for the marine reservoir effect in populations with a coastal subsistence. Our interpretation is that individuals buried at Kirkegårdsøya primarily belonged to a Coastal Sámi community, although Norwegians with a similar diet (and likely comprising a minor population in the area) cannot be ruled out. The more varied diet and mobility at Gullholmen could, as predicted, indicate that these individuals may have had a more diverse cultural affinity.     

Effects of a nineteenth century below-knee amputation and prosthesis on femoral morphology

Access to the lower limbs from a historically-identified nineteenth century below-knee amputee who had worn a hardwood ectoprosthesis for an extended time prior to death provides a natural experiment for investigating the morphological and histological effects of the resulting altered mechanical environment. Osteometry (measuring total bone size), cross-sectional geometry (bending and axial rigidity) and histology (bone turnover rate) are assessed. A reduction in size and geometric strength, along with an increase in cortical bone turnover, indicate that the midshaft and distal regions from the affected femur were partially shielded from functional strain. Structural compliance of the prosthesis, probably originating from design and material of manufacture, to some degree preserved the mechanical and morphological integrity of the proximal subtrochanteric region. The results of this case study are consistent with contemporary theory in skeletal biomechanics, for example, Frost's Mechanostat, which suggests that insufficient functional strain promotes intracortical remodelling and endosteal expansion.     

Gender, nature, empire: women naturalists in nineteenth century British travel literature

Among the many British women abroad in the late nineteenth century were a number of travellers who toured the American West with a naturalist's pen and sketchbook. California, with its giant sequoias and redwoods, scenic Yosemite Valley and Sierra Nevada, and the Mediterranean flora of the southern coasts, especially attracted travellers with a naturalist orientation. We examine the botanical and naturalist writings and art of two well-known (and well-heeled) world travellers – Constance Gordon Cumming and Marianne North – and another more obscure British aristocrat, Theodora Guest, sister of the Duke of Westminster, who travelled in California in the late nineteenth century. We examine relationships among these elite women's association with the Romantic aesthetic and naturalist traditions, natural sciences, class-based associations between women and flowers, and emergent environmentalism. The works of these women indicate the process by which natural history rhetorics and styles became embedded within gender, class, and imperial relations; and how the division of natural history into professional and amateur domains relegated women to discursive margins.     

Between cosmopolitanism and nationhood: Italian opera in the early nineteenth century

The revival of interest in music evident in recent historiography has led to an investigation of the specifically transnational nature of musical languages and practices. This article explores the possibility of re-reading in a transnational perspective the classical theme of the relationship between the Risorgimento and opera. It focuses on two different points of view: on the one hand, the construction of the librettos as a delicate balance between European romantic narratives and dramatic themes evoking nationalistic sentiments; on the other, the fact that ideas and practices of the theatre as a vehicle of political mobilisation developed in a broad international context where Mazzini and many other nationalists found inspiration in multinational political experiences and discourses. The article concludes by saying that the meanings of terms such as cosmopolitanism and nationalism need to be carefully weighed when we look at nineteenth-century opera production. Only in the closing decades of the century did genuine competition between national traditions arise, which led in Italy to a veritable ‘obsession’ with ‘Italianness’ in music.     

An uninhabited waste: transforming the Grand Prairie in nineteenth century Illinois, USA

Today the area once known as the Grand Prairie in the American Midwest is best known for its high agricultural productivity and monoculture. Little of the original prairie landscape that gave the region its name remains. Prior to white settlement, the region was perceived as swampy, dangerous, unhealthy and unfit for agriculture. This ‘uninhabited waste’ and ‘giant emporium of malaria’ embodied the type of landscapes settlers initially tried to avoid. Ultimately, perceptions of the Grand Prairie landscape as well as the physical landscape itself were altered by settlement and improving drainage technology. This paper aims to link changes in the way the central Illinois landscape was imagined and perceived, with the subsequent environmental transformation that resulted in the near total elimination of tallgrass prairie and the wholesale alteration of regional hydrology through channelization and agricultural drainage.     

An element of thought: phosphorus and mental philosophy in the nineteenth century

Georges Cabanis (1757-1808), through his writings on the relation of the physical and moral, or psychological, aspects of man, left a legacy that made the study of mental activity a part of physiology. His views on the importance of phosphorus to the function of the brain thrust that element into a prominent stream of research that involved many investigators in several countries. Although that particular stream eventually dried up, its influence remained: by the beginning of the twentieth century basic medical science had become well set on studies of the mind-body relationship.
