White Men in Quarantine: Disease, Race, Commerce and Mobility in the Pacific, 1872.

In July 1872, the steamship Hero underwent quarantine at Sydney's North Head after a case of smallpox was diagnosed. This article brings together the histories of quarantine, white subjectivity and Pacific mobility through an analysis of the Loganiana newspaper produced by the passengers of the Hero during their confinement. The Loganiana provides a unique insight into the formation of white identities through discussions of race, commerce, science and inter-colonial politics. The case provides an important perspective on a transformative period in Australia's border history, and also illuminates the tensions accompanying the transition from an older imperial order to political autonomy in the nineteenth-century Pacific.

Making modern migraine medieval: men of science, Hildegard of Bingen and the life of a retrospective diagnosis.

Charles Singer's retrospective diagnosis of Hildegard of Bingen as a migraine sufferer, first made in 1913, has become commonly accepted. This article uses Hildegard as a case study to shift our focus from a polarised debate about the merits or otherwise of retrospective diagnosis, to examine instead what happens when diagnoses take on lives of their own. It argues that simply championing or rejecting retrospective diagnosis is not enough; that we need instead to appreciate how, at the moment of creation, a diagnosis reflects the significance of particular medical signs and theories in historical context and how, when and why such diagnoses can come to do meaningful work when subsequently mobilised as scientific 'fact'. This article first traces the emergence of a new formulation of migraine in the nineteenth century, then shows how this context enabled Singer to retrospectively diagnose Hildegard's migraine and finally examines some of the ways in which this idea has gained popular and academic currency in the second half of the twentieth century. The case of Hildegard's migraine reminds us of the need to historicise scientific evidence just as rigorously as we historicise our other material and it exposes the cumulative methodological problems that can occur when historians use science, and scientists use history on a casual basis.

From convicts to colonists: the health of prisoners and the voyage to Australia, 1823-53.

From 1815, naval surgeons accompanied all convict voyages from Britain and Ireland to the Australian colonies. As their authority grew, naval surgeons on convict ships increasingly used their medical observations about the health of convicts to make pointed and sustained criticisms of British penal reforms. Beyond their authority at sea, surgeons' journals and correspondence brought debates about penal reform in Britain into direct conversation with debates about colonial transportation. In the 1830s, naval surgeons' claims brought them into conflict with their medical colleagues on land, as well as with the colonial governor, George Arthur. As the surgeons continued their attempts to combat scurvy, their rhetoric changed. By the late 1840s, as convicts' bodies betrayed the disturbing effects of separate confinement as they boarded the convict ships, surgeons could argue convincingly that the voyage itself was a space that could medically, physically and spiritually reform convicts. By the mid-1840s, surgeons took the role of key arbiters of convicts' potential contribution to the Australian colonies.
