Accurate estimation of historical abundance provides an essential baseline for judging the recovery of the great whales. This is particularly challenging for whales hunted prior to twentieth century modern whaling, as population-level catch records are often incomplete. Assessments of whale recovery using pre-modern exploitation indices are therefore rare, despite the intensive, global nature of nineteenth century whaling. Right whales ( Eubalaena spp.) were particularly exploited: slow swimmers with strong fidelity to sheltered calving bays, the species made predictable and easy targets. Here, we present the first integrated population-level assessment of the whaling impact and pre-exploitation abundance of a right whale, the New Zealand southern right whale ( E. australis ). In this assessment, we use a Bayesian population dynamics model integrating multiple data sources: nineteenth century catches, genetic constraints on bottleneck size and individual sightings histories informing abundance and trend. Different catch allocation scenarios are explored to account for uncertainty in the population's offshore distribution. From a pre-exploitation abundance of 28 800–47 100 whales, nineteenth century hunting reduced the population to approximately 30–40 mature females between 1914 and 1926. Today, it stands at less than 12% of pre-exploitation abundance. Despite the challenges of reconstructing historical catches and population boundaries, conservation efforts of historically exploited species benefit from targets for ecological restoration.

Drawing on hemispheric, oceanic, and southern theory approaches, this article argues for the value of considering the nineteenth-century literary cultures of the southern settler colonies of Australia, New Zealand, and South Africa from within an interconnected frame of analysis. First, because of their distinctive historical and structural conditions; second, because of the density of their interregional networks and relations across intersecting oceanic spaces; and third, because of the long history of racialized imperialist imaginaries of the south. This methodological position rethinks current approaches to “British world” studies in two important ways: first, by decoupling the southern settler colonies from studies of settler colonialism in North America; and second, by rebalancing its metropolitan and northern locus by considering south-south networks and relations across a complex of southern islands, oceans, and continents. Without suggesting either that imperial intercultural exchanges with Britain are unimportant or that there is a culturally homogenous body of pan-southern writing, we argue that nineteenth-century literary culture from colonial Australia, New Zealand, and South Africa — what we call a “southern archive” — can provide a counterbalance to northern biases and provide new purchase on nation-centred literary paradigms — one that reveals not just south-south transnational exchanges and structural homologies between southern genres, themes, and forms, but also allows us to acknowledge the important challenges to foundational accounts of national literary canons initiated by southern theory and Indigenous studies scholars.

Background: The prevalence of multiple sclerosis (MS) is not uniform, with a latitudinal gradient of prevalence present in most studies. Understanding the drivers of this gradient may allow a better understanding of the environmental factors involved in MS pathogenesis. Method: The New Zealand national MS prevalence study (NZMSPS) is a cross-sectional study of people with definite MS (DMS) (McDonald criteria 2005) resident in New Zealand on census night, 7 March 2006, utilizing multiple sources of notification. Capture—recapture analysis (CRA) was used to estimate missing cases. Results: Of 2917 people with DMS identified, the crude prevalence was 72.4 per 100,000 population, and 73.1 per 100,000 when age-standardized to the European population. CRA estimated that 96.7% of cases were identified. A latitudinal gradient was seen with MS prevalence increasing three-fold from the North (35°S) to the South (48°S). The gradient was non-uniform; females with relapsing—remitting/secondary-progressive (RRMS/SPMS) disease have a gradient 11 times greater than males with primary-progressive MS ( p < 1 × 10-7). DMS was significantly less common among those of Māori ethnicity. Conclusions: This study confirms the presence of a robust latitudinal gradient of MS prevalence in New Zealand. This gradient is largely driven by European females with the RRMS/SPMS phenotype. These results indicate that the environmental factors that underlie the latitudinal gradient act differentially by gender, ethnicity and MS phenotype. A better understanding of these factors may allow more targeted MS therapies aimed at modifiable environmental triggers at the population level.

Rooted in the extraordinary archive of Quaker physician and humanitarian activist, Dr Thomas Hodgkin, this book explores the efforts of the Aborigines' Protection Society to expose Britain's hypocrisy and imperial crimes in the mid-nineteenth century. Hodgkin's correspondents stretched from Liberia to Lesotho, New Zealand to Texas, Jamaica to Ontario, and Bombay to South Australia; they included scientists, philanthropists, missionaries, systematic colonizers, politicians and indigenous peoples themselves. Debating the best way to protect and advance indigenous rights in an era of burgeoning settler colonialism, they looked back to the lessons and limitations of anti-slavery, lamented the imperial government's disavowal of responsibility for settler colonies, and laid out elaborate (and patronizing) plans for indigenous 'civilization'. Protecting the Empire's Humanity reminds us of the complexity, contradictions and capacious nature of British colonialism and metropolitan 'humanitarianism', illuminating the broad canvas of empire through a distinctive set of British and Indigenous campaigners.

Historians tend to view public health as a quintessentially modern phenomenon, enabled by the emergence of representative democracies, centralised bureaucracies and advanced biomedicine. While social, urban and religious historians have begun chipping away at the entrenched dichotomy between pre/modernity that this view implies, evidence for community prophylactics in earlier eras also emerges from a group of somewhat unexpected sources, namely military manuals. Texts composed for (and often by) army leaders in medieval Latin Europe, East Rome (Byzantium) and other premodern civilisations reflect the topicality of population-level preventative healthcare well before the nineteenth century, thereby broadening the path for historicising public health from a transregional and even global perspective. Moreover, at least throughout the Mediterranean world, military manuals also attest the enduring appeal of Hippocratic and Galenic prophylactics and how that medical tradition continued for centuries to shape the routines and material culture of vulnerable communities such as armies.

If we use the word land to refer to the physical substance, and reserve the word property for the intellectual apparatus that organizes rights to use land, we can say that in colonial New Zealand, the British and the Maori overlaid two dissimilar systems of property on the same land. That difference in legal thought structured each side's perception of what the other was doing, in ways that illustrate unusually clearly the power of law to organize our awareness of phenomena before they reach the level of consciousness. Over the course of the nineteenth century, as the balance of power gradually swung to the side of the British, they were largely able to impose their property system on the Maori. The centrality of property within the thought of both peoples, however, meant that the transformation of Maori into English property rights involved much more than land. Religious belief, engagement with the market economy, political organization—all were bound up in the systems by which both peoples organized property rights in land. To anglicize the Maori property system was to revolutionize Maori life.

James Cowan’s Pictures of Old New Zealand (1930) documents the Partridge Collection of paintings by Gottfried Lindauer in full-page, half-tone illustrations accompanied by historical biographies. Lavish by New Zealand’s publishing standards of 1930, the book originated in an earlier, unillustrated guide to the collection overseen by a much younger Cowan in 1901. This essay discusses the genesis of many biographies in manuscripts solicited by Partridge from his friend James Mackay, a “fixer” between Māori and Pākehā worlds in the late nineteenth century who personally knew many of the subjects. It further argues that Cowan’s Pictures of Old New Zealand deserves recognition as the first significant art monograph to be published in New Zealand.
