Disorderly white communities, which elites associated with crime, poverty, and the transgression of racial boundaries, were often perceived as a destabilising force in the colonial world. Drawing upon the life history and the 1926 fraud trial in Shanghai of a multiply marginal woman named Edith Brentnall, this article explores three key dimensions of the British consular management of colonial criminality on the China coast: concern about the mobility of marginal Europeans and Americans, the ambiguity of national status in the extraterritorial environments of the treaty ports, and a preoccupation with female “delinquency.” Using Brentnall as a common thread to explore the varied textures of “white” criminality in the treaty ports, this article contends that marginal Britons’ misbehaviour took on a heightened significance on imperial peripheries, where patchwork consular justice systems and mobile, cosmopolitan populations impeded monitoring “undesirable” behaviour. Moreover, the management of marginal mobility, which often took the form of circular journeys between East and Southeast Asian port cities, was an overarching concern in British consular excavations of white criminality. The fragmented biographies of individual “undesirables” demonstrate how marginal British subjects exploited gaps in colonial administrative and justice systems, resisted consular intrusions, and actively shaped their life stories’ written records.

It was known from ancient times that vertigo was a malady and that the inner ears of animals contained an intricate network of structures named the labyrinth, whose function was unknown. The flourishing of human vestibular anatomy in the Renaissance period still adhered to age-old notions of traditional spiritual philosophy. In the post-Renaissance period, when science was being redefined and challenging these traditional thoughts, vestibular physiology was born. Started by Flourens, it gathered momentum with Hogyes, Goltz, Breuer, Mach, Crum Brown, Ewald, Brown Sequard and Baginsky in the 19th century. They discovered the role of the vestibular organ in sensing balance and the fine intricacies of vestibular physiology valid to this day. Ménière shattered the concept of traditional aetiology of vertigo and de Cyon challenged the Kantian concept of space. The science catapulted to the modern century. This article traces the history of these pioneers of vestibular physiology.

Thomas Karp Pavlychenko's pioneering investigations on the root systems of crops and weeds and the results of his research on weed biology and ecology at the University of Saskatchewan in the 1930's and 1940's provided the foundation for many of the principles of modern weed science. His classical studies in which he quantified the distribution and length of roots of many plant species continue to be regarded as being of unsurpassed caliber. In addition to his work in the areas of crop ecology and plant competition, Pavlychenko is also noted for his many contributions relating to the cultural and chemical control of weeds. In this paper, a brief chronicle of Pavlychenko's life and major accomplishments during his remarkable career at the University of Saskatchewan and later with the American Chemical and Paint Company is presented.
