    Strange reading: Keith Windschuttle on race, Asia and White Australia

    Full text link
    In his recently published book, The White Australia Policy, Keith Windschuttle accuses academic historians of errors of fact and judgement in their accounts of white Australia. This article examines these claims of exaggeration and distortion with particular reference to the nature and meaning of race, racism and representations of Asia in Australian history. The article rejects Winschuttle\u27s sweeping claim that academic historians have sought to make Australia appear a much more racist society than the historical record would suggest.<br /

    The Early Royal Society and Visual Culture

    Recent studies have fruitfully examined the intersection between early modern science and visual culture by elucidating the functions of images in shaping and disseminating scientific knowledge. Given its rich archival sources, it is possible to extend this line of research in the case of the Royal Society to an examination of attitudes towards images as artefacts –manufactured objects worth commissioning, collecting and studying. Drawing on existing scholarship and material from the Royal Society Archives, I discuss Fellows’ interests in prints, drawings, varnishes, colorants, images made out of unusual materials, and methods of identifying the painter from a painting. Knowledge of production processes of images was important to members of the Royal Society, not only as connoisseurs and collectors, but also as those interested in a Baconian mastery of material processes, including a “history of trades”. Their antiquarian interests led to discussion of painters’ styles, and they gradually developed a visual memorial to an institution through portraits and other visual records.AH/M001938/1 (AHRC

    Enhanced H and F incorporation in borian olivine

    No full text
    B-containing olivine from the Tayozhnoye Fe deposit (Siberia, Russia) has unusually high H and F contents of 0.012 H and 0.026-0.043 F per formula unit of four O atoms. There are a minimum of eight infrared O-H absorption bands, none of which correlates with the known O-H band frequencies of hydrous magnesium silicates. The O-H band at 3672 cm^(-1) has not been observed in previously published olivine spectra. Transmission electron microscopy indicates substantial replacement of olivine by clinohumite and disordered mixtures of olivine and humite-group minerals near the rims of the olivine grains, whereas the interiors of the olivine grains contain regions of unaltered olivine structure. H_2O contents calculated from the defect stoichiometry and defect density are approximately one-tenth of the total H_2O content estimated from the infrared data. The O-H bands, therefore, are believed to reflect the presence of OH within the olivine crystal structure. Infrared-active stretching vibrations at 758, 1164, and 1257 cm^(-1) are consistent with the presence of [4]BO_4 groups within the olivine structure. Our data represent the first direct evidence of the coupled substitution B(F,OH)Si_(-1),O_(-1), in orthosilicate minerals. As a potential carrier of B, F, and H in the subducted oceanic lithosphere, olivine may play a key role in recycling these elements into the mantle
