  • In South Kensington, C. 1850-1900
    JEWELS OF THE NATURAL HISTORY MUSEUM: GENDERED AESTHETICS IN SOUTH KENSINGTON, C. 1850-1900 PANDORA KATHLEEN CRUISE SYPEREK PH.D. HISTORY OF ART UCL 2 I, PANDORA KATHLEEN CRUISE SYPEREK confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. ______________________________________________ 3 ABSTRACT Several collections of brilliant objects were put on display following the opening of the British Museum (Natural History) in South Kensington in 1881. These objects resemble jewels both in their exquisite lustre and in their hybrid status between nature and culture, science and art. This thesis asks how these jewel-like hybrids – including shiny preserved beetles, iridescent taxidermised hummingbirds, translucent glass jellyfish as well as crystals and minerals themselves – functioned outside of normative gender expectations of Victorian museums and scientific culture. Such displays’ dazzling spectacles refract the linear expectations of earlier natural history taxonomies and confound the narrative of evolutionary habitat dioramas. As such, they challenge the hierarchies underlying both orders and their implications for gender, race and class. Objects on display are compared with relevant cultural phenomena including museum architecture, natural history illustration, literature, commercial display, decorative art and dress, and evaluated in light of issues such as transgressive animal sexualities, the performativity of objects, technologies of visualisation and contemporary aesthetic and evolutionary theory. Feminist theory in the history of science and new materialist philosophy by Donna Haraway, Elizabeth Grosz, Karen Barad and Rosi Braidotti inform analysis into how objects on display complicate nature/culture binaries in the museum of natural history.

  • The Biology of Marine Mammals
    Romero, A. 2009. The Biology of Marine Mammals. The Biology of Marine Mammals Aldemaro Romero, Ph.D. Arkansas State University Jonesboro, AR 2009 2 INTRODUCTION Dear students, 3 Chapter 1 Introduction to Marine Mammals 1.1. Overture Humans have always been fascinated with marine mammals. These creatures have been the basis of mythical tales since Antiquity. For centuries naturalists classified them as fish. Today they are symbols of the environmental movement as well as the source of heated controversies: whether we are dealing with the clubbing pub seals in the Arctic or whaling by industrialized nations, marine mammals continue to be a hot issue in science, politics, economics, and ethics. But if we want to better understand these issues, we need to learn more about marine mammal biology. The problem is that, despite increased research efforts, only in the last two decades we have made significant progress in learning about these creatures. And yet, that knowledge is largely limited to a handful of species because they are either relatively easy to observe in nature or because they can be studied in captivity. Still, because of television documentaries, ‘coffee-table’ books, displays in many aquaria around the world, and a growing whale and dolphin watching industry, people believe that they have a certain familiarity with many species of marine mammals (for more on the relationship between humans and marine mammals such as whales, see Ellis 1991, Forestell 2002). As late as 2002, a new species of beaked whale was being reported (Delbout et al. 2002), in 2003 a new species of baleen whale was described (Wada et al.

MARTIN’S LANE, W C., printers in Ordinary to Her Majesty. MDCCCLXXXVIII. ADVERTISEMENT. The Committee appointed by the Royal Society to direct the publication of the Philosophical Transactions take this opportunity to acquaint the public that it fully appears, as well from the Council-books and Journals of the Society as from repeated declarations which have been made in several former , that the printing of them was always, from time to time, the single act of the respective Secretaries till the Forty-seventh Volume; the Society, as a Body, never interesting themselves any further in their publication than by occasionally recommending the revival of them to some of their Secretaries, when, from the particular circumstances of their affairs, the Transactions had happened for any length of time to be intermitted. And this seems principally to have been done with a view to satisfy the public that their usual meetings were then continued, for the improvement of knowledge and benefit of mankind : the great ends of their first institution by the Boyal Charters, and which they have ever since steadily pursued. But the Society being of late years greatly enlarged, and their communications more numerous, it was thought advisable that a Committee of their members should be appointed to reconsider the papers read before them, and select out of them such as. they should judge most proper for publication in the future Transactions; which was accordingly done upon the 26th of March, 1752.

CARRINGTON BOLTON. 1t FROM THE SMITHSONIAN REPORT FOR 1882. WASHINGTON: GOVERNMENT PRINTING OFFICE. 1883. ^ \ CHEMISTRY. By H. Carhington Bolton, Ph. D., Professor of Chemistry in Trinity College, Hartford, Conn. The year 1882 is marked by great industry in all departments of •chemistry; no startling announcements have been made, but several extremely interesting syntheses of organic bodies have been accom- plished, viz, tyrosine and uric acid, both of the animal organism. Great activity is noted in the revision of the atomic weights. Progress has been made in unraveling the knotty problem of the rare earths in cerite, samarskite, and gadolinite, but no satisfactory conclusions have been reached as to the existence of the larger number of elementary bodies announced since 1877. In the brief space at our disposal we can barely note the salient fea- tures of the year's work in a series of short abstracts, and these we con- fine chiefly to pure chemistry, paying little attention to analytical and industrial chemistry. Periodical literature, devoted exclusively to chem- istry and its applications, is becoming voluminous ; the fifteen principal journals of America, England, France, and Germany publish annually about 18,000 pages; in this rough estimate journals of physics and transactions of societies are not included, and both classes of serials contain much chemical'material.

The colouring matter, however, does not exist as such in the plant, but in the form of a glucoside. This glucoside called rubian or ruberythric acid undergoes hydrolysis under the influence of a ferment, called erythrozym [sic] also cont[aine]d in the plant. No action takes place so long as the plant is living, but when it is cut and the roots are left in a moist condition, alizarine separates out. + 26 28OH14 H2OCO 14HO84O 2C61HOH 26O Ruberythric acid alizarinei glucose The above equation represents the change according to Graebe and Liebermann.
