Book Description
A professor at twenty-one and member of the Napoleon's Egyptian expedition at twenty-six, Geoffroy Saint-Hilaire was a man of one idea, which he formulated when he was twenty-four. Nature, he thought, had formed all living beings with one single plan. This was a revolutionary idea—and one vigorously opposed by Geoffroy's colleague Georges Cuvier, a great anatomist and one of the giants of French science. In 1830, their long-running disagreement erupted into furious public debate. Geoffroy argued that all vertebrates shared the same basic body plan not just with each other but with insects as well. Cuvier strenuously disputed this idea, which he saw as tantamount to a belief in "transformism"—arguing instead that each species had its own special and permanent form. With Geoffroy Saint-Hilaire, Hervé Le Guyader provides an analysis not only of that infamous debate but also of Geoffroy's bold intuitions about anatomy and development. Featuring Geoffroy's published version of the 1830 debates—translated into English for the first time—the book also illustrates how Geoffroy's prescient insights foreshadowed some of the most recent discoveries in evolutionary and developmental biology.

Book Description
The Biology of Stentor summarizes all that has been learned about the biology of a certain group of ciliate protozoa: the stentors. Topics covered range from form and function in Stentor to behavior, fine structure, growth and division, and reorganization. Regeneration is also discussed, along with polarity, metabolism, genetics, and primordium development. This volume is comprised of 20 chapters and begins with a characterization of Stentor, with emphasis on its particular advantages in addressing general problems of biology. The reader is then introduced to form and function in Stentor, particularly S. coeruleus. The following chapters focus on the behavior (food selection, swimming, response to light, etc.) of stentors and the fine points of structure in terms of which this behavior is to be explained and which demonstrate the highly complex and precise achievements of morphogenesis. The remaining chapters explore growth and division in Stentor as well as the course of reorganization and regeneration; development of the oral primordium and how it is activated and inhibited; rate of regeneration in relation to the polar axis; fusion masses of whole stentors; and reconstitution in disarranged stentors. Various species of Stentor are also described, together with the techniques used to study them. The final chapter deals with hypotheses concerning the morphogenesis of ciliates. This book will be of interest to students and practitioners of biology and physiology.

Book Description
During the nineteenth century, words like 'intersex' and 'trans' had not yet been invented to describe individuals whose bodies, or senses of self, conflicted with binary sex. But that does not mean that such people did not exist. In nineteenth-century France, case studies filled medical journals, high-profile trials captured headlines, and doctors staked their reputations on sex determinations only to have them later reversed by colleagues. While medical experts fought over what separated a man from a woman, novelists began to explore debates about binary sex and describe the experiences of gender-ambiguous characters. Anne Linton discusses over 200 newly-uncovered case studies while offering fresh readings of literature by several famous writers of the period, as well as long-overlooked popular fiction. This landmark contribution to the history of sexuality is the first book to examine intersex in both medicine and literature, sensitively relating historical 'hermaphrodism' to contemporary intersex activism and scholarship.

Book Description
Biological Time, Historical Time presents a new approach to 19th century thought and literature: by focussing on the subject of time, it offers a new perspective on the exchanges between French and German literary texts on the one hand and scientific disciplines on the other. Hence, the rivalling influences of the historical sciences and of the life sciences on literary texts are explored, texts from various scientific domains – medicine, natural history, biology, history, and multiple forms of vulgarisation – are investigated. Literary texts are analysed in their participation in and transformation of the scientific imagination. Special attention is accorded to the temporal dimension: this allows for an innovative account of key concepts of 19th century culture.

Book Description
Jean Octave Edmond Perrier was a French zoologist who lived through the tumult of British Darwinism and Lyellism, and reminds us in this revealing account that French scientists had much to contribute to such perennial topics as evolution, catastrophism and creationism. While very much a product of the Third Republic, Perrier’s account also aimed to outline timeless issues and permanent advances in taxonomic and developmental biology since classical Greece and Rome. In this aim he succeeds with surprisingly modern perspectives for a book first published in 1884. Perrier was born May 9, 1844 at Tulle, the son of the principal of a school which now bears his name, Lycée Edmond Perrier. In 1864 he was accepted to the École Normale Supérieure, where he was strongly influenced by Louis Pasteur and Henri de Lacaze-Duthiers. After working for three years at a high school in Agen, he obtained a post of naturalist-aid at the Muséum National d'Histoire Naturelle (1868), advancing in that institution to Chair of Natural History of Molluscs, Worms and Corals (1876–1903) and then Director of the museum (1900–1919) and Chair of Comparative Anatomy (1903–1921). Previous directors of the museum included many of the scientists he discusses in this book: George Cuvier (1822–1823, 1826–1827, 1830–1831), Isidore Geoffrey St Hilaire (1860– 1861), and Alphonse Milne-Edwards (1891–1900). Perrier’s own research on echinoderms and earthworms took him on several expeditions in 1880-1885, mostly to Atlantic and Mediterranean coasts, but also to the Caribbean.

Book Description
Modern biology is increasingly focused on the role of repetitive anatomical structures in the embryological construction of organisms. The discovery of the homeobox (Hox) genes by Edward Lewis in 1978 ushered in a series of stunning revelations such as the fundamental commonality of insect segments and mammalian vertebrae - a wild and ridiculed idea first proposed by Etienne Geoffroy Saint-Hilaire in 1822 that has now been proven correct. Axial Character Seriation in Mammals is an unabridged edition of the 1986 Harvard University PhD Thesis of Aaron G. Filler, MD, PhD that pioneered our modern reassessment of mammalian vertebrae in the light of the new homeotic biology. As Dr. Filler points out in fascinating detail, the leading explanations of similarity among animals before Darwin were arrayed around the vertebrae of the spine in works by Sir Richard Owen, Johann Wolfgang Goethe and Geoffroy Saint-Hilaire. This was the theoretical structure that was overturned and demolished by Darwin's ideas about similarity due to common descent. In a stunning reversal, modern homeotic genetics has shown that repeating structures are indeed critical to understanding animal similarity. This work is the first study of the modern era that views vertebrae as a key to unlocking the way in which Nature has organized repeating biological structures. For the 150 years since the Great Academy Debate of 1830 appeared to demolish Geoffroy Saint-Hilaire's ideas, vertebrae have been seen as no more than some bones in Vertebrate animals that are involved in support and locomotion. Axial Character Seriation in Mammals, however, explores the fascinating traces of how the morphogenetic genes sculpt and organize serially repeating structures, thus re-establishing the vertebrae as a legitimate and compelling subject of modern science.
