1. Changes in the Bodily Framework.-During this period the girl's skeleton not only grows remarkably in size, but is also the subject of well-marked alterations and development. Among the most evident changes are those which occur in the shape and inclination of the pelvis. During the years of childhood the female pelvis has a general resemblance to that of the male, but with the advent of puberty the vertical portion of the hip bones becomes expanded and altered in shape, it becomes more curved, and its inner surface looks less directly forward and more towards its fellow bone of the other side. The brim of the pelvis, which in the child is more or less heart-shaped, becomes a wide oval, and consequently the pelvic girdle gains considerably in width. The heads of the thigh bones not only actually, in consequence of growth, but also relatively, in consequence of change of shape in the pelvis, become more widely separated from each other than they are in childhood, and hence the gait and the manner of running alters greatly in the adult woman. At the same time the angle made by the junction of the spinal column with the back of the pelvis, known as the sacro-vertebral angle, becomes better marked, and this also contributes to the development of the characteristic female type.

Cutting across traditional subject boundaries, Principles of Ecotoxicology, Fourth Edition gives readers an integrated view of ecotoxicology, from molecules to ecosystems. This new edition of a bestselling textbook continues to emphasize principles rather than practice, providing the interdisciplinary perspective and grounding required for research. Organized into three sections, the book first describes the molecular structures, properties, and environmental fate of pollutants. It then deals with the effects of pollutants on living organisms at the molecular, cellular, and individual levels. Moving into population biology and population genetics, the third part of the book addresses a question of great interest to ecologists: What effects do pollutants have at the levels of population, community, and the whole ecosystem? The book also looks at how ecotoxicology is used in the biomonitoring of environmental pollution, the investigation of pollution problems, the conducting of field trials, the study of the development of resistance, and the growing area of environmental risk assessments. Throughout, examples and case studies illustrate the principles. This updated fourth edition includes new material on nanoparticle pollution, bioaccumulation, biomarkers, and chemical warfare in nature, as well as a new chapter on the future directions of ecotoxicology. A concise textbook that will also appeal to practicing ecotoxicologists, it provides a solid basis for understanding what happens to chemicals in the real world, where they go, how they ultimately degrade, and how they affect the individuals and populations that encounter them.

First translation into English of key chronicle for events of the Albigensian Crusade and the attack on heresy, including the siege of the Cathar stronghold, Montsegur. The Albigensian Crusade, which forms the main subject of William of Puylaurens' Chronicle, was a defining episode in the history of France. Launched in 1209 by Pope Innocent III, it was directed against the aristocracy of southernFrance (especially the Counts of Toulouse) who were accused of protecting heresy, and especially Catharism, a dualist heresy which represented a major threat to the Catholic Church. The Crusade ended in 1229 with the defeat of Count Raymond VII of Toulouse. It was followed in the 1230s by the establishment of the Papal Inquisition against heresy. The long-term outcome of the Crusade was the defeat of Catharism, and the establishment of French Royal powerin the region. William of Puylaurens' Chronicle, here translated into English for the first time, is one of the main contemporary accounts of these events. It describes heresy in the south of France in the early 13th century; provides a narrative of the Crusade; and then outlines the growth of the Inquisition and the sustained attack on heresy which followed, including the siege of the Cathar fortress of Montsegur in 1243-44. This translation is accompanied by an introduction, full notes, appendices, and a bibliography.W.A. SIBLY is a former Domus Exhibitioner in Classics at Balliol College, Oxford; M.D. SIBLY read history at Corpus Christi College, Cambridge. They have also translated Peter of Les Vaux de Cernay's History of the Albigensian Crusade (also published by Boydell & Brewer).

One of the first textbooks in this emerging important field of ecology.Most of ecology is about metabolism: the ways that organisms use energy and materials. The energy requirements of individuals - their metabolic rates - vary predictably with their body size and temperature. Ecological interactions are exchanges of energy and materials between organisms and their environments. So metabolic rate affects ecological processes at all levels: individuals, populations, communities and ecosystems. Each chapter focuses on a different process, level of organization, or kind of organism. It lays a conceptual foundation and presents empirical examples. Together, the chapters provide an integrated framework that holds the promise for a unified theory of ecology.

The book is intended to be accessible to upper-level undergraduate, and graduate students, but also of interest to senior scientists. Its easy-to-read chapters and clear illustrations can be used in lecture and seminar courses. Together they make for an authoritative treatment that will inspire future generations to study metabolic ecology.

First English translation of important contemporary source for the history of the Cathar heresy and the Albigensian crusade. The Historia Albigensis is one of the most important sources for the history of the Cathar heresy and the Albigensian crusade. This new translation makes the work available in English for the first time. The Historiawas written between about 1212 and 1218 by Peter, a young monk at the Cistercian abbey of les Vaux-de-Cernay, where his uncle Guy was abbot. Guy took part in the preaching mission against heresy in 1207 and later played an important part in the crusade and became bishop of Carcassonne. Peter several times accompanied his uncle, and not only met those involved in the crusade, but himself witnessed many episodes. The Historiathus contains a wealth offirsthand detail about the personalities and events of the crusade, and about contemporary warfare. An introduction and extensive notes draw on other contemporary sources and on recent scholarship; nine appendices range from the policies of Innocent III to the technical terms used to describe fortifications, also providing translations of other important contemporary sources. W.A. SIBLY read classics at Balliol College, Oxford; his son M.D. SIBLY read history at Corpus Christi College, Cambridge.

Physician, astrologer and occult philosopher, Ebenezer Sibly (1751 99) wrote popular works of medical theory and advice, including Culpeper's English Physician (1789) and this companion volume of 1795. A synthesis of theology, natural philosophy and medical science, the book argues for a microcosmic understanding of the human body as a composite of the four essential elements. An ambitious work, it bears witness to an important era in the development of modern medicine, as Sibly looks to combine an older hermetic tradition with new Enlightenment-era insights into the physical universe. In the final section of the work, Sibly touts his remedies, Lunar Tincture and Solar Tincture, developed to act upon female and male ailments, respectively. Composed from the 'pabulum of the universe', these medicines, Sibly claims, cure everything from gunshot wounds to dog bites.
