An invaluable information source about cast iron holloware of the pre-Griswold and Wagner era for collectors, museum curators, reenactors, and hearth cooking aficionados. It is the first book to document cast iron pots, skillets, spiders, pans, kettles, teakettles, Dutch ovens, and mortars, plus several items in brass, from the seventeenth through nineteenth centuries, spanning the years 1645 to 1900. Over 350 photos illustrate identifiable changes in the manufacturing technologies and the vessel forms. Line drawings and detail photos enable the reader to correctly date the objects they find. The engaging text is a product of forty years of collecting and wide-ranging research. Most of the vessels are illustrated in print for the first time. Many of these objects have been seen occasionally in antiques shops or at auctions, but they have never before been identified in the literature. This will be a standard reference book for many years to come.

In addition to reviewing key findings within the field of human-animal interactions, each chapter emphasizes skills on both the human and dog ends of the leash and makes recommendations for research-informed best practices. To support readers, the book culminates with checklists and training resources to serve as a quick reference for readers. This book will be of great interest for practitioners, in-service professionals, and researchers in the fields of canine-assisted interventions and counseling.

John Tyler Bonner, one of our most distinguished and creative biologists, here offers a completely new perspective on the role of size in biology. In his hallmark friendly style, he explores the universal impact of being the right size. By examining stories ranging from Alice in Wonderland to Gulliver's Travels, he shows that humans have always been fascinated by things big and small. Why then does size always reside on the fringes of science and never on the center stage? Why do biologists and others ponder size only when studying something else—running speed, life span, or metabolism? Why Size Matters, a pioneering book of big ideas in a compact size, gives size its due by presenting a profound yet lucid overview of what we know about its role in the living world. Bonner argues that size really does matter—that it is the supreme and universal determinant of what any organism can be and do. For example, because tiny creatures are subject primarily to forces of cohesion and larger beasts to gravity, a fly can easily walk up a wall, something we humans cannot even begin to imagine doing. Bonner introduces us to size through the giants and dwarfs of human, animal, and plant history and then explores questions including the physics of size as it affects biology, the evolution of size over geological time, and the role of size in the function and longevity of living things. As this elegantly written book shows, size affects life in its every aspect. It is a universal frame from which nothing escapes.

John Tyler Bonner, a major participant in the development of biology as an experimental science, is the author not only of important monographs but also of a wonderfully readable book, Life Cycles, which is both a personal memoir and a profound commentary on the central themes of biology. This volume of essays presents new material that extends the concepts from Life Cycles and his other writings. Its originality lies in comparing key basic biological processes at different levels, from molecular interactions through multicellular development to behavior and social interactions. The first chapter in the book discusses self-organization and natural selection; the second, competition and natural selection; and the third, gene accumulation and gene silencing. The fourth chapter examines the division of labor in organisms at all levels: within the organelles of a cell, within groups of cells in the guise of differentiation, within groups of individuals in an animal society, and within our culturally determined human societies. The work closes with a charming personal history of sixty years of changes in the field of biology, including the transformation in the ways that research work is funded.

Noted biologist and author John Tyler Bonner has experimented with cellular slime molds for more than sixty years, and he has done more than anyone else to raise these peculiar collections of amoebae from a minor biological curiosity to a major model organism--one that is widely studied for clues to the development and evolution of all living things. Now, five decades after he published his first pioneering book on cellular slime molds, Bonner steps back from the proliferating and increasingly specialized knowledge about the organism to provide a broad, nontechnical picture of its whole biology, including its evolution, sociobiology, ecology, behavior, and development. "The Social Amoebae" draws the big lessons from decades of research, and shows how slime molds fit into and illuminate biology as a whole.

Slime molds are very different from other organisms; they feed as individual amoebae before coming together to form a multicellular organism that has a remarkable ability to move and orient itself in its environment. Furthermore, these social amoebae display a sophisticated division of labor; within each organism, some cells form the stalk and others become the spores that will seed the next generation. In "The Social Amoebae," Bonner examines all these parts together, giving a balanced, concise, and clear overview of slime mold biology, from molecules to cells to multicells, as he advances some unconventional and unexpected insights.

Within a single captivating narrative, John Bonner combines an intensely personal memoir of scientific progress and an overview of what we now know about living things. Bonner, a major participant in the development of biology as an experimental science, draws on his life-long study of slime molds for an understanding of the life cycle-the foundation of all biology. In an age of increasing specialization and fragmentation among subfields of biology, this is a unique work of reflection and integration. Originally published in 1993.

John Tyler Bonner, one of our most distinguished and insightful biologists, here challenges a central tenet of evolutionary biology. In this concise, elegantly written book, he makes the bold and provocative claim that some biological diversity may be explained by something other than natural selection.

With his customary wit and accessible style, Bonner makes an argument for the underappreciated role that randomness--or chance--plays in evolution. Due to the tremendous and enduring influence of Darwin's natural selection, the importance of randomness has been to some extent overshadowed. Bonner shows how the effects of randomness differ for organisms of different sizes, and how the smaller an organism is, the more likely it is that morphological differences will be random and selection may not be involved to any degree. He traces the increase in size and complexity of organisms over geological time, and looks at the varying significance of randomness at different size levels, from microorganisms to large mammals. Bonner also discusses how sexual cycles vary depending on size and complexity, and how the trend away from randomness in higher forms has even been reversed in some social organisms.

Certain to provoke lively discussion, "Randomness in Evolution" is a book that may fundamentally change our understanding of evolution and the history of life.

The howling monkeys of Barro Colorado Island in Panama have a rudimentary language which serves the needs of their social activities. The red deer of Scotland, the seals of the Pribilof Islands, the beavers, the social insects, the army ants and termites, and lastly the colonial and single-celled organisms such as amoebae all meet the same basic biological necessities of feeding, reproduction, and social coordination. Though the means of meeting the requirements are amazingly varied, Mr. Bonner shows that these three functions form a basic pattern that can be recognized in amoebae, in monkeys, and in man-in fact wherever life occurs.

In the current resurgence of interest in the biological basis of animal behavior and social organization, the ideas and questions pursued by Charles Darwin remain fresh and insightful. This is especially true of "The Descent of Man and Selection in Relation to Sex," Darwin's second most important work. This edition is a facsimile reprint of the first printing of the first edition (1871), not previously available in paperback.

The work is divided into two parts. Part One marshals behavioral and morphological evidence to argue that humans evolved from other animals. Darwin shoes that human mental and emotional capacities, far from making human beings unique, are evidence of an animal origin and evolutionary development. Part Two is an extended discussion of the differences between the sexes of many species and how they arose as a result of selection. Here Darwin lays the foundation for much contemporary research by arguing that many characteristics of animals have evolved not in response to the selective pressures exerted by their physical and biological environment, but rather to confer an advantage in sexual competition. These two themes are drawn together in two final chapters on the role of sexual selection in humans.

In their Introduction, Professors Bonner and May discuss the place of "The Descent" in its own time and relation to current work in biology and other disciplines.
