This Calendar is a catalogue of the letters the editors of the Correspondence of Charles Darwin have found to date. Information on the source and location of each letter is given, together with a brief summary of the content. First published in 1985, the Calendar has been amended to take account of recently-discovered material and re-interpretations or re-dating of known letters. A new supplement lists over 1000 amendments to the main body of the text, together with over 500 addenda relating to newly- discovered material.

This volume is part of the definitive edition of letters written by and to Charles Darwin, the most celebrated naturalist of the nineteenth century. Notes and appendixes put these fascinating and wide-ranging letters in context, making the letters accessible to both scholars and general readers. Darwin depended on correspondence to collect data from all over the world, and to discuss his emerging ideas with scientific colleagues, many of whom he never met in person. The letters are published chronologically. Darwin died in April 1882, but was active in science almost up until the end, raising new research questions and responding to letters about his last book, on earthworms. The volume also contains a supplement of nearly 400 letters written between 1831 and 1880, many of which have never been published before.

This volume is part of the definitive edition of letters written by and to Charles Darwin, the most celebrated naturalist of the nineteenth century. Notes and appendixes put these fascinating and wide-ranging letters in context, making the letters accessible to both scholars and general readers. Darwin depended on correspondence to collect data from all over the world, and to discuss his emerging ideas with scientific colleagues, many of whom he never met in person. The letters are published chronologically. In 1881, Darwin published his final book, The Formation of Vegetable Mould through the Action of Worms. He reflected on reactions to his previous book, The Power of Movement in Plants, and worked on two papers for the Linnean Society on the action of carbonate of ammonia on plants. In this year, Darwin's elder brother, Erasmus, died, and a second grandchild, also named Erasmus, was born.

Darwin, Then and Now is a journey through the most amazing story in the history of science; encapsulating who Darwin was, what he said and what scientists have discovered since the publication of The Origin of Species in 1859. While recognized as one of the most influential individuals of the twentieth century, little is widely known about his personal life, interests, and motivations. This book explores Darwins driving passion using Darwins own words from The Origin of Species, Autobiography, Voyage of the Beagle and letters. In retracing the roots of evolution from the Greeks, Darwin, Then and Now journeys through the dynamics of the eighteenth century that lead to the publication of The Origin of Species and the succeeding role of key players in the emerging evolution revolution. Darwin, Then and Now examines Darwins theory with more than three-hundred quotations from The Origin of Species, spotlighting what Darwin said concerning the origin of species and natural selection using the American Museum of Natural History Darwin exhibit format. With over one-thousand referenced quotations from scientists and historians, Darwin, Then and Now explores the scientific evidence over the past 150 years from the fossil record, molecular biology, embryology, and modern genetics.

Winner of the 2000 American Studies Network Prize and the Literature and Language Award from the Association of American Publishers, Inc. Early American naturalists assembled dazzling collections of native flora and fauna, from John Bartram’s botanical garden in Philadelphia and the artful display of animals in Charles Willson Peale’s museum to P. T. Barnum’s American Museum, infamously characterized by Henry James as “halls of humbug.” Yet physical collections were only one of the myriad ways that these naturalists captured, catalogued, and commemorated America’s rich biodiversity. They also turned to writing and art, from John Edward Holbrook’s forays into the fascinating world of herpetology to John James Audubon’s masterful portraits of American birds. In this groundbreaking, now classic book, Christoph Irmscher argues that early American natural historians developed a distinctly poetic sensibility that allowed them to imagine themselves as part of, and not apart from, their environment. He also demonstrates what happens to such inclusiveness in the hands of Harvard scientist-turned Amazonian explorer Louis Agassiz, whose racist pseudoscience appalled his student William James. This expanded, full-color edition of The Poetics of Natural History features a preface and art from award-winning artist Rosamond Purcell and invites the reader to be fully immersed in an era when the boundaries between literature, art, and science became fluid.
