Sloths are perhaps the most recognized and loved Central and South American animals, but despite their renown and popularity as cartoon characters, toys and memes, they are not well understood. This book offers a colourful, richly illustrated and wide-ranging account of the biological and cultural history of these fascinating mammals. Alan Rauch explores sloths’ gigantic prehistoric ancestors and their evolution into the lethargic, green-hued creatures that live and survive in forest canopies today. From the tale of how sloths were named after a deadly sin to their current status as unflappable icons of a stress-free lifestyle, Sloth shows how fascinating, engaging and inspiring these animals are.

Nineteenth-century England witnessed an unprecedented increase in the number of publications and institutions devoted to the creation and the dissemination of knowledge: encyclopedias, scientific periodicals, instruction manuals, scientific societies, children's literature, mechanics' institutes, museums of natural history, and lending libraries. In Useful Knowledge Alan Rauch presents a social, cultural, and literary history of this new knowledge industry and traces its relationships within nineteenth-century literature, ending with its eventual confrontation with Charles Darwin's Origin of Species. Rauch discusses both the influence and the ideology of knowledge in terms of how it affected nineteenth-century anxieties about moral responsibility and religious beliefs. Drawing on a wide array of literary, scientific, and popular works of the period, the book focusses on the growing importance of scientific knowledge and its impact on Victorian culture. From discussions of Jane Webb Loudon's The Mummy! and Mary Shelley's Frankenstein, to Charlotte Bronte's The Professor, Charles Kingsley's Alton Locke, and George Eliot's Mill on the Floss, Rauch paints a fascinating picture of nineteenth-century culture and addresses issues related to the proliferation of knowledge and the moral issues of this time period. Useful Knowledge touches on social and cultural anxieties that offer both historical and contemporary insights on our ongoing preoccupation with knowledge. Useful Knowledge will appeal to readers interested in nineteenth century history, literature, culture, the mediation of knowledge, and the history of science.

From Flipper to SeaWorld, dolphins have long captured our hearts. We love these friendly, intelligent mammals, and they seem to return our feelings--they enjoy interacting with swimmers and have been known to encircle people under attack by sharks. Despite our familiarity with dolphins, though, we remain ill-informed about how they evolved, how they function and how they have interacted with humans for millennia. Dolphin dives into the dolphin's zoology, as well as its social and cultural history, to offer a comprehensive view of these delightful creatures. Drawing on his years of experience working with and studying dolphins, Alan Rauch explores their propensity to live in pods and their ability to communicate through a variety of clicks, whistles and other vocalizations. He examines their long relationship with humans, describing how they became the emblem of safe travel and charity, that the ancient Greeks featured them on coins and that Hindu mythology associated them with Ganga, a river deity. As the rise in popularity of dolphinaria during the 1960s allowed the public access to dolphins, they became central characters in films like The Day of the Dolphin and Johnny Mnemonic and outsmarted humans in The Hitchhiker's Guide to the Galaxy. Packed with images and thoughtful insights, Dolphin is a revealing look at one of our favorite sea creatures.
