As a recent resurgence in environmental writing demonstrates, human concern for the natural world has its roots in the nature writing and natural history of the 19th century. The writings of poets, novelists, and natural historians from this era suggest the extent to which 19th-century science connected to a wider Romantic sensibility. This volume gathers importan, and often hard-to-find, scientific works with well-known works of literature and nature writing by authors such as Blake, Wordsworth, Shelley, and Keats.
