The career of Erasmus Darwin (1731-1802) affords an extraordinary glimpse into the intellectual ferment of late-eighteenth- and early-nineteenth-century Britain. As a popular poet, practicing physician, inventor of speaking machines and mechanical birds, essayer of natural history from geology to meteorology, and proponent of an evolutionary theory that inspired his famous grandson Charles, he left a lasting impression on almost every branch of knowledge. His magnum opus, and the synthesis of his myriad interests, is The Botanic Garden (1792) — an epic poem that aims to "enlist the Imagination under the banner of Science." Part I, The Economy of Vegetation, sings the praises of British industry as a dance of supernatural creatures while part II, The Loves of the Plants, wittily employs metaphors of human courtship to describe the reproductive cycles of hundreds of flowers. Darwin supplements his accomplished verses with (often much longer) "philosophical notes" that offer his idiosyncratic perspective on the scholarly controversies of the day. Despite a recent surge of academic interest in Darwin, however, no authoritative critical edition of The Botanic Garden exists, presenting a barrier to further scholarship. This two volume set comprises a complete, meticulously transcribed, reading text — including all the poetry, prose apparatus, and illustrations — along with extensive commentary. Throughout Darwin is situated within contemporary debates about the natural sciences, the "science of the mind", aesthetics, sexuality, politics, and spirituality, among other concerns. This set will be of interest to readers across these and related disciplines as the definitive reference edition of The Botanic Garden and due to its efforts to make the work more practically and intellectually accessible to seasoned and novice readers alike.

This book examines the development of the English patent system and its relationship with technical change during the period between 1660 and 1800, when the patent system evolved from an instrument of royal patronage into one of commercial competition among the inventors and manufacturers of the Industrial Revolution. It analyses the legal and political framework within which patenting took place and gives an account of the motivations and fortunes of patentees, who obtained patents for a variety of purposes beyond the simple protection of an invention. It includes the first in-depth attempt to gauge the reliability of the patent statistics as a measure of inventive activity and technical change in the early part of the Industrial Revolution, and suggests that the distribution of patents is a better guide to the advance of capitalism than to the centres of inventive activity. It also queries the common assumption that the chief goal of inventors was to save labour, and examines contemporary criticism of the patent system in the light of the changing conceptualisation of invention among natural scientists and political economists.
