The English, Disease, and Medicine in Colonial Bengal, 1617 – 1847

Europeans in early colonial Bengal fell prey to new diseases that their limited pharmacopeia, based on an imperfect knowledge of physiology, often failed to treat. This book looks at clinical observations and theories by several English doctors, who, with the encouragement of the East India Company, strove to address these ailments. This enthralling story begins with John Woodall, who never voyaged to India but equipped the surgeons’ chests aboard ships sailing there, and ends with James Esdaile’s contentious work at the experimental Mesmeric Hospital he was permitted to set up briefly in Calcutta.
