Originally published in 1915, this book presents the findings of an investigation into outbreaks of tropical sprue, an intestinal inflammation, on the island of Sri Lanka. Bahr analyses the various symptoms of the disease, which appeared to affect predominantly non-native inhabitants of Sri Lanka, as well as suggesting possible solutions and treatments. The text is illustrated with a number of diagrams, drawings and photographs of sprue symptoms and the microscopic organisms found in connection with the disease. This book will be of value to anyone with an interest in medical history or the history of tropical medicine.
