The latest volume in Joseph Needham's magisterial revelation of China's premodern scientific and technological traditions introduces medicine. Five essays are included by Joseph Needham and Lu Gwei-djen, edited and expanded upon by the editor, Nathan Sivin. The essays offer broad and readable accounts of medicine in culture, including hygiene and preventive medicine, forensic medicine and immunology. Professor Sivin's extensive introduction discusses these essays, placing them in their historical and medical context, and surveys recent medical discoveries from China, Japan, Europe and the United States.
