This fifth volume abridgement of Joseph Needham's monumental work is concerned with the staggering civil engineering feats made in early and medieval China.

Volumes I and II of the major series: China: its language, geography and history ; Chinese philosophy and scientific thought.

After two volumes mainly introductory, Dr Needham now embarks upon his systematic study of the development of the natural sciences in China. The Sciences of the Earth follow: geography and cartography, geology, seismology and mineralogy. Dr Needham distinguishes parallel traditions of scientific cartography and religious cosmography in East and West, discussing orbocentric wheel-maps, the origins of the rectangular grid system, sailing charts and relief maps, Chinese survey methods, and the impact of Renaissance cartography on the East. Finally-and here Dr Needham's work has no Western predecessors-there are full accounts of the Chinese contribution to geology and mineralogy.

The latest volume in Joseph Needham's magisterial review of China's premodern scientific and technological traditions introduces the history of medicine. Following the deaths of Joseph Needham and Lu Gwei-Djen, a considerable amount of written material on the development of Chinese medicine awaited publication. This material has been gathered together by the editor, Nathan Sivin, in the five essays contained in this volume. They offer a broad and readable account of medicine in culture, including hygiene and preventive medicine, forensic medicine and immunology, and the examinations taken by some Chinese physicians for more than a thousand years. Professor Sivin has edited the essays, expanding them where appropriate and incorporating the results of recent research. His extensive introduction discusses the contributions of Needham and Lu, placing the essays in context, and surveys recent scholarship from China, Japan, Europe and the United States.

The world's preeminent authority on Chinese science explores the philosophy, social structure, arts, crafts, and even military strategies that form our understanding of Chinese science, making instructive comparisons along the way to similar elements of Indian, Hellenistic, and Arabic cultures. A major portion of the book concentrates on Taoist alchemy that led not only to the invention of gunpowder and firearms, but also, through the search for macrobiotic life-elixirs, to the rise of modern medical chemistry.

The second volume of Dr Joseph Needham's great work Science and Civilisation in China is devoted to the history of scientific thought. Beginning with ancient times, it describes the Confucian milieu in which arose the organic naturalism of the great Taoist school, the scientific philosophy of the Mohists and Logicians, and the quantitative materialism of the Legalists. Thus we are brought on to the fundamental ideas which dominated scientific thinking in the Chinese middle ages. The author opens his discussion by considering the remote and pictographic origins of words fundamental in scientific discourse, and then sets forth the influential doctrines of the Two Forces and the Five Elements. Subsequently he writes of the important sceptical tradition, the effects of Buddhist thought, and the Neo-Confucian climax of Chinese naturalism. Last comes a discussion of the conception of Laws of Nature in China and the West.
