China is sometimes pictured as a country so backward that only a helping—or forcing—hand from the outside can bring it into the fellowship of civilized nations. No one, however, can read this book by Chinese authors on cholera (huo-luan) without realizing that strong forces are at work from the inside. The discussion of one of the most serious diseases in the Orient is on a high level; it is unpretentious but is lucid, accurate and well abreast of current knowledge. The importance of clean water supplies in the control of cholera is clearly recognized and other factors are discussed with complete understanding and good sense. Many Western readers will find the chapter on the history of huo-luan in China of particular interest.
