Dr. Charlotte Wolff believes that hand-reading can provide a reliable method of testing temperament and character. This belief is the result of intensive study of the human hand, normal and abnormal, and of the hands and feet of anthropoid apes and monkeys. As a result of these researches, she has been led to infer correlations between hand-characters, physiological conditions and personality trends. In this book she supplies a psycho-physiological theory to account for these correlations and a description of the practical methods of hand-interpretation she has worked out. The whole field covered requires much fuller investigation by independent workers before Dr. Wolff's conclusions can be regarded as valid.
