The current output is reviewed from time to time in relation to tests by Mark A. May, Gordon W. Allport, and certain other psychologists who are especially interested in the field. The _Psychological Index_ can be consulted for the purpose of keeping abreast of the large quantity of published material. The most influential recent book is Kretschmer’s _Physique and Character_. The somatic factors in personality are stated with charm and brevity by E. Miller, _Types of Mind and Body_. Useful summary and critical volumes are by William I. Thomas and Dorothy S. Thomas, _The Child in America_ (New York, 1928), chapters viii-xiii inclusive, and by R. G. Gordon, _Personality_ (New York, 1926).
