New York: D. Appleton & Co, 1929. Very nice copy of this classic of juvenile criminal psychology. Burt achieved great eminence during his lifetime, in 1946 becoming the first British psychologist to be knighted as a reward for his research. Burt's methodologies came into question after his death, however, and it is now widely believed he falsified much of his data, particularly that relating the inheritance of IQ. Nonetheless the current work remains compelling, for both its wealth of detailed personal case studies of British delinquents and the numerous photographic portraits which, though clearly staged, portray genuine subjects and are classics in their genre. Second American printing (first published in London, 1925; the first American printing also appeared that year). Octavo; blue cloth boards, lettered in gilt on spine and front cover; dustjacket; [xviii], 1-619, (2)pp; 15 inserted leaves of photographic plates (halftones); text illus. A tight, Near Fine copy in the scarce dustwrapper, lightly soiled overall with a few nicks to extremities, Very Good to Near Fine.
