This is a new and important venture undertaken by the A.P.A. with the assistance of Ciba Products Inc., for publication of scientific papers reporting research in progress, especially those presented at regional conferences sponsored by the Association jointly with medical schools. Reports 1 and 4 are concerned with the effects of drugs recently introduced in the treatment of psychiatric disorders and Report 4 with experimental research in psychosomatic medicine. Report 2 (Approaches to the Study of Human Personality) is of interest to the psycho-analyst. It contains a symposium dealing with E. Fromm's views on personality and with cultural, anthropological, semantic and communication approaches. Other papers deal with experimental psychodynamics, cybernetics and constitutional aspects. The symposia are well edited and very readable. They are good value for those interested in the special fields to which they contribute.
