The functioning of this clinic is described. It was the third such clinic to be created, preceded only by the Polyclinic (Berlin, 1920) and the Psychoanalytic Clinic (Vienna, 1922). The London clinic has existed since 1926 and trains physicians and lay persons. It has facilities for treatment of adults and, since 1929, of children. It has remained an independent group, avoiding 'nationalization', and has remained a branch of the Institute for Psychoanalysis.
