Malamud visited seventy-five North American institutions engaged in study and research on dementia præcox. Basic research, sometimes indistinguishable

from practice, was found 'definitely in the lead', qualitatively and quantitatively, in the field of child development and biochemistry. Numerous investigations are also being conducted in the areas of anthropology, sociology, psychosurgery, constitutional factors, neurology and many others. There is in some instances a regrettable duplication of research efforts and an equally regrettable unawareness of supplementary or correlative work which could with profit be utilized by research workers.
