IN a previous paper (Bullock, Clancey and Fleischhacker, 1951) an attempt was made to separate schizophrenic reaction syndromes, due to diagnosable and often successfully treatable disease of known etiology, from idiopathic or cryptogenic schizophrenia. It was shown that the criteria of idiopathic schizophrenia are—
