Dr. Wulf Sachs has been ambitious, he has set out to record and conduct a psycho-analytic study of an African Negro. From the records given it does not appear that he has achieved his ambition; certainly he used the method of free association, but from what can be gathered, the transference situation was hardly dealt with. In fact the writer reproaches himself that he has not been concerned enough over 'John' as a patient, but only as a subject of research. No true psycho-analysis can be done under these conditions. Notwithstanding this fact, Dr. Sachs has succeeded in getting very original material which makes a book of great interest.
