One more popular account of psycho-analysis. It is a quite adequate, though not particularly well-ordered account, and written with Mr. Gallichan's known capacity. It contains no serious inaccuracies and will doubtless succeed in its aim of popularising a knowledge of psycho-analysis. We would note one historical slip, on page 48; the case to which the author refers was treated forty-two years ago, not twenty-five years, and by Dr. Breuer alone, not by Freud in collaboration with Breuer.
