This is neither a psychoanalytic book nor can it be called scientific in the strict sense of the word. Yet anyone interested in the psychology of sex will find some interesting material in it. The author reports on a great deal of old literature which has almost fallen into oblivion. He provides a colorful picture of the chaos of ideas regarding sex which existed at the time when Freud wrote his Three Contributions to the Theory of Sex. We learn about some speculations which are not only interesting in themselves but also remarkable as expressions of the psychology of the authors.

Dr. Grant states, 'There are two sex motives, unlike in quality, in duration, and in expression. One of these, here called "amorous", is an urge to possess in a complete, intimate, and lasting sense, manifested physically in nongenital contacts.' He calls the other sex motive 'genital-sex desire'. These conclusions are neither proven nor satisfactory. Yet without agreeing with his conclusions, Dr. Grant's book can be appreciated.
