When Ferenczi's Contributions to Psycho-Analysis ran out of print, the publishers, without consulting either the author or translator, re-issued the same book under the title of Sex and Psycho-Analysis. Professor Valentine is not quite so barefaced as this, but the present book is substantially the same—with an additional chapter—as his Dreams and the Unconscious, which, presumably, has also run out of print. In his preface he writes: 'I am glad to find that, after six years, there is little that seems to need correction'. Like the Bourbons, therefore, he has forgotten nothing and learnt nothing, and the criticisms of the blunders he committed in his first edition have left him unmoved. We have nothing further to say of the present volume, except to refer the reader to the review published in this JOURNAL (Vol. III, 1922, p. 77) of the first edition.
