This is the first trustworthy book on psycho-analysis to be written in French, a fact on which we wish to congratulate the author. It would indeed be a book of high value in any language. It is written only for medical readers. The first chapter gives a general exposition of such matters as repression, condensation, displacement, sublimation, symbolism, etc. The next three are devoted to infantile sexuality, the psychology of dreams, and the parapraxias (slips of the tongue etc.) respectively. Chapters V and VIII deal with symptoms and technique in a quite adequate manner. Chapters VI and VII give the detailed account of the interpretation of a dream, the material being provided by Dr. Odier. We regret to say that, because of the material published in connection with this dream, the book has been forbidden in France. As so little good literature on psycho-analysis exists in French, and as this book is one of which any nation might well be proud, we can only express our regret at this unfortunate attitude, which can only redound to the discredit of our medical colleagues in France.
