While Freud's theories are much talked about, but few English-speaking physicians have had the opportunity to acquaint themselves with the essentials of Freud's writings, which are scattered and rather fragmentary. Two books dealing with Freud's theories have recently appeared in English and have received favorable comment in these columns. And now appears a translation of Hitschmann's book, which is an effort at a synthetic presentation of the Freudian theory. Truly, at present there is no excuse for any one to discuss Freud without knowing something about him. Hitschmann, it must be stated, is a close friend and pupil of Freud and especially qualified to give a faithful presentation of both the theory and practice of psychanalysis. The translation is exceptionally good, bearing in mind that the majority of English translations from the German are too literal.
