[Although correspondence regarding original papers is always welcome, letters referring to book reviews or critical notices will not normally be published. Letters should not exceed 500 words. An exception has been made because the book in question deals explicitly with the founder of analytical psychology. Also, Dr Adler has had a long personal association with Jung and is, of course, a co-editor of the Collected Works and president of the I.A.A.P. Dr Gordon's reply to Dr Adler's criticism is published below—Editor.]
