A volume such as the present one confronts the reviewer with a difficult, if not impossible, task; to do it justice it is necessary to cleave in twain a work of distinct, but decidedly uneven, merit. first part of the volume presents, in an objective and scientific manner much of what has hitherto been accessible only in the form of highly purposive, that is, propagandist, literature. Precisely because American thought has tended to be molded, in both the Czarist and Soviet periods, by Great Russian perspectives on men and events Dr. Margolin's calm and factual depiction of the Little Russian, or Ukrainian, point of view furnishes the reader a much needed corrective. Just as the optometrist finds it necessary to overcome long-standing distortions by the use of corrective lenses, so the author, with deep erudition and an independent perspective, brings plainly into view a well focussed picture of what much Muscophil historiography has tended to obscure. Conceived in a firm belief in self-determination, the author's narrative has undergone four decades of political gestation. To say that it is mature is understatement. It can now be brought forth to serve as an effective antidote to the traditional anti-nationality outlook of earlier historians. After initial chapters giving a thumbnail sketch of the Russian Revolution, in which he took an active part, Dr. Margolin, who became, in this period, Assistant Minister of Foreign Affairs of the Ukranian Democratic Republic, traces the Ukranian Liberation movement in its triple aspects, constitutional, military, and diplomatic, with great sympathy and insight. He does this was an authenticity which only a key participant, equpped wth essential source-documents, can provide. fourth chapter (pp. 37-51), dealing with The Ukrainian Delegation at the Peace Conference, 1919, is a genuine contribution alike to the literature on the subject, which is very scarce and to the interpretation of events, which have not, to my knowledge, ever received so synoptic a treatment, or one carried through with such exceptional ability. Of almost equal merit is the fifth chapter (pp. 52-71) dealing with his Diplomatic Mission to the United Kingdom, 1920 which penetratingly depicts the muddled state of affairs not only in the London of the Russo-Polish war period but also in the days of the First Assembly of the League of Nations at Geneva, where the Ukraine 's application for admissioni was given an official hearing, and, after considerable discussion, rejected. These two compact, highly authentic chapters, together with their relevant appendices (pp. 177-197), form the core of the volume and conclude its first part. A useful service is performed by Dr. Margolin in the second part in bringing together between the covers of one book and interpreting with Zeitgeist background, the successive memoranda submitted between 1933
