INTERNATIONAL LAW.

International Law : a Treatise. By L. Oppenheim, LL.D. Vol. I., " Peace." Vol. II., "War." (Longmans and Co. 18s. net per vol.)—Mr. Oppenheim defines the purpose of his work as the presentation of international law "as it is, not as it ought to be." In its nature such law is the recognised practice of nations at any particular epoch, but the author differs from those who insist upon the fluidity of international rules, and endeavours to buil& up his doctrines " on a jurisprudential, which is equivalent to

positive, basis." This is a perfectly legitimate method, especially in a book written for students by a teacher. Sharp definitions are necessary, in any case, as a guide, and Mr. Oppenheim saves himself from the charge of dogmatism by giving a frank statement of other views than his own. The first volume begins with an account of the genesis and sanctions of international law. It then deals with the subjects of the law,—international persons ; the objects of the law, including such matters as the open sea, State territory, and individuals ; the mechanism of international relations, such as diplomatic corps ; and lastly, international transactions, such as treaties. The second volume is concerned with the laws of war, and begins with an account of the machinery for amicable settle- ment, from which it proceeds to the rules which govern the rights of belligerents and neutrals. The arrangement is clear and logical, and the matter of the work is, so far as we have examined it, fully up to date, and presented with acumen and moderation. It may be heartily recommended to all students of the subject who wish a sound, practical exposition of its principles. valuable feature is the bibliography at the head of each chapter, and the full appendix of treaties and statutes.
