158 SHORT NOTICES January ground, their statements commonly require modification. Thus, with regard to costume : the statement that tight-fitting clothes are a recent introduction might be questioned by some students of early art. Some phases come and go without evident relation to general progress. The practical result of the whole is certainly one for which the historian would require further justification : that social development and especially the differentiation of functions in the group has in past times not tended to the happiness of the ordinary person, but that we are now approaching a regime of ' social individualism ' in which ' the culture achievements which have been so laboriously acquired us are brought into service for the improvement of the welfare of the individual '. A. G. The first volume of the late Professor L. Oppenheim's International Law, of which we reviewed the first edition in 1907 and the second in 1912, 1 has appeared in a third edition (London : Longmans, 1920), the revision having been carried on by the author until July 1919, and after that date, down to May 1920, by Mr. Ronald F. Roxburgh. A bibliography of Oppenheim's works on international law is added.- F. In 1842 William Jay published anonymously in New York a short book, now carefully reprinted by the Carnegie Endowment for Inter- national Peace, War and Peace : the Evils of the First and a Plan for preserving the Last (New York: Oxford University Press, 1919). The plan was a development of what had been advocated half a century before by Jay's more famous father and, indeed, of far older projects and pre- cedents : it was a plan for inserting in treaties a clause for the submission of consequent disputes to arbitration. As Dr. James Brown Scott, however, points out in a brief introduction, the book played a real part in the progress by which the clause compromissoire became a familiar provision of treaties, and it still has an interest for the student of ' peace movements '. G. The provision of an index, with which, as a ninth volume, Dr. W. P. C. Knuttel has now completed his Catalogus van de Pamfletten-V enameling berustende in de Koninklijke Bibliotheek (The Hague: Nijhoff, 1920), will save much time and trouble to those who work among Dutch pam- phlets. References are given both to names and to the more important subjects, and the printing is admirably clear. H. Newspapers and other periodicals afford a valuable but a vast and confusing mass of information on the history of the last three centuries, and the anonymous Tercentenary Handlist of English and Welsh News- papers, Magazines, and Reviews (London : The Times, 1920) will be heartily welcomed by historical students. It is divided into two sections arranged in chronological order, the first giving the London and suburban press, the second, that of the provinces, and each section has a separate index of titles. The collections of the British Museum have been used as the basis of the compilation, but a large number of periodicals are mentioned which are not to be found there, and in these cases references are given 1 Ante, xxii. 388 ; xxvii. 414.
