The fifth volume of the _History of Spain_, by Rousseau St. Hilaire, includes the period from 1336 to 1649. The professor has been employed ten years on his enterprise; he is lauded by all the critics for his research, method, and style. We have recently spoken of this work at some length in _The International_. The PARIS ACADEMY OF INSCRIPTIONS and Belles Lettres is constantly sending forth the most valuable contributions; to the history of the middle ages especially. It is now completing the publication of the sixth volume of the Charters, Diplomas, and other documents relating to French History. This volume, which was prepared by M. Pardessus, includes the period from the beginning of 1220 to the end of 1270, and comprehends the reign of St. Louis. The seventh volume, coming down some fifty years later, is also nearly ready for the printer. Its editor is M. Laboulaye. The first volume of the Oriental Historians of the Crusaders, translated into French, is now going through the press, and the second is in course of preparation. The greater part of the first volume of the Greek Historians of the same chivalrous wars is also printed, and the work is going rapidly forward. The Academy is also preparing a collection of Occidental History on the same subject. When these three collections are published, all the documents of any value relating to the Crusades will be easily accessible, whether for the use of the historian or the romancer. The Academy is also now engaged in getting out the twenty-first volume of the History of the Gauls and of France, and the nineteenth of the Literary History of France, which brings the annals of French letters down to the thirteenth century. It is also publishing the sixteenth volume of its own memoirs, which contains the history of the Academy for the last four years, and the work of Freret on Geography, besides several other works of less interest. From all this some idea may be formed of the labors and usefulness of the institution. * * * * *
