dating back to 1900. Of those founded since then, there should be mentioned: L'Homme Préhistorique (Paris), a monthly founded in 1903; La Revue Préhistorique (Paris), a monthly founded in 1906; Praehistorische Zeitschrift (Berlin), founded in 1909; Mannus, Zeitschrift für Vorgeschichte, Organ der Deutschen Gesellschaft für Vorgeschichte (Würzburg), founded in 1909. In December, 1903, the Société Préhistorique de France was founded. It publishes a monthly bulletin; also in 1906 a handbook appeared, Manuel de Recherches Préhistoriques, and since 1905 has held a congress annually, each compte rendu of which forms a large volume of about a thousand pages.
In addition to these new channels, there should be mentioned certain special publications made possible through the generosity of patrons of the science, either private individuals or learned societies. One of these, the joint work of de Villeneuve, Verneau, and Boule, and entitled "Les Grottes de Grimaldi[1] (Baoussé-Roussé)," was due to the initiative of Prince Albert I. of Monaco. The latter is at present promoting a new and important project, which might be styled a paleolithic survey of northern Spain. The work is in charge of a committee consisting of Hermilio Alcalde del Rio, P. Lorenzo Sierra, Abbé Henri Breuil, Abbé Jean Bouyssonie, and Dr. Hugo Obermaier. The report of last summer's campaign[2] is highly gratifying and gives assurance of another publication worthy to rank with that on the caverns of Grimaldi. The Academic des Inscriptions et Belles-Lettres has also become a patron of prehistoric archeology, generously supporting from its funds the joint explorations of French caverns by Cartailhac and Breuil.
This much increased literary output presupposes a corresponding activity in the field, the museum, and the study. A record of the explorations in the field alone would far surpass the limits of this paper. The results have been so comprehensive, so cumulative in their effect, that only the alert have been able to keep pace with the progress. It has been a period of intensive study as well as of generalization. The careful scientific exploration of new stations has led to a revision of old data and often the re-exploration of old localities.
A list of the more notable achievements would include such items as Rutot's contributions to our knowledge of a pre-Chellean industry; those of Penck relating to man and the glacial period; the discovery of paleolithic human remains at Krapina,[3] Mauer (near Hei-
