geology, prehistoric archaeology and history is so direct that it is impossible to picture early man in this country without using the results of all these three sciences. He intends to use archaeology and geology to "draw aside the veil" covering the situations of the peoples mentioned in proto-historic documents, such as Caesar's Commentaries and the Agricola of Tacitus. Adopting Lyell's scheme of the Tertiary, he divides Pleistocene into Early, Mid- and Late. Only the Palaeolithic falls into the Pleistocene; the Neolithic is in the "Prehistoric Period" subsequent. Dawkins defines what was to become the Upper, Middle and Lower Paleolithic, except that he calls them the "Upper Cave-Earth and Breccia", the "Middle Cave-Earth", and the "Lower Red Sand", with reference to the names of the layers. The next year, 1881, Geikie solidified the terminology into Upper and Lower Palaeolithic: In Kent's Cave the implements obtained from the lower stages were of a much ruder description than the various objects detected in the upper cave-earth ... And a very long time must have elapsed between the formation of the lower and upper Palaeolithic beds in that cave. The Middle Paleolithic in the modern sense made its appearance in 1911 in the 1st edition of William Johnson Sollas' Ancient Hunters. It had been used in varying senses before then. Sollas associates the period with the Mousterian technology and the relevant modern people with the Tasmanians. In the 2nd edition of 1915 he has changed his mind for reasons that are not clear. The Mousterian has been moved to the Lower Paleolithic and the people changed to the Australian aborigines; furthermore, the association has been made with Neanderthals and the Levalloisian added. Sollas says wistfully that they are in "the very middle of the Palaeolithic epoch". Whatever his reasons, the public would have none of it. From 1911 on, Mousterian was Middle Paleolithic, except for holdouts. Alfred L. Kroeber in 1920, Three essays on the antiquity and races of man, reverting to Lower Paleolithic, explains that he is following Gabriel de Mortillet. The English-speaking public remained with Middle Paleolithic. Early and late from Worsaae through the three-stage African system Thomsen had formalized the Three-age System by the time of its publication in 1836. The next step forward was the formalization of the Palaeolithic and Neolithic by Sir John Lubbock in 1865. Between these two times Denmark held the lead in archaeology, especially because
