In England Mr. Geikie has strongly urged the theory that the Glacial Age includes not only periods of great cold, but also epochs of exceptional mildness; and he strongly argues that all the evidence of the River Drift tribes can be referred to these warm interglacial epochs; in other words, that they were living in Europe during the Glacial Age.56 In answer to this it has been stated that the relics of River Drift tribes in Southern England overlie bowlder clay, and must therefore be later in origin than the Glacial Age.57 But, Mr. Geikie and others have shown that the ice of the last great cold did not overflow Southern England,58 so that this evidence, rightly read, was really an argument in favor of their interglacial age.59 The committee appointed by the British Association to explore the Victoria Cave, near Settle, urge this point very strongly in their final report of 1878.60 To this report Mr. Dawkins, a member of the committee, records his dissent, but in his last great work he freely admits that man was living in England during the Glacial Age, if he did not, in fact, precede it.61 Mr. Skertchley, of the British coast survey, in 1879,62 announced the discovery in East Anglia of Paleolithic, implements underlying the bowlder clay of that section. Mr. Geikie justly regards this as a most important discovery.63 Finally Mr. Dawkins, in his address as President of the Anthropological section of the British Association, in 1882, goes over the entire ground. After alluding to the discovery of paleolithic implements in Egypt, India, and America, he continues: “The identity of implements of the River Drift hunter proves that he was in the same rude state of civilization, if it can be called civilization, in the Old and the New World, when the hand of the geological clock struck the same hour. It is not a little strange that this mode of life should have been the same in the forests of the North, and south of the Mediterranean, in Palestine, in the tropical forests of India, and on the western shores of the Atlantic.” This, however, is not taken as proving the identity of race, but as proving that in this morning-time of man’s existence he had nowhere advanced beyond a low state of savagism. Mr. Dawkins then continues: “It must be inferred from his wide-spread range that he must have inhabited the earth for a long time, and that his dispersal took place before the Glacial epoch in Europe and America. I therefore feel inclined to view the River Drift hunter as having invaded Europe in preglacial times, along with other living species which then appeared.” He also points out that the evidence is that he lived in Europe
