Let us take up another current handbook of popular instruction, the volume entitled "Prehistoric Britain," by Dr. Munro, in the Home University Library series. The date of writing is 1913; the same as the date of the Cambridge volume on Lincolnshire. Dr. Munro discusses a certain type of skulls found in various parts of England. "All of these," he says (p. 234), "are usually assigned to the Neolithic period (the later Stone Age), and represent the prevailing type of Englishman at the commencement of that period, and probably also in the latter part of the Palæolithic period (the Early Stone Age). The skulls mentioned may represent British men and women living thousands of years apart. They clearly belong to the same race, which, for lack of a better, we may name 'the river-bed race.' IT IS THE PREVAILING TYPE IN ENGLAND TO-DAY, and from the scanty evidence at our disposal we may presume that it _has been_ the dominant form many thousands of years.... All trace of this race has disappeared in Switzerland, whereas in England, in spite of invasion of Saxon, Jute, Dane and Norman, it still thrives abundantly." And further he says (p. 235): "According to Dr. Keith, Palæolithic blood is as rife in the British people of to-day as in those of the European continent--a conclusion," adds Dr. Munro, "which entirely meets with the present writer's views." Thus we see that, according to two eminent British authorities, the race which inhabited Britain in the Early Stone Age is still the prevalent type in that island, and has not been displaced by Celt or Roman or Anglo-Saxon. [It is, however, due to Dr. Sympson to say that a year earlier, in 1912, Dr. Munro, as he himself observes, thought it "possible that (at the close of the Early Stone Age) the Palæolithic people would shrink back to Europe and thus, for a time, leave a gap in the continuity of human life in Britain" (p. 236); and this, he says, was formerly the general idea.] The second population of Britain, "the people of the Later Stone Age," says Dr. Sympson, "are believed to have been largely of Iberian stock--people, that is, from south-western Europe."
