So far the quotation. The writer is a man of scientific education, a master of arts, a doctor of medicine, and a Fellow of the Society of Antiquaries. This is the age of science, not of credulity, and in matters of science men of scientific education are believed to require scientific proof before they state anything as a fact. If it is the age of science, it is also the age of invention. The statements made in the passage I have quoted are definite enough. In fairness to their writer, however, I shall quote his next paragraph, in which this definite assurance is somewhat qualified: "The Romans," he writes, "who first reached our shores in B.C. 55, held the land till about A.D. 410; but in spite of the length of their domination they do not seem to have left much mark on the people. After their departure, treading close on their heels, came the Saxons, Jutes, and Angles. But with these, and with the incursions of the Danes and Irish, we have left the uncertain region of the Prehistoric Age for the surer ground of History." From what is said just afterwards on the surer ground of History, we are prepared in some measure to assess the value of what has been said, very definitely indeed, in the uncertain region of the Prehistoric Age: "Of the Celtic population of this county [Lincolnshire]," we are told in continuation, "at the time of the Roman invasion, but few traces are left, thus contrasting greatly with what has happened in counties such as Somerset, Cornwall, and the wilder parts of Wales, and the Lake district, where the Brythons (hence the name Britain) fled before the Roman advance and later from the Saxons. These Celts, belonging to the tribe of Coritani, have left little impression on the names of places (Lincoln itself being an exception), and probably none on the actual people of Lincolnshire. On the other hand, the Saxon invasion and settlement must have been complete early in the sixth century." Now let us consider first what the English reader and student is asked to believe in regard of the effect of strictly historical movements on the population of an English county. "The Romans," we are told, during about four centuries of occupation, "do not seem to have left much mark on the people." The writer's object is to show from what early population elements the modern population is composed. By what tokens does he assure us that the prolonged Roman occupation left no permanent element behind? Is it by the scarcity of Roman noses in the Lincolnshire of to-day? Let us regard the facts.
