Mr. Geikie has lately gone over the entire ground from the point of view of a geologist. He ranges over a wide field, and appeals in support to writers of acknowledged ability in all branches of learning.27 Yet the impression we gather from his writings is that of ill-defined, but far-reaching antiquity, one necessary to account for the great climatic and geographical changes which he shows us have taken place since the Glacial Age. But he tells us that any term of years he could suggest would be a mere guess. We can not do better than leave the matter here. Perhaps as a result of the research of our present scholars, we may soon have more precise results. These closing essays have impressed on us clearly and distinctly the isolation of the Paleolithic Age. When we reflect on its prolonged duration, its remoteness in time, and its complete severance from the Neolithic and succeeding ages, we are almost ready to wonder whether they were indeed human beings. But beginning with the Neolithic Age, we come to our own era. This primitive culture seems to have been the commencement of our own culture, and so the industries, household implements, and weapons of these ages possess a greater interest to us. We have now completed our inquiry into prehistoric life in Europe, and are ready to turn our attention to other parts of the field. What we have thus far learned shows us how true it is that the past of human life on the globe is full of mystery. We trust that what has been written will enable our readers to form clearer conceptions of life in Europe during these far away times.
