In foreign countries generally he found more support, though everywhere, it may be admitted, his views must have been regarded as extreme. In Germany glacial investigation was still in a comparatively backward state, but in Penck, Brückner, and Partsch (names subsequently to figure most prominently in the story of the advance of this department of science) he found disciples and supporters of the highest value. The investigations of these geologists had led them independently to the belief in the repeated glaciation of the Alps and the mountains of Central and Eastern Europe. Their chief results were still to appear, but enough was known of their conclusions to define their attitude. In Norway and Sweden, though many notable investigations into glacial geology had been made, no general consensus of opinion had been reached as to the stages into which the glacial history of that country must be subdivided, and Prof. Geikie still found his old friend Axel Blytt the nearest in agreement with his views among the Scandinavian geologists. In France the existence of interglacial periods had warm defenders and keen opponents; but attention was being directed more particularly to the successive phases of palæolithic culture, in the study of which French geologists and anthropologists have always been in the forefront. But in America a school of geologists had arisen in which Prof. James Geikie had found not only warm personal friends but also powerful supporters in his theoretical views, and a most notable contribution to the third edition of _The Great Ice Age_ are the chapters by Prof. Chamberlin (_cf._ Part I., p. 120), in which the glacial history of North America is reviewed. The literature of the glacial geology of that continent has now swelled to enormous dimensions, and to describe the phenomena in a critical and discriminative manner was beyond the powers of anyone who had not devoted many years to a personal examination of the evidence; but in Prof. Chamberlin an exponent was secured who was not only in very substantial agreement with Prof. Geikie in his conclusions, but was also exceptionally familiar with the facts.
