3. Anthropologists who fully endorse the above views as regards man nevertheless intimate, sometimes, that the apes live in polygamous families, under the leadership of “a strong and jealous male.” I do not know how far that assertion is based upon conclusive observation. But the passage from Brehm’s Life of Animals, which is sometimes referred to, can hardly be taken as very conclusive. It occurs in his general description of monkeys; but his more detailed descriptions of separate species either contradict it or do not confirm it. Even as regards the cercopitheques, Brehm is affirmative in saying that they “nearly always live in bands, and very seldom in families” (French edition, p. 59). As to other species, the very numbers of their bands, always containing many males, render the “polygamous family” more than doubtful further observation is evidently wanted.

5. That extension of the ice-cap is admitted by most of the geologists who have specially studied the glacial age. The Russian Geological Survey already has taken this view as regards Russia, and most German specialists maintain it as regards Germany. The glaciation of most of the central plateau of France will not fail to be recognized by the French geologists, when they pay more attention to the glacial deposits altogether.
