And numerous articles in the Archæological and Anthropological journals of England, France, and Germany. Pp. 8, and 14-15. _Antiquity of Man._--The question concerning the history of Palæolithic man which presses the most immediately for solution, is that which has been just touched upon here: whether the variety of animal remains with which the remains of men are found associated, do really point to an immensely lengthened period of his existence, in this primitive state. We have said that human bones are found associated with those of the mammoth (_Elephas primigenius_), those of the woolly rhinoceros, and with the remains of other animals whose existence seems to imply a cold-temperate, or almost frigid, climate; at another place, or a little lower in the same river bed (the higher gravel beds are the oldest), we may find the bones of the hippopotamus, an animal which in these days is never found far away from the tropics. The conclusion seems obvious: man must have lived through the epoch of change--enormously long though it was--from a cold to an almost tropical climate. Some writers have freely accepted this view, and even gone beyond it to argue the possibility of man having lived through one of the great climatic revolutions which produced an Ice Age. (See the arguments on this head in Mr. Geikie’s _Ice Age_.) And in a private letter, written from the West Indies, Kingsley says that he sees reason for thinking that man existed in the Miocene Era. (See _Life of Kingsley_.) On the other hand, these rather startling theories have not yet received their _imprimatur_ from the highest scientific authorities. There are many ways in which they clash with the story which the stone-age remains seem to tell of man’s primitive life. For instance, the civilization of the caves is to all appearance in advance of that of the drift-beds; and yet, as we have seen (p. 18), the cave men must have existed during the earlier part of the stone age, that of the mammoth. Here we see evidences of a decided improvement, an advance; whereas between the drift-remains associated with the mammoth and those associated with the hippopotamus are seen few or none. P. 9. _Cave-drawings or carvings._--The best representations of these are to be found in the work of Christy and Lartet given above. P. 19. The ideas which savages or primitive men associate with drawings or representations of things (as also with the _names_ of things) are sometimes exceedingly complex and difficult of apprehension--for us. This the following example may show:--
