Some may suppose that this is dating the history of man too far back, making his history too remote; but such is not the case. There is every reason to believe that man existed for ages _before the Glacial epoch_. It must not be supposed that we have yet found remains of the earliest human beings; there is evidence, however, that man existed during the _Pliocene_, if not during the _Miocene_ periods, when hoofed quadrupeds, and Proboscidians abounded, human remains and implements having been found mingled with remains of these animals.[29:1]
