Such discoveries have led me, and other geologists, to reconsider the evidence previously derived from caves brought forward in proof of the high antiquity of Man.

So far from having a materialistic tendency, the supposed introduction into the earth at successive geological periods of life,-sensation,-instinct,-the intelligence of the higher mammalia bordering on reason,-and lastly the improvable reason of Man himself, presents us with a picture of the ever-increasing dominion of mind over matter.

It was a profound saying of Wilhelm Humboldt, that 'Man is man only by means of speech, but in order to invent speech he must be already man.'

Man, whose organization is regarded as the highest, departs from the vertebrate archetype; and it is because the study of anatomy is usually commenced from, and often confined to, his structure, that a knowledge of the archetype has been so long hidden from anatomists.

Millions of our race are now supported by lands situated where deep seas once prevailed in earlier ages. In many districts not yet occupied by man, land animals and forests now abound where the anchor once sank into the oozy bottom.

Geology differs as widely from cosmogony, as speculations concerning the creation of man differ from history.
