Human Origins #268674

It is evidently important for all who desire to arrive at truth, and to keep abreast of the culture of the day, to have some clear conception of what historical and geological records really teach, and what sort of a standard or measuring-rod they supply in attempting to carry back our researches into the depths of pre historic and Of geological time. I have therefore in this work begun with the historic period, as giving us a solid foundation and standard of time, by which to gauge the vastly longer periods which lie behind, and ascended from this by successive steps through the Neolithic and Palaeolithic ages, and the Quaternary and Tertiary periods, so far as the most recent discoveries throw any light on the mysterious question of Human Origins.
