Reading edition
"The geologist reckons not by days or by years; the whole six thousand years, which were until lately looked on as the sum of the world's age, are to him but as a unit of measurement in the long succession of past ages." (Sir John Lubbock.)
"It is now certain that the vast epochs of time demanded by scientific observation are incompatible both with the six thousand years of the Mosaic chronology, and the six days of the Mosaic creation." (Dean Stanley.)
