When the marine forms of life are spoken of

having changed simultaneously throughout the world, it must not be supposed that this expression relates to the same

year,

thousandth

or →hundred-thousandth year, or even that it has a very strict geological sense; for if all the marine animals →which live at the present day in Europe, and all those that lived in Europe during the pleistocene period

Nevertheless, looking to a remotely future epoch, there

The fact of the forms of life changing simultaneously, in the above large sense, at distant parts of the world, has greatly struck those admirable observers, MM.
