at these distant points of the world. In the several successive palæozoic formations of Russia, Western
and North America, a similar parallelism in the forms of life has been observed by several
so it is, according to Lyell, with the
European and North American tertiary deposits. Even if the few fossil species which are common to the Old and New Worlds
kept wholly out of view, the general parallelism in the successive forms of life, in the

→tertiary
would still be manifest, and the several formations could be easily correlated. |

| These observations, however, relate to the marine inhabitants of

the world: we have not sufficient data to judge whether the productions of the land and of fresh water
→at distant points change
in the same parallel manner. We may doubt whether they have thus changed: if the Megatherium, Mylodon, Macrauchenia, and Toxodon had been brought to Europe from La Plata, without any information in regard to their geological position, no one would have suspected that they had

| 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
or
→to the same century,
or even that it has a very strict geological sense; for if all the marine animals
→now living
in Europe, and all those that lived in Europe during the pleistocene period

were
compared with those now
in South America or in Australia, the most skilful naturalist would hardly be able to say whether the
or the pleistocene inhabitants of Europe resembled most closely those of the southern hemisphere. So, again, several highly competent
that the existing productions of the United States are more closely related to those which lived in Europe during certain
tertiary stages, than to
→the present inhabitants of Europe;
and if this be so, it is evident that fossiliferous beds
→now deposited
on the shores of North America would hereafter be liable to be classed with somewhat older European beds. Nevertheless, looking to a remotely future epoch, there
be little doubt that all the more modern
marine
formations, namely, the upper pliocene, the pleistocene and strictly modern beds, of Europe, North and South America, and Australia, from containing fossil remains in some degree allied, and from not
