indicate clearly, that they m woe in the tices 
where their remains are depoaiet ge: ae, 
directly opposed to what we see at the presen ay; for noone 
of these animals lives in the northern hentieghdebe but on the 
contrary, in the midst of the torrid zone. It seems therefore, 
that all connexion with climate, is ng Soca to our present 
subject, Nor are we able to escape the > gt rarer of 
5 u 
have been able to exist in the diffe wing couditiias where we 
have found their remains, is compels us to suppose that 
during the og: of a animals upon the earth, there 
was a climate very different from ours; more uniform, in 
which ‘hey cold live aiid ‘propagate as other animals in 
their native country. 
In admitting this as the most probable reason, it follows 
as a necessary eat anatan that we are not obliged in or- 
der to explain the occurrence of these remains in the north- 
te hemisphere, to suppose that the ae transported hpi 
y great currents of water; nor oc 
ee the epochs of their oes from ita ence it 
follows also, we have no farther occasion to go in pursuit of 
proofs of epochs, draw n from the strata, which, it s been 
supposed, contain the revadedit of them. 
Whatever is true in relation to animal remains, must be 
so likewise with regard to vegetables, of which similar gene- 
ra live at present, only in warm climates. 
Such a proposition, which appears to =A very probable, 
gives a new aspect to the notions whic e been formed, 
respecting this carl period, and invites us se enquire into the 
most most probable ses, which might have operated to bring 
about t hé phéliohiens, to which we have just recalled the 
attention “of geologists. More extended researches, and 
more complete discoveries will place us in a condita to 
form a comparative fossil physiology, to be added Pe the 
fore much to be desired that another Cuvier should ap- 
pear to fulfil’a task so important in the natural history of 
the earth.
