140 FdSSIL MAMMALIA. 
fossil quadrupeds, however differing in generic, 
or specific details, are uniformly constructed on 
the same general plan, and systematic basis of 
organization as living species ; and that through- 
out the various adaptations of a common type to 
peculiar functions, under different conditions of 
the earth, there prevails such universal confor- 
mity of design, that we cannot rise from the 
perusal of these inestimable volumes, without a 
strong conviction of the agency of one vast and 
mighty Intelligence, ever directing the entire fa- 
bric, both of past and present systems of creation. 
Nothing can exceed the accuracy of the 
severe and logical demonstrations, that fill these 
volumes with proofs of wise design, in the con- 
stant relation of the parts of animals to one 
another, and to the general functions of the 
whole body. Nothing can surpass the perfection 
of his reasoning, in pointing out the beautiful 
contrivances, which are provided in almost end- 
less variety, to fit every living creature to its 
own peculiar state and mode of life. His illus- 
tration of the curious conditions, and concurrent 
compensations that are found in the living Ele- 
phants, apply equally to the extinct fossil species 
of the same genus ; and similar exemplifications 
may be extended from the living to the extinct 
species of other genera, e. g. Rhinoceros, Hippo- 
potamus, Horse, Ox, Deer, Tiger, Hygena, Wolf, 
&c. that are usually associated with the Elephant 
in a fossil state.
