Similar considerations of action on a
vastly smaller scale are of course appli
cable to terrestial plutonic energy, and
thoroughly dispose of the terrestial “per
petual motion” by which Lyell and other
followers of Hutton, on as sound prin
ciples ns those of the humblest mechan
ical perpetual motionist, tried to find
that the earth can go on forever as it is,
illuminated by the sun from infinity of
time past to infinity of time future, al
ways a habitation for race after race of
plants and animals, built on the ruins of
the habitations of preceding races of
plants and animals.
The doctrine of the “dissipation ener
gy” forces upon us the conclusion that
within a finite period of time past the
earth must have been, and within a fin
ite period of time to come must again
bo, unfit for the habitation of man as at
present constituted unless operations
have been and are to bo performed
which are impossible under the laws
governing the known operations going
on at present in the material world.—
