3 EXTINCT MONSTERS

the earth. It proved more than that, however; for it showed 
the existence of a great philosophy in Nature which linked the 
past with the present in a scheme that pointed to a continuity of 
life during untold previous ages. All this was directly at variance 
with the prevalent ideas of his time, and consequently his views 
were regarded by many with alarm, and he received a good deal 
of abuse 
a fate which many other original thinkers before him 
have shared. 
It is somewhat difficult for people living now, and accustomed

announced by Cuvier. In his Discourse on the Revolutions of the 
Surface of the Globe, translated into most European languages 
under the title Theory of the Earth, he lays down, among others,

reptiles, and the latter before mammals. 
2, That fossil remains in the more recent strata are those which 
approach nearest to the present type of corresponding living species. 
Teaching such as this gave a new impetus to the study of 
organic remains, and Paleontology, as a science, began with Cuvier. 
The reader is recommended to study Chapters X. and XI. of 
Darwin’s Origin of Species, dealing with the imperfection of the 
record, distribution, and extinction of species, etc. 
One object which the writer has kept in view all through is 
to show how strong is the evidence for Evolution. In fact, it 
is overwhelming; consequently in these days one seldom meets 
a naturalist or a geologist who does not accept the idea of 
Evolution. But when people speak of “ Darwinism ” they do not
