BRITISH STRATIFIED SYSTEMS,

TO WHICH THE FOLLOWING SKETCHES MORE ESPECIALLY REFER.

The subjoined tabulation exhibits the arrangement of the British stratified rocks, as accepted by our leading geologists-minor and local deviations of superposition being subordinated for the sake of distinct comprehension and ready reference :

ORDER AND SUCCESSION OF LIFE,

ESPECIALLY AS REFERRED TO IN THE FOLLOWING SKETCHES.

The subjoined tabulation exhibits proximately the stages at which the great ascending sections of Plants and Animals make their first appearance in the stratified systems:-

[blocks in formation]

Man. Plants and animals of
existing species and distribu-
tion; a few genera recently
extinct.

Placental mammals. Plants
and animals of existing or-
ders; a large proportion,
however, of extinct genera
and species.

Marsupial mammals, birds,
reptiles, fishes, shellfish,
crustacea, zoophytes; palms,
coniferæ, ferns, lycopods,
sea-weeds.
