such animals lived at the time when these
formations were in course of deposition, must have been deposited during
or since the period which Milton speaks of as the fifth day. But there
is absolutely no fossiliferous formation in which the remains of aquatic
animals are absent. The oldest fossils in the Silurian rocks are exuviae
of marine animals; and if the view which is entertained by Principal
Dawson and Dr. Carpenter respecting the nature of the _Eozooen_ be well
founded, aquatic animals existed at a period as far antecedent to the
deposition of the coal as the coal is from us; inasmuch as the _Eozooen_
is met with in those Laurentian strata which lie at the bottom of the
series of stratified rocks. Hence it follows, plainly enough, that the
whole series of stratified rocks, if they are to be brought into harmony
with Milton, must be referred to the fifth and sixth days, and that we
cannot hope to find the slightest trace of the products of the earlier
days in the geological record. When we consider these simple facts, we
see how absolutely futile are the attempts that have been made to draw a
parallel between the story told by so much of the crust of the earth as
is known to us and the story which Milton tells. The whole series of
fossiliferous stratified rocks must be referred to the last two days;
and neither the Carboniferous, nor any other, formation can afford
evidence of the work of the third day.

Not only is there this objection to any attempt to establish a harmony
between the Miltonic account and the facts recorded in the fossiliferous
rocks, but there is a further difficulty. According to the Miltonic
account, the order in which animals should have made their appearance in
the stratified rocks would be this: Fishes, including the great whales,
and birds; after them, all varieties of terrestrial animals except
birds. Nothing could be further from the facts as we find them; we know
of not the slightest evidence of the existence of birds before the
Jurassic, or perhaps the Triassic, formation; while terrestrial animals,
as we have just seen, occur in the Carboniferous rocks.

If there were any harmony between the Miltonic account and the
circumstantial evidence, we ought to have abundant evidence of the
existence of birds in the Carboniferous, the Devonian, and the Silurian
rocks. I need hardly say that this is not the case, and that not a trace
of birds makes its appearance until the far later period whi
