to the existence,
in at least the same districts, of the present species.

STATE OF THE BONES.

No entire skeleton has been discovered, and very rarely were any two
bones of the same animal found together. On the contrary even the
corresponding fragments of a bone were frequently detected some yards
apart (as for instance those in Figures 2 and 1 Plate 49).

PUTREFACTION HAD ONLY COMMENCED WHEN FIRST DEPOSITED.

On the other hand it would appear from the position of the teeth in one
skull (Figure 4 Plate 48) that they were only falling out from
putrefaction at the time the skull was finally deposited in the breccia,
and from the nearly natural position of the smaller bones in the foot of
a dasyurus (Figure 2 Plate 51) it can scarcely be doubted that this part
of the skeleton was imbedded in the cement when the ligaments still bound
the bones together. The united radius and ulna of a kangaroo (Figure 1
Plate 51) are additional evidence of the same kind; and yet if the bones
have been so separated and dispersed and broken into minute fragments, as
they now appear in this breccia, while they were still bound together by
ligaments, it is difficult to imagine how that could take place under any
natural process with which we are acquainted.

ACCOMPANYING MARKS OF DISRUPTION. EARTHY DEPOSITS.

It may however be observed that the breccia is never found below ground
without unequivocal proofs in the rocks accompanying it of disruption and
subsidence, and that the best specimens of single bones have been found
wedged between huge rocks, where the breccia occurs like mortar between
them, in situations eight or ten fathoms underground.

THESE PHENOMENA COMPARED WITH OTHER EVIDENCE OF INUNDATION.

That changes have taken place in the relative level of land and sea is
evident from the channel of the Glenelg which is worn in the rock to a
depth of five fathoms below the sea level. The sea must have either
risen, or the earth must have subsided, since that channel was worn by
any current of water for it is now as still as a canal, the tide making a
difference of only a few inches.

The features on the shores of Port Jackson extend underwater, preserving
the same forms as they have above it; while the bays and coves now
subject only to the ebb and flow of a tide present extensive
ramifications, and can only be considered the submerged valleys of a
surface originally scooped out by erosion at a period when the land stood
highe
