Transactions 2nd series
Volume 2 page 371. Mr. Taylor states the important fact that the remains
of unknown animals are buried together with the shells in the crag of
Suffolk; but does not mention the nature of these remains. Since these
pages have been at the press, Mr. Warburton, by whom the coast of Essex
and Norfolk has been examined with great accuracy, has informed me that
the fossil bones of the crag are the same with those of the diluvial
gravel, including the remains of the elephant, rhinoceros, stag, etc.)

(**Footnote. Some valuable observations on the formation of recent
limestone, in beds of shelly marl at the bottom of lakes in Scotland,
have been read before the Geological Society by Mr. Lyell, and will
appear in the volume of the Transactions now in the press. See Annals of
Philosophy 1825 page 310.)

Since it appears that the accretion of calcareous matter is continually
going on at the present time, and has probably taken place at all times,
the stone thus formed, independent of the organized bodies which it
envelopes, will afford no criterion of its date, nor give any very
certain clue to the revolutions which have subsequently acted upon it.
But as MARINE shells are found in the cemented masses, at heights above
the sea, to which no ordinary natural operations could have conveyed
them, the elevation of these shells to their actual place (if not that of
the rock in which they are agglutinated) must be referred to some other
agency: while the perfect preservation of the shells, their great
quantity, and the abundance of the same species in the same places, make
it more probable that they lay originally in the situations where we now
find them, than that they have been transported from any considerable
distances, or elevated by any very turbulent operation. Captain de
Freycinet, indeed, mentions that patellae, worn by attrition, and other
recent shells, have been found on the west coast of New Holland, on the
top of a wall of rocks an hundred feet above the sea, evidently brought
up by the surge during violent storms;* but such shells are found in the
breccia of Sicily, and in several other places, at heights too great, and
their preservation is too perfect, to admit of this mode of conveyance;
and to account for their existence in such situations, recourse must be
had to more powerful means of transport.

(* Freycinet page 187. The presence of shells in such situations may
often be ascribed to the bi
