race of animals exclusive ol' every other. Wc noticed an irregular layei-, about a foot thick, literally full
of ammonites :—tlieii- ill preservation implies the action of corrosive acids wliich may have effected the
sirauUaneous deatli of the creatures that inhabited them. Another bed—marl—contains endless echinal
fragments.
But the reader needs to be told that the subjects of our plates were acquired from the lias limestones,
and wc have occasion to add only ttie following admeasurcroonts of such of them as are wrought in
Somerset, and of a section on the coast of Doi-sct;—

Of the last in the series—the black-marl, such colour being occasioned, for tlie most part, by the
bitumen which impregnates it, we have to remark that the organic remains incident to it differ little from
those of the limestones. Yet certain vegetable rarities, in the Misses Philpots' collection, olitaincd from
the black-marl, are so unlike tliose of the other divisions, that tliey deserve the especial attention of
naturalists.
We have now to notice of the lias a number of limestones and marly scams, called white lias, which
are of too uncertain existence and position in reference to the series to have claim of regular relationship
with them. They lie sometimes upon at other underneath the blue limestones, and are of various sizes.
Their appearance a t Pinncy Cliff, near Lyme, and at Platcli Beauchamp, some twenty miles distant, is
singularly opposite. At the former place they are of coarse texture, uneven surface, abounding witli
perfoi-ationsuniformly perpendicular, and witli pebble-likc concretions; at the latter of smooth and perfect
grain and true level. At Lyme affording turrililcs and bivalve shells,—utterly destitute of such and
all other organized relics at Hatch. Both, we hesitate not to say, belong to the same time and cause;
tlie first wore deposited at the instant of a violent volcanic eruption, and owe their vacuities lo caloric;
tlic last quietly settled in a spot more distant from the seat of action.
