Q; Virginia we shall undoubtedly haze brought cut
by Mr.. Rogers. the State Geologist Gypsum, or
plaster Of Paris, IS found in the same formation
but have tine to say nothing Of it.
II In Germany, in England, in Scotland, in Messa-
chusetts and IL Connecticut have been found ex-
4 .ernal impressions spoR the sand stone rock; in
some places resembling ;ha hand OF man, though
of course is rot 10 be SUI posed that it Is the in.
/ preston OF a hand. The unknown animal that
made t!ey evidently walked along the soft sur
face Leaving !nGenia;ions which were sled in by

concavc and the other convex. were pIoduced; and
now when the rock IS split open we ind boin of
them. The animal which made these tracks has
been named Chtro.hsrium, and it remained IN
known until last wear. when Mr.. Owen found It's

think It va. Nothing more than a frog, a large
as al OK 1t is not certain. 20 be sure, that i
would pass for frog now; but in its general con-
tigusation it had strong resemblance 70 this spe-

mails having feet.
Prof SiIIiscn then zweat into description OF
the ornithological discoveries of Prof Hitchcock in
the Valley OF the Connecticut BY which il is seen
that birds existed here tall en7agh 20 walk the
streets ard look in at our chamber windows, and
whose tracks in the rock are now rs distinct rs
those OF n hcnin ba-nyard. have already
given sketch of these il cur report OF Professor
i Hi'chcocks lecture, snail not repeat it.
Passing higher, we find still greater wonders
In the las structure we find remains OF the pe,ri,
fed spawn OF fishes, and theseexisl in great NUN
bers in England aaa France. Wc#frd also The
! PlesioSauruS and the Ichthyosaurss, furnished
WIKI paddles 20 make their way rapidly through
the ocean.
Prof. sjiIliman went on to speak of a species OF
alligator which once existed that had the power
OF contracting the lenses Of its cye=by a compress
sion OF The humors, 70 TO convert it either into a
Il telescope or mcroscope of which .cver,l spc-
cies haze been found at Bristol ,igh;on and York
in England. He mentioned. also, the flying SAT-
rams. w!lich existed when England wa. Only n
these animals swan. He Described, also, the her
bivocrous Saur,ls resembling the modern Tg1lana-
dom but as these topic. were fully treated b. Prof.
Hitchcock, we snail no, give his rcnlarz5upon them
at length.
Near Oxford have been found remains of the
MegeioSaarsus, which was one Of the mar,upial
animals those that have poucios like the opcs-
sum. The kangaroo is of the same class
We pass next u The chalk formation, which
is especially conspicuous in England; giving, by
its white cliffs al! along on both sides the channel.
That beautiful white appearance wb!Gh has cor-
ferrcd upon The ;ast.anchorcd Isle the name OF
Albion. his is the last OF the Marine Stra;n be-
| fore change in tie order OF creation.
These seem to be the detris or ruins OF coral. or
r'ultilopular shells, which We find in Bernluda.-
Coral cliffs exist within the tropics at depth, rs
we now know, not greater than l20 feet. Iney
arc formed by animals, thousands and millions OF
which may be seellat work through the blue depths
OF the calm sea. They often build them in tie
shapc of horse shoe, with the outer edge toward
the trade winds, and thus often formed harbors
for weather-beaten ships-often thirty miles in
diameter. They often rise above the waves, and
form islands upon these birds drop seeds from
other lands: trees grow up and the island is COW
cred with vegetation; animals lizards and other
species are aoatcd by ice, and acolonyis established
aud soon man goes thiher, plants his proud flag
and claims it for his own 1t is not beyond the
reach of probable conjecture that some day-the
Pacific, by the labor OF these animals, may be
bridged over and its wa,ery waste become the scat
of Civilization, Christianity and Empire.
Prof. Sliman thcx spoke at considerable length
of the tertiary rocks and the shells found in them and
referred especially to the phenomena of this kind
discovered in Italy amsng the Appenlncs, and in
the Vale dc MOTTO in Sicily. In the stratum I'M
der Paris which rests upon these rocks, have
been teund the remains of the Paraotheriun, to
which we have no similar animals now. He re-
terrcd also toihe uegatheriumoi> South America,
TO the MaStodon, the Deinoheri1s2, and the an
cient elephant found in Northern Russia, which
had proboscis, which served asat once nose
and hand-thus in fact CARRYING his nose in his
hand. Going still farther up, Prof. S. said there
had been found in the peat boys 9! Ireland The
mains OF man, the last created animal; clad ia
skins, and in perfect preservation.
As much of this subject ha. been treated before
we have only aimed to giva iatclligible sketch
Of the lecturers remarks. He concluded By urg-
Ing upen the attention of those he addressed the
wonders OF the science he had been teaching. In
person Prof. Silliman is tall, stouy built, and hiss
a highly Intellectual and thoughtful countenance.
His delivery is extremely rapid more 50 than any
ether lecturer We have heard he seems TO speak
from In. fullest Knowledge OF his subject and with
an encrg. and enthusiasm which frequently carr
him from the main topic into collateral, though
mos, interesting discussions.
