THE POLYTECLINIC INSTITUTION.

The inaulpicious state of the weather appears to
have less influence on the numbers by which this
place is visited than on the numbers by which other
exhibitions are attended. Yesterday, notwithstanding
the incessant rain, the galleries were crowded with
the curious, and with a class of persons who are
somewhat beyond the common sight-seekers. Within
these few weeks, during which the institution has
been closed for the purposes of renovation and pre-
paration for the present season, improvements have
been made by the proprietary, both in the arrange-
ment of the numerous things exhibited and by the
introduction of novelties. Many new subjects have
been introduced on which lectures are given, and the
apparatus to illustrate the scientific department has
been considerably enlarged. A number of models of
machines of recent invention has been brought for-
ward, and in addition to the more technical ar-
rangements for scientific instruction, dissolving
views, painted by Mr. C. Smith, have been intro-
duced. The more minute department of the models,
specimens of manufacture and works of art, have also
been attended to with considerable care, and among
these are, not the least praiseworthy, the seal-engrav-
ings of Mr. Giffard, who has cut three very exqui•
site representations of animals—a lion, mountain
goat, and elephant, upon cornelians. The great no-
velty is, however, the table and pendulum, similar to
that exhibited at Paris, by which M. Foucault's ex-
periment demonstrates the rotation of the earth. This
demonstration and the explanation of Dr. Bachhoflner
excited considerable interest, and is certainly worth
the attention of every body by whom science is re-
spected and simplicity of proof admired. The whole
interior of the building is now is the best possible
order, and every accommodation is afforded to visitors.

THE COLOSSEUM.
The proprietors of this elegant place of exhibition
and rational amusement have very judiciously
ovined their season by the restoration within the
dome of the edifice of the celebrated " Picture of
London," by Mr. E. T. Paris, painted from original
sketches taken by Mr. llorner in 1825, from the
cross of St. Paul's Cathedral. It is unnecessary to
give any critical opinion of the merits of this extra-
ordinary
production. At the time of its first exhi-
bition
it received almost unqualified praise from very
competent judge., and the public patronage of several
years confirmed the justice of what was then said.
It has received such retouches as it required, and
will, in the approaching spring and summer be as
attractive, especially to the foreign and provincial
Paris by
Lu
visitors to the metropolis, as it was to the
-
Lon-
doners themselves when first exhibited. in addi-
tion to this picture there is the view of
moonlight, a very beautiful and correct
represen-
tation of that capital, in whichichsomeof the pic-
torial illusions are surprising. The

by a large number of persons,

so good an attendance as
i it deserved,
