tten on the black-board by the gentleman
from Cambridge (Prof. Pierce) of no practical value, because they cannot
be read by the uninstructed eye? A single line may contain the elements
of the motions of all the heavenly bodies; and the eye of science,
taking its stand-point at the center of gravity of the system, will see
in the equation the harmonious revolutions of all the bodies which
circle the heavens. It is such labors and such generalizations that have
rendered his name illustrious in the history of mathematical science. Is
it of no practical value that the Chief of the Coast Survey (Prof.
Bache), by a few characters written upon paper, at Washington, has
determined the exact time of high and low tide in the harbor of Boston,
and can determine, by a similar process, the exact times of high and low
water at every point on the surface of the globe? Are not these results,
the highest efforts of science, also of the greatest practical utility?
And may we not, then, conclude that _there is nothing truly practical
which is not the consequence of an antecedent ideal_?

Science is to art what the great fly-wheel and governor of a
steam-engine are to the working part of the machinery--it guides,
regulates, and controls the whole. Science and art are inseparably
connected; like the Siamese Twins, they cannot be separated without
producing the death of both.

How, then, are we to regard the superb specimens of natural history,
which the liberality, the munificence; and the wisdom of our State have
collected at the Capitol? They are the elements from which we can here
determine all that belongs to the Natural History of our State; and may
we not indulge the hope, that science and genius will come here, and,
striking them with a magic wand, cause the true practical to spring into
immortal life?

Remarks were also uttered by Prof. CHESTER DEWEY, President ANDERSON,
and Rev. Dr. COX.

And thus ended the Inauguration of the State Geological Hall.

We turn to the Observatory, in regular order of succession.

INAUGURATION OF DUDLEY OBSERVATORY.

The Inauguration of the Dudley Observatory took place under the same
tent which was appropriated to the dedication of the Geological Hall,
and on the day following that event. An immense audience was assembled,
drawn by the announcement of Mr. EVERETT'S Oration.

At a little past three o'clock the procession of _savans_ arrived from
the Assembly Chambe
