THE DEDICATION OF THE GEOLOGICAL HALL.

On Wednesday, August 27, 1856, the State Geological Hall of New York

was dedicated with appropriate ceremonies. For the purpose of affording

accommodation to the immense crowds of people who, it was confidently

anticipated, would throng to this demonstration and that of the

succeeding day, at which Mr. EVERETT spoke, a capacious Tent was

arranged with care in the center of Academy Park, on Capitol Hill;

and under its shelter the ceremonies of the inauguration of both

institutions were conducted without accident or confusion; attended on

the first day by fully three thousand persons, and on the second by a

number which may be safely computed at from five to seven thousand.

The announcement that Hon. WM. H. SEWARD would be present at the

dedication of the Geological Hall, excited great interest among the

citizens; but the hope of his appearance proved fallacious. His place

was occupied by seven picked men of the American Association for the

Advancement of Science, one of whom (Prof. HENRY) declared his inability

to compute the problem why seven men of science were to be considered

equal to one statesman. The result justified the selections of the

committee, and although the Senator was not present, the seven

Commoners of Science made the occasion a most notable one by the flow

of wit, elegance of phrase, solidity and cogency of argument, and rare

discernment of natural truths, with which their discourse was garnished.

The members of the American Association marched in procession to the

Tent, from their place of meeting in the State Capitol. On the stage

were assembled many distinguished gentlemen, and in the audience were

hundreds of ladies. GOV. CLARK and Ex-Governors HUNT and SEYMOUR, of New

York, Sir WM. LOGAN, of Canada, Hon. GEORGE BANCROFT, and others as well

known as these, were among the number present. The tent was profusely

decorated. Small banners in tri-color were distributed over the entire

area covered by the stage, and adorned the wings. The following

inscriptions were placed over the front of the rostrum,--that in honor

of "_The Press_" occupying a central position:

GEOLOGY. THE PRESS.

METEOROLOGY. MINERALOGY.

METALLURGY. ETHNOLOGY.

ASTRONOMY.

The following were arranged in various positions on the right and left:

CHEMISTRY. TELEGRAPH.

PHYSIOLOGY. LETTERS.

CONCHOLOGY. HYDROLOGY.

PALÆONTOLOGY. ZOOLOGY.

MICROSCOPY. ICHTHYOLOGY.

ART. MANUFACTURES.

STEAM. AGRICULTURE.

COMMERCE. PHYSICS.

SCIENCE. ANATOMY.

NAVIGATION. BOTANY.

The proceedings of the day were opened with prayer by Rev. GEO. W.

BETHUNE, D.D., of Brooklyn.

Hon. GARRIT Y. LANSING, of Albany, then introduced Professor LOUIS

AGASSIZ, of Cambridge, Mass., who was the first of the "seven men

of science" to entertain his audience, always with the aid of the

inevitable black-board, without which the excellent Professor would be

as much at a loss as a chemist without a laboratory. Professor AGASSIZ

spoke for an hour, giving his views of a new theory of animal

development. He began by saying:--

We are here to inaugurate the Geological Hall, which has grown

out of the geological survey of the State. To make the occasion

memorable, a distinguished statesman of your own State, and Mr.

FRANK C. GRAY, were expected to be present and address you. The

pressure of public duties has detained Mr. SEWARD, and severe

sickness has detained Mr. GRAY. I deeply lament that the occasion

is lost to you to hear my friend Mr. GRAY, who is a devotee to

science, and as warm-hearted a friend as ever I knew. Night

before last I was requested to assist in taking their place--I,

who am the most unfit of men for the post. I never made a speech.

I have addressed learned bodies, but I lack that liberty of

speech--the ability to present in finished style, and with that

rich imagery which characterize the words of the orator, the

thoughts fitting to such an occasion as this. He would limit

himself, he continued, to presenting some motives why the

community should patronize science, and foster such institutions

as this. We scientific men regard this as an occasion of the

highest interest, and thus do not hesitate to give the sanction

of the highest learned body of the country as an indorsement of

the liberality of this State. The geological survey of New York

has given to the world a new nomenclature. No geologist can,

hereafter, describe the several strata of the earth without

referring to it. Its results, as recorded in your published

volumes, are treasured in the most valuable libraries of the

world. They have made this city famous; and now, when the

scientific geologist lands on your shore, his first question is,

"Which is the way to Albany? I want to see your fossils." But

Paleontology is only one branch of the subject, and many others

your survey has equally fostered.

He next proceeded to show that organized beings were organized

with reference to a plan, which the relations between different

animals, and between different plants, and between animals and

plants, everywhere exhibit;--drew sections of the body of a

fish, and of the bird, and of man, and pointed out that in each

there was the same central back-bone, the cavity above and

the ribbed cavity below the flesh on each side, and the skin

over all--showing that the maker of each possessed the same

thought--followed the same plan of structure. And upon that plan

He had made all the kinds of quadrupeds, 2,000 in number, all the

kinds of birds, 7,000 in number, all of the reptiles, 2,000 to

3,000 in number, all the fish, 10,000 to 12,000 in number. All

their forms may be derived as different expressions of the same

formula. There are only four of these great types; or, said he,

may I not call them the four tunes on which Divinity has played

the harmonies that have peopled, in living and beautiful reality,

the whole world?
