r, escorted by the Burgesses Corps. Directly in front
of the speaker's stand sat Mrs. DUDLEY, the venerable lady to whose
munificence the world is indebted for this Observatory. She was dressed
in an antique, olive-colored silk, with a figure of a lighter color, a
heavy, red broche shawl, and her bonnet, cap, &c., after the strictest
style of the old school. Her presence added a new point of interest.

Prayer having been uttered by Rev. Dr. SPRAGUE, of Albany, THOMAS W.
OLCOTT, Esq., introduced to the audience Ex-Governor WASHINGTON HUNT,
who spoke briefly in honor of the memory of CHARLES E. DUDLEY, whose
widow has founded and in part endowed this Observatory with a liberality
so remarkable.

Remarks were offered by Dr. B. A. GOULD and Prof. A. D. BACHE, and
Judge HARRIS read the following letter from Mrs. DUDLEY, announcing
another munificent donation in aid of the new Observatory--$50,000, in
addition to the $25,000 which had been already expended in the
construction of the building. The letter was received with shouts of
applause, Prof. AGASSIZ rising and leading the vast assemblage in three
vehement cheers in honor of Mrs. DUDLEY!

You have a building erected and instruments engaged of unrivaled
excellence; and it now remains to carry out the suggestion of the
Astronomer Royal of England in giving permanency to the
establishment. The very distinguished Professors BACHE, PIERCE,
and GOULD, state in a letter, which I have been permitted to see,
that to expand this institution to the wants of American science
and the honors of a national character, will require an
investment which will yield annually not less than $10,000; and
these gentlemen say, in the letter referred to,--

"If the greatness of your giving can rise to this occasion, as it
