has to all our previous suggestions, with such unflinching
magnanimity, we promise you our earnest and hearty cooperation,
and stake our reputation that the scientific success shall fill
up the measure of your hopes and anticipations."

For the attainment of an object so rich in scientific reward and
national glory, guaranteed by men with reputations as exalted and
enduring as the skies upon which they are written, contributions
should be general, and not confined to an individual or a place.

For myself, I offer, as my part of the required endowment, the
sum of $50,000 in addition to the advances which I have already
made; and, trusting that the name which you have given to the
Observatory may not be regarded as an undeserved compliment, and
that it will not diminish the public regard by giving to the
institution a seemingly individual character,

I remain, Gentlemen, your obedient servant,
BLANDINA DUDLEY.

Judge HARRIS then introduced the Orator of the occasion, Hon. EDWARD

THE INSTRUMENTS OF THE DUDLEY OBSERVATORY.

During the Sessions of the American Association, the new Astronomical
Instruments of Dudley Observatory were described in detail by Dr. B. A.
GOULD, who is the Astronomer in charge. We condense his statements:--

The Meridian Circle and Transit instrument were ordered from
Pistor & Martins, the celebrated manufacturers of Berlin, by whom
the new instrument at Ann Arbor was made. A number of
improvements have been introduced in the Albany instruments, not
perhaps all absolutely new, but an eclectic combination of late
adaptations with new improvements. Dr. Gould made a distinction
of modern astronomical instruments into two classes, the English
and the German. The English is the massive type; the German,
light and airy. The English instrument is the instrument of the
engineer; the German, the instrument of the artist. In ordering
the instruments for the Albany Observatory, the Doctor preferred
the German type and discarded the heavier English. He instanced,
as a specimen of the latter, the new instrument at Greenwich,
recently erected under the superintendence of the Astronomer
Royal. That instrument registers obse
