matter being one
of great historical moment),--and who will, doubtless, in his own good time
and manner, place his calculations before the public.

_Discovery of Le Verrier's Planet._

Mr. Hind announces to the _Times_ that he has received a letter from Dr.
Bruennow, of the Royal Observatory at Berlin, giving the very important
information that Le Verrier's planet was found by M. Galle, on the night of
September 23. "In announcing this grand discovery," he says, "I think it
better to copy Dr. Bruennow's[800] letter."

"Berlin, Sept. 25.

"My dear Sir--M. Le Verrier's planet was discovered here the 23d of
September, by M. Galle.[801] It is a star of the 8th magnitude, but with a
diameter of two or three seconds. Here are its places:

h. m. s. R. A. Declination.
Sept. 23, 12 0 14.6 M.T. 328 deg. 19' 16.0" -13 deg. 24' 8.2"
Sept. 24, 8 54 40.9 M.T. 328 deg. 18' 14.3" -13 deg. 24' 29.7"

The planet is now retrograde, its motion amounting daily to four seconds of
time.

"Yours most respectfully, BRUeNNOW."

"This discovery," Mr. Hind says, "may be justly considered one of the
greatest triumphs of theoretical astronomy;" and he adds, in a postscript,
that the planet was observed at Mr. Bishop's[802] Observatory, in the
Regent's Park, {387} on Wednesday night, notwithstanding the moonlight and
hazy sky. "It appears bright," he says, "and with a power of 320 I can see
the disc. The following position is the result of instrumental comparisons
with 33 Aquarii:

Sept. 30, at 8h. 16m. 21s. Greenwich mean time--
Right ascension of planet 21h. 52m. 47.15s.
South declination 13 deg. 27' 20"."

THE NEW PLANET.

"Cambridge Observatory, Oct. 15.

"The allusion made by Sir John Herschel, in his letter contained in the
_Athenaeum_ of October 3, to the theoretical researches of Mr. Adams,
respecting the newly-discovered planet, has induced me to request that you
would make the following communication public. It is right that I should
first say that I have Mr. Adams's permission to make the statements that
follow, so far as they relate to his labors. I do not propose to enter into
a detail of the steps by which Mr. Adams was led, by his spontaneous and
independent researches, to a conclusion that a planet must exist more
distant than Uranus. The matter is of too great historical moment not to
receive a more f
