on condition that one s.ngle star can be
found, by any astronomer, within 20 deg.
or % deg. ofihis great centre, in which
well determined motion towards the north
exists. His theory indicates that the prop
er motion of stars thus situated must be
towards the south. Such is brief out
line of the wonderful facts announced by
DR.. Meadler. The entire paper will be
translated and published in tho Siderial
Messenger.
NEw PLASEF.-The Paris correspon.
dent ofthe Courier des Elats Unis gives
l5amore particular account than any one
(which has appeared through the English
papers, ola discovery, communicated to
the French Academy Of Science, by Mr..
Leyerrier. This gentleman, at the ses.
sion of June 30, read a paper which the
rep1r.er states fixed in a high degree
the attention aud the interest ofthe assem-.
bly,. The subject was nothing less than
new weird, which has been discovered
by the honorable Academician. There
exists in celestial space a planet that Nc
one has seen and Of which Nj. Leverrier
proves the existence. He5does not boast
ofhaving actually seen it himself, it is in
the depths Of his cabinet, and without o.
pening his window, in combining figures
and foTmu' &c, VI. Leverrler hasEot only dis.
coy cred the planet in question, but has
calculated the orbit and measured the
size of it. 1t is far astronomers BIZ pro-

ance, before giving full faith to the calcu-
lations cfthis trial. He points to obser.
vers the region of the heavens towards
which they must direct their telescopes,
and the precise moment which the star
he announces will te seen 10 pass. This
is TO 90 the first of January, 1647.
Certainlyneyer discovery presents in
the same degree the character of boldness,
and originality, as well as importance in
its results. If the prediction of NJ. Lev
crrier is fulfilled, it will be great tri-
umph for mathematical analysis, and for
the person who has given so new and go
important an example oft. As in all
things ofthe kind, it is proceeding from
| the known to the unknown, that these
discoveries are made. NJ. Leverrier has
been LED to his discovery by deductions
which he has drawn from certain astro.
nomical facts relating to Uranus. This
last planet has been until now despair
TO astronomers. While her sisters pres
ent to the observer regular motions and
revolutions easily TO be followed, Uranus,
by an exception much to be regretted, is
pleased to sport with their calculations,
by inexplicab.e caprices in its march
through space. What can be the cause
of these irregularities? Have scientific

lations! Only to imagine such thing

hold. Nj. Leverrier, who has had the
patience to go through all the details, all
the theory ofUranus, has placed beyond
dispute the precision and exactness ofthe
labors of his predecessors. If the capri
ces of Uranus are net to be imputed TO
any error of our geometricians, how arc
they to be explained Is it the proximity
of Jupiter and Saturn which influences
the movable planet!
None of these suggestions are true
Il is not Jupiter, it is not Saturn, which
causes the irregularities of Uranus in its
celestial pr5msnaie. The cause of all
these vagarities is exactly this unknown
planet, SO ingeniously made known by M.
Leverrier. There is an effect, says the
honorable academician, 'sshere must be a
cause" In discussion, admirable for
its logic and clearness. M. Leverier de-
monstra:ed that the hypothesis of which
Uranus has been the. subject, were un-
founded, and that one was inevitably led
to admit the existence of a planet which
has until now escaped observation, and
that all question is reduced to determining
the place it is to occupy. M. Leverrier
did not stop there; he has undertaken to
point out this place, proceeding by the
way ofexclusion. After having set aside
all the other parts. Of the heavens, he
showed that but one possible place re-
mains. 1t is onthe other side Of Uranus,
at distance double that which separates
Uranus from the sun, where Nj. Leverri-
er has placed the new planet which is
now only to be seen and named. The
task eff NJ. LeFerrier is finished-that Of
the observers has begun. 70
