and masses OF all s interior planets 10 calculate ncir
combined influence the body afo resaid This Is q
has been ascertained and by comparing its attractive
power with that OF planet the weight OF the latter
and It's consequent attractive force are approximately
obtained Tho problem solved by Lcverrier was-Given
the attractive in1uence of unknown cody Uranus
what must be the mass and distance OF planet sui
hcient TO produce that influences This process is tho
reverse of the former. Repeatedly did Leverrer ia
IN his Efforts TO locate the strange body or Tue great
number ot possibilities IN the case hc selected several
curacy Of each hypothesis Iaed TO detect the right
ons IL was only after stupendous mental effort pa
tient research and iaborous calculation that he con-
ceved the final conditions which alone could satisfy all
the requirements of the case
HIS PREDICTION VERIFIED.
Not long after the reading of his last memoir he
bad The happiness Of Witnessing the realization
OF his ideal planet His representations had
been made known all over Europe aud the as
tronomers royal began the work Of exploration the
direction assigned by Leverricr On the evening OF
September % Gale, tho astronomer at Berlin, discov
cred the actual planet almost the very spot foretod
ty Levcrrier IL appeared like star of the twelfth
magnitude and at first sight could scarcely be disn
Pnished from fixed star Its motion In Its path
around the was found be slow that IL taxes
the planet l64 years TO make one circuit Applying
kcpers third law, as above stated we accrtan that
IS about thirty times as far from the sun as the
earth s-vz, . I00, COO 900 miles In round numbers.
The extraordinary uilmcnt Of Levcrricrs prediction
created sensation throughout the scientific world
HoSoRs THE VICTOR.
Arago declared thai tho planet should be called
Leverrer; the Grand Duke of Tuscany sent presents
TO the man who had achieved so unprecedented sue
cess in Astronomical labo" the kg OF Denmark sent
him the Order OF Dancbrog, and an the academies of
Europe caused his name 70 be Inscribed on their
lists The Copey Medal sent TO him by the
Royal Society Of England, ard Salvandy then Min
lister OF Public Instruction OF France caused the bus:
OF the triumphant astronomer TO be unveied public
with great pomp and ceremony. Ever since
tho leisure hours of Leverricr have been
devoted 10 Investigations OF the Disturbances of
the planetary worlds from their regular tracks
through space Keen and mastery were his spe
laions concerning Neptune, his missvings in
ton with Vulcan occasioncd calculations of an equally
intricate character, and although he to predict
the existence and the coming transit OF Vulcan, tho
dstu bances OF Jupiter and Uranus had nothing do
with IT, HIS methods OF investigation IN both cases
were similar, however, and, ancr the apprehension
OF his calculations concerning Neptune IL will readily
be understood how by analogous process II been
possible for him to divine the appearance OF the near
est he predicted the discovery Of the TART hest
world OF The solar system. HIS first misgivings as to
knowledge OF the entire solar system his invest

hls new prophecy 10 the FrcDch Academy AMI his in
tcrestng labors in connection with tho supposed dis.
covery OF Vulcan will now be of comprehension
and will form tho subject of future article in the
