JUPITERsS FIFTH SATELLITE.
Prof. Barnard Replies to . Clai mant of
Its Discovery.

SAN JOSE. Cal, Oct. 1.-The following
communication from Prof Barnard con-
corning the discovery of Jupiter's fifth
moon, has been received by the Mercury,
1t is as follows:
Nv attention has been called to the tele-
graphic dispatches going the rounds of the
press to the effect that Mr.. Cartwright, OF De.
trot has presented a claim for the fifth
satellite OF Jupiter, backed no with afti-
davifs of startling nature. l have
already in an article published on
September p shown the folly of such Claims, If
for no other reason than the fact that this satel-
lite can only be seen with the giant telescopes OF
the world None of these claimants have
ever been heard OF before in connec-
ton with any astronomical work-gooc,
bad or indifferent only notice this claim of
NJ Carlwrights because a statement Is made
in tho dispatch referred 10 that is as
de.es,able as 1t 10 couteusntible aud requires
ply The dispatch says: 1T would seem apparent
that these letters were sent to the otservatories
at any rate that one was sent to Lick observatory
and directly inspired the discovery OF the fifth
satellite by Prof Barnard" As to the
dispatch, I would say that up to the
present moment any letter ever sent
10 Lick observatory by Mr.. Cartwright
has never been seen or even hesrd o! BY me, and
Ikpow nothing absolutely of the existence of
any such letter. have no doubt bat that every
observatory of any consequence In the world has
dozens OF such letters its files with claims
OF mythical planet within a couple of degrees
OF Uranus and OF a satellite up near the north
role of the heavens, pointed out by the spirit
on ths star Vega. and OF the discovery
of the double canals Mars with the
naked eve These two letters actually exist In
connection with my statement of the difficulty
of seeing this satellite with even large teies-
copes. l am sure Prot. Young. SO well
known 10 every body, will pardon my quoting
from q letter Just received from him in refer
