SAN JOSE, Oct. 1.-THE following COM
munication from Professor Barnard, con-
corning the discovery of Jupiter's fifth
moon, has been received by the Mercury:
''My attention has been called to tele-
graphic dispatch going the rounds of the
press to the effect that Mr.. Cartwright OF
Detroit has presented a claim for the fifth
satellite of Jupiter, backed up with af1i-
davits of startling nature. have
already, in an article published Septem-
Der 10Th, shown the folly of such claims,
If for no other reason than the fact that
this satellite can only be seen with the
giant telescope of the world. None OF
these claimants have ever been heard of
before in connection with any astronomi-
cal work, good, bad or Indifferent. l only
notice this claim of Mr.. Cartwright's be-
cause a statement is made in the dispatch
referred to that is as deteStible as it is
contemplate, and requires reply.
1.-The dispatch says: 1t would seem
apparent that the letters sent to the OBJ
servatories, at any rate that one sent to
the Lick Observatory, directly inspired
the discovery of the fifth satellite by Pro-
fessor Barnard But as to the dispatch, /
"OulI ssy IDdL ulJ W Tile DTSScIJ lllOiflcEL
any letter ever sent to the Lick ObServa-
tory by Mr.. Cartwright has never been
seen or even heard of by me, and l know
nothing absolutely of the existence of
any such letter. 1 have no doubt but that
every observatory of any consequence in
the world has dozens of such letters on
it's files, with claims, from a mythical
planet within a couple of degrees of
Uranus, and with a satellite up near the
north pole of the heavens, as pointed out
by the spirit on the star Vega, to the dis
covery of double canals on Mars with
the naked eye. These two letters actually
exist.
'In connection with my statement of
the difficulty of seeing this satellite with
even large telescopes, l am sure Profess
sor Young, so well known to everybody,
will pardon my quoting from letter Just
received from him in reference to the dis
covery. His instrument at Princeton is
the third largest in America. 1t is a
twenty-three inch Clark telescope, the
name of the maker being guarantee that
1t is as perfect an instrument as can be
made. He writes:
" L tried my best to see the satellite,
but without success. | also suppose that
the telescopes at Washington, twenty-siX
inch, and the Charlottesville, twenty-five
inch, with mine here, twenty-three inch,
are the only ones in this country which
WOlllu nave me least cnance OF DelDg able
20 see the object. l take it for granted
that in giving its magnitude as the thir-
teentb you mean that it is of the same ap-
parent brightness as the thirteenth mag
nitude star at that distance from the plan
cts limb. If SO, it is quite question
whether | could possibly see it. | rather
think [ could, but am by no means conf
dent that | could
HE writes for positions of the satellite
and lust w here and when to look for If
l have not yet heard of the new satellite
being seen with any telescope in the
world yet, except the Lick, 36-inch. Sup
pose Mr.. Cartwright and Mr.. Cooley
come to definite understanding between
them which of the two is to have the
satellite, the fortunate one then settling
his difference with me? ''
