Corwin's Notes
=====
NGC 4409 = NGC 4420. WH found NGC 4409 (= III 17) on 23 Feb 1784; he has only
the one observation of it. He found NGC 4420 (= II 23) a month earlier on 24
January, and made a second observation of it sometime later. JH found N4420,
but not N4409, so speculated that "This (N4420) may possibly be identical
with III 17." Since there is nothing at all in either of WH's positions
(that for N4409 precedes the galaxy by 33 seconds and is 2.5 arcmin north; and
that for N4420 follows the true position by 14 seconds and is 3.8 arcmin
south), and since there are no other galaxies in the area that WH could have
seen, JH's suggestion is probably correct. Dreyer carried it over into the
NGC description, and from there, it was adopted by Reinmuth, Harvard, Carlson,
and RC1.
