Corwin's Notes
=====
NGC 4972 = NGC 4954. WH has only one observation of this, and Dreyer has this
to say in the Scientific Papers: "In the sweep (1064), the observation of
I. 274 [= NGC 4648, to which WH refers N4972 in his table] seems to be
inaccurate, but III. 937 [= N4972] is between two well-determined stars (Kasan
2331 and 2388)." Dreyer goes on to work out the position of N4972, and it
turns out to be the same -- within the errors -- as that for N4954 (observed
by JH). Neither WH nor JH saw more than one nebula in the area.
This verified JH's speculation in GC (copied verbatim into NGC) that N4954 and
N4972 could be the same object, and Dreyer commented in the 1912 Monthly
Notices list, "4972 to be struck out (= 4954)."
