Corwin's Notes
=====
NGC 4667 is probably = NGC 4638 with a 2 minute 30 second error in RA. The
Dec's and descriptions are accordant, and there is nothing else in the area
that JH might have described as "B, S, R, psbM; 15 arcsec." So, while the
identity is a guess on my part, I think it is reasonable one.
-----
JH must have a mistake in his reduction as this object occurs in the sweep
(number 61 in Sweep 242) 4 minutes 31 seconds of time preceding NGC 4689. Yet
his reduced positions differ by only 2 minutes 32 seconds of time. As it
happens, NGC 4638 is almost exactly 5 minutes of time preceding NGC 4689,
much closer to JH's observed difference. Given the additional 30 second
error, I'm still not totally convinced that N4667 is another observation of
N4638, but it seems more likely than any other explanation.
