Corwin's Notes
=====
NGC 4664 = NGC 4665 = NGC 4624 (which see; that's another story). This is
another of WH's early discoveries with a large error in the position. There
is nothing at WH's given position. However, in this case, it is a simple
digit error in WH's recording or reduction. Dreyer correctly convinced
himself that it explains the missing NGC 4664 as a prediscovery observation of
NGC 4665 (= H I 142). The star 4.8 seconds preceding (mentioned in both of
WH's observations) is the clincher here, even if the exact 10 arcmin error in
Dec was not in itself enough.
