NGC 4664
NGC 4664, II 39, GC 3196
History and Accurate Positions for the NGC/IC Objects (Corwin 2004)
NGC 4664 = NGC 4665 (which is also = NGC 4624, but 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 N4665 (= H I 142). The star 4.8 seconds preceding (mentioned in both of WH's observations, according to Dreyer) is the clincher here, even if the exact 10 arcmin error in Dec was not in itself enough.
