IC 1452 = "NGC 7374B". There is a six-degree error in the IC NPD, one of Dreyer's rare transcription errors. The Comptes Rendus list has the 1860 NPD printed correctly as "79 53".

Once the six-degree error is corrected, IC 1452 is the high-surface-brightness companion to NGC 7374. Bigourdan's position is within two arcsec of the modern ones, and his notes mention not being able to see the 10th magnitude star nearby that Lord Rosse records at PA = 25deg, d = 5 arcmin from NGC 7374; was this an asteroid?

Or was Lord Rosse looking at another galaxy? That kind of misdentification happens now and then in the Birr Castle observations.
