NGC 6111 is not IC 1210. In a note in IC1, Dreyer says, "In Swift's list IX, the declination for 1890 is given as +63 32.6. It was 62 deg in the MS. communication sent me in 1887." That the more northerly declination is correct is confirmed by the note in Swift's published paper (but not carried over into the NGC) "Double star near south points to it."

Unfortunately, the incorrect declination in Swift's letter to Dreyer has led to two incorrect identifications for the number. The first came from Bigourdan -- his "corrected" position quoted in the IC2 notes is for a star. The second came from the modern catalogues which equated the number with a galaxy that Swift also coincidentally discovered, IC 1210 (it was independently found by Bigourdan, presumeably while searching for NGC 6111). In any case, the two numbers apply to two separate objects.
