IC 4196 = NGC 4970. Swift found this and two other nebulae (IC 4180 and IC 4197) in the area on 27 February 1898. My guess is that he simply forgot to check the NGC, or else he did check and missed NGC 4970. William Herschel's position is very close to the modern positions, and Swift's is within two arcmin of William Herschel's.
However, Dreyer also missed the identity, as did Howe when he went over the field, presumably in 1899 (his note in MNRAS 61, 31, 1900 where he also corrects the position for IC 4197, Swift's "3rd of 3").
The galaxy is positively identified by Swift's note "11m * near p". Dreyer adopted Howe's distance (4 arcmin) to the star for the IC description.― IC Notes by Harold Corwin
