NGC 7756. The fourth Earl of Rosse puts this object five arcmin southwest of N7757. The original description reads in full "Another neb about 5' sp." Not much to go on!
There is a star in the area that was taken by MCG and RC1 as N7756, and I've put a colon on it as it seems the most likely object. However, LdR also has measures of two other stars just north of N7757 in his observation of it. Both of them are about the same magnitude as the star to the southwest. This makes me wonder why LdR didn't see them as nebulae as well.
It also lead me to poke around the area a bit. There is a close double star -- quite faint, though -- closer to N7757, and a somewhat brighter and much wider double further south. Neither seems a likely candidate to me, but there isn't much else around that LdR could have seen with the Leviathan.
Listed as No. 68 in Arp's "Atlas of Peculiar Galaxies" (Astrophysical Journal Supplement, vol. 14, 1966.) He remarks "many star-like knots lined up along straight arm."
The RNGC (Sulentic and Tifft 1973) notes that this is a 14.0 mag galaxy. Their coded description reads S,WD,BM,VKNARMS, DKLNS.
