John Herschel discovered NGC 3935 = h1001 on 29 Apr 1827 and noted "pB; R; psbM." His mean position (from 3 sweeps) is an excellent match with UGC 6843. Alphonse Borrelly's position in AN 1885 appears to have a typo in RA as he placed this object 23 sec of RA west of NGC 3933. Since Borrelly listed this object after NGC 3933 in his short table, he may have communicated the correct RA to Dreyer.

400/500mm - 17.5" (2/24/90): faint, small, elongated WNW-ESE, small bright core.
