White, WDS lists a 10th magnitude 10" companion, despite effort this star is not visible

Gaia EDR3 data confirms this 10th magnitude star, listed as B in WDS, is a physical companion with closely matching parallax and proper motion

150mm f/17.6 refractor by Tully 1827

A delicate double star, on the left shoulder-blade of Taurus, indicated by a line drawn from ζ Tauri, in the south horn, under Aldebaran, and continued as far again. A 6, pale emerald; B 10, purple. This elegant but difficult object is 66 ♅. III., and the measures recorded are :

    Pos. 72°45'  Dist. 11".27  Ep. 1782.69

These results, as compared with the above, would have excited attention, but that H. has shown, from the existence of some error, that "no conclusion respecting the motion or rest of this star can be formed." Between the time of ♅.'s observations and my own, I find the following astrometrical details:

    S. Pos. 58°46'  Dist. 9".867  Ep. 1824.98
    Σ.      57°54'        8".897      1830.71
   [WDS     60°           9".20       2015   ]

A small amount of proper motion must not be overlooked:

    P....  RA +0".13  Dec. -0".12
    B....     +0".03       -0".05
   [Gaia DR2  +0".025269   -0".023695]
