Historical Research Notes / Correction for NGC 4736
NGC 4736 = M94.  Wolf includes a good position for this in his fifth list, but
cites neither the Messier nor NGC numbers.  He does have a footnote, though, 
identifying the object as "A.G. Bonn 8688."  The galaxy's nucleus is indeed 
bright enough and small enough that it could be measured precisely and
included in the star catalogue. - Dr. Harold G. Corwin, Jr.
