NGC 4561 = IC 3569. Found by William Herschel on 27 April 1785, observed again by John Herschel in two sweeps, and rediscovered by Frost on a Harvard plate, there are no othe r galaxies in the area as bright or as large as this. It is a peculiar Magellanic irregular with two bright knots; one of these is a superimposed star. These would have led to John Herschel's seeing the object as mottled, and Frost' s description of two stars involved also fits.
Curiously, John Herschel's mean position from his two observations is within a few arcsec of the modern position from GSC, while Frost's photographic -- and presumeably more accurate -- place is further off. It may be this that led both Frost and Dreyer to include the galaxy in the second IC.― NGC Notes by Harold Corwin
